6.1 Starting the engine

• Prime the carburettor by pressing the bulb (30, Fig. O) a number of times.
• Set the switch (10, Fig. C) to the START position.
• Set the choke lever (32, Fig. P) to the CLOSED position.
• Rest the machine on the ground in a stable position, hold firmly and pull the recoil handle (2, Fig. A) slowly upwards until a
certain resistance is felt. Pull the handle sharply a few times until the engine fires and starts. Wait 5-10 seconds, then
squeeze the throttle trigger (12, Fig. C), and the choke lever (32) will return automatically to the OPEN position.
WARNING!
Do not use the choke lever (32) to start the engine when already warm.

6.1.1 Running-in

The engine will begin delivering maximum power after 5-8 hours operation.
Do not operate the engine at full throttle with no load during the running-in period; this will generate excessive mechanical stresses.
WARNING!
Do not adjust the carburettor during the running-in period in an attempt to increase the power output; this could
damage the engine.

6.1.2 Adjusting the carburettor

Before making any adjustment to the carburettor, clean the air filter (28, Fig. M) and warm up the engine.
This engine is designed and manufactured in conformity with European Council Directives 97/68/EC and 2002/88/EC.
WARNING!
Do not tamper with the carburettor.
The idle set screw (31, Fig. P) is set so as to provide an appreciable margin of safety between the idling speed and the speed
at which the clutch engages.
CAUSE
a) No fuel.
b) Lockout switch (10, Fig. C)
positioned on STOP.
c) Spark plug electrode gap incorrect.
Clamp screws (26) loose.
Air filter (28, Fig. M) clogged or damaged.
Fuel filter (36, Fig. S) dirty.
Cylinder fouled.
Insufficient lubrication.
Worn seal.
REMEDY
a) Fill the fuel tank (14, Fig. C).
b) Make sure the switch is positioned
on START.
c) Clean the plug (37) and set the elec-
trodes (38) as illustrated in figure (T).
Tighten the screws (26).
Replace the air filter (28).
Clean or replace the filter (36).
Clean the cooling fins (L).
Unscrew the plug (9) and top up with oil
to the line in the middle of the sight glass
(8, Fig. A).
Have the seal replaced by a maintenance
technician.
