5.7.3 Sward cutting
Set the engine on the maximum speed, let the cutting blade rotate at the maximum
speed and then get the machine into motion, facing the to-be-cut sward.
At cutting, you should proceed only in such a way that the to-be-cut sward is – if
possible – on the left side of the machine. When cutting on slopes, it is advised to drive the
machine along the slope contours. Watch a maximum permissible long-term machine
inclination of 20° (30° over a short-term – up to 30 sec)!
If the cut stand is very dense, grown through, rotten from below or lodged, the
machine working width must be accordingly reduced, higher cutting height adjusted or
machine travel speed reduced so that the cutting blade rotations are not excessively slowed-
down, which would result in the impaired cutting quality and engine overloading.
5.7.4 Problems at cutting
Choking of the space under the cutting blade cover with the grass biomass shows in:
a) Engine markedly losing speed but not stalling : machine travel to be switched off
immediately (lever on the left handrail grip), shift in reverse gear (R), the machine
front to be slightly lifted by pushing down on handrails and move the machine slightly
back. The space under the cutting blade cover will do itself a partial clearance from
excessive grass. Then drive the machine against the sward again.
b)
Engine losing rotations and stalling
: release both levers on the handlebars, start the
engine, shift in reverse gear and back with the machine out from the sward to be cut.
Switch off the engine. Clean the space under the cutting blade space and spread the cut
grass across the ground surface. Start the engine, switch on the cutting blade drive and
drive the machine against the sward again.

Be very careful while lifting the machine and driving on reverse gear!

Tilt the machine always only backwards onto the handlebars. Be very careful while
moving under the lifted machine! Secure the machine against its spontaneous
motion and tilt!

Be very careful while cleaning the space under the cutting blade cover. Cutting
edges of the blades are sharp. You should wear protective gloves or use a suitable
piece of branch etc.
5.7.5 Cutting on slopes

If possible, do not use the machine on wet grass. Remember that the terrain you are
moving on must always be safe. Walk (never run) at work. Be careful especially
when changing the machine direction on slopes. Do not cut grass on steep slopes.
When accidentally falling, immediately release your hold on the machine.

The safe slope accessibility of the machine is 10°.
For a better steering control of the machine secure the leading wheels with locking pins
in straight direction. The pins are included in machine accessories. If not to be used, they
should be folded between lugs on the handrail tube. Use medium or minimum travel speed.
For cutting on slopes up to 20° it is recommended to drive the machine along the
contour. It is the safest movement on the slope. It is also possible to make use of the side
adjustment of handlebars.
On slopes between 20° and 30° never drive the machine in the downhill direction for a
long time. Engine oil filling level moves out of sucking points and the engine oiling is
insufficient.
