Care And Maintenance - Hilti WSC 70-A36 Manual De Instrucciones

CAUTION
Wherever possible, use a suitable mobile vacuum
dust removal system such as the WVC 40‑M (wood)
or VCU 40‑M (wood and mineral materials) for the
application concerned. Use a respiratory protector of
the P2 filter class with half-mask facepiece if no dust
removal system is available or its use is impossible.
In addition, to keep the concentration of dust low,
always ensure good ventilation.

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 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.
8.4 Care of the Li-ion battery
Avoid entrance of moisture.
CAUTION
Commercial and industrial users must consult the re-
sponsible trade association to clarify the situation re-
garding special requirements applicable to working on
other materials.
7.12 Using the saw without a dust and chip
removal system 10
NOTE
The power tool can also be used with a push-on chip
deflector.
Turn the nozzle to the desired direction of ejection so that
the chips and dust are deflected away from you.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging
the battery as soon as a significant drop in performance
is noticed.
NOTE
If use of the power tool continues, further battery dis-
charge will be stopped automatically before the battery
cells suffer damage.
Charge the battery with the Hilti charger approved 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. Avoid charging the battery
in places subject to high ambient temperatures (e.g. at
a window) as this 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 possible to continue working with a battery in this
condition but it should be replaced in good time.
8.5 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.
