PRACTICAL OPERATING PROCEDURES

CAUTION
Never apply water or grinding fl uid 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
(I) 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 effi ciency.
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 progressing 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

○ 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 aff ected. 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
effi ciency and cause possible damage to the pad,
replace the sanding paper as soon as 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. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to Hitachi Authorized Service Center for the
cord to be replaced.
6. Servicing
Consult an authorized Service Agent in the event of
power tool failure.
7. Service parts list
A: Item No.
B: Code No.
C: No. Used

CAUTION
Repair, modifi cation 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.
