What to verify? Execute, service or repair if required !!
•
General condition: outside rubber coat is intact, inside steel braids are not visible
•
Routing & guidance, protection against squeezing, sheering or rubbing
•
Fragility & porosity
•
Age: to be replaced every 4th year (+ fill out the Maintenance & Repair Report)
General condition
•
•
Corrosion, fixation
•
Hydraulic system is free from leaks, both during operation & at rest.
What to verify? Execute, service or repair if required !!
General condition, no cracks or deformation in the mechanical parts & mounting brackets
•
•
Protection against corrosion, sealing of all the holes
•
Condition of the cover and its fixation
•
Hydraulic system is free from leaks, both during operation & at rest.
Check oil level & refill if required.
•
•
Oil type: ISO 22 as standard
(other types used as option - check before refill)
•
Oil level: The max. oil level reaches to 30mm below the fill-up inlet when the platform is at the
ground. The min. oil level reaches to 40mm above the under side of the reservoir when the plat-
form is closed.
•
Change oil & clean filter.
To remove all the oil, lift the rear of the vehicle off the ground, so that the lift cylinders
can contract fully, and no oil remains in the cylinders.
•
Hydraulic system is free from leaks, during execution of all functions.
•
If oil needs to be refilled, search for reason and repair.
Purge the hydraulic system:
•
LOWER the platform completely (below ground level if possible), until the cylin-
ders are fully retracted, and continue to push the function LOWER for another 20 sec.
(*) also after each replacement of hydraulic pipes or revision of hydraulic cylinders
•
General condition, correct amperage
•
Corrosion, burn marks / sparkles
•
Fixation & tightening of all cable & wire connections
General condition
•
•
Verify the maximum oil pressure in function of the nominal capacity of the HTL, and adjust if
required (HTL lifts too little or too much weight). Max. oil pressure = 180 BAR.
