MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
WARNING:

Adjusting the cutting angle

This tool is carefully adjusted and aligned at the factory,
but rough handling may have affected the alignment. If
your tool is not aligned properly, perform the following:
Miter angle
► Fig.36: 1. Hex bolt
Loosen the grip which secures the turn base. Turn
the turn base so that the pointer points to 0° on the
miter scale. Tighten the grip and loosen the hex
bolts securing the guide fence using the socket
wrench.
Lower the handle fully and lock it in the lowered
position by pushing in the stopper pin. Square
the side of the blade with the face of the guide
fence using a triangular rule, try-square, etc. Then
securely tighten the hex bolts on the guide fence
in the order from the right side.

► Fig.38: 1. Turn base 2. Lever 3. 0° adjusting bolt
Lower the handle fully and lock it in the lowered position
by pushing in the stopper pin. Loosen the lever at the
rear of the tool.
Turn the 0° bevel angle adjusting bolt on the right side
of the turn base two or three revolutions clockwise to tilt
the blade to the right.
Carefully square the side of the blade with the top
surface of the turn base using the triangular rule, try-
square, etc. by turning the 0° bevel angle adjusting bolt
counterclockwise. Then tighten the lever securely.

Make sure that the pointer on the turn base point to 0°
on the bevel scale on the arm. If it does not point to 0°,
loosen the screw which secures the pointer and adjust
the pointer so that it will point to 0°.

adjusting bolt
Adjust the 45° bevel angle only after performing 0°
bevel angle adjustment. To adjust left 45° bevel angle,
loosen the lever and tilt the blade to the left fully. Make
sure that the pointer on the arm points to 45° on the
bevel scale on the arm holder. If the pointer does not
point to 45°, turn the 45° bevel angle adjusting bolt on
the left side of the arm until the pointer points to 45°.
