5.4.3 Set all controls in neutral, stop the engine, apply the parking brake, and
allow the engine and fluids to cool.

Burn hazard! Avoid contact with the engine oil when draining the
engine. Hot oil can burn!
Note: In the interests of environmental protection, place a plastic sheet
and a container under the machine to collect any liquid that drains off.
Dispose of this liquid in accordance with environmental protection
legislation.
5.4.4 Unscrew the oil drain plug and allow the oil to drain into a 1–1.5 liter
(1–1.5 quarts) container.
5.4.5 Clean the oil drain plug and attach a new seal to it.

5.4.7 Unscrew the filler cap of the oil filter housing. Check the condition of

1.1–1.2 liters (1–1¼ quarts).
5.4.10 Wet the O-ring and threads of the filler plug with high-temperature
grease available from your Hatz Dealer. Then, reinstall the filler plug.
5.4.11 Run the engine for two minutes. Turn off the engine and check the
engine oil level again. Add engine oil as necessary.
5.4.12 Make sure that there is no oil leakage past the filler cap.
