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
The power can be turned on by setting the lever to
ON (1) and turned off by setting the lever to OFF (0).
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 random orbit sander
While gripping the housing, lightly press the sander
against the surface to be sanded so that the sanding
paper uniformly contacts the surface, as shown in
Fig. 4. 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 lowered sanding or polishing
efficiency.
3. How to move the random orbit sander
Move the sander by either moving it up and down
or by moving it in circles while gradually progress-
ing in a sideways direction (Figs. 5 and 6).
4. After installing new sanding paper
Movement of the sander may tend to become
unsteady after new sanding paper has been installed,
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.
MOUNTING THE OPTIONAL ACCESSORIES
䡬 Mounting the polyester buff
Since the attachment is a hook-and-loop type as
with the sanding paper, the polyester buff can be
mounted by just pressing it onto the pad (Fig. 7).
MAINTENANCE AND INSPECTION
1. Empting and cleaning the Dust Bag
If the dust bag contains too much saw dust, dust
collection will be affected. Empty the dust bag when
it gets full.
Remove the dust bag, open the fastener, and dispose
of the contents.
2. 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 a excessive
abrasion is noted.
3. 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. Failure
to do so could result in serious hazard.
4. 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.
5. Servicing
Consult an authorized Service Agent in the event of
power tool failure.
6. Service parts list
A: Item No.
B: Code No.
C: No. Used
D: Remarks
CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by an Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
By adjusting the dial, match the speed to the material and type of work.
