Throttle lock, throttle trigger and return
spring – removal
1
Remove the throttle lock by pressing it to the left
(A) and carefully levering it up with a screwdriver
on the clutch side (B) of the saw to disengage the
lugs on either side of the throttle lock from the fuel
tank. When both lugs are clear of the tank, pull the
lock backwards (C).
Drive out the steel pin using a 2.5 mm/0.1" diam-
eter drift (A). Push it out from the flywheel side of
the saw. Remove the throttle trigger by first press-
ing it towards the clutch side of the saw (B) until it
clicks, then towards the flywheel side until it clicks
again. Remove it from the tank and lift out the
return spring.

Choke control – refitting
First reattach the choke control to the air filter, then
press it onto the carburettor so that the clips engage.
Then refit:
• stop switch
• carburettor into its rubber mountings
• throttle pushrod into the fuel tank and connect to
throttle lever.
• lift the spring arm over the throttle pushrod
• fuel hose to the carburettor
• air filter and cylinder cover
Refit the return spring to the throttle trigger as
shown. Make sure the spring is correctly positioned
by engaging one end in the slot in the throttle
trigger (A).

First insert the rear edge of the throttle trigger into
the tank. Then push/clip the front edge into the two
clips on the tank with the aid of a combination tool,
for example. Drive in the steel pin from the clutch
side. Use a 2.5 mm/0.1" diameter drift.
3
Then press down the return spring while pressing
the throttle lock forwards/upwards into the retaining
clip in the fuel tank until you hear a click. Release
the return spring in the throttle lock, then press the
lock down onto the tank.

Check the operation of the throttle lock by trying to
press the throttle trigger without pressing down the
throttle lock. Also check that the throttle lock and
throttle trigger return freely to their original posi-
tions when released.
