OPERATION
Once your sliding tile saw is completely assembled, we suggest to get the
water tray
and laser guide s~tup properly beforeattempting to operate.
WATER PUMPWATER SUPPLY
Warning! To prevent excessive wear on the blade, make sure to maintain a
continuousflow of water on the blade duraing all operations. Never cut a tile
without continuous
water flow?
Warning!
Make sure the power cord is positioned to remain dry during
operations.Severe personal injury
or death can occur if the power cord or the
operatorof the tile
saw should become wet.
1) Make sure the water pump is plugged to the quick-connectplug attached to
the motor and that the water hose is properly cannected tothewater pump.
2) Positionthe pump so that it does not interferewith the motion of the sliding
table while cutting.
3) Fill the water tray with enough water so that the pump is completely
submerged, but nottoo much
so that the water tray overflows.
4) Plugthe power cord into a power source, turn the tile saw on and noticethe
rate
of water flow. If it water flow seems insufficientor too much, the water
flow can be adjusted by the pump flow gauge (A) Fig.8. A clockwise
adjustment increases the water flow
and a counterclockwise adjustment
decreasesthe water flow.
USER GUIDE OPERATlON AND ADJUSTMENT
Warning? Do not stare directly intothe laser beam.
1. Mark the line of the cut on the tile.
2. Turn on the laser guide system by pressingthe red switch (A) Fig.9andalign
the line of cut on
the tile with the laserguide beam.
3. Plug in the machine and start the motor.
4. When the blade is at its maximum speed (approx. 2 sec.) slide the table
towards the blade.
5. After completion, switch ofl the laser guide system and the motor and wait
for
the blade to come to a complete stop.
The laser guide system supplied with your tile saw is battery operat4 (2 AAA
batteries supplied). Only turn on the laser guide system only after you have
placed
or are aboutto place a workpiece on the table. To changethe batteries:
1. Removethe lases batterysnap-on cover.
2. Replace both AAA batteries.
3. Reptace the battery cover.
AOJUSTIMG LASER TRAJECTORY
Figure

If your laser guide does nor seem to be aligned with the blade kerf, a small
adjustment can be made.
1. Loosen cap screw (B) Fig.9 found on the right side the laserguide.
2. Place a seap piece of tile on the table and slide the table towardsthe blade.
3. Turn laser tip dial (C) until the laser beam is aligned with the saw blade
(blade
kerf), hold the laser dial and retighten cap screw (B) to prevent the
laser dialfrom
moving.

OPERATIONIMAINTENANCE
Cutting Tiles:
1. Placethe markedtile an the table and brace it againstthe rear of the table. Turn an laserguide and alignthe cut markwith the laser beam.
2. Once the tile saw has been turned on, allow the bladeto speed up to full speed. Make sure that the pump issupplying a continuous flow of
water
to the blade.
3. Keepingyour handsclear of the blade, slfde the table and the tile towardsthe blade.Feedthe tile intothe blade very slowly. Do notforce it.
If the rotationalfeed of the bladeslows down significantly,then you are forcing the tile.
4. While cutting, make sure the blade remainswet. If tt runsdry, check the action of the pump and water levelof the water tray.
5. If the motor stops suddenly, flip the power switch to the "off" position. Check power supply includingthe circuit breaker, wait approximately
15 minutes and pushthe reset button.
Using the 90n Rlp Guide:
If you Rave to cut a number of tiles ta the same dimension, using the 90Vip guide (A) Fig.? 0 may save you a significant amount of time.
1. Mark the first tile to the correct dimensions,allowing space tor grout.
2. W~th the motor turned off, place the marked tile on the table against the fence.
Turn on laser guide and align
the cut mark with the laser beam.
3. Loasenthe lockingknob (B) on the 90Q rip guide. Placethe hooked portion of the
rip guide over the upturned edge of the table, on the side of the cutting groove
where you haveplaced
the part of the markedtile that you intendto keep and use
after cutting. The 90Q rip g~ide will be parallel to the tile and perpendicularto the
fence.
4. Slidethe rip guide alongthefence untilit abuts thetile, makingsurethat the mark
on your tile remains in linewith the laser beam and blade.
5. Tightenthe rip guide knob.
6. When you are satisfiedthat the tile is alignedwith the laser beam and the blade,
and the rip guide is in place,
and it is safe to do so, turn on the tile saw. Cut the
tile
as describedin previous instructions.
7. Make sure that the rile has been cut to proper dimensions before using the rip
guide to cut your other tiles. Periodicallytest the fit of each tile as you continue
cutting,to
be sure the rip guide has not moved.
Figure 10
Angle Cutting, Using the 45Q Rip Guide:
Use the
45P rip guide (C) for cutting anglededgeson your tiles.
1. Attach the 45° ripguide to the fence as you did the 90Q ripguide, usingthe lock knob (D) to holdthe rip guide in place.
2. Use the cutting groove inthe rnrddle of the table to bracethe edge of your tile as youslide the tile and the table towards the blade.
SAW MAINTENANCE
WARNING: DO NOT SERVICE, CLEAN, OR MAINTAIN THE SAW WITHOUT FIRST TURNING OFF THE MOTOR AND UNPLUGGING THE
SAW FROM ITS POWER SOURCE. FATLURE TO DO SO MAY RESULT IN SERIOUS 1NJURY TO THE OPERATOR.
For the longest lifeandbest perlormance,clean the saw after every use. Wipe off all exteriorsurfaces and keep thecuttingtable cleanand free
of tile chips and debris. Wipe
off hththe gurde bars and the rollers on the cutting table. Always check the bladefor cracks or signs of fatigue.
DQ'S AND DON'TS FOR DIAMONDBLADES
DO'S
inspect bladesdaily for cracks or uneven wear.
Always use manufacturers recommendation for matching the rfgM
blade with the rlght materialbeingcut.
Inspect the arbor shaft for unevenwear beforemountingthe blade.
Always use bladeswith the correct arbor size on a compatible arbor
shaft.
Make sure the blade is mounted with the rotation arrow in the
proper direction and is securely tightened with the combination
wrench.
Always wear the proper safety equipment at all times when
operating the saw.
Periodicallycheck the bladefor cracks or bondfatigue.
Always have a continuousflow of water on both sides of the blade
beforecutting material.
DON'TS
Do notoperate the saw without all safetyguards in position.
Do notoperatethe saw with blades larger than 7".
Do not cut dry with the suplied blade.
Do not force the material into the blade. Letthe blade cut at its own
speed.
Do not cut material not recommended by the blade manufacturer.
