Cordless Metal Cutter safety warnings
Cutting procedures
1 . DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on auxil-
iary handle, or motor housing. I f bot h h an d s are
holding the saw, they cannot be cut by the blade.
2. Do not reach underneath the workpiece. T h e
guard cannot protect you from the blade below the
w orkpie c e.
3. Adjust the cutting depth to the thickness of
the workpiece. L ess t h an a f ull toot h o f t h e bla d e

4 . Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform. I t is important to
support the work properly to minimise body expo-
sure, bla d e bin d ing, or loss o f c ontrol.
5 . Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring.

Kickback is the result of saw misuse and/or incorrect
operating pro c e d ures or c on d itions an d c an be a v oi d e d
by taking proper precautions as given below.
Maintain a firm grip with both hands on the
1 .
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,
i f proper pre c autions are taken.
2. W hen 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. I nv estigate and take c orrec -
tiv e ac tions to eliminate th e c ause of blad e bind ing.
3. W hen restarting a saw in the workpiece, centre
the saw blade in the kerf so that the saw teeth
are not engaged into the material. I f a sa w bla d e
binds, it may walk up or kickback from the work-
pie c e as t h e sa w is restarte d .
4 . Support large panels to minimise the risk of
blade pinching and kickback. L arge panels ten d
to sag un d er t h eir o w n w eig h t. S upports must be
pla c e d un d er t h e panel on bot h si d es, near t h e line
o f c ut an d near t h e e d ge o f t h e panel.
5 . Do not use dull or damaged blades. U nsh arpened
or improperly set blades produce narrow kerf causing
ex c essiv e f ric tion, blad e bind ing and kic kbac k.
6 . Blade depth and bevel adjusting locking levers
must be tight and secure before making the
cut. If blade adjustment shifts while cutting, it may
c ause bin d ing an d ki c kba c k.
7. Use extra caution when sawing into existing
walls or other blind areas. T h e protru d ing bla d e
may cut objects that can cause kickback.
ALWAYS hold the tool firmly with both hands.
8 .
NEVER place your hand, leg or any part of your
body under the tool base or behind the saw,
especially when making cross-cuts. I f ki c kba c k
occurs, the saw could easily jump backwards over
your hand, leading to serious personal injury.
9 . Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
F or c ing t h e sa w c an c ause une v en c uts, loss o f
accuracy, and possible kickback.
Lower guard function
1 . 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. R aise th e low er guard w ith th e retrac ting h and le
and make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
2. Check the operation of the lower guard spring. If
the guard and the spring are not operating prop-
erly, they must be serviced before use. L o w er
guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
3. 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. F or all ot h er sa w ing, t h e lo w er
guard should operate automatically.
4 . Always observe that the lower guard is cover-
ing the blade before placing the saw down on
bench or oor. A n unprote c te d , c oasting bla d e
