General safety rules

WARNING.

 Read all instructions. Failure to follow all 

instructions listed below may result in electric shock, 

fire and/or serious injury. The term “power tool” in all of 

the warnings listed below refers to your mains operated 

(corded) power tool or battery operated (cordless)  

power tool.

Save these instructions
1. Work area
a. Keep work area clean and well lit.

 Cluttered and 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.

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 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 

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 these devices 

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.
