To fill fuel
If available, use low-emission/alkylate gasoline. If low-

quality unleaded gasoline or leaded gasoline. Use
gasoline with an octane number of 90 RON out of North
America (87 AKI in North America) or higher, and with a
maximum of 10% ethanol (E10).
CAUTION: Do not use gasoline with an
octane number less than 90 RON out of
North America (87 AKI in North America).
This can cause damage to the product.

Maintenance

CAUTION: Do not set the cutting height too
low. The blades can hit the ground if the
surface of the lawn is not level.
To start the product
1. Make sure that the ignition cable is connected to the
spark plug.
2. The very first time you start the product, press the
primer bulb 5 times. The next time you start the
product when the engine is cold, press the primer
bulb 3 times.
3. Stay behind the product.
4. Hold the engine brake handle against the handlebar.
5. Hold the starter rope handle with your right hand.
6. Slowly pull out the starter rope until you feel some
resistance.
7. Pull with force to start the engine.(Fig. 26 )
WARNING: Do not twist the starter rope
around your hand.
To stop the product
• To stop the engine, release the engine brake handle.
To get a good result
• Always use a sharp blade. A blunt blade gives an
irregular result and the cut surface of the grass
becomes yellow. A sharp blade also uses less
energy than a blunt blade.
• Do not cut more than ⅓ of the length of the grass.
Cut first with the cutting height set high. Examine the
result and lower the cutting height to an applicable
level. If the grass is very long, drive slowly and cut 2
times if necessary.
• Cut in different directions each time to prevent
stripes in the lawn.
Maintenance schedule
