MQ SP2 SLAB SAW — OPERATION
Cutting
1. Connect hose from water source (on-board water tank or
external water source) to the hose fitting connection
(Figure 3) of the saw. The source pressure should be
approximately 30-40 psi.
2. Ensure the vinyl water tubes are properly inserted into the
blade guard holes and are clear of any obstructions.
3. Turn water source on (Figure 43).
6. Slowly lower the diamond blade onto the cut line by cranking
the
Raise/Lower handle
CLOCKWISE (Figure 37). When
the handle can no longer be turned, the blade will be at its full
rated depth.
The operator MUST wear
the appropriate protective
equipment and clothing while engaged in sawing. Failure
to do so can result in SERIOUS INJURY.

7. For self-propelled models, follow steps 1-4 of the Traveling
During Cutting (Self-Propelled) section.
For push models, use the Traveling During Cutting (Push)
instructions.
8. The rotation of the blade creates a tendency for the saw to
slightly pull in a particular direction. To ensure a straight line
of sawing, apply pressure against the appropriate side of
the handle bar as you slowly advance the saw forward.
Wet Cutting Operation
ALWAYS saw in a straight line only. SERIOUS DAMAGE to
the blade or saw may occur if the saw is twisted or forced to
cut radius shapes.

WARNING
If the water supply to your blade is interrupted, STOP cutting
immediately
to prevent damage to your blade
and/or saw.
If the engine stalls for ANY reason during cutting, raise the
blade out of the cut before restarting.
When cutting, determine the required cutting depth and use an
appropriately sized blade. Deep sawing is wasteful to the life of
the blade.
The preferred method of sawing is to
Step Cut
in increments of
2” (51 mm). Step Cutting provides the optimum opportunity for the
blade to cut fast and last longest.
Dry Cutting Operation
When dry cutting, follow steps 5-8 of the Wet Cutting Operation
section.
4. Open the
water system valve
on the left side of the console
by moving the lever to the ON position (Figure 44) and ensure
the water is flowing equally to both sides of the diamond
blade.
5. Align the saw along the cut line utilizing the front pointer.
