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
depowered 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.
Tyres: The quality of the tyres greatly affects the stability and the driving behaviour
of the fork lift truck. Changes must only be made following consultations with the
manufacturer. When replacing wheels or tyres, it must be ensured that the fork lift
truck remains level (tyres and wheels must always be replaced in pairs, i.e. left and
right together).
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),
lubrication 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
themselves 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
hydraulic components, also renew the hoses in this hydraulic system.
