8.1 Cutters / Combi tools
8.2 Hydraulic unit
Once work has been completed, the blade arms are to be closed so that there is a tip distance
of just a few mm. This relieves the hydraulic and mechanical strain on the equipment.
Free the rescue equipment of any stubborn dirt which may have become attached during
use.
If the equipment is to be stored for a longer period of time, the exterior is to be cleaned
completely and the mechanically mobile parts are to be lubricated.
Avoid storing the rescue equipment in a damp environment.
Observe also the separate manual for the hydraulic hoses.
REMARK:
Never store the cutter / combi tool with fully closed blade arms! The complete
closure of the blade arms can cause hydraulic and mechanical stress to build
up again.
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.
8. Dismantling the equipment / deactivation following
operation
The equipment are 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 every
six months. These inspections enable the early detection of wear and tear, which means
that punctual replacement of this wearing parts prevents breakages from occurring. Also
regularly check the torque of the pivot bolt. (Torque M
A
see “Technical Data”)
Every three years also a crack test of the blades are essential. Therefore a special crack
testing kit is is available.
Every three years or if there is any doubt regarding the safety or reliability of the equipment,
a function test must also be performed. (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.
CAUTION!
Clean off any dirt before controlling the equipment!
9. Maintenance and service
WARNING / CAUTION!
In order to carry out maintenance and repair works, tools appropriate for the job
and personal protecting equipment are essential.
