Using The Saw Without A Dust And Chip Removal System; Care And Maintenance - Hilti SCW22-A Manual De Instrucciones

7.7.3 Longitudinal cuts at up to 50 °
Guide the saw so that the outer edge of the guide rail
adapter runs along the rib on the guide rail. The saw
blade will otherwise come into contact with the guide rail.
7.7.4 Cuts at an angle across the surface of the
workpiece
NOTE
en
The cutting angle indicated is the angle of deviation from
a straight, right-angled cut.
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.
7.8 Using the saw with a dust and chip removal
system 9
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. In order to
connect the vacuum cleaner hose to the saw, use of a
suitable adapter may be necessary.
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

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

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-
piratory 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 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.
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.
