Maintenance And Inspection - Hitachi c 18dsl Handling Instructions Manual

(2) Push the back of the socket, and remove the socket
and the light bulb together from the handle cover
(Fig. 24).
(3) Remove the light bulb from the socket (Fig. 25).
2. Attaching light bulb
Take procedures here that are contrary to the
detaching procedures.
NOTE
When attaching the light bulb to the socket, insert
the light bulb until it lightly bumps against the
socket.
When attaching the socket to the handle cover,
align the socket with the hole of housing while
watching the back of the socket shown in Fig. 25,
and insert the socket until it lightly bumps against
the handle cover.

MAINTENANCE AND INSPECTION

CAUTION
Pull out battery before doing any inspection or
maintenance.
1. Inspecting the saw blade
Since use of a dull saw blade will degrade efficiency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as abrasion is noted.
CAUTION
If a dull saw blade is used, reactive force is increased
during cutting operation. Avoid the use of the dull
saw blade without repair.
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. Performance checkup and maintenance of lower
guard
Keep the lower guard in good shape for smooth
performance at all times. Be sure to make prompt
repair in case of any malfunction.
For safe and proper working, always keep the
machine and ventilation slots clean. The lower guard
must always be able to more freely and retract
automatically. Therefore, always keep the area
around the lower guard clean. Remove dust and
chips by blowing out with compressed air or with
a brush.
5. Adjusting the base and saw blade to maintain
perpendicularity
The angle between the base and the saw blade has
been adjusted to 90°, however should this
perpendicularity be lost for some reason, adjust in
the following manner:
(1) Turn the base face up (Fig. 26) and loosen the wing-
bolt.
(2) Apply a square to the base and the saw blade and
turning the slotted set screw with a slotted-head
screwdriver, shift the position of the base to produce
the desired right angle.
6. Check for dust
Dust may be removed with a clean rag or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.
7. Storage
Storing in a place below 40°C and out of the reach
of children.
NOTE
Make sure that the battery is fully charged when
stored for a long period (3 months or more). The
battery with smaller capacity may not be able to
be charged when used, if stored for a long period.
NOTE
Storing lithium-ion batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge
may result in performance deterioration, significantly
reducing battery usage time or rendering the
batteries incapable of holding a charge.
However, significantly reduced battery usage time
may be recovered by repeatedly charging and using
the batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries
dead and purchase new batteries.
8. Service and repairs
All quality power tools will eventually require
servicing or replacement of parts because of wear
from normal use. To assure that only genuine
replacement parts must be used, all service and
repairs must be performed by a HITACHI
AUTHORIZED SERVICE CENTER, ONLY.
9. Service parts list
