Special Safety inStructionS when uSing a Saw
blade
cutting procedures
danger: Keep hands away from cutting area and the
blade. Keep your second hand on auxiliary handle, or motor
housing. If both hands are holding the saw, they cannot be cut by
the blade.
do not reach underneath the workpiece. The guard cannot
protect you from the blade below the workpiece.
adjust the cutting depth to the thickness of the workpiece.
Less than a full tooth of the blade teeth should be visible below the
workpiece.
never hold piece being cut in your hands or across your leg.
Secure the workpiece to a stable platform. It is important to
support the work properly to minimize body exposure, blade binding,
or loss of control.
hold the power tool by insulated gripping surfaces only,
when performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a „live“ wire
will also make exposed metal parts of the power tool „live“ and could
give the operator an electric shock.
when ripping always use a rip fence or straight edge guide.
This improves the accuracy of cut and reduces the chance of blade
binding.
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 eccentrically, causing loss of
control.
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, 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 proce-
dures or conditions and can be avoided by taking proper precautions
as given below.
Maintain a firm grip with both hands on the saw and position
your arms to resist kickback forces. position your body to eit-
her 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 improperly
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 builup 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.
Special Safety inStructionS when uSing a
diaMond cutting wheel
cut-off machine safety warnings
the guard provided with the tool must be securely attached
to the power tool and positioned for maximum safety, so
the least amount of wheel is exposed towards the operator.
position yourself and bystanders away from the plane of the
rotating wheel. The guard helps to protect operator from broken
wheel fragments and accidental contact with wheel.
use only diamond cut-off wheels for your power tool. Just
because an accessory can be attached to your power tool, it does not
assure safe operation.
the rated speed of the accessory must be at least equal to
the maximum speed marked on the power tool. Accessories
running faster than their rated speed can break and fly apart.
wheels must be used only for recommended applications. for
example: do not grind with the side of cut-off wheel. Abrasive
cut-off wheels are intended for peripheral grinding, side forces
applied to these wheels may cause them to shatter.
