— 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
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 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
4
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.
SAFETY INSTRUCTIONS FOR
SAWS WITH INNER PENDULUM
GUARD
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
20V Cordless Brushless Circular saw
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
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.
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 RULES
FOR YOUR CIRCULAR SAW
1.
Only use saw blades recommended in the specification.
2.
Do not use any abrasive wheels.
3.
Use only blade diameter(s) in accordance with the
markings.
4.
Identify the correct saw blade to be used for the
material to be cut.
5.
Use only saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
SAFETY WARNINGS FOR
BATTERY PACK
a)
Do not dismantle, open or shred battery pack.
b) Do not expose battery pack to heat or fire.
Avoid storage in direct sunlight.
c)
Do not short-circuit a battery pack. Do not store
battery packs haphazardly in a box or drawer
where they may short-circuit each other or be
short-circuited by other metal objects. When
battery pack is not in use, keep it away from other
metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or fire.
d) Do not remove battery pack from its original
packaging until required for use.
e)
Do not subject battery pack to mechanical shock.
f)
In the event of battery leaking, do not allow the
liquid to come in contact with the skin or eyes.
If contact has been made, wash the affected
area with copious amounts of water and seek
medical advice.
g) Observe the plus (+) and minus (–) marks on
the battery back and equipment and ensure
