– 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.
Maintain a firm grip with both hands on the saw and posi-
tion 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.
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.
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.
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.
Do not use dull or damaged blades. Unsharpened or improper-
ly set blades produce narrow kerf causing excessive friction, blade
binding and kickback.
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.
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
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.
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.
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.
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.
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.
Appliances used at many different locations including open air
should be connected via a residual current device (FI, RCD, PRCD) of
30mA or less.
Before doing any work on the machine, pull the plug out of the
socket.
Only plug-in when machine is switched off.
Do not use saw blades not corresponding to the key data given in
these instructions for use.
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.
Do not fix the on/off switch in the „on“ position when using the saw
hand-held.
Please do not use abrasion disks in this machine!
Adapt the feed speed to avoid overheating the blade tips.
