Maintenance And Inspection; Modifications - Hitachi P18DSL Bedienungsanleitung

4. Grinding Stone
When a water grinding stone is available, use it after
dipping it suffi ciently in water since such a grinding
stone may be worn during grinding procedures, fl atten
the upper surface of the grinding stone as frequently as
possible.
ATTACHING AND DETACHING THE DUST
ADAPTER (OPTIONAL ACCESSORY)
CAUTION
○ To prevent accidents, ensure that the power tool is
switched off and pull out the battery.
○ Follow the procedure below to mount the dust adapter
securely. Failure to do so may result in the adapter
coming off , causing injury.
1. Attaching the dust adapter
(1) Remove the screw D4 × 16 in the chip cover and remove
the chip cover as shown in Fig. 35.
(2) Mount the dust adapter and secure with the screw D4 ×
16. (Fig. 36)
NOTE
Take care not to break the catch when attaching or
detaching the dust adapter and chip cover.
2. Removing the dust adapter
To remove the dust adapter, follow the procedure above
in reverse order.

MAINTENANCE AND INSPECTION

1. Inspecting the blades
Continued use of dull or damaged blades will result in
reduced cutting effi ciency and may cause overloading
of the motor. Sharpen or replace the blades as often as
necessary.
2. Handling
CAUTION
The front base, rear base, and cutting depth control
knob are precisely machined to obtain specifi cally high
precision. If these parts are roughly handled or subjected
to heavy mechanical impact, it may cause deteriorated
precision and reduced cutting performance. These parts
must be handled with particular care.
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. Inspecting the carbon brushes (Fig. 37)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or near
the "wear limit". In addition, always keep carbon brushes
clean and ensure that they slide freely whthin the brush
holders.
NOTE
When replacing the carbon brush with a new one, be sure
to use the Hitachi Carbon Brush Code No. 999017.
5. Replacing carbon brushes
After removing the chip cover, take out the carbon brush
by fi rst removing the brush cap and then hooking the
protrusion of the carbon brush with a slotted head screw
driver, etc., as shown in Fig. 38.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush agrees with the
contact portion outside the brush tube. Then push it in
with a fi nger as illustrated in Fig. 39. Lastly, install the
brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon brush
into the contact portion outside the brush tube.
(You can insert whichever one of the two nails provided.)
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
6. 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.
7. Cleaning on the outside
When the planer is stained, wipe with a soft dry cloth or
a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
8. Storage
Store the planer in a place in which the temperature is
less than 40°C and out of 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, signifi cantly reducing
battery usage time or rendering the batteries incapable of
holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
9. Service parts list
CAUTION
Repair, modifi cation 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.

MODIFICATIONS

Hitachi Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without prior
notice.
