Assembling the lawn mower

Take the lawn mower and attachments out of the
packaging and check that all parts are there (Fig. B).
Fasten the lower push bar (Fig. B/5) to the mounts
on the mower housing as follows. When doing so,
make sure that the tension cables, which are to be
fastened later, are not in the way. Remove the two
locking cotter pins from the chute flap shaft (Fig.
A/8). Slacken the two hand locking screws on the
engine housing. Pull the lower push bar apart. Fit it
onto the shaft so that it locks into the holders on the
engine housing, and the hand locking screw with the
start tension cable guide (Fig. A/6, at the top of the
push bar) is attached on the right in the pushing
direction. Fit the two locking cotter pins again. If the
hole is not easy to get to, start at the other side.
Then press sideways on the side that has been
locked in order to move the shaft a little. Then screw
the lower push bar tightly in position with the hand
locking screws. Now screw the upper push bar (Fig.
B/2) to the lower push bar. Make sure that the start
tension cable guide on the right-hand side faces
inwards (Fig. C). Then draw both tension cables
underneath the crossbar of the lower push bar (see
Fig. F). Fasten the tension cables for the engine
control and engine brake (Fig. D) in such a way that
the lever for the engine control faces outwards and
the tension cable holder for the engine brake faces
inwards. Fasten the screw and the nut tightly
(wrench size 10). Then lift the lever for the engine
brake out of the fastening hole on the left-hand side
and pull it slightly forwards with your left hand (Fig.
E). Then insert the tension cable for the engine brake
in such a way that it is inserted in the lever from the
outside (Fig. E/1). Secure the tension cables with a
cable binder (Fig. F) and cut off the excess length
with a cutter.
Checking the setting of the engine brake
Fasten the lever for the engine brake on the upper
push bar (Fig. G) with adhesive tape. You should be
able to pull the lever for the engine brake smoothly
as far as the handle. If this is not the case (the
distance between the lever for the engine brake and
the upper push bar is greater than approx. 5mm),
check whether setting of the engine brake is correct
(12. Care and maintenance, Item 5). Remove the
adhesive tape when you have finished checking the
setting and have adjusted it if required.
Assembly of the grass basket
Place the frame for the grass basket on the ground
with the handle in the middle facing upwards (Fig. H).
Then place the basket behind the frame with the

hard plastic base facing downwards. Draw the grass
basket over the frame such that the top side of the
basket stretches over the back part of the frame and
the hard plastic base hangs down. Then clamp the
grass basket with the plastic bars on the frame.
Lift the chute flap with one hand and attach the
assembled grass basket over the chute flap shaft
(Fig. I)

5. Setting the cutting height

Important! Adjust the cutting height only when
the engine is switched off and the plug boot has
been pulled.
Before you begin to mow, check to ensure that the
blade is not blunt and that none of the fasteners are
damaged. To prevent any imbalance, replace blunt
and/or damaged blades as a set only (if applicable).
To carry out this check, first switch off the engine and
pull the spark plug boot.
The cutting height is centrally adjusted with the
cutting height adjustor lever
(Fig. B 9). Up to 5 different cutting heights can be
selected.
Pull the adjustor lever out and select the desired
cutting height. The lever snaps into the desired
position.
6. Starting up
Important!
The engine does not come with oil in it.
Therefore, ensure that you add 0.4 liters of oil
before starting it up. Use normal, multigrade oil
(15W 40). The oil level in the engine must be
checked each time before mowing. (see
Checking the oil level).
In order to avoid any undesired start-ups of the
lawn mower, this model is equipped with an
engine brake (Fig. J item 1+2) that must be pulled
back before the engine can be started. When the
engine brake is released it must return to the
starting position and the engine will stop
automatically.
Before you start the lawn mower, open the petrol
stopcock (Fig. K, arrow = Petrol stopcock open).
Move the speed lever (Fig. L) to the choke
position. Pull the engine brake lever together (Fig.
J item 2) and give the start tension cable a strong
pull. You can control the rotation speed of the
blade using the speed lever (Fig. L).
