Important notes on maintenance
!
Before starting maintenance work under raised
lifting platform components, these must be secured
to prevent unintentional movement.
!
In the event of breakage of a load-bearing
component, the load-bearing structures and drive
system, including the safety devices, must be
checked to prevent falling or lowering of the load-
bearing element. Damaged parts must be replaced.

Maintenance by the user
The maintenance work described below must be
performed by the user.
!
Prior to maintenance, the platform must always be
disconnected from the mains and secured to prevent
unauthorized use.
!
If components are damaged or worn or do not
function properly:
Inform Bosch customer service or an authorized
service agent.
9.5.1 Maintenance
agreement
i
Regular upkeep of the lifting platform is essential to
ensure a long service life and permanent readiness
for use. We recommend concluding a maintenance
agreement with Bosch customer service or an
authorized service agent.
The lifting platform is only to be cleaned using water
containing a small quantity of neutral or slightly alkaline
detergent. The water temperature must not exceed
25 °C.
The components can be wiped with soft cloths or
sponges. Rinse components with clean water after
cleaning.
!
Never use cleaning agents which corrode paintwork,
coatings or sealing materials:
No solvents (esters, ketones, alcohols, halogenated
hydrocarbons)
No abrasive cleaning agents (scouring powder)
No acidic or highly alkaline cleaning agents
!
Never clean the lifting platform with high-pressure or
steam cleaners.
i
A
preservative agent
(e.g. commercially available
transparent cavity sealant) provides extra protection
for the coating. This should be applied in all areas
with exposed edges or where moisture may ingress.
This does not apply to the top edge of the runway.
