3. OPERATION

a. Before starting the equipment
The equipment is delivered unassembled. The grass basket and the complete push bar must be
assembled and mounted before using the equipment. Follow the operating instructions step‐ by‐step and
use the pictures provided as a visual guide to easily assemble the equipment.
Fitting the top push bar holder (Fig. 4a)
Position the upper push bar (Fig. 4a / Item 2) such that its holes line up with the holes of the lower bar.
Screw the tubes together, using the screws (Fig. 4a / Item 12) and nuts (Fig. 4a / Item 8) sup‐ plied. Use
the supplied cable clips (Fig. 4b / Item 11) to secure the throttle cable and the engine Start / Stop cable to
the lower push bar.
Fitting the debris box (Fig. 5).
Lift the ejector flap (Fig. 5 / Item 5) with one hand and attach the debris box (Fig. 5/Item 6) to the handle
from above using your other hand.
Important: Before you attach the debris box you must ensure that the engine is switched off and the roller
is not rotating.
The engine does not come with oil in it. Therefore, be sure to add oil before starting the engine. The oil
level in the engine must be checked each time before carrying out any work. Important!
When the engine brake lever is re‐ leased it must return to its initial position and the engine must stop. If
this is not the case, do not use the equipment again.
b. Starting the equipment (Fig. 6 – 7)
In order to avoid any unintentional start‐ups of the engine, it comes equipped with an engine brake (Fig.
6/Item 1) which must be pressed at all times whilst the device is in use, otherwise the engine will stop.
Open the petrol cock (Fig. 7 / Item B). Set the cock to "ON" for this purpose. Set the choke lever (Fig.
7/Item C) to the "Choke" position.
Note: Normally the choke is not required to restart a warm engine. Move the throttle lever (Fig. 1 / Item 7)
to the center position.
Press the engine brake lever (Fig. 6 ) and pull the starter cable (Fig. 7 / Item A) forcefully until the engine
starts.
Allow the engine to warm up briefly and then set the choke lever (Fig. 7 / Item B) to the "RUN" Position.
The speed of the cutter unit can be controlled using the throttle lever (Fig. 6 / Item 7) (tortoise = slow /
rabbit = fast).
Important! Always pull the starter cable slowly until you feel the initial resistance before you then
pull it quickly to start the engine. Do not allow the starter cable to whip back of its own accord.
Important! The scarifier roller begins to rotate as soon as the engine is started.
Never open the ejector flap when the motor is running. A rotating cutting unit can cause injuries.
Always fasten the ejector flap carefully. The flap flips back to the "Closed" position by the tension springs!
