POWER TOOL SAFETY WARNINGS
1) WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. Do not operate power tools 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 a power tool.
Distractions can cause you to lose control.
2) ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. Do not abuse the power cable. Never use it for carrying, pulling or
unplugging the power tool. Keep the power cable away from heat, oil,
sharp edges or moving parts. Damaged or entangled cables increase the
risk of electric shock.
4. When operating a power tool 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 power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply.
3) PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool 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 power tools with your finger on the switch or plugging
in power tools that have the switch on invites accidents.
4. Remove any wrench before turning the power tool on. A wrench left
attached to a rotating part may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. Dress properly. 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.
4) POWER TOOL USE AND CARE
1. Do not force the power tool. 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.
2. Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the plug from the power source before changing accessories,
or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
4. Store idle tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate it. Power tools
are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power
tool’s operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
6. Use the power tool 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 power tool for operations
different from intended could result in a hazardous situation.
7. The performance of this tool may vary, depending upon variations in line
voltage. Extension cable usage may also affect performance.
5) SERVICE
1. Have your power tool serviced by qualified service personnel using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.
6) BUFFER SPECIFIC WARNINGS
1. DO NOT get the buffer/polisher wet or use in damp or wet locations.
2. DO NOT switch the buffer/polisher on whilst the mop is in contact with the
workpiece.
3. Avoid polishing dissimilar metals with the same buffing mop; galvanic
corrosion may occur.
