used.
For the riving knife to work, it must be thicker
than the body of the blade but thinner than the tooth
set of the blade.
b)
Adjust the riving knife as described in this instruc-
tion manual.
Incorrect spacing, positioning and align-
ment can make the riving knife ineffective in pre-
venting kickback.
c)
Always use the riving knife except when plunge cut-
ting.
Riving knife must be replaced after plunge cut-
ting. Riving knife causes interference during plunge
cutting and can create kickback.
d)
For the riving knife to work, it must be engaged in
the workpiece.
The riving knife is ineffective in pre-
venting kickback during short cuts.
e)
Do not operate the saw if riving knife is bent.
Even
a light interference can slow the closing rate of a guard.
4.2 Additional safety precautions
4.2.1 Personal safety
a)
Wear ear protection.
Excessive noise may lead to a
loss of hearing.
b)
Use the auxiliary handle supplied with the tool.
Loss of control of the tool may lead to injury.
c)
Always hold the tool securely with both hands on
the grips provided. Keep the grips clean, dry and
free from oil and grease.
d)
Breathing protection must be worn when the tool is
used without a dust removal system for work that
creates dust.
e)
To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away tho the rear.
f)
Bring the blade into contact with the workpiece only
after the circular saw has been switched on.
g)
The area above and below the kerf must be free of
obstructions. Do not saw into screws and nails etc.
h)
Do not use the machine for sawing overhead.
i)
Do not attempt to brake the speed of the saw blade
by pressing it to the side.
j)
Do not use:
– cutting discs designed for use with an angle grinder
– hardened steel saw blades (HSS steel)
k)
Do not touch the part of the blade projecting beneath
the workpiece, the clamping flange or the flange
screw.
l)
Never press the spindle lockbutton while the blade
is rotating.
m)
Operate the tool only together with the applicable
protective devices or equipment.
n)
Wear protective gloves when changing insert tools.
The insert tool may become hot during use.
o)
Operate the tool only as directed and only when it
is in faultless condition.
p)
Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
q)
Dust from material such as paint containing lead,
some wood species, minerals and metal may be harm-
ful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the
operator or bystanders. Certain kinds of dust are clas-
sified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood con-
ditioning (chromate, wood preservative). Material
containing asbestos must only be treated by spe-
cialists.
Where the use of a dust extraction device is
possible it shall be used. To achieve a high level of
dust collection, use a suitable vacuum cleaner of
the type recommended by Hilti for wood dust and/or
mineral dust together with this tool. Ensure that the
workplace is well ventilated. The use of a dust mask
of filter class P2 is recommended. Follow national
requirements for the materials you want to work
with.
r)
The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
s)
Children must be instructed not to play with the tool.
4.2.2 Power tool use and care
a)
Secure the workpiece. Use clamps or a vice to hold
the workpiece in place.
The workpiece is thus held
more securely than by hand and both hands remain
free to operate the tool.
b)
Ensure that the insert tools used are equipped with
the appropriate connection end system and that they
are properly fitted and secured in the chuck
.
c)
In the event of a power faillure, switch the tool off
and unplug the supply cord.
This prevents inadver-
tent starting when the power returns.
d)
Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with
a “live” wire will make exposed metal parts of the tool
“live” and shock the operator.
4.2.3 Electrical safety
a)
Before beginning work, check the working area (e.g.
with a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the tool may become live if,
for example, an electric cable is damaged inadvertenly.
This presents a serious risk of electric shock.
b)
Check the condition of the supply cord and its plug
connections and have it replaced by a qualified
electrician if damage is found. Check the condi-
tion of the extension cord and replace it if dam-
age is found. Do not touch the supply in the event
of it suffering damage while working. Disconnect
the supply cord plug from the socket
. Damaged
supply cords and extension cords present a risk of
electric shock.
c)
Use of a fault current protection switch increases
safety at work.
4.2.4 Work area
a)
Ensure that the workplace is well lit.
