ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tools.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increases the risk of electric shock.
PERSONAL SAFETY
a) 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 serious personal injury.
b) 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 the
risk of personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to
power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key to a
rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
f) 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.
g) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands
of untrained users.
h)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.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.

l) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
n) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
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.
