the throttle (B) half open when cold starting the machine.
S - Pull the throttle lever (B) and stop it at half-throttle put the
ON/OFF switch (A, Fig. 40) in the
lever (B).
T - Put the ON/OFF switch (A, Fig. 41) in the "I" position. Pull

• Place the brush cutter on the ground in a stable position. Check
that the blade is free.
• Holding the brush cutter down, pull the starter rope (Fig. 37)
until the first kick over of the engine is heard (no more than five
(5) pulls). A new unit may require additional pulls.
• Push the choke lever (D) unto the partially closed position, in
an intermediate position (2, Fig.42B). Pull the starter cord to
start the engine. Once the machine is started, warm up the
machine for about few seconds, without touch the throttle
lever. The machine could need more seconds to warm up with
cold weather or at high altitudes. Finally, put the choke lever (D)
unto the all-open position (3, Fig.42C).
• Never wrap the starter cord around your hand.
• When pulling the starter rope, do not use the full extent of the
41 rope as this can cause the rope to break. Do not let starter rope
snap back. Hold the handle and let the rope rewind slowly.
WARNING: Do not cut material with the choke/fast
idle lever at the CLOSE position. Do not operate your
brush cutter with the starting throttle lock engaged.
Cutting with the starting throttle lock engaged does
not permit the operator proper control of the brush
cutter.
NOTE - STARTING WARM ENGINE:
Follow above starting instructions, but do not use the CLOSE
position for start up again.
S model - To start the engine when warm, switch (D) must be
positioned as shown in Fig. 43, page 20.

WARNING: Weather conditions and altitude may
affect carburetion. Do not allow bystanders close to
the brush cutter while adjusting the carburetor.
Keep the engine at full throttle the entire time you are cutting.
NOTE: It is normal for smoke to be emitted from a new
engine during and after first use.

Breaking-in the Engine

The engine reaches the maximum power after 5-8 hours of activity.
42B
During this period of breaking-in do not make the machine
function idly at full throttle, to avoid excessive functioning stress.
CAUTION! – During the breaking-in period do not
vary the carburetion to obtain a presumed power
increment; the engine can be damaged.
Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel by
following the warm engine starting procedure listed above. Ensure
the ON/STOP switch is in the ON position. Starting could require
pulling the starter rope handle many times depending on how
