Operating Instructions
Starting the engine
(1) Ensuring the fuel to oil mixture is 25:1, fill up the tank and securely close the lid.
(2) Lay the machine flat on the floor for starting.
(3) Check there are no objects obstructing the head of the machine.
(4) Push the clear rubber fuel window behind the air filter a few times until it is full of
fuel. You should also see the fuel through the clear plastic fuel pipe.
(5) Put the choke into the “on” position ( only for cold engines otherwise leave choke
open )
(6) Half open the throttle.
(7) Push the “On/Off” Switch located on the carry handle of the unit forwards to the
“On” position ( push in the direction of the cutting head ).
(8) Pull the starter handle slowly a few times, and then pull quickly.
(9) If the engine is flooded with fuel, remove spark plug, pull the starter handle
several times, dry plug with a cloth, reinsert and tighten plug, connect spark plug
lead and try again this time turning off the choke.
(10) Run the engine at a slow speed for the first 3 – 5 minutes to allow the engine to
warm up. The engine may begin to splutter, gradually turn off the choke and the
engine will run smoothly.
Notes
-
Don’t accelerate the engine quickly until the engine has warmed up as this will
cause premature wear on the engine.
-
Avoid over-revving the engine as this will damage the engine.
-
Always check the air filter is not dirty or clogged as this will use more fuel and
will reduce the engine performance.

stop the engine.
