Model BO4555 only
NOTE: Use Makita hook-and-loop sandpaper with
this sander.
► Fig.5: 1. Velcro sandpaper 2. Base
1. Set the tool upside down so that the pad is on top.
2. Position the sandpaper to fit the shape of the
base. Be sure to align the holes on the sandpaper
with the holes on the pad (the dust will be sucked
into these holes; it is therefore important to leave
them open).
3. Press the paper firmly over the pad.
To remove the sandpaper:
1. Set the tool upside down so that the sandpaper is
on top.
2. Grasping one corner of the sandpaper, peel it from
the pad.
NOTE:
• If the sandpaper is in good condition, save it for
further use.
Dust bag (accessory)
► Fig.6: 1. Dust bag
The use of the dust bag makes sanding operations
clean and dust collection easy. To attach the dust bag,
fit the bag's entry port onto the dust spout on the tool.
Make sure that the hole in the bag's entry port is just
over the pimple-like protrusion on the dust spout.
For the best results, empty the dust bag when it
becomes approximately half full, tapping it lightly to
remove as much dust as possible.

OPERATION

Sanding operation
► Fig.15
CAUTION:
• Never run the tool without the abrasive paper.
You may seriously damage the pad.
• Never force the tool. Excessive pressure may
decrease the sanding efficiency, damage the
abrasive paper and/or shorten tool life.
Hold the tool firmly. Turn the tool on and wait until it
attains full speed. Then gently place the tool on the
workpiece surface. A finishing sander is generally used
to remove only a small amount of material at a time.
Since the quality of the surface is more important than
the amount of stock removed, do not bear down on the
tool. Keep the base flush with the workpiece at all times.

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