Care And Maintenance - Hilti SCM 22-A Operating Instructions Manual

CAUTION
Empty the chip collector and clean the power tool
before putting it away in the toolbox or other container
for storage or transport. Metal chips may otherwise fall
out of the collector and find their way into the power
tool, battery or charger, presenting a risk of damage or
malfunction.
When the power tool is in use you can check with the aid
of the viewing window whether the collector is full.
1. Remove the battery from the tool.
2. Pull the chip collector away from the tool to the rear.

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 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 dischar-
ging 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.
3. Swing the two halves of the chip collector apart and
empty out its contents.
4. Push the chip collector onto the guard until in en-
gages in position.
7.7 Procedure if the chip / dust channel is blocked
1. Remove the battery from the tool.
2. Remove the chip collector.
3. Clean the chip / dust channel.
4. Check that moving parts on the power tool are work-
ing properly and not jamming. Check also whether
parts are broken or damaged in such a way that
may cause the power tool to malfunction.
- 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.
8.4 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.
8.5 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.
8.6 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.
