Maintenance and service

The platform floor truck is very low maintenance when being used in dry normal atmospheres. Before each use
the platform floor truck should be checked for smooth function and ease of movement of all moving parts.
If failures or faults preventing safe operation are detected during this inspection, the platform floor truck must
only be used when the complaints have been remedied.
If the platform floor truck is used in special ways, possibly in very dusty or even moist conditions, the need for
maintenance respectively service increases. If the platform floor truck is used with maximum load at all times,
moving parts and bearing locations should be greased more often, in order to provide for ease of movement. If
foreign matter has penetrated the tread of the wheels preventing smooth rolling, the wheels should be replaced.

Hydraulic oil

The oil pump requires approx. 400ml hydraulic oil. The standard quality oil should be used between +5 and
+40° C and the special low-temperature oil should be used at ambient temperatures between – 35 and +5° C .
