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. When using an
extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and overheating.
The following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier
the cord.

3) 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
toolsmay result in serious personal injury.

or medication. A moment of inattention while operating power
toolsmay 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
personal injuries.

c) 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.

d) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached 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 unex-
pected 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. Air vents often cover moving parts and should also
be avoided.

4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job better
and safer at the rate for which it was designed.
