Care And Maintenance - Hilti SCW 22-A Mode D'emploi

1. Position the guide rail with the zero mark at the edge
of the workpiece and then pivot the rail until the
desired angle shown on the angle scale is opposite
the zero mark.
2. Use the two screw clamps to secure the guide rail.

NOTE
The circular saw is equipped with a removable connector
for a vacuum cleaner / dust removal hose. This connector
is designed to fit standard suction hoses.
CAUTION
Dusts are hazardous to the health and can cause respir-
atory or skin diseases and allergic reactions.
WARNING
Certain dusts are considered to be carcinogenic (cause
cancer). These include mineral dust as well as oak and/or
beech wood dust, particularly in conjunction with addi-
tional substances used for the treatment of wood (chro-
mate, wood preservatives).
CAUTION
As far as possible, use a suitable Hilti sawdust ex-
tractor/deduster, whatever the application. Use a res-

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.

facepiece if no dust removal system is available or its
use is impossible. In addition, to keep the concentra-
tion of dust low, always ensure good ventilation.
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.
7.9 Using the saw without a dust and chip removal
system
The special design of the hose connector prevents block-
age when working without a vacuum cleaner connected.
The sawdust is then guided away to the side.
Check that the sawdust is ejected without obstruction.
If required, the hose connector can be removed from the
blade guard after releasing the hex. socket screw using
the wrench supplied (located on the power tool).
7.10 Procedure when sawdust channel is blocked
1. Pull the battery out of the tool.
2. Clean the sawdust channel.
3. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the power tool's operation.
8.3 Care of the Li-ion battery
Avoid entrance of moisture.
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.
