ADDITIONAL SAFETY WARNINGS
GENERAL
• This tool should not be used by people under the age of
16 years
• This tool is not suitable for wet cutting
• Do not work materials containing asbestos (asbestos
is considered carcinogenic)
• Dust from material such as paint containing lead, some
wood species, minerals and metal may be harmful
(contact with or inhalation of the dust may cause allergic
reactions and/or respiratory diseases to the operator or
bystanders); wear a dust mask and work with a dust
extraction device when connectable
• Certain kinds of dust are classified as carcinogenic
(such as oak and beech dust) especially in conjunction
with additives for wood conditioning; wear a dust
mask and work with a dust extraction device when
connectable
• Follow the dust-related national requirements for the
materials you want to work with
• Do not use this saw in combination with a saw table
• Remove battery from tool before making any adjustments
or changing accessories
ACCESSORIES
• SKIL can assure flawless functioning of the tool only
when original accessories are used
• Use only saw blades that correspond with the
characteristic data given in these operation instructions
and that are tested and marked in accordance with EN
847-1
• Use only accessories with an allowable speed matching
at least the highest no-load speed of the tool
• Use only saw blades with a minimum diameter of 140
mm, a maximum diameter of 140 mm and a spindle hole
of 10 mm
• Never use saw blades made of high speed steel (HSS)
• Never use grinding/cutting discs with this tool
BEFORE USE
• Avoid damage that can be caused by screws, nails and
other elements in your workpiece; remove them before
you start working
• Remove all obstacles on top of as well as underneath the
cutting path before you start cutting
• Secure the workpiece (a workpiece clamped with
clamping devices or in a vice is held more securely than
by hand)
• Use suitable detectors to find hidden utility lines
or call the local utility company for assistance
(contact with electric lines can lead to fire or electrical
shock; damaging a gas line can result in an explosion;
penetrating a water pipe will cause property damage or
an electrical shock)
DURING USE
• The noise level when working can exceed 85 dB(A); wear
ear protection
• Never use the tool without the original protection guard
system
• Do not attempt to cut extremely small workpieces
• Do not work overhead with the tool
• In case of jamming or electrical or mechanical
malfunction, immediately switch off the tool and
disconnect the plug
AFTER USE
• When you put away the tool, switch off the motor and
ensure that all moving parts have come to a complete
standstill
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 kickback 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 backwards while the
blade is in motion or kickback may occur. Investigate
and take corrective actions to eliminate the cause of
blade binding. Avoid cutting nails or screws.
c) 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.
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 improperly 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.
3) LOWER GUARD FUNCTION
a) 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 the 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.
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) Lower guard should 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.
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.
