ASSEMBLY
TILE CUTTING WHEEL
For maximum performance and safety, it is recommended
that you use the 10 in. cutting wheel provided with your
saw. Additional cutting wheels of the same high quality are
available at your local dealer.
WARNING:
Do not use cutting wheels rated less than the no
load speed of this tool. Failure to heed this warning
could result in personal injury. Do not use wheel
with cracks, gaps, or teeth.
WARNING:
To prevent possible electrical hazards, have a
qualified electrician check the line if you are not
certain that it is properly wired.
INSTALLING TILE CUTTING WHEEL
See Figures 23 - 24.
WARNING:
A 10 in. tile cutting wheel is the maximum wheel
capacity 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 wheel guard, while thicker wheels
will prevent the wheel nut 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.
 Turn the wheel guard lock counterclockwise to unlock.
 Pull the wheel guard open to expose the spindle.
 Depress and hold the spindle lock.
 Using the wheel wrench provided, remove the wheel nut.
Release the spindle lock button.
NOTE: Remove the wing nut to release the wheel wrench
from storage.
 Remove the outer washer.
 Slide the cutting wheel onto spindle.
WARNING:
If the washer has been removed, replace it before
placing wheel on spindle. 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.
