STRUCTURE AND FUNCTION | 25
»
Every three years, or in the event of doubts about the safety
or reliability, carry out an additional functional and load test (as
per DGUV 305-002 or specific national directive).
»
Replace hoses every 10 years! The date (code letters or
quarter/year) is specified on the hose bonding.
»
Ensure that the hoses are not exposed to tension or torsion
(turning).
»
Do not kink the hoses or draw them over edges (smallest
bend radius 40 mm).
»
Do not subject the hoses to high temperatures.
»
Protect hoses from contact with materials that can cause
damage to the outer covering e.g. acids, alkalis, or solvents.
Hydraulic oil
All cutters are designed and tested for WEBER hydraulic oil ID No. 804932. This oil possesses a
particularly high purity level and also works flawlessly at temperatures below zero, down
to -20° C.
With limitations in the low temperature range (low output), however, a standard oil (mineral
based) of viscosity class HLP 10 or HVLP 10 can be used in keeping with DIN 51502.
NOTE !
We recommend the following hydraulic oils for trouble-free operation of
WEBER rescue devices:

AERO Fluid 41 (Shell)
»
Univis HVI-13 (Esso)
»
Aero-hydraulic 520 (Total)
»
Hydraulik DB (Castrol)
»
Renolin/MR310 (Fuchs)
»
HVI Extra 380 (Maier & Korduletsch)
»
