Safety Instructions
General Power Tool Safety Warnings
WARNING! Read all safety warnings and instrucons.
Failure to follow the warnings and instrucons may result in electric shock, re
and/or serious injury.
Save all warnings and instrucons for future reference.
The term ″power tool″ in the warnings refers to your baery-operated (cordless)
power tool.
Work area safety
● Keep work area clean and well lit. Cluered or dark areas invite accidents.
● Do not operate power tools in explosive atmospheres, such as in the presence of amma-
ble liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
● Keep children and bystanders away while operang a power tool. Distracons can cause
you to lose control.
Electrical safety
● Do not expose power tools to rain or wet condions.
Water entering a power tool will increase the risk of electric shock.
Personal safety
● Stay alert, watch what you are doing and use common sense when operang a power tool.
Do not use a power tool while you are red or under the inuence of drugs, alcohol or
medicaon. A moment of inaenon while operang power tools may result in serious
personal injury.
● Use personal protecve equipment.
Always wear eye protecon. Safety equipment such as dust mask, non-skid safety shoes,
hard hat, or hearing protecon used for appropriate condions will reduce personal inju-
ries.
● Prevent unintenonal starng. Ensure the switch is in the o-posion before connecng
the baery pack, picking up or carrying the tool.
Carrying power tools with your nger on the switch or energizing power tools that have
the switch on invites accidents.
● Remove any adjusng key or wrench before turning the power tool on.
A wrench or a key le aached to a rotang part of the power tool may result in personal
injury.

● Do not overreach. Keep proper foong and balance at all mes. This enables beer control
of the power tool in unexpected situaons.
● 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.
● If devices are provided for the connecon of dust extracon and collecon facilies, en-
sure these are connected and properly used. Use of these devices can reduce dust-related
hazards.
● Only use safety equipment that has been approved by an appropriate standards agency.
Unapproved safety equipment may not provide adequate protecon. Eye protecon must
be ANSI-approved and breathing protecon must be NIOSH-approved for the specic
hazards in the work area.
Power tool use and care
● Do not force the power tool. Use the correct power tool for your applicaon. The correct
power tool will do the job beer and safer at the rate for which it was designed.
● Do not use the power tool if the switch does not turn it on and o.
Any power tool that cannot be controlled with the switch is dangerous and must be re-
paired.
● Disconnect the baery pack from the power tool before making any adjustments, chang-
ing accessories, or storing power tools.
Such prevenve safety measures reduce the risk of starng the power tool accidentally.
● Store idle power tools out of the reach of children and do not allow persons unfamiliar
with the power tool or these instrucons to operate the power tool. Power tools are dan-
gerous in the hands of untrained users.
● Maintain power tools. Check for misalignment or binding of moving parts, breakage of
parts and any other condion that may aect the power tool’s operaon. If damaged,
have the power tool repaired before use. Many accidents are caused by poorly maintained
power tools.
● Keep cung tools sharp and clean. Properly maintained cung tools with sharp cung
edges are less likely to bind and are easier to control.
● Use the power tool, accessories and tool bits etc. in accordance with these instrucons,
taking into account the working condions and the work to be performed. Use of the pow-
er tool for operaons dierent from those intended could result in a hazardous situaon..
Baery tool use and care
● Recharge only with the charger specied by the manufacturer. A charger that is suitable

for one type of baery pack may create a risk of re when used with another baery pack.
● Use power tools only with specically designated baery packs. Use of any other baery
packs may create a risk of injury and re.
● When baery 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 a connecon from
one terminal to another. Shorng the baery terminals together may cause burns or a re.
● Under abusive condions, liquid may be ejected from the baery; avoid contact.
If contact accidentally occurs, ush with water.
If liquid contacts eyes, addionally seek medical help. Liquid ejected from the baery may
cause irritaon or burns.

13. The warnings, precauons, and instrucons discussed in this instrucon manual cannot
cover all possible condions and situaons that may occur. It must be understood by the
operator that common sense and cauon are factors which cannot be built into this prod-
uct, but must be supplied by the operator.
Vibraon Safety
This tool vibrates during use.
Repeated or long-term exposure to vibraon may cause temporary or permanent physical
injury, parcularly to the hands, arms and shoulders.
To reduce the risk of vibraon-related injury:
1. Anyone using vibrang tools regularly or for an extended period should rst be examined
by a doctor and then have regular medical check-ups to ensure medical problems are
not being caused or worsened from use. Pregnant women or people who have impaired
blood circulaon to the hand, past hand injuries, nervous system disorders, diabetes, or
Raynaud’s Disease should not use this tool.
If you feel any symptoms related to vibraon (such as ngling, numbness, and white or
blue ngers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicone reduces the blood supply to the hands and ngers,
increasing the risk of vibraon-related injury.
3. Wear suitable gloves to reduce the vibraon eects on the user.
4. Use tools with the lowest vibraon when there is a choice.
5. Include vibraon-free periods each day of work.
6. Grip tool as lightly as possible (while sll keeping safe control of it). Let the tool do the
work.
