Loosen the two handle bar pivot bolts (A) (where fitted) (Fig.2).
Fold the handle bars out straight, in line with the lower handle

bars. Tighten the two handle bar pivot bolts (Fig. 2) (A) then the cam
locks (B) (Fig.1) to secure the handle bars in position.

Remove and discard the white protective packing sheet from

the mower.

Engine oil

engine will occur. 

Refer to the engine owner’s manual.

The 4 stroke engine fitted to the lawn mower

is shipped with no oil

in the sump. 

Engine fuel

OPERATION - All mowers

Adjusting the cut height –

 

refer figure 3.

The lawnmower has ten height settings controlled by the 

height adjustment lever located at the rear right hand 

wheel.  

Grasp the height adjustment lever (1) and pull the

lever away from the base to disengage the lever from the

height adjustment rack (2).

Move the lever either forwards or backwards to the

desired position and release the lever so as to engage in

the  height adjustment rack.

To adjust the clutch spring stretch rotate

the thumb wheel (A) on the cable support

block (one click at a time).

To increase the stretch rotate the thumb

wheel (A) in an anti-clockwise direction.

To decrease the stretch rotate the thumb

wheel (A) in a clockwise direction.

Refer to figure 17.

Check that the clutch disengages by pulling the

mower backwards (with the clutch engagement

lever released) - the rear wheels should free wheel.

If not do not attempt to start the mower as it may

drive off unattended.

If the mower free wheels test the mower at all

engine speeds ensuring that it self-disengages

when the drive clutch engagement lever is released.

If you still experience problems, please contact
