Installing paper dust bag
To install the paper dust bag, place the paper dust
bag on the paper dust bag holder with its front side
upward. Insert the front fixing cardboard of the paper
dust bag into the groove of the paper dust bag holder.
(Fig. 6)
Then press the upper part of the front fixing card-
board in arrow direction to hook it onto the claws.
(Fig. 7)
Insert the notch of the paper dust bag into the guide
of the paper dust bag holder. Then install the paper
dust bag holder set on the tool. (Fig. 8 & 9)
Front grip (Fig. 10)
Install the front grip on the tool so that its protrusions
fit into the matching notches in the front of the tool.
Secure the front grip using a screwdriver to tighten
the screw through the hole in the front grip.
Switch action (Fig. 11)
CAUTION:
Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the trigger. Release the
trigger to stop. For continuous operation, pull the trig-
ger and then push in the lock button. To stop the tool
from the locked position, pull the trigger fully, then
release it.
Speed adjusting dial (Fig. 11)
For BO5021 only
The tool speed can be infinitely adjusted between
4,000 opm and 12,000 opm by turning the speed
adjusting dial, which is marked 1 to 5. Higher speed
is obtained when the dial is turned in the direction of
number 5; lower speed is obtained when it is turned
in the direction of number 1. Refer to the figure below
for the relationship between the number setting on
the adjusting dial and the kind of work.

Sanding operation (Fig. 12)
Turn the tool on and wait until it attains full speed.
Then gently place the tool on the workpiece surface.
Keep the pad flush with the workpiece and apply
slight pressure on the tool.
CAUTION:
• Never run the tool without the abrasive disc. You
may seriously damage the pad.
• Never force the tool. Excessive pressure may
decrease the sanding efficiency, damage the abra-
sive disc or shorten tool life.
D
• ON-LOA
The sanding pad rotates clockwise during the loaded
operation, but it may rotate counterclockwise during the
no-load operation.
Polishing operation
For BO5021 only
CAUTION
• Use only a Makita genuine sponge pad, felt pad or
wool pad (optional accessories).
• Always operate the tool at low speed to prevent
work surfaces from heating abnormally.
• Never force the tool. Excessive pressure may
decrease the polishing efficiency and cause motor
overload, resulting in tool malfunction.
1. Applying wax (Fig. 13)
Use an optional sponge pad. Apply wax to the
sponge pad or work surface. Run the tool at low
speed to smooth out wax.
NOTE:
• First, wax a not conspicuous portion of the
work surface to make sure that the tool will not
scratch the surface or result in uneven waxing.
• Always run the tool at low speed. Running it at
high speed may cause the wax to spatter.
2. Removing wax (Fig. 14)
Use an optional felt pad. Run the tool at low
speed to remove wax.
3. Polishing (Fig. 15)
Use an optional wool pad. Run the tool at low
speed and apply the wool pad gently to the work
surface.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
