Hitachi C 18DSL Handling Instructions Manual page 54

English
(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. 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. 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.
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.

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
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 a 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.
MODIFICATION
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts (i.e. code numbers and/or
design) may be changed without prior notice.
NOTE
Due to HITACHI's continuing program of research and
development, the specifications herein are subject to
change without prior notice.
Information concerning airborne noise and vibration
The measured values were determined according to
EN60745 and declared in accordance with ISO 4871.
Measured A-weighted sound power level: 103 dB (A)
Measured A-weighted sound pressure level: 92 dB (A)
Uncertainty KpA: 3 dB (A).
Wear hearing protection.
Vibration total values (triax vector sum) determined
according to EN60745.
Cutting chipboard:
Vibration emission value
2
Uncertainty K = 1.5 m/s
The declared vibration total value has been measured in
accordance with a standard test method and may be
used for comparing one tool with another.
It may also be used in a preliminary assessment of
exposure.
WARNING
The vibration emission during actual use of the
power tool can differ from the declared total value
depending on the ways in which the tool is used.
Identify safety measures to protect the operator that
are based on an estimation of exposure in the
actual conditions of use (taking account of all parts
of the operating cycle such as the times when the
tool is switched off and when it is running idle in
addition to the trigger time).
