20. Check damaged parts
Before further use of the tool, a guard or other
part that is damaged should be carefully checked
to determine that it will operate properly and per-
form its intended function. Check for alignment of
moving parts, binding of moving parts, breakage
of parts, mounting, and any other conditions that
may affect its operation. A guard or other part
that is damaged should be properly repaired or
replaced by an authorized service centre unless

relevant safety rules. Repairing of electric appli-
ances may be carried out only by experts other-
wise it may cause considerable danger for the user.

ADDITIONAL SAFETY RULES

1. Hold tools by insulated gripping surfaces
when performing an operation where the cut-
ting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and
shock the operator.
2. Hold the tool firmly with both hands.
3. Make sure the belt is not contacting the work-
piece before the switch is turned on.
4. Keep hands away from rotating parts.
5. Do not leave the tool running. Operate the
tool only when hand-held.
6. This tool has not been waterproofed, so do
not use water on the workpiece surface.
SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS
Installing or removing abrasive belt (Fig. 1)
Important:
Always be sure that the tool is switched off and uol-
nplugged before installing or removing the belt.
Pull the lever all the way out and install the belt over
the rollers, then return the lever to the original posi-
tion.
CAUTION:
When installing the belt, make sure that the direction
of the arrow on the back of the belt corresponds to
the one on the tool itself. (Fig. 2)
Adjusting belt tracking (Fig. 3)
Switch on the tool and make sure that the belt is
aligned properly. If the edge of the belt extends
beyond the edge of the base or the edge of the belt
retracts more than 6 mm away from the edge of the
base, use the adjusting knob to adjust the belt track-
ing.
Dust bag (Fig. 4 & 5)
Attach the dust bag onto the dust spout. The dust
spout is tapered. When attaching the dust bag, push
it onto the dust spout firmly as far as it will go to pre-
vent it from coming off during operation. For the best
results, empty the dust bag when it becomes about
half full, tapping it lightly to remove as much dust as
possible.
Switch action (Fig. 6)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
• The tool should not be in contact with the workpiece
surface when you turn the tool on or off. Otherwise a
poor sanding finish or damage of the belt may result.
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. 7)
For 9903, 9920 and 9404
The belt speed can be infinitely adjusted between
210 m and 440 m per minute by turning the speed
adjusting dial to a given number setting from 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. Select
the proper speed for the workpiece to be sanded.
CAUTION:
The speed adjusting dial can be turned only as far as
5 and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.
