GENERAL SAFETY RULES
WARNING! Read all safety warnings
and all instructions. Failure to follow the
warnings and instructions may result in
electric shock, re and/or serious injury.
1) Work Area Safety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c) Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control
Save all warnings and instructions for future
reference. The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
2) 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. Unmodied 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.

1.800.417.9272 www.ezgmfg.com 7
GENERAL SAFETY RULES
2) Electrical Safety (continued)
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk of
electric shock.
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 Ground Fault Indicator (GFI)
protected supply. Use of an GFI reduces the risk of
electric shock.
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 inuence
of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in
serious personal injury.
b) Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce 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 nger on the switch or
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.
energizing power tools that have the switch
on invites accidents.

GENERAL SAFETY RULES
3) Personal Safety (continued)
e. 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 jewelry.
Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
g) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust-related hazards.
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.
b) 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.
c) Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
d) 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.

GENERAL SAFETY RULES
4) Power Tool Use and Care (continued)
e) 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.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into ac
count the working conditions and the work to be per
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
