Operation - Makita BO4555 Instruction Manual

Installing or removing abrasive paper
Fig.2
Open the paper clamp by raising on the lever to release
from the locking port and then Insert the paper end into
the clamping part, aligning the paper edges even and
parallel with the sides of the base. (Bending the paper
beforehand makes attachment easier). Once the paper is
in place, return the lever to its original position.
Fig.3
Repeat the same process for the other end of the base,
maintaining the proper paper tension.
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
Fig.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.
Installing paper filter bag
Fig.11
Make sure that the logo on the cardboard lip and the logo
on the dust box are on the same side, then install the
paper filter bag by fitting the cardbord lip in the groove of
each holding tab.
Fig.12
Make sure that the logo on the cardboard lip and the logo
on the dust nozzle are on the same side, then install the
dust nozzle on the dust box.
Removing dust box and paper filter bag.
Fig.13
Remove the dust nozzle by pushing the two latches.
Fig.14
Remove the paper filter bag first by pinching the logo
side of its cardboard lip, then by pulling the cardboard lip
downwards to move it out of the holding tab of the dust
box.
OPERATION

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.
