Tool Review: QEP Brutus Tile Saw - Model 61024


Upon assembling it, I found one mis-welded wheel support, on the base frame=
, but QEP didn't hesitate to replaced the frame, quickly. This issue was d=
iscovered late Friday, a week ago, so I had to wait until Monday to report =
the problem to QEP, then wait for the replacement part, which arrived this =
Thursday.

After 3 hours of use, my overall impression of this saw, so for, is Grade C=
. Twenty yrs ago, I used an $80 7" tile saw, to cut tile for my sister's =
flooring, so that's my only comparative example for grading this saw. From=
what I recall, that 7" tile saw would get a grade of B+, at least. I don'=
t recall its make, but I think she still has it... and never used since.

QEP's saw:
The fence, on/for the work table is held in place by one *screw and tighten=
ing this screw is not precise. The fence moves out of alignment when the =
screw is tightened. This may not be an issue with most tile/stone cutting,=
but for a $400 saw, IMO, a 10" long fence should not be 1/8" - 3/16" out o=
f alignment, when tightened to the work surface, to the work table's front =
rail. =20

*This screw tightens directly against a cast aluminum front rail of the wor=
k table. I suspect, over time, the screw will make a depression (dent) or =
depressions (dents), at the various locations, along the front rail, such t=
hat future settings will not be totally accurate. I may be wrong about this=
proffered issue.

The water tray, under the saw, is huge, maybe 10 gallons capacity, and is a=
s wide and as long as the frame support (about 16" W X 32" L X 4" deep)). =
This is way too much volume. Maybe this volume acts as a ballast support, =
thought the whole saw unit is about 100 lbs and is pretty steady, for the w=
ork I'm doing. The highest point of the water pump intake is about 1/4" be=
low the water level. The slightest amount of use "allows" for the water pu=
mp intake to start catching air, then the pump fails to pump water. During=
use, the silt buildup, from the brick I'm cutting, seems to work its way u=
nder the pump, raising it above the water, hence, the pump doesn't pump the=
water any longer. The water tray needs to be deeper. I put a 5 gal. buck=
et next to the saw and submerged the water pump in the bucket, allowing for=
only fresh water to cycle through the pump. *There were several reference=
s, in the instruction manual, about cleaning the pump and water lines, shou=
ld they become clogged with silt. Within the first half hour of use, I had=
to disassemble and clean the pump, twice, for it to continue to pump corre=
ctly. =20

There is a 1" wide space between the blade guard and the motor. The arbor =
shaft is visible, here. As the arbor spins, it catches water and flings it=
, sprays it, toward the operator. My whole front stomach and waist area wa=
s soaked, in a short time of use. I initially was cutting half the thickne=
ss of the brick, then flip the brick to cut the other half. In order to cu=
t only half a brick thickness, I raised the blade, hence the water was spla=
shing higher, nearer my chest and chin. I lowered the blade, hence cutting=
3-1/4" thick, so the water sprayed at a lower area, on my stomach and wais=
t. This water spraying is very much not desirable, especially the amount t=
hat is sprayed. Being drenched, this way, is not desirable, at all.... whi=
ch leads to my most important and significant complaint, so for.

Despite my complaining, so for, the saw works very well. After 3 hours of =
use, I started feeling a tingling electrical shock at the on/off switch. I=
hadn't had that shocking up to that time. I shut the saw off. In the ins=
tructions, there were several references to possible electrical shock, if t=
he power supply grounding was not properly wired. The instructions repeate=
dly mentioned to make sure the electrical supply was properly grounded. I =
don't think my wiring is improperly grounded. I will change to another out=
let on a different circuit, and see if that makes a difference.

The saw was plugged into the same outlet as my jointer and I've never had a=
n issue with electrical shock on the jointer. The jointer has a Baldor mot=
or. There's no tag/plate/ID on the tile saw motor. I am not knowledgeable=
of motors, if this is something of relevance. I see in the below link, Ti=
leGuyTodd comments of a "Liberry" article, but I haven't look at it, to see=
if there's any mention of different motor brands being relevant to my prob=
lem.
http://www.johnbridge.com/vbulletin/showthread.php?t=3D42711

I don't know if the "arbor" water spraying has anything to do with this ele=
ctrical issue. The motor area (and everything else) became wet, from the s=
praying and from other normal wet-working. If my power source is wired inc=
orrectly, I would assume I would have had this problem all along, and not a=
fter 3 hours of use. I am not happy, at all, with this development. Again, =
I will change to another electrical outlet and see what happens.

