1.1 Warnings and notes

Warning notes are identified by a signal word and a pictogram:

• The signal word describes the severity and the probability of the impending danger.

• The pictogram describes the type of danger.

WARNING!

Indicates a potentially hazardous situation

which, if not avoided, could result in death or serious injury.

CAUTION!

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate

injury or property and environmental damage. If this warning is not observed, injuries, property

or environmental damage may occur.

Safety

1.2 Basic requirements for safe working practices

You should read all instructions.

Failure to observe the instructions listed below can result in serious injuries.

1.3 Operator training

Operators must be trained in correct handling of the tool. The user must make the operating

manual available to the machine operator and ensure that the operator has read and understood

it. The tool may be connected, used, serviced and repaired by qualified persons only. The tool

may be repaired by authorized technicians only.

CAUTION!

➔ Work with a maximum working pressure of 101.5 psi (700 kPa) (measured as the air inlet

tube of the tool).

➔ Before initial operation, check that the suspension bail is properly fastened to the bal-

ancer.

➔ 7PTHDA: When air inlet from top is used make sure, that plug is properly mounted accord-

ingly.

➔ If you hear unusual noises or vibrations, switch off the tool immediately.

Shut off the air supply immediately.

➔ Before carrying out repairs, adjusting the torque or replacing screw bits, disconnect the

tool from the compressed air line.

➔ The compressed air line must be depressurized before disconnecting it.

➔ Never use the air hose to hold, raise or lower the tool.

➔ Air hoses, the suspension bail and fittings must be regularly checked for damage and

wear. Replace if necessary.

➔ Always carry out assembly according to Chapter 8 Spare parts, page 25.

➔ Use only accessory parts authorized by Apex Tool Group

(see product catalog).

➔ Adjust the torque using the provided hex wrench only. Never use an angular wrench.

➔ Only use screw inserts for machine-controlled fastening tools.

➔ Make sure that the screw bits are securely inserted.

➔ Inspect screw bits for visible damage and cracks.

Replace damaged screw bits immediately.

➔ The operation, maintenance and repair conditions set forth in the operating instructions

must be observed.

➔ Follow generally valid and local safety and accident prevention rules.
