007532
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly against
the side of the workpiece and secure it in position with
the screw on the front of the base. It also makes
repeated cuts of uniform width possible.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Clean out the upper and lower guards to ensure
•
there is no accumulated sawdust which may
impede the operation of the lower guarding
system. A dirty guarding system may limit the proper
operation which could result in serious personal injury.
The most effective way to accomplish this cleaning is
with compressed air. If the dust is being blown out
of the guards be sure the proper eye and
breathing protection is used.
