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.
