WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745
and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications,
with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories,
keep the hands warm, organisation of work patterns.
WARNING! Read all safety warnings and all instructions,
including those given in the accompanying brochure. Failure
to follow the warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

SAFETY INSTRUCTIONS

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 power tool by insulated gripping surfaces, when
performing an operation where the cutting tool may contact
hidden wiring. Cutting accessory contacting a „live" wire may
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.
Causes and operator prevention of kickback:
- 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
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 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 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 making a "plunge cut" into existing
walls or other blind areas. The protruding blade may cut objects
that can cause kickback.
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.
Do not use saw blades not corresponding to the key data given in
these instructions for use.
The dust produced when using this tool may be harmful to health.
Do not inhale the dust. Wear a suitable dust protection mask.
Always wear ear protectors. Exposure to noise can cause
hearing loss.
