4. Do not mow excessively steep slopes.
5. The best result will be achieved if the grass is dry. Wet grass will tend to clog the
blade and the grass collection system.
6. Grass grows at different rates at different time of the year. Never use the lowest
cutting height for the rst cut of the season or in drought conditions.
7. Only about one thirds of the grass height should be cut.
8. Do not remove grass debris in the mower casing or on the blade by hand or with your
feet. Instead use suitable tools such as a brush or broom.
Emptying the grass bag

Tilt the lawnmower towards the oil llercap , have a container ready to catch the oil and
remove the dipstick . once the oil has been emptied , replace the dipstick and wipe clean
any spillages.
Rell with SAE30 oil. When the dipstick is rested on the ller pipe (i.e. not turn in pace ),
the oil level must be between the min and max marks on the dipstick.
See “Checking the engine oil level and lling with engine oil ”
Start the engine and allow it to run briey.
Stop the engine ,wait one minute and check the oil level . top up if necessary .
