CHARACTERISTICS OF THE TOOL
Pneumatic wrench is a tool that is powered with a stream of compressed air at appropriate pressure. Wrenches installed on a
collector make screwing down and unscrewing possible, particularly where a high turning moment is required. Correct, reliable
and safe functioning of the tool depends on correct operation, therefore:
Before operation of the tool can be commenced, the whole manual must be read and kept.
The supplier cannot be held responsible for any damages or injuries which are caused by using the tool in a manner that does not
correspond to its purpose, not observing safety regulations or the recommendations of the present instructions. Using the tool in
a manner that does not correspond to its purpose also cancels the guarantee.
EQUIPMENT
The pneumatic wrench is equipped with a connector that facilitates its connection to the pneumatic system.

GENERAL SAFETY CONDITIONS
WARNING! During operation of a pneumatic tool, it is recommended to always observe the basic safety regulations including
those mentioned below, in order to diminish the risk of fire, electric shock and injury.
Before operation of the tool can be commenced, the whole manual must be read and kept.
ATTENTION!
Read all the instructions mentioned below. If they are not observed, there is a risk of electric shock, fire or injury.
The notion of „pneumatic tool” that is used in the instructions refers to all tools that are powered with a stream of compressed air
at appropriate pressure.
OBSERVE THE FOLLOWING INSTRUCTIONS
General safety rules
For multiple hazards, read and understand the safety instructions before installing, operating, repairing, maintaining, changing
accessories on, or working near the assembly power tool for threaded fasteners. Failure to do so can result in serious bodily injury.
Only qualified and trained operators should install, adjust or use the assembly power tool for threaded fasteners. Do not modify
this assembly power tool for threaded fasteners. Modifications can reduce the effectiveness of safety measures and increase the
risks to the operator. Do not discard the safety instructions; give them to the operator. Do not use the assembly power tool for
threaded fasteners if it has been damaged. Tools shall be inspected periodically to verify that the ratings and markings required
by this part of ISO 11148 are legibly marked on the tool. The employer/user shall contact the manufacturer to obtain replacement
marking labels when necessary.
Projectile hazards
Failure of the workpiece, of accessories or even of the inserted tool itself can generate high-velocity projectiles. Always wear
impact-resistant eye protection during the operation of the assembly power tool for threaded fasteners. The grade of protection
required should be assessed for each use. Ensure that the workpiece is securely fixed.
