ling to start mowing.
Working Advices
1. Walk, never run with the mower, be very care-
ful when mowing uneven or rough ground.
2. Mow across slopes, never up and down.
3. Be careful when changing the direction of the
mower on a slope.
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 cut-
ting height for the first cut of the season or in
drought conditions.
7. Only about one thirds of the grass height
should be cut.
8. When mowing with mulching, to ensure that
the cut grass can be scattered efficiently, do not
cut high or wet grass. When you have been cut-
ting for several minutes, please stop the mower,
and clean the blade and the deck.
9. 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
As soon as grass clippings start to trail the lawn
mower, it is time to empty the grass bag.
IMPORTANT: Before taking off the grass bag,
switch off the engine and wait until the blade
has come to a stop.
1. To take off the grass bag, use one hand to lift
up ejector flap and the other to grab onto the
carry handle. The ejector flap automatically falls
down after removing the grass bag and closes
off the rear chute opening.
2. Empty the grass debris in the grass bag, and
refit grass Bag.
IMPORTANT: If any grass residue is caught in
the discharge chute, clean it using a brush .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. To
ensure that the cut grass can be collected into
grass Bag, the discharge opening and inside the
mower casing must be cleared of any blockage.
