– when the blade is pinched or jammed 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 proce-
dures 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 po-
sition 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 kickback 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 so that the saw teeth are not engaged into
the material. If the saw blade binds, it may lift up the workpiece and
cause kickback when 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 impro-
perly 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 the 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 the lower guard for proper closing before each use.
Do not operate the saw if the lower guard does not move
freely and close instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally dropped, the
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) The lower guard may be retracted manually only for
special cuts such as „plunge cuts“ and „compound cuts“. Raise
the lower guard by the retracting handle and as soon as the
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 the 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.
WORKING INSTRUCTIONS
Adapt the feed speed to avoid overheating the blade tips.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Wear ear protectors. Exposure to noise can cause hearing loss.
Use protective equipment. Always wear safety glasses when working
with the machine. The use of protective clothing is recommended,
such as dust mask, protective gloves, sturdy non-slip footwear,
helmet and ear defenders.
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.
It is necessary to select a saw blade which is suitable for the material
being cut.
Use only woodworking blades specified in this manual, which comply
with EN 847-1.
The rated speed of the accessory must be at least equal to the
maximum speed marked on the power tool.
Do not use abrasion discs in this machine!
Do not fix the on/off switch in the „on“ position when using the saw
hand-held.
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.
Only plug-in when machine is switched off.
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, safety harness and plug for any
damages or material fatigue. Repairs should only be carried out by
authorised Service Agents.
A power spike causes voltage fluctuations and may affect other
electrical products in the same power line. Connect the product to a
power supply with an impedance equal to 0.3 Ω to minimize voltage
fluctuations.
Contact your electric power supplier for further clarification.
