IMPORT ANT INFORMA TION
Read this information carefully before use. Failure to follow all
instructions listed below may result in electric shok, fire and/or
serious injury. The term “power tool” in all of the warnings
listed refers to your battery operated (cordless) power tool.
Make sure all operators have adequate access to the following instructions.
GENERAL SAFETY
INTRODUCTION
1) Keep 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.
ELECTRICAL SAFETY
4) Power plugs must match the outlet. Never modify the plug in
any way. Unmodified plugs and matching outlets will
reduce the risk of electric shock.
5) Avoid body contact with earthed or ground surfaces such as
pipes radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is earthed or
grounded
6) DO NOT expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
7) DO NOT abuse the power cord. Keep cord away from heat,
oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
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 serious personal injury.
2) Use safety equipment. Always were 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. Carrying power tools with your
finger on the switch invites accidents.
4) DO NOT over reach. Keep proper footing and balance at all
times. This enables better control of the power tool in
unexpected situations.
5) Dress properly. DO NOT wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving part s.
Loose clothes jewellery or long hair can be caught in
moving parts.
POWER TOOL USE AND CARE
6) 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.
WORK AREA
Thank you for purchasing a Macnaught BG100 Battery
Operated Grease Gun.

7) 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.
9) Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
8) 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.
10) Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, 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.
SERVICE
Have your power tool serviced by a qualified repairperson
using only identical replacement parts. This will ensure that
the safety of the power tool is maintained.
