Protections against other causes
Protection system is also designed for other causes
that could damage the tool and allows the tool to stop
automatically. Take all the following steps to clear the
causes, when the tool has been brought to a temporary
halt or stop in operation.
1. Turn the tool off, and then turn it on again to
restart.
2. Charge the battery(ies) or replace it/them with
recharged battery(ies).
3. Let the tool and battery(ies) cool down.
If no improvement can be found by restoring protection
system, then contact your local Makita Service Center.

Changing the tool speed
The orbital speed can be changed in two modes; high
and low. Choose either mode depending on the applica-
tion and workload.
Press the power/speed select button to switch speed
mode while the tool is running.

Speed level Orbital per minute
2 (High) 14,000 min
1 (Low) 11,000 min
NOTICE:
If the tool is operated continuously
at low speeds for a long time, the motor will get
overloaded, resulting in tool malfunction.
NOTICE:
Select an appropriate speed range for
your sanding operations to avoid overheating
and melting the workpiece. Sanding at high orbital
speed may heat workpiece and melt it at the point of
contact.

ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Installing and removing abrasive
paper
CAUTION:
Always make sure that a sheet of
abrasive paper is installed securely before use.
The paper may otherwise be loosened, removed
easily and subject to slippage, resulting in uneven
sanding operation.
NOTE: Bending the paper beforehand makes attach-
ment easier.
Using abrasive paper without dust-
suction hole
1. Cut a sheet of abrasive paper down to an appro-
priate size.
► Fig.5: 1. Abrasive paper 2. Pad
2. Push and hold down the clamp lever on either
front or rear end of the pad, and slide it away from
the stopper so the clamp is released from its locked
position.
3. Pull the clamp lever outwards as far as possible to
create a space between the clamp and side wall of the
sanding base in which one end of abrasive paper can
be inserted.
4.
Slip one end of the abrasive paper into the space
between the clamp and sanding base.
5. Reposition the abrasive paper so it is finely over-
laid on the pad surface.
6. Set the clamp lever back in a locked position to
clamp the end of abrasive paper securely.
7.
Release the clamp on the other end, and have the
other end of abrasive paper ready to be clamped.
8. Maintain a proper tension on abrasive paper, and
then set the clamp lever on the other end in a locked
position.

9.
Cover the abrasive paper with the punch plate
with its positioning stoppers adjacent to the corner well
fit onto two of the side edges of the pad and sanding
base.
