Unauthorized modifications and changes to the

LEVA Hydraulic pump remove any liability from

alki TECHNIK GmbH and lead to the expiry of the

declaration of conformity! In these cases, the user is

liable for damage caused by the use of the device.

Possible risks with hydraulic components

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 pres-

sure, make sure all hydraulic hoses (coupling and

nipple) are properly connected and secured with

the alkitronic® LEVA and the load (hydraulic torque

wrench).

Do not mix alkitronic® products with substitute

copies!

The interface between the coupling and the nipple

is crucial. alkitronics unique tolerances and preci-

sion must not be tampered with. An improper solu-

tion 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.

2.4

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.

General electrical and mechanical risks

The LEVA Hydraulic Pump may only be operated,

if the power supply matches the electric perfor-

mance specifications of the unit and all hydraulic

connections to the load (motor, cylinder or hydrau-

lic 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 separate

the pump from the power supply and put the

torque wrench in a safe position.

To avoid the risk of tilting or falling, the LEVA Hy-

draulic Pump must always be set-up securely.

When working in high places, it should be secured.

Never remove the transport frame, otherwise sta-

bility is endangered!
