Care And Maintenance - Hilti WSC 7.25-A36 Mode D'emploi

8 Care and maintenance

CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
8.3 Cleaning the safety devices
1. Remove the saw blade before cleaning the safety
devices.
2. Clean the safety devices carefully with a dry brush.
3. Use a suitable tool to remove deposits or wood
chips from the inside surfaces of the safety devices.
4. Fit the saw blade.
8.4 Care of the NiCd battery
Avoid entrance of moisture.
Keep the electrical contacts free from dust, oil and
grease. If necessary, use a clean cloth to clean the con-
tact surfaces. The battery must be recharged as soon as
the power tool's performance drops noticeably or when
the deep discharge prevention system becomes active.
NOTE
Please refer to the operating instructions for the charger
for further information about charging the battery.
8.5 Care of the Li-ion battery
Avoid ingress of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharg-
ing the battery as soon as a significant drop in battery
performance is noticed.
NOTE
If use continues, further battery discharge will be stopped
automatically before the battery cells suffer damage.
Charge the battery using an approved charger from Hilti
designed for use with Li-ion batteries.
NOTE
- A conditioning charge (as is required with NiCd or
NiMH batteries) is not necessary.
- Interruption of the charging procedure has no negative
effect on battery life.
- Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as
with NiCd or NiMH batteries).
- For best results, batteries should be stored fully
charged in a cool dry place. Storing the battery in
places subject to high ambient temperatures (e.g. at
a window) has an adverse effect on battery life and
increases the rate of self-discharge.
- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is still possible to work with this battery. You should,
however, soon replace the battery with a new one.
8.6 Maintenance
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the power tool if parts are
damaged or when the controls do not function faultlessly.
Have the power tool repaired by Hilti Service.
8.7 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.
To check the pivoting guard, open the guard fully by
moving the guard operating lever.
The pivoting guard must close quickly and completely
when the guard operating lever is released.
