7 Maintenance
When cleaning the engine with a water or steam jet, the humidity
penetrating the electronics causes it to fail and leads to engine damage!
► The engine must be cold.
► Do not point the water jet directly at any of the electric sensors such as
temperature and oil pressure switches or control valves.
► Protect all electric parts, such as the alternator, connectors, relays, etc.
from humidity.
► If water contacts electrical components, dry them with compressed air
and apply contact spray to them.
Clean the engine compartment as follows:
1. Park the machine in a wash bay or place suitable for washing.
2. Stop the engine. See “Preparing lubrication”.
3. Clean the machine.
Cleaning the seat belt
Keep the seat belt clean, as coarse dirt can impair the proper functioning
of the seat belt buckle.
Clean the seat belt (which remains fitted in the machine) with a mild soap
solution only. Do not use chemical agents as they can destroy the fabric!
Cleaning the shatter protection
Clean the window only with water and a mild soap solution.
Do not use aggressive detergents!
Do not use brushes, steel wool or similar abrasive means. Never wipe
dust in a dry state.
Threaded fittings and attachments
All threaded fittings must be checked regularly for tightness.
• Engine fastening screws
• Fastening screws on the hydraulic system
• Line, bucket teeth and pin fastenings on the attachment
Retighten loose connections immediately, and have them immediately
replaced by a Wacker Neuson service center if necessary.