If anyone has any comments or suggestions, about this electrical issue, fee=
l free to speak. I've cut about 70 brick (pavers) and would like to finish=
. I need to cut about 150 more. =20

I'm not pleased with this latest problem (hence, delay of the job), I've ha=
d, with this saw. If this electrical problem is not with my outlets, then,=
for this $400 saw, I would give it a grade of F.

About 2-1/2 hours ago, I loosened the switch plate and opened the box it's =

I saw an interesting method for loosening arbor nuts when looking at
getting a RAS. Put a wrench on the nut, then give the blade a spin and
let the wrench hit a solid object. The momentum and sudden stop would
loosen the nut.

It might be worth a try if you get into a similar situation.

Yep it works.

Over here, an appliance or power tool that used water would never pass
the approvals process without a fully water resistant switch. Most
manufacturers use a flexible rubber cover over a rocker switch.

*************************************************************
If you are getting a shock off the switch cease using the saw
immediately, its unsafe.
*************************************************************

It probably is related to water being sprayed everywhere by the shaft,
but a sane design would have a flinger disk on the shaft within the guard
or other precautions to stop water travelling along the shaft towards the
motor. Maybe some shield or seal is missing?

There are some good large photos here:
<http://www.amazonsupply.com/qep-61024-24-inch-professional-
folding/dp/B001V5IXIO>
and the manufacturer's page with manual and parts list with exploded view
is:
<http://www.qep.com/products.php?c=1&sub=15&prod=7>

Grounding the frame wont make it safe, in fact it may make it even more
dangerous. When operating it, you usually have one hand on the table and
one on the handle. Reach for the switch with the hand you had on the
handle while your other hand is on the grounded table and if its wet, you
will get a shock straight accross the chest. Running it from a RCD
protected socket or extension lead should at least stop it killing anyone
but it will trip out whenever the control box gets damp.

Its fairly obvious from the pictures and Sonny's followup post:

that the switch and control box is not sealed against water ingress. To be
fit for purpose, the control box and motor assembly needs at least an IP64
rating but from the evidence presented I doubt it even meets IP52.
<http://en.wikipedia.org/wiki/IP_Code>

If you read the reviews on Amazon.com:
<http://www.amazon.com/QEP-61024-24-Inch-Professional-
Folding/dp/B001V5IXIO>
you will see that most of the serious users think its a P.O.S.
e.g.: 3 out of 3 saws owned by one reviewer have had failed bearings and
its cheaper to buy a new motor assembly than get warrenty service (probably
due to shipping costs)

From Sonny's experiance, I'd judge it as a *DANGEROUS* P.O.S. and recommend
immediate rejection and return.

If you have one, and cant return it, if possible scrap it, otherwise:
* *DONT* let the control box get wet at all
* *ALWAYS* use a RCD protected extension lead or adapter with it
* *ALWAYS* wear heavy rubber gloves and rubber boots while using it
* *NEVER* let a family member, employee or friend use it!

re of this, if they've done any kind of testing of the product.=20

Some of the reviews, on Ian's link, is not quite fair, as per my experience=
. =20
1) The table to blade alignment is an easy fix/adjustment.... loosen a bolt=
, align them, then tighten the bolt. It was my fence that is out of alignm=
ent, by about 1/8", because of the single screw tightener. I slipped a pie=
ce of sheet metal between the fence face and the table rail, on one side, a=
nd this readjusted the fence alignment into good enough ~90 degree alignmen=
t.... after all, the brick surfaces aren't perfectly flat and have 90 degre=
e corners.
2) Rollers, for the table mounting, run along a shaft. The roller's housin=
g has a grease zerk, to easily keep it running/rolling smooth. I greased i=
t during assembly and after I finished my cutting. Maybe those complaining=
reviewers need to learn how to use a grease gun and learn maintenance upke=
ep. Greasing that roller housing should be as with any other regularly sch=
eduled cleanup/maintenance/servicing of one's tools, *immediately after usi=

3) As for as motor bearings, I'll need to check that out more carefully. W=
ith the arbor shaft exposed, as it is, maybe the shaft is not sealed, very=
well, at the motor housing. Slurry may be able to wick/creep into the mot=
or bearing area, yet, over extended use, without cleaning it after use, may=
be relevant to that bearing problem. With my limited use, I don't have a =
good reply to this issue.


