Replacing Carbon Brushes; Maintenance - Makita 5402NA Instruction Manual

Rip fence (Guide rule)
► 1. Clamp screw 2. Rip fence (Guide rule)
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 unplugged
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.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Adjusting for accuracy of 90° cut
(vertical cut)
This adjustment has been made at the factory. But if it is off,
adjust the adjusting screw with a hex wrench while squaring
the blade with the base using a triangular rule, try square, etc.

time. Use only identical carbon brushes.
