General Power Tool Safety Warnings
WARNING! Read all safety warnings and instructions
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
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.
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
flammable 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.
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. 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 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 circuit interrupter (GFCI) protected
supply. Use of a GFCI 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 influence 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 finger on the switch or energising 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
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) 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.
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 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.
5) BATTERY TOOL USE AND CARE
a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another battery pack.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a
risk of injury and fire.
c) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails,
screws, or other small metal objects that can make aconnection from one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
d) Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause
irritation or burns.
6) SERVICE
a) 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.
Additional Specific Safety Instructions for Adhesive Guns
• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden
wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the tool "live" and shock the
operator.
• Keep hands out of the plunger and plunger rod area of the caulk/adhesive gun. Fingers can be crushed between the
tube holder and the plunger.
• When operating the caulk/adhesive gun overhead, do not have plunger rod in the path of your eyes or head. Plunger
rod may slip back in direction of user. Always wear eyeprotection when using the caulk/adhesive gun.
• Always work in properly ventilated area and wear appropriate respiratory protection if necessary. Fumes from some
caulks and adhesives can be noxious.
• Turn unit off and disconnect battery pack before installing and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable
for one tool may be hazardous when used on another tool. The use of improper accessories may cause risk of injury
to persons.
