Maintenance
Faults and how to remedy
Before all maintenance and cleaning work, pull off the spark plug connector.
After each use, clean the scarifier with a hand brush.
Do not by any means spray down with water. Store the scarifier in a dry room.
Always change the engine oil with the engine warm, and the tank empty.
Do so the first time after the first five hours of operation. Then every 25 hours of operation, or no later than the end of the mowing season.
When used under difficult or dusty conditions, do so more frequently. Open the oil filling connection piece, slowly tilt the scarifier to the side
and let the oil drain out. Dispose of the used oil according to local regulations. Note: Oil must not get into the ground.
Clean the spark plug
Dirty spark plugs reduce the engine performance. Clean the spark plug and check to be sure the spark plug gap is correct (0.76 mm).
Clean the air filter
See the Operating Instructions from the manufacturer of the engine (enclosed).
Replace the replaceable roller/Cleaning work (Fig. W1)
Pull off the spark plug connector.
To replace the replaceable roller* and to clean the front chassis area, tilt the scarifier to the rear as shown
in the illustration.
Before doing so:
Empty the tank and move the top part of the grip forward (see “Only move top part of grip” Fig. M4/M5).
* Only at WOLF service shops!
Wear indicator / Scarifying blade (Fig. W2)
When worn to the wear indicator (a), have the complete replaceable roller replaced at a WOLF service shop.
