If the fork lift truck is to be cleaned using a water jet or a high-pressure cleaner, all
electric and electronic components must be carefully covered beforehand because
moisture can lead to incorrect functioning.
Cleaning by means of a steam jet is not permitted.
Upon completion of cleaning work, the operations detailed in the section “"Recommis-
sioning”" must be performed.
Work on the electric system: Work on the electric system of the truck must only be
performed by personnel specially trained for such operations. Before commencing
any work on the electric system, all measures required to prevent electric shocks
have to be taken. For battery-operated fork lift trucks, the truck must also be depow-
ered by removing the battery plug.
Welding operations: To prevent any damage to electric or electronic components,
these have to be removed from the fork lift truck before any welding operations are
undertaken.
Settings: When repairing or replacing hydraulic, electric or electronic components or
assemblies, all truck-specific settings have to be retained.
Wheels: The quality of wheels affects the stability and performance of the truck.
When replacing wheels fitted at the factory, only use manufacturer’'s original spare
parts. Otherwise the truck's rated performance cannot be ensured.
When replacing wheels, ensure that the truck does not slew (e.g. always replace
wheels in pairs, i.e. left and right wheels at the same time).
Lift chains: The lift chains wear rapidly if not lubricated. The intervals in the service
checklist apply to normal duty. If requirements are higher (dust, temperature), lubri-
cation is required more often. The specified chain spray must be used as specified.
The external application of grease does not provide sufficient lubrication.
The chain tensioners must be adjusted in such a manner that they can adapt them-
selves to the pulling direction of the chain. Pretensioning the tensioner head against
the mounting is not allowed. A minimum distance of 20 mm must be kept.
Hydraulic hoses: The hoses must be renewed every six years. When replacing hy-
draulic components, also renew the hoses in this hydraulic system.
