Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of the
workpiece toward the operator;
– when the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit
rapidly back toward the operator;
– if the blade becomes twisted or misaligned in the cut, the teeth
at the back edge of the blade can dig into the top surface of the
wood causing the blade to climb out of the kerf and jump back
toward the operator.
Kickback is the result of saw misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below.
a) Maintain a firm grip with both hands on the saw and
position your arms to resist kickback forces. Position your
body to either side of the blade, but not in line with the
blade. Kickback could cause the saw to jump backwards, but kick-
back forces can be controlled by the operator, if proper precautions
are taken.

b) When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to a
complete stop. Never attempt to remove the saw from the
work or pull the saw backward while the blade is in motion
or kickback may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre the saw
blade in the kerf and check that saw teeth are not engaged
into the material. If saw blade is binding, it may walk up or
kickback from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag under their own
weight. Supports must be placed under the panel on both sides,
near the line of cut and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened or im-
properly set blades produce narrow kerf causing excessive friction,
blade binding and kickback.
f) Blade depth and bevel adjusting locking levers must be
tight and secure before making cut. If blade adjustment shifts
while cutting, it may cause binding and kickback.
g) Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects that can
cause kickback.

Lower guard function
a) Check lower guard for proper closing before each use. Do not
operate the saw if lower guard does not move freely and close
instantly. Never clamp or tie the lower guard into the open
position. If saw is accidentally dropped, lower guard may be bent.
Raise the lower guard with the retracting handle and make sure it
moves freely and does not touch the blade or any other part, in all
angles and depths of cut.
b) Check the operation of the lower guard spring. If the
guard and the spring are not operating properly, they must
be serviced before use. Lower guard may operate sluggishly due
to damaged parts, gummy deposits, or a build-up of debris.
c) Lower guard may be retracted manually only for special
cuts such as „plunge cuts" and „compound cuts". Raise
lower guard by retracting handle and as soon as blade enters the
material, the lower guard must be released. For all other sawing,
the lower guard should operate automatically.
d) Always observe that the lower 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.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS:
Wear ear protectors. Exposure to noise can cause hearing loss.
Always wear goggles when using the machine. It is recommended
to wear gloves, sturdy non slipping shoes and apron.
The dust produced when using this tool may be harmful to health.
Do not inhale the dust. Use a dust absorption system and wear a
suitable dust protection mask. Remove deposited dust thoroughly,
e.g. with a vacuum cleaner.
Do not use saw blades not corresponding to the key data given in
these instructions for use.
Do not use abrasion disks in this machine!
Do not fix the on/off switch in the „on" position when using the saw
hand-held.

WORKING INSTRUCTIONS

Adapt the feed speed to avoid overheating the blade tips.

MAINS CONNECTION

Connect only to single-phase AC system voltage as indicated on
the rating plate. It is also possible to connect to sockets without an
earthing contact as the design conforms to safety class II.
Appliances used at many different locations including wet room
and open air must be connected via a residual current device (FI,
RCD, PRCD) of 30mA or less.
Make sure the machine is switched off before plugging in.
Do not let any metal parts enter the airing slots - danger of short
circuit!
Keep mains lead clear from working range of the machine. Always
lead the cable away behind you.
Before use check machine, cable, and plug for any damages or
material fatigue. Repairs should only be carried out by authorised
Service Agents.