I made a shield for the arbor shaft "spraying", with a 2X4 piece of sheet m=
etal, and it worked very well. I taped a piece of plastic wrap over the swi=
tch box and that worked well. I plugged the saw into a GFI outlet. I was =
able to finish cutting my remaining (~150) brick. Over all, I am pleased w=
ith the saw, even though I had to modify some initial features. Now that I=

-The saw seems to have enough power. =20
-The functions of the sliding table was fine.... normal, IMO. =20
-The 24" run-space, for large tile cutting, made for an extended reach, for=
me, for cutting the brick and, after several hours, my back was aching, t=
hough I took a few breaks. *At 62 yrs old, reaching to tie my shoes does t=
he same thing, at times.
-There were no further issues with the water pump, after I submerged it in =
a 5 gal. bucket, rather than into the saw's water tray.
-The supplied blade may be cheap, as per some reviewers, but it worked well=
for me and there is minimum wear, as for as I can tell.
-I would be hesitant to loan this saw to anyone of limited skill, experienc=

A GFI breaker should be used in a wet application such as tile saw and
cutting with water.
Tingling is definitely not a GFI fault receptacle.
Wet feet and or grounded with saw will cause this issue.
Wet motor......wet switch.....wet body.....
The water tray sounds odd.

I suggested the Chicago Electric.....Harbor Freight tool.
They look similar although none of the problems were encountered.
The fence was perfect even for cutting small tile and brick.
The water pump was in a corral so to speak, that allowed the solids not to
interfere with the pump motor.
The large volume was great since cutting paver stones created lots of
debris.
All the pump, and motor parts were water proofed, and there was a spray
shield so the operator did not get wet....
Oh well....
get a good circuit, stay dry or wear dry boots...finish cutting.....
move on.

Upon assembling it, I found one mis-welded wheel support, on the base frame,
but QEP didn't hesitate to replaced the frame, quickly. This issue was
discovered late Friday, a week ago, so I had to wait until Monday to report
the problem to QEP, then wait for the replacement part, which arrived this
Thursday.

After 3 hours of use, my overall impression of this saw, so for, is Grade C.
Twenty yrs ago, I used an $80 7" tile saw, to cut tile for my sister's
flooring, so that's my only comparative example for grading this saw. From
what I recall, that 7" tile saw would get a grade of B+, at least. I don't
recall its make, but I think she still has it... and never used since.

QEP's saw:
The fence, on/for the work table is held in place by one *screw and
tightening this screw is not precise. The fence moves out of alignment
when the screw is tightened. This may not be an issue with most tile/stone
cutting, but for a $400 saw, IMO, a 10" long fence should not be 1/8" -
3/16" out of alignment, when tightened to the work surface, to the work
table's front rail.

*This screw tightens directly against a cast aluminum front rail of the work
table. I suspect, over time, the screw will make a depression (dent) or
depressions (dents), at the various locations, along the front rail, such
that future settings will not be totally accurate. I may be wrong about this
proffered issue.

The water tray, under the saw, is huge, maybe 10 gallons capacity, and is as
wide and as long as the frame support (about 16" W X 32" L X 4" deep)).
This is way too much volume. Maybe this volume acts as a ballast support,
thought the whole saw unit is about 100 lbs and is pretty steady, for the
work I'm doing. The highest point of the water pump intake is about 1/4"
below the water level. The slightest amount of use "allows" for the water
pump intake to start catching air, then the pump fails to pump water.
During use, the silt buildup, from the brick I'm cutting, seems to work its
way under the pump, raising it above the water, hence, the pump doesn't pump
the water any longer. The water tray needs to be deeper. I put a 5 gal.
bucket next to the saw and submerged the water pump in the bucket, allowing
for only fresh water to cycle through the pump. *There were several
references, in the instruction manual, about cleaning the pump and water
lines, should they become clogged with silt. Within the first half hour of
use, I had to disassemble and clean the pump, twice, for it to continue to
pump correctly.

There is a 1" wide space between the blade guard and the motor. The arbor
shaft is visible, here. As the arbor spins, it catches water and flings it,
sprays it, toward the operator. My whole front stomach and waist area was
soaked, in a short time of use. I initially was cutting half the thickness
of the brick, then flip the brick to cut the other half. In order to cut
only half a brick thickness, I raised the blade, hence the water was
splashing higher, nearer my chest and chin. I lowered the blade, hence
cutting 3-1/4" thick, so the water sprayed at a lower area, on my stomach
and waist. This water spraying is very much not desirable, especially the
amount that is sprayed. Being drenched, this way, is not desirable, at
all.... which leads to my most important and significant complaint, so for.

Despite my complaining, so for, the saw works very well. After 3 hours of
use, I started feeling a tingling electrical shock at the on/off switch. I
hadn't had that shocking up to that time. I shut the saw off. In the
instructions, there were several references to possible electrical shock, if
the power supply grounding was not properly wired. The instructions
repeatedly mentioned to make sure the electrical supply was properly
grounded. I don't think my wiring is improperly grounded. I will change to
another outlet on a different circuit, and see if that makes a difference.

