Cleaning

The paintwork on the truck crane will continue to harden for the first three
months.
•
During this period the crane may be cleaned only with cold water.
•
Do not use high-pressure or steam jet cleaning equipment during this
period.
•
Avoid water temperatures above 60 °C (140 °F), even after this period.
•
Do not use corrosive cleaning agents that might damage the paint.
•
Never hold the spray nozzle of your cleaning unit at right angles to the sur-
face you are cleaning, and ensure that it is at a sufficient distance away
from the surfaces to be cleaned.
Risk of accidents from a misdirected high pressure water jet.
When working with high-pressure and steam-jet cleaners, the water jet will
be deflected by crane parts and could spray into your face and eyes at high
speed and great pressure.
Always wear a face guard when cleaning the truck crane with high-pressure
and steam-jet cleaning equipment.
•
To prevent damage to the gaskets, never point the spray nozzle directly at
them.
•
Never point the spray nozzle at electrical equipment, relay and switch
boxes, suction and ventilation filters or control elements and lubricated
surfaces.
•
To prevent corrosion, relubricate all slide faces after cleaning.
•
Keep all electric and hydraulic connections free of dirt. Check the connect-
ing points for dust, foreign bodies and moisture before installation. This
also applies to protective caps and bridging plugs.
The components specified in the next section are particularly at risk.
•
After cleaning with high-pressure or a steam jet equipment, activate inter-
mediate lubrication on the central lubrication system (
mediate lubrication , p. 7 - 121). Lubricate all remaining lubricating points
using a grease gun.
