POWER TOOL SAFETY WARNINGS
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. DO NOT operate this saw in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools create sparks which may
ignite the dust or fumes.
3. Keep children and bystanders away while operating this saw. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. The saw plug must match the outlet. NEVER modify the plug in any way. DO
NOT use adaptor plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
2. DO NOT expose the saw to rain or wet conditions. Water entering the saw
will increase the risk of electric shock.
3. DO NOT abuse the cable. NEVER use it for carrying, pulling or unplugging
the saw. Keep the cable away from heat, oil, sharp edges or moving parts.
Damaged or entangled cables increase the risk of electric shock.
4. When operating the saw outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
5. If operating the saw in a damp location is unavoidable, use a residual
current device (RCD) protected supply.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when
operating the saw. DO NOT use this saw while you are tired or under the
influence of drugs, alcohol or medication. A moment of inattention while
operating power tools may result in personal injury.
2. Use safety equipment. ALWAYS wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
3. Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying this saw with your finger on the switch or plugging in
invites accidents.
4. Remove any hex key before turning the saw on. A hex key left attached to
a rotating part may result in personal injury.

7

5. DO NOT overreach. Keep proper footing and balance at all times. This
enables better control of the saw in unexpected situations.
6. Dress appropriately, DO NOT wear loose clothing or jewellery. Keep your
hair, clothing and gloves away from moving parts. Loose clothes, jewellery
or long hair can be caught in moving parts.
POWER TOOL USE AND CARE
1. DO NOT force the saw. Use the correct accessories for your application.
The correct power tool will do the job better and safer at the rate which it
was designed for.
2. DO NOT use the saw if the switch does not turn it on and off. Any power tool
that cannot be controlled with the switch is dangerous and SHOULD NOT
be used until it has been repaired.
3. Disconnect the plug from the power source before changing accessories,
or storing the saw. Such preventive safety measures reduce the risk of
starting the saw accidentally.
4. Store idle tools out of the reach of children and DO NOT allow persons
unfamiliar with the saw or these instructions to operate it. Power tools are
dangerous in the hands of untrained users.
5. Check for misalignment or binding of moving parts, breakage of parts and
any other condition that may affect the saw’s operation. If damaged,
have the saw repaired before use. Many accidents are caused by poorly
maintained power tools.
6. Use the saw and accessories in accordance with these instructions and in
the manner intended, taking into account the working conditions and the
work to be performed. Use of the saw for operations different from
intended could result in a hazardous situation.
7. The performance of this saw may vary, depending upon variations in line
voltage. Extension cable usage may also affect performance.
SERVICE
1. Have your saw serviced by qualified service personnel using only identical
replacement parts. This will ensure that the safety of the saw is maintained.

SAFETY INSTRUCTIONS FOR ALL SAWS
1. Keep hands away from cutting area and the blade. Keep your second
hand on the 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 piece being cut in your hands or across your leg. 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.
5. ALWAYS hold the saw by the insulated gripping surfaces when performing
an operation (see page13). Contact with a ”live” wire will also make
exposed metal parts of the power tool”live” and shock the operator.
6. ALWAYS use blades with the correct size and shape of arbor holes. Blades
that do not match the mounting hardware of the saw will run eccentrically,
causing loss of control.
7. 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.
8. DO NOT operate the saw if the guard is damaged or does not operate
correctly.
9. NEVER use the saw with the guard removed.
CIRCULAR SAW BLADE SAFETY WARNINGS
1. The maximum speed listed for the saw (see page 3) should not exceed the
maximum speed marked on the blade.
2. Cracked circular saw blades should be scrapped (repairing is not
permitted). Composite (tipped) circular saw blades, where the tip
dimension is reduced to less than 1 mm, should be taken out of service.
3. Fastening screws and nuts should be tightened using the tools supplied.
4. Clamping surfaces should be cleaned to remove dirt, grease, oil and
water.
5. DO NOT use loose rings or bushes to “make up”bore sizes on circular saw
blades.

PREVENTION OF KICKBACK
Kickback is a sudden reaction to a pinched, bound 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 bound 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.
2. When the 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
and check that saw teeth are not engaged with the material. If the blade
is binding, 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.
5. Blade depth and bevel adjusting locking screws must be tight and secure
before making a cut. If blade adjustment shifts while cutting, it may cause
binding and kickback.
6. Use extra caution when making a “plunge cut” into existing walls or other
blind areas. The protruding blade may cut objects that can cause
kickback.