The saw was plugged into the same outlet as my jointer and I've never had an
issue with electrical shock on the jointer. The jointer has a Baldor motor.
There's no tag/plate/ID on the tile saw motor. I am not knowledgeable of
motors, if this is something of relevance. I see in the below link,
TileGuyTodd comments of a "Liberry" article, but I haven't look at it, to
see if there's any mention of different motor brands being relevant to my
problem.

I don't know if the "arbor" water spraying has anything to do with this
electrical issue. The motor area (and everything else) became wet, from the
spraying and from other normal wet-working. If my power source is wired
incorrectly, I would assume I would have had this problem all along, and not
after 3 hours of use. I am not happy, at all, with this development. Again,
I will change to another electrical outlet and see what happens.

If anyone has any comments or suggestions, about this electrical issue, feel
free to speak. I've cut about 70 brick (pavers) and would like to finish.
I need to cut about 150 more.

I'm not pleased with this latest problem (hence, delay of the job), I've
had, with this saw. If this electrical problem is not with my outlets,
then, for this $400 saw, I would give it a grade of F.

The bucket is a pretty standard remedy, how did dirty water get into it?
The dirty water should be going in the tray, keep the tary drain open,
replenish fresh water inbucket as needed (or let a hose tickle into it
constantly).

Can you relocate the tubing so that the entering water trickles low onto
the blade or onto the piece being cut at or just forward of the blade
edge?

No thoughts about that other than to say it should not be, with or without
a GFCI circuit.

For $400, I'd give it an F- right now.
______________________________________

FWIW, my experiences with tile saws. All were/are used mostly to cut
Saltillo tile which produces even more slurry than your bricks.

Saw #1, 1998
A PlasPlugs table saw type, 4" blade. It worked fine for me, cut a lot,
needed to put on a new blade. It was impossible to do so: the blade was
held on the arbor with a nut but there was no way to hold the arbor to
take off the nut. Hold the blade, arbor still spins. I called PlasPlugs,
the lady said,"Just take off the nut". I explained why I couldn't,she
didn't get it. I junked the saw. (Over priced at $150).

Saw #2, 1998
7" sliding table saw from Harbor Freight. It worked fine but Saltillo
creates so much slurry that the rails got so gunked up it was close to
impossible to slide the table. Stored it for years, gave it to a
contractor friend a couple of years ago, he just did a bath with it, loves
it. Fairly priced at a bit over $100.

Saw #3, 1999
7" bridge saw from Harbor Freight. Unlike their current bridge saws,
there was no water pump. There was a long but narrow steel tray bolted
under the steel table for water and the blade tip ran in that. The tray
required frequent water replenishment, I just kept a jug of water handy.

On the negative side, the water tray was a nuisance to take off and clean;
the steel table and frame was highly disposed to rust.

On the positive side, it didn't sling water at me; away from me, lots but
none at me. It worked well and I'd still be using it if the motor
bearings hadn't given out after 14 years. Fairly priced at $99.

Saw #4, Spring 2014
Another 7" bridge saw from Harbor Freight. They have two, I have the
cheaper...$185+- less a 25% coupon. This one is essentially a reworked
and larger version of saw #3 but the table is aluminum, large plastic tray
under with water pump.

The water pump throws out considerable water but on the blade, not me. I
would prefer less water as Saltillo soaks up water like a sponge and needs
to be dry before I can use it. I have taken to sealing the tile before
cutting which helps a lot but the bottom still soaks up considerable.

It has a decent fence, stainless steel IIRC, but it is shorter than I
would like and there is no stop for repetitive cuts. There was no decent
stop on saw #3 either but it was easy to rig a new fence and make a stop.
I could do the same on this one but it would be harder and since I have
relatively little to do I may not bother. All in all it is a decent saw.
If it had a longer fence and stop I'd give it an A+; as is maybe A- or B+.

Consider an inexpensive chop saw, a diamond blade, a connection to a hose
with a needle valve and short length of 1/4" soft copper tube, to direct
water to the blade right before it contacts the brick. The water keeps the
dust down, and saves the bearings. Only a small amount of water is needed,
so electricity should not be an issue, but always use a ground fault
interrupter with water and electricity.

I have used this system before to cut several hundred bricks at a 22 1/2
degree angle for mitered corners. Still use the saw as my primary cutoff
saw.

The saw needs to be grounded. Very likely there is corrosion or such
if it is a three wire unit. If the green wire isn't connected it needs
to be screwed to the frame.

In the field, the extension cord or the wall plug isn't grounded.

I have instructions on my generator to locally ground into the ground
a stake and tie a point on the frame to the rod. That could be done
on any and all saws as a safety and backup safety item.
