English (original instructions)

WARNING:

Read all safety warnings and all 

instructions. 

Failure to follow the warnings and 

instructions may result in electric shock, fire and/or 
serious injury.

WARNING:

 To reduce the risk of injury, read the 

instruction manual.

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 a 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 energizing 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 

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.

GENERAL POWER TOOL SAFETY WARNINGS
