Service

Preventing ESD problems

The components inside the tool and controller are sensitive to electrostatic discharge. To avoid future mal-

function, make sure that service and maintenance is carried out in an ESD approved work environment.

The figure below shows an example of an appropriate service work station.

Maintenance Instructions

Service recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive

maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

■

Clean appropriate parts accurately

■

Replace any defective or worn parts

Overhaul

Service must only be carried out by qualified personnel who have access to the Service instruction and/or

have been trained for service on Tensor tools.

The electric motor is a sealed unit and may under no circumstances be opened by anyone else than

Atlas Copco Industrial Technique AB!

If you decide that the electric motor is defect or in need of service, return the complete motor unit to Atlas

Copco Industrial Technique for replacement.

Motors which have been opened by anyone else than Atlas Copco Industrial Technique will not be ser-

viced.

Overhaul and preventive maintenance is recommended at regular intervals, once per year or after a maxi-

mum of 100.000 tightenings, depending on which occurs sooner. More frequent overhaul may be needed

if used at high torque, high cycle rate or long tightening times. If the machine is not working properly, it

should immediately be taken away for inspection.

When dismantling the tool always use the specially designed service tool 4080 0848 80, (two service

tools are required).

At the overhauls, all parts should be cleaned accurately. Defective or worn parts, for example O-rings,

should be replaced.
