5. Before starting the equipment

1.   Place the engine/gear unit (3) on its left side 

(air filter / carburettor) and then assemble the 
petrol tiller as follows. (Use the spanners 24 & 
25 to tighten / loosen the screws and nuts).

2.  Insert the transport wheel holder in the  
 

mount on the drive unit (see Fig. 4).

3.  Fasten the transport wheel holder with the  
 

help of the screw (19) and the nut (20)  

(see Fig. 5 and 6).

4.   Tension the resetting spring between 

the engine unit and the transport wheel 
holder (2). To do so, first hang the hook of 
the spring (12) in the hole on the inside 
of the gear (3) unit in the hole provided. 
Then fit the eyelet on the spring onto the 
bolt notches on the transport wheel (2). 
Now insert the safety split pin (23) in the 
bolt hole provided on the transport wheel 
to secure the spring and ensure that it 
cannot slip off (Fig. 7-8). 

5.   Insert the depth stop (4) in the opening 

at the back of the gear unit (3) and 
fasten it with the safety split pin (11) at the 
working height you require (3 positions are 
available; when using for the first time we 
would recommend the middle position) 
(Fig. 9-10). 

6.   Stand the petrol tiller upright and feed the 

Bowden wire for the clutch through the lower 
opening in the holder for the steering handles (Fig.11).

7.   Fit the holder for the steering handles (1) 

to the engine unit (3) and fasten with the 
screws (14), the spring washer (17) and 
the washers (16) as shown in Fig.12-14.

8.   Then fit the steering handles through the 

openings on the holder for the steering 
handles (6) on the left hand side and (5) 
on the right hand side and fasten with the 
screws (13), large M6 washers (18) and 
nuts (15) as shown in Fig. 15-16.

9.   Feed the clutch cable through the holder 

for the steering handles and fasten the 
Bowden wire adjuster to the eyelet provided 
on the steering handle by unscrewing the 
upper lock nut and inserting the thread on 
the adjuster through the eyelet. Then attach 
the Bowden wire to the clutch lever (see fig.17).

10. Fit the clutch lever to the left-hand    
 

steering handle and fasten the clutch  

lever to the steering handle with the screw  

(21) and the domed nut (22) 

(see Fig.18 / Fig.18b).

11.  Adjust the cable to the right length with 

the help of the adjuster (see Fig. 17/A) as 
follows: When the clutch lever is pressed 
there must be sufficient tension in the 
V-belt for the star-type tiller blades to turn, 
whereas when the clutch lever is released 
the star-type tiller blades must not move. 
Then tighten the two nuts against each other.  
Ensure that the Clutch Handle Lock 
functions correctly, before starting the 
engine. You should not be able to 
operate the clutch Handle, until the 
Clutch Handle Lock is in the correct 
position. (Fig 18a = stopped. Fig. 18b = 
Blades will rotate).

12. To fit the throttle lever, first unscrew the  
 

screws on the throttle lever. Then attach  

the throttle lever to the right-hand steering  

handle (5) (Fig.19).

13. Fit the cross strut (26) using the screws (21) 

and nuts (15) as shown in Figure 19a. 

Important!

 You must fill up with engine oil 

and fuel before you can start the engine.
