APPLICATIONS
Finish polishing of woodwork surfaces
Sanding surfaces of woodwork or sheet metal prior
to painting, etc.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized con-
forms to the power requirements specified on the
product nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, inviting a serious
accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Installing the sanding paper
(1) Removing the dust cover: (FS10SB)
While slightly opening the dust cover front, raise
the dust cover front as shown in Fig. 1. Disengage
the dust cover rear from the body as shown in Fig.
2. The dust cover is removed.
(2) Mounting the sanding paper:
Insert the sanding paper while unfastening the spring
as shown in Fig. 3. Align the sanding paper in
parallel with the pad and pull it tight.
Should the sanding paper be loosely mounted, the
finishing will become uneven or the sanding paper
may be damaged.
(to facilitate mounting the sanding paper)
After engaging the one side of sanding paper, fold
the other side 10 mm from the edge as shown in
Fig. 4.
Fold the sanding paper again 10 mm from the
folded edge.
(3) Installing the dust cover: (FS10SB)
Position the dust cover as shown in Fig. 5. Engage
the dust cover rear as shown in Fig. 6 and depress
the dust cover front downward.
(4) Installing the cleaner: (FS10SB)
Connect the suction hose to the dust cover hole.
(If the suction hose cannot be connected, attach the
supplied adaptor and fix with tape).
PRACTICAL OPERATING PROCEDURES
CAUTION
Never apply water or grinding fluid when sanding. This
could result in electrical shock.
1. Switching the sander ON and OFF
By pulling the trigger and pushing the stopper, the
switch will remain ON even when the trigger is
released, promoting continuous, efficient operation.
By pulling the trigger again, the stopper is released
and the switch is turned OFF.
CAUTION
Never turn the power switch ON when the sander
is contacting the surface to be sanded. This is
necessary to preclude damage to the material. The
same applies when switching the power OFF.
2. How to hold the orbital sander
While gripping the knob with one hand and the
handle with the other, lightly press the sander against
the surface to be sanded so that the sanding paper
uniformly contacts the surface. DO NOT apply
excessive pressure to the sander while sanding.
Excessive pressure may cause overload of the motor,
reduced service life of the sanding paper, and lower
sanding or polishing efficiency. Also, while sanding
or polishing, never cover the ventilation port on the
upper motor housing. This could cause overheating
and subsequent damage to the tool.
3. How to move the orbital sander
For optimum operating efficiency, alternately move
the sander forward and backward at a constant
speed and balance.
4. After installing new sanding paper
Movement of the sander may tend to become
unsteady after new sanding paper has been in-
stalled, because of the new, coarse grain of the
paper. This can be avoided by slightly tilting the
sander forward or backward during sanding or
polishing. Sander movement will become steady as
the sanding paper surface becomes properly
abraded.

MAINTENANCE AND INSPECTION

1. Inspecting the sanding paper
Since use of worn-out sanding paper will degrade
efficiency and cause possible damage to the pad,
replace the sanding paper as soon as excessive
abrasion is noted.
2. Inspecting the mounting screws:
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Fail-
ure to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Servicing
Consult an authorized Service Center in the event
of power tool failure.
