MAINTENANCE AND STORAGE
Important!
Never work on or touch conducting parts on the ignition unit with the engine running. Always pull the spark
plug boot from the spark plug before starting any work of care or maintenance. Never perform any work on the
machine while it is running. Any work not described in these Operating Instructions must be performed by an
authorized service workshop only.
a. Cleaning
The scarifier should be cleaned thoroughly every time after it has been used. This particularly applies to its
underside and the blades. To do so, tip the scarifier slightly on to its side and remove the dirt.
Important: Before you tip the equipment, the petrol tank must be emptied to prevent petrol leaking out.
Ideally you should use a conventional petrol extraction pump for this purpose.
b. Servicing
Checking the oil level
-
Set the equipment down on a flat, level surface.
-
Unscrew the oil dipstick by turning it anticlockwise. The oil level must be as shown in Figure 10.
Important! Never run the engine with no or too little oil. This can cause serious damage to the engine.
c. Changing the oil
-
Change the engine oil every year before the start of the season (in addition to the information in the
petrol service manual) when the engine is warm.
-
Use only recommended engine oil.
-
Place a suitable oil drip tray beneath the oil drain screw.
-
Remove the oil filler screw (Fig. 9 / Item A).
-
Undo the oil drain screw (Fig. 9 / Item B) and drain the oil into a suitable container.
-
Close the drain screw again when all the used oil has been drained.
-
Pour engine oil into the equipment as shown in Figure 10.
-
Dispose of the used oil in accordance with applicable regulations.
d. Care and adjustment of the cables
-
Oil the cables at regular intervals and check that they move easily.
e. Servicing the air filter
-
Soiled air filters reduce the engine output by sup‐ ply too little air to the carburetor. Regular checks are
therefore essential. The air filter should be checked after every 50 hours of use and cleaned if
necessary. If the air contains a lot of dust, the air filter should be checked more frequently.
-
Remove the air filter as shown in Fig. 11‐13.
