8.2 Hydraulic unit
8.3 Hoses
Upon completion of work, the unit must be deactivated.
First of all, decouple the pressure hose then the return hose as described in chapter
“Connecting the equipment”.
Ensure that you put the dust protection caps back on to the couplings.
CAUTION!
Clean off any dirt before controlling the equipment!
WARNING / CAUTION!
In order to carry out maintenance and repair works, tools appropriate for the job
and personal protecting equipment are essential.
Inspections to be carried out:
Visual inspection
Rescue ram
• Cylinder and piston rod are to be free of damage and deformation,
• Correct,
fi rm fi t of the claws,
• Condition of the claws (chipped spots),
• General tightness (leaks),
• Operability of the star grip,
• Existence and stability of handhold,
• Labels completely existent and legibly,
• Couplings must be easy to couple,
• Dust protection caps must be available.
Hoses
• Visual control for visible damage,
• Control for leaks.
Function test
• That the piston stroke can be extracted / retracted to its full length (see chapter “Technical
data”)
• Flawless extension / retraction upon activation of the star grip.
• no further movement of the piston upon interruption of the valve activation during the
process (“dead-man’s” function)
9. Maintenance and service
The equipment is subject to very high mechanical stresses. A visual inspection is to be
carried out after every use: however, at least one visual inspection is to be carried out
annually. These inspections enable the early detection of wear and tear, which means that
punctual replacement of this wearing parts prevents breakages from occurring. A function
test is also to be carried out every three years or should there be any doubt regarding the
safety or reliability of the equipment.
(Please also observe the relevant valid national and international regulations pertaining to
service intervals of rescue equipment). In the Federal Republic of Germany, regular safety
inspections according to the regulations of the Gesetzlichen Unfallversicherung (GUV;
connoted ‘Legal accident insurance’) are mandatory.
