G.ENGINE/SHAFTASSEMBLY

A

DANGER. Do not run engine without shaft attached as clutch could fly off.

1) Insert the shaft (A) into the engine joint (B) making the female squared end (C) inside the joint mates with the male squared end (D) of the shaft.

Rotate the shaft from right to left to obtain a precise fit. Now tighten the locking bolt (E) clockwise to ensure the shaft is held firmly in the joint.

2)If the joint is not tightened onto the engine housing, first make sure the shaft is fully and correctly engaged up to the shank, then tighten the 4 screws (A) in a criss-cross sequence.

3) Assemble the eyelet (A) of the ground wire onto the end of the throttle cable and install the washer (B).

Insert the throttle cable into the cable mount

(C), install the second washer (B) and insert the hexagonal nut.

4)Fit the end of the trigger cable connector (B) into the slot on swivel (C).

5)Adjust the nut (D) of the trigger cable connector so that the cable can easily slide in the opening with a play of 1 mm before operating the swivel (C).

Tighten now the hexagonal nut (E).

6)Stop switch (STOP) cable: fit the connection.

H.HANDLEASSEMBLY

J FRONT HANDLE

Secure the handle in front of the label placed on the shaft 11 cm from the rear grip when assembling nylon string head and 36 cm when

assembling metallic blades. This position ensures optimum balance and safety. The handle must be perpendicular to the shaft as illustrated.

6)ENGINE STOPPING

Press the stop switch moving it to STOP position 0.

WARNING: when the engine is switched off rotating parts, blade or nylon string head, will keep on rotating for a few seconds. Hold the machine until all parts come to a standstill.

N.B. In an emergency the above mentioned delay in stopping may be shortened by touching blade parallel on the ground.

L.CARBURETTORADJUSTMENT

Your machine may be fitted with a highly sensitive low emission carburettor. We now therefore recommend that carburettor adjustments are only made by an authorised servicing dealer, equipped with instruments that will ensure best performance with lowest emission levels.

To adjust the idle speed, however, proceed as follows:

With engine running and warm, slowly turn screw ‘I’ or ‘T’ clockwise until the engine runs smoothly with a consistent noise level but without making the chain or cutting head rotate.

If the cutting attachment does move or the engine
