General safety instructions

WARNING.

 Read and understand all instructions.  

Failure to follow all instructions listed below may result  

in fire and/or serious injury. 

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) 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 a dust mask, non-skid 

safety shoes, hard hat, or hearing protection used for 

appropriate conditions will reduce personal injuries.

c) Remove any adjusting key or wrench before turning 

the tool on.

 A wrench or a key that is left attached to 

a rotating part of the power tool may result in personal 

injury.

d) Do not overreach. Keep proper footing and balance 

at all times.

 This enables better control of the power tool 

in unexpected situations.

e) 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.

f)  If devices are provided for the connection of dust 

extraction and collection facilities ensure that these 

are connected and properly used.

 Use of these 

devices can reduce dust-related hazards.

3)  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) Turn tool off completely 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 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.
