XI
g) Always use blades with correct size and shape (diamond
versus round) of arbour holes. Blades that do not match the
mounting hardware of the saw will run off-centre, causing loss of
control.
h) Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed for your saw,
for optimum performance and safety of operation.
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, jammed 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 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
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 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 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 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.
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 re-
commended, 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 BS 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 fix the on/off switch in the „on“ position when using the saw
hand-held.
Do not use abrasion discs in this machine!
Remove the battery pack before starting any work on the
appliance.
WARNING! To reduce the risk of fire, personal injury, and product
damage due to a short circuit, never immerse your tool, battery
pack or charger in fluid or allow a fluid to flow inside them.
Corrosive or conductive fluids, such as seawater, certain industrial
chemicals, and bleach or bleach containing products, etc., Can
cause a short circuit.
Never break open battery packs and chargers and store only in dry
rooms. Keep dry at all times.
