After inserting the paper, make sure the clamping part
hold it securely. Otherwise the paper will be loose and
subject to slippage, resulting in uneven sanding operation.
(Fig. 4)
When using the dust bag, make holes in the abrasive
paper using the punch plate as follows:
1. Set the tool upside down.
2. Place the punch plate over the abrasive paper so that
the bent sides of the punch plate are flush with the
paper edges.
3. Press the punch plate to make holes in the abrasive
paper.
CAUTION:
• Be sure to remove the punch plate before operating the
tool.
Model BO4555 only
NOTE:
Use Makita hook-and-loop sandpaper with this sander.
(Fig. 5)
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)
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.
Installing paper dust bag (accessory)
(Fig. 7)
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. 8)
Then press the upper part of the front fixing cardboard in
arrow direction to hook it onto the claws. (Fig. 9 & 10)
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.
OPERATION
Sanding operation (Fig. 11)
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 inspection or
maintenance.
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.
