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 a saw blade binds, 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 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. NOTE Alternate wording for "retracting handle" is
possible.
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 recom-
mended, 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. Wear a suitable dust protection mask.
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.
The rated speed of the accessory must be at least equal to the
maximum speed marked on the power tool.
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.
Adapt the feed speed to avoid overheating the blade tips.
Use only System M18 chargers for charging System M18 battery
packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store only in dry
rooms. Keep dry at all times.
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. Cor-
rosive or conductive fluids, such as seawater, certain industrial
chemicals, and bleach or bleach containing products, etc., Can
cause a short circuit.
ELECTRIC BRAKE
The electric brake engages when the trigger is released, causing
the blade to stop and allowing you to proceed with your work.
Generally, the saw blade stops within 3 seconds.
However, there may be a delay between the time you release the
trigger and when the brake engages. At a power interruption and
still switched on machine, the braking function is not available.
You must always wait for the blade to stop completely before
removing the saw from the workpiece.
SPECIFIED CONDITIONS OF USE
The Metal Saw may be used to cut lenghtways and mitre a variety
of metals, such as metal profiles (UniStrut), pipes, metal studs,
channels, aluminium profiles, metal sheets, etc.
