Hazards due to hose failure & oil leakage

Hose assemblies may fail abruptly and unexpect-

edly for a variety of reasons. Hydraulic oil shooting

out at high pressure and/or at high speed can

cause serious personal injury, severe damage to

objects, and environmental pollution.

Examples of potential hazards

• Bursting hose components

• Whipping hose ends

• Oil spray leakage

• Coupling blow-off

Make sure that:

The design and operation of tools and machines

complies with the existing safety regulations.

Inspect hose assemblies for damage and wear at

regular intervals; if possible, before each use.

Inspect hose sets in unpressurised condition; use

implements when necessary.

Defective or damaged hose assemblies must be

replaced immediately. Do not attempt to repair

them. Always use new components.

Never try to locate a leak with your hands!

If leakage occurs, shut down the hydraulic pump

immediately. Never try to locate the leak with any

part of the body when the hose set is pressurised.

Use a suitable implement to inspect the hose for

damage.

To avoid hydraulic oil escaping under high pressure,

make sure all hydraulic hoses (coupling and nip-

ple) are properly connected and secured with the

alkitronic® NOVA and the load (motor, cylinder or

torque wrench).

Do not mix alkitronic® products with substitute

copies!

The interface between the coupling and the

nipple is crucial. alkitronics unique tolerances

and precision must not be tampered with. An

improper solution caused by using non-alkitronic

devices, may lead to an incorrect connection, or

even worse an accidental disconnection which

results in hydraulic oil shooting out at high pressure.

Do not extend hydraulic hoses without interme-

diate coupling.

Reversing the couplers for extension results in

reverse flow and reverse control of the hydraulic

tool. Non-compliance with these regulations may

lead to faulty functions and damage to the tool or

serious injuries to the operator.

A fluid injection injury must always be treated as

a medical emergency that requires prompt and

accurate diagnosis and treatment.

Possible leaking oil is hazardous to the environ-

ment. It must be safely collected and properly

disposed of.

2.4

General electrical and mechanical risks

The alkitronic® NOVA may only be operated, if the

power supply matches the electric performance

specifications of the unit and all hydraulic con-

nections to the load (motor, cylinder or hydraulic

torque wrench) are tight and non-reversible. The

load should comply with the minimum require-

ments for safe operation.

In case of damage and repair, the hydraulic pump

must be separated from the power supply and im-

mediately be checked by a qualified technician for

electrical safety and mechanical defects. All safety

and mechanical defects must be resolved before

resuming operation.

In case of a power failure or malfunction, shut-off

the hydraulic pump immediately via the power

switch, seperate the pump from the power supply

and put the torque wrench in a safe position.

To avoid the risk of tilting or falling, the alkitronic®

NOVA must always be set-up securely. When work-

ing in high places, it should be secured.
