GENERAL SAFETY 

 
The improper use of pneumatic equipment is unsafe and may result in personal injury. It is important that 
operators have read, understood and comply with all instructions in this user guide. 
 
If more than one individual is involved in the operation of the equipment then all must read the user 
guide. Good communication must be established to prevent accidents or misunderstandings. 
 
Operators must be equipped with the following personal protective equipment (PPE):- 

 

Eye Protection (Safety Glasses / Goggles) 

 

Safety Footwear (Steel Toe Cap Boots) 

 

Heavy Gloves 

 
Impact quality sockets must be secured to the tool square drive by means of a pin and ring combination. 
 
Care must be taken not to exceed the maximum working pressure of the equipment. See the torque chart 
provided. Failure or breakup of components may result in personal injury. 
 
Direct the tool exhaust away from operator / personnel. 
 
Take care not to stand on, run over or trip over pneumatic hoses. Injury may result. To minimise danger 
ensure that these lines are not run across walkways, ladders, roadways and doorways, etc and that people 
likely to pass through the working area are aware of the danger. 
 
To prevent entanglement with rotating parts operators must not wear loose clothing, ties, jewellery etc… 
Long hair must be tied back.. 
 
Always keep hands, fingers and body parts clear of the reaction arm at all times. Trapping in this area can 
result in serious personal injury. 
 
Before use, check the pneumatic hoses are not cut, split, kinked or damaged in any way. If in doubt 

Do 

not use

 
All pneumatic equipment and ancillary products should be inspected for damage and irregularities prior to 
use. If in doubt 

Do not use.

 

 
Never lift or drag hoses or cables. This weakens the swagings and puts unnecessary stress on threads and 
couplings. Subsequent failure may result in causing injury. 
 
Do not use in the presence of explosive gases or flammable liquids - fire/explosion hazard.
