ASSEMBLY
INSTALLING THE TILE CUTTING WHEEL
See Figures 8 - 9.
WARNING:
A 7 in. tile cutting wheel is the maximum wheel
capacit y of the saw. Never use a wheel that is
too thick to allow wheel washer to engage with
the flats on the spindle. Larger wheels will come in
contact with the splash hood, while thicker wheels
will prevent the wheel bolt from securing the wheel
on the spindle. Either of these situations could
result in a serious accident and can cause serious
personal injury.
 Unplug the saw and remove the bevel table.
 Remove the wing nut and wrenches from the wrench
storage area.
 Place the wheel wrench over the arbor nut, and hold the
wheel wrench upright.
 Slide the arbor wrench onto the arbor.
 Hold the wheel wrench in place and push the arbor wrench
away from you to loosen the arbor nut.
 Remove the arbor nut and outer washer, leaving the inner
washer on the arbor.
WARNING:
Always make sure the inner wheel washer is
installed before placing the wheel on the arbor.
Failure to do so could cause an accident, since the
wheel will not tighten properly. Never use wheels
that have openings, grooves, or teeth on this tool.
 Place the cutting wheel onto arbor with the arrows on
wheel going in the counterclockwise direction.
NOTE: The cutting wheel must be installed all the way
onto the arbor. Check to see that the wheel spins freely
once installed. It should spin freely, with no side-to-side
movement.
 Replace the outer washer. The double "D" flats on the
washers align with the flats on the arbor.
 Replace the arbor nut onto the arbor. Hold the wheel
wrench upright and pull the arbor wrench toward you to
tighten the arbor nut.
 Return the wrenches and wing nut to the wrench storage
area.
