ADDITIONAL SAFETY
INSTRUCTIONS FOR PLUNGE
SAWS
Make sure that the mains voltage matches the
specifications on the type plate.
Persons with restricted physical, sensory or
mental capabilities are not allowed to use the
plunge saw unless they are supervised and
instructed by a guardian.
Never leave the powered-on saw unattended
and keep them out of reach of children and
persons in need of supervision.
Do not bring your hands in the cutting area and
the saw blade.
Keep in mind that even a worn saw blade is still
very sharp. Always grasp the saw blade
on the sides. Do not fling the saw blade and do not
drop it.
Never use the plunge saw with grinding
wheels.
Do not grip underneath the workpiece. The
protective cover cannot protect you from the
saw blade under the workpiece.
Adjust the cutting depth to the thickness of the
workpiece. It should be visible less than a
full tooth height under the workpiece.
Do not cut very small workpieces. When cutting
round wood, use a device which secures
the workpiece from twisting. Never hold the
workpiece to be cut in your hand or across
your leg. It is important to secure the workpiece
properly to minimise the risk of physical
contact, jamming of the saw blade or loss of control.
Hold the saw only by the insulated gripping
surfaces when performing an operation
where the cutting tool may come into contact with
hidden power lines or its own device
cable. Contact with a live wire also exposes the
metal parts to tension and leads to an
electric shock.
Use always saw blades in the correct size and
with suitable locating bore. Saw blades that
do not match the mounting parts of the saw will run
unevenly and lead to loss of control.
Never use a damaged or incorrect outer flange
or a damaged clamping screw. The outer
flange and the clamping screw have been specially
designed for your saw for optimum
performance and reliability.
Start the plunge saw and begin cutting when it
reaches the full idling speed.
Never brake the saw blade using lateral
pressure after switching it off.
Set the saw aside only when the saw blade
comes to a standstill.
Do not expose the saw to high temperatures,
humidity and strong shocks. The saw can be
damaged as a result.
Hold the saw firmly with both hands and bring
your arms into a position in which you can
resist the kickback forces.
When ripping always use a rip fence or straight
edge guide. This improves the accuracy of
cut and recuses chance of blade binding.
Never use damaged or incorrect blade washers
of bolt. The blade washers and bolt were
specially designed for your saw, for optimum
performance and safety of operation.
Check guard for proper closing before each
use. Do not operate the saw if guard does not
move freely and enclose the blade instantly. Never
clamp or tie the guard with the blade
exposed. If saw is accidently dropped, guard may
be bent. Check to make sure that guard moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
Assure that the guide plate of the saw will not
shift while performing the "plunge cut" when bevel
setting is not at 90°. Blade shift sideways will cause
binding and likely kick back.
Always observe that the guard is covering the
blade before placing saw down on bench or floor.
An unprotected, coasting blade will cause the saw
to walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop
after switch is released.
Do not unnecessarily burden the machine.
Excessive pressure when cutting will damage
the blade quickly. This leads to a reduction in
performance of the machine in the processing and
in the cutting accuracy.
CAUSES AND PREVENTION OF
KICKBACK
A kickback is the sudden reaction as a result of
a stuck, jammed or misaligned saw blade which
leads to an uncontrolled saw to be lifted and moved
from the workpiece out in the direction of the
operator.
A kickback can occur when the saw blade gets
stuck or jammed in the saw gap. The saw blade is
blocked and the motor force repels the circular saw
in the direction of the operator.
A kickback can occur when the saw blade
becomes twisted or misaligned in the saw groove.
As a result, the teeth of the back edge of the saw
blade can get stuck in the surface of the workpiece,
whereby the saw blade is moved out of the saw gap
and the saw jumps back in the direction of the
operator.
A kickback is the result of incorrect or faulty
use of the saw. It can be prevented by appropriate
precautions as described below.
Hold the saw firmly with both hands and bring
your arms into a position in which you can resist the
kickback forces. Always hold the saw blades on the
sides, never bring the blade in line with your body.
In a kickback, the saw can jump backwards, but the
operator can control the kickback forces if
appropriate measures were taken.
If the saw blade jams or sawing is interrupted
for any reason, release the ON / OFF switch
and calmly hold the saw in the material until the saw
blade stands completely still. Never attempt to
