Battery tool use and care
1. Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another battery pack.
2. Use power tools only with specifically designated
battery packs.
Use of any other battery packs may
create a risk of injury and fire.
3. 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.
4. Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
5. Do not use a battery pack or tool that is damaged
or modified.
Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire,
explosion or risk of injury.
6. Do not expose a battery pack or tool to fire or
excessive temperature.
Exposure to fire or
temperature above 130 °C may cause explosion.
7. 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
1. 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.
2. Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.
3. Follow instruction for lubricating and changing
accessories.
CORDLESS CIRCULAR SAW
SAFETY WARNINGS
GEB151-1
Cutting procedures
1. 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.
2. Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the
workpiece.
3. 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.
4. 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 minimise body exposure, blade binding, or
loss of control.
(Fig. 2)
5. Hold the power tool by insulated gripping
surfaces, when performing an operation where the
cutting tool may contact hidden wiring or its own
cord.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
6. When ripping, always use a rip fence or straight
edge guide.
This improves the accuracy of cut and
reduces the chance of blade binding.
7. 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-centre, causing loss of control.
8. 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.
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 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.
1.
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.
2. 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.
3. 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 as the
saw is restarted.
4. 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.
(Fig. 3 & 4)
5. Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
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 cause
binding and kickback.
