Safety and operating instructions

Lubrication-free models:

• In the case of lubrication-free tools it is up to the

customer to decide on the peripheral equipment

to be used. However, it is no disadvantage if the

compressed air contains a small quantity of oil

e.g. supplied from a fog lubricator (DIM) or Dosol

system. This does not apply to turbine tools, which

should be kept oil free.

Compressed air connection

• The machine is designed for a working pressure

of 6–7 bar = 600–700 kPa = 87–102 psi.

• Blow out the hose before connecting.

Handling

Tightening torque

The torque obtained depends on air pressure and

tightening time on the actual joint. Extensions and

worn sockets will reduce the delivered torque. The

impact wrench should be used within the specified

torque range. Never use the machine over recommen-

ded maximum torque. Might result in improper

function and faster wear.

Test methods

A static torque measurement is recommended for

impact wrenches.

For test on hydraulic tension tester and for test on

joints.

Maintenance

Service instructions

Overhaul and preventive maintenance is recommen-

ded at regular intervals once per year or after maxim-

um 100.000 tightening depending on which occurs

sooner. More frequent overhaul may be needed if

the machine is used in heavy-duty operations. If the

machine not is working properly, it should immedi-

ately be taken away for inspection.

The strainer at the air inlet and the exhaust silencer

should be cleaned frequently or replaced in order to

prevent clogging, which decreases the capacity.

At the overhauls, all parts should be cleaned accur-

ately and defective or worn parts (i.e. O-rings, vanes)

should be replaced. It is important that the machines

threaded connections are tightened properly; i.e. in

accordance with the specifications on the exploded

views. Before assembly, lubricate the threads with

grease.

All o-rings should be greased before assem-

bling.

Rust protection and internal cleaning

Water in the compressed air, dust and wear particles

cause rust and sticking of vanes, valves etc. An air

filter should be installed close to the machine (see

'Air quality'). Before longer standstills, flush with

oil (some drops) into the air inlet, run the machine

for 5-10 seconds when absorbing the oil in a cloth.
