1. If you do cutting on well-kept surfaces without terrain irregularities, the mower can be
pushed without lifting the machine front and with the support plate sliding on the
stubble. Be prepared, however, that the forward motion will not be ideally even. Any
unexpected bump can swerve the mower from straight direction.
2. If there are some bumps on the surface such as molehills or natural terrain irregularities,
it is advised to slightly lift the machine front by mildly pushing down on handlebars
handles while pushing the mower forward.
5.6.3 Cutting procedure.
Set the engine on maximum speed, let the mowing disk rotate at maximum speed
(see chapter 5.3) and get the machine into motion (see chapter 5.6.2) against the sward to be
cut. Mown grass is thrown away by the mowing disk to the right side onto the apron, which
forms a swath.
If the stand is very dense, grown through, rotten or lodged, the machine working
width must be reduced accordingly so that the mowing disk rotations are not being
excessively reduced and the cutting quality impaired.
5.6.4 Problems at cutting.
Choking of the space under the lower casing with grass shows as follows:
a) Engine markedly loosing speed but not stalling: stop the machine without delay while
slightly lifting the machine front (by pushing down on the handlebar handrails). The
space under the lower casing will do itself a partial clearance of excessive grass. Then
drive the machine against the sward again (see chapter 5.6.2).
,
Be very careful while driving with the machine backwards!
b) Engine loosing speed and stalling: release the control bar of the mowing disk drive
clutch on handlebars, lift the machine front (by pushing down on the handlebars) and
drive a bit back. Clear the space under the lower casing and spread the cut grass across
the ground. Start the engine, switch on the mowing disk drive (see chapter 5.3) and once
again drive the machine against the grass stand (see chapter 5.6.2).
,
The engine must be always switched off when clearing the space under the lower
casing!
,
Tilt the machine always only backwards onto the handlebars. Be always very
careful while moving in the space under the lifted machine! Secure the machine
against motion!
,
Be very careful while cleaning the space under the lower casing. Cutting edges of
the blades are sharp. You should be wearing protective gloves or you can also use a
suitable piece of branch etc.
