*1 Dust removal
When an excessive amount of dust is deposited in the
dust bag, dust-collecting e ffi ciency will sharply drop.
Remove dust from the bag when it is deposited up to
about 2/3 the bag capacity, where by dust collecting
e ffi ciency (as well as working e ffi ciency) will be ensured.
Remove dust from the bag as follows:
(1) Loosen the support bar and remove the dust bag.
(Fig. 4)
(2) The bag inlet can be opened by unzipping the slide
fastener.
How to select proper sanding belt
Choose sanding belt of proper grain size and grain type for
your speci fi c purpose, by referring to Table 1 and 2 below.
Table 1
Derived fi nish Proper grain size
Coarse fi nish 30 – 40
Medium fi nish 40 – 100
Semi fi ne fi nish 80 – 240
Fine fi nish 180 – 400
Table 2
Grain type Surface to be worked on
AA Steel, Wood
WA Wood, Bamboo
CAUTION
○ For grain sizes, refer to Table 1
○ Sanding belt grain should be coarser than sandpaper
used for manual work.
○ Use sanding belt of same grain size until uniform
surface is obtained. Changing grain sizes may result in
poor fi nish.
MAINTENANCE AND INSPECTION
1. Inspecting the sanding belt
Since continued use of a worn-out sanding belt will
degrade e ffi ciency, replace the sanding belt 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. Failure 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. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.
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.
