The lock lever on the riving knife may become difficult to
lock securely after extended use due to sawdust or debris
falling into the plates.
 Unplug the saw.
 Unlock the lever to remove the riving knife.
 Wipe the area with a clean dry cloth or use compressed
air to blow away debris.
 Clean the riving knife.
 Reinstall the riving knife and turn the lever to lock the
riving knife in place.
NOTE: If the lock lever is difficult to move or will not
fully close after the plates have been cleaned, contact
customer service.
WARNING:
Do not use the saw if the lock lever does not
fully close. Doing so may cause serious personal
injury.

CLEANING THE DUST CHUTE

See Figure 92.
This saw features a dust chute for convenience in discharging
sawdust. A standard shop vac can be attached to the chute,
located under the saw.
During periods of extended use, the dust chute should be
emptied and cleaned to prevent buildup of sawdust and to
make sure there are no obstructions or other small offcuts
that may have fallen into the throat plate opening that could
hinder maximum performance.
To clean the dust chute:
 Unplug your saw.
 Using the 4 mm hex key, remove the screws that secure
the back panel.
 Inspect the dust chute and attached dust collection
devices to clear away sawdust or other debris.
 Replace the back panel.
