• 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 a fire.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac
-
cidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
• Do not use a battery pack or tool that is dam
-
aged or modified.
Damaged or modified batteries
may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
• Do not expose a battery pack or tool to fire or
excessive temperature.
Exposure to fire or tem
-
perature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions.
Charging
improperly or at temperatures outside the specified
range may damage the battery and increase the risk
of fire.
SERVICE
• Have your power tool serviced by a qualified
repair person using only identical replacement
parts.
This will ensure that the safety of the power
tool is maintained.
• Never service damaged battery packs.
Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
CIRCULAR SAWS
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 the workpiece in your hands or across
your leg while cutting. 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 sur
-
faces when performing an operation where the
cutting tool may contact hidden wiring.
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 off-center, 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.
Further safety instructions for all saws
Kickback causes and related warnings
- 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 reac-
tion 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. Posi
-
tion 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 con
-
trolled 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 binds,
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, the 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.
• The 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.
