How to trim wall or ceiling panels
Fig.31
Fig.32
First unplug the tool. Open the blade cover and replace
the existing cutter blade with an optional circular saw
blade 110 mm in diameter.
Refer to the "Removing or installing the blade" section
which was described previously. Remove the rubber
facing from the base. Then close and secure the blade
cover. Now the max. depth of cut is 25 mm.
CAUTION:
Be very careful that the blade has been properly
•
mounted on the tool spindle between the inner
flange and the lock nut. Be sure to securely tighten
the lock nut.
Set the depth of cut to "MAX". Rest the base on the floor
(when trimming the wall panels) or the wall (when
trimming the ceiling panels). Using the floor or wall as a
guide, trim wall or ceiling panels. Feed in the direction of
the arrow.

Fig.34
CAUTION:
Before trimming the panels, check the wall or
•
ceiling carefully to avoid cutting the electrical wires,
nails or other foreign materials.
Always reinstall the rubber facing after trimming the
•
panels. If cutting slots for biscuits without the rubber
facing installed properly on the tool, the tool might
slip unexpectedly on the workpiece, causing
dangerous loss of control of the tool. When
installing the rubber facing, always hook it onto the
inside of the front opening.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
Replacing carbon brushes
Fig.35
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.

To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
