Safety Notes

General Safety Rules for Pneumatic Tools

Read and observe all safety warnings and 
instructions. 

Failure to follow the following 

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

Save all warnings and instructions for future reference.

1) Work area safety

a)Keep work area clean and well lit. 

Cluttered or dark 

areas invite accidents.

b)Do not operate the pneumatic tool in explosive at-

mospheres, such as in the presence of flammable 
liquids, gases or dusts. 

While working the work-

piece, sparks can be created which may ignite the 
dust or fumes.

c) Keep children and bystanders away from your 

workplace while operating the pneumatic tool. 

Dis-

tractions from other persons can cause you to lose 
control over the pneumatic tool.

2) Pneumatic tool safety

a)Use compressed air of Quality Class 5 in accord-

ance with DIN ISO 8573-1 and a separate mainte-
nance unit close to the pneumatic tool. 

The com-

pressed air supplied should be free of foreign 
material and moisture to protect the pneumatic tool 
from damage, contamination, and the formation of 
rust.

b)Check the connections and the air supply lines. 

All 

maintenance units, couplers, and hoses should con-
form to the product specifications in terms of pres-
sure and air volume. Too low pressure impairs the 
function of the pneumatic tool; too high pressure 
can result in material damage and personal injury.

c) Protect the hoses from kinks, restrictions, sol-

vents, and sharp edges. Keep the hoses away from 
heat, oil, and rotating parts. Immediately replace a 
damaged hose. 

A defective air supply line may result 

in a wild compressed-air hose and can cause per-
sonal injury. Raised dust or chips may cause serious 
eye injury.

d)Make sure that hose clamps are always tightened 

firmly. 

Loose or damaged hose clamps may result in 

uncontrolled air escape.

3) Personal safety

a)Stay alert, watch what you are doing, and use com-

mon sense when operating a pneumatic tool. Do 
not use a pneumatic tool while tired or under the 
influence of drugs, alcohol, or medication. 

A mo-

ment of inattention while operating a pneumatic 
tool may result in 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 re-
duce personal injuries.

c) Prevent unintentional starting. Make sure that the 

pneumatic tool is switched off before connecting 
it to the air supply, picking it up or carrying it. 

When your finger is on the On/Off switch while car-
rying the pneumatic tool or when connecting the 
pneumatic tool to the air supply while it is switched 
on, accidents can occur.

d)Remove any adjustment tools before switching on 

the pneumatic tool. 

A wrench or key left attached to 

a rotating part of a pneumatic tool may result in per-
sonal injury.

e)Do not overreach. Keep proper footing and bal-

ance at all times. 

This enables better control of the 

pneumatic tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jew-

ellery. 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 col-

lection can reduce dust-related hazards.

h)Do not directly inhale the exhaust air. Avoid ex-

posing the eyes to exhaust air. 

The pneumatic 

tool's exhaust air can contain water, oil, metal parti-
cles and debris from the compressor. This can cause 
damage to one's health.

4) Pneumatic tool use and care

a)Use the clamping devices or a vice to secure and 

support the workpiece. 

Holding the workpiece by 

hand or against your body will not allow for safe op-
eration of the pneumatic tool.

b)Do not overload the pneumatic tool. Use the pneu-

matic tool intended for your work. 

The correct 

pneumatic tool will do the job better and safer at 
the rate for which it is designed.
