Maintenance and servicing
Setting the idling speed
CAUTION!
Set the idling speed when the equipment is warm.
If the engine stalls when the throttle is not pressed and
you have ruled out all the other possible causes listed in
the section 'Malfunction and remedy (FAQ)' on page 39, the
idling speed must be adjusted. To do this turn the idling
speed screw (Fig. 12b/Item P) clockwise until the equipment
runs smoothly at idling speed.
If the idling speed is so fast that the cutting tool turns as well,
it has to be reduced by turning the idling speed screw for as
far as is required for the cutting tool to stop rotating.
NOTICE!
Store the equipment in a dry place and far away from
possible ignition sources such as an oven, a gas-fired
hot water boiler, a gas-fired dryer, etc.
Putting the equipment back into operation
1. Remove the spark plug (see page 45).
2. Quickly tug on the starter line to remove excess oil from the combustion chamber.
3. Clean the spark plug and check that the electrode gap is correct, or insert a new
spark plug with the correct electrode gap.
4. Prepare the equipment for operation.
5. Fill the tank with the relevant mixture of fuel and oil. See the section 'Fuel and oil'
on page 31.
Setting the throttle cable
If the maximum speed of the equipment drops over time and you have ruled out
all the other possible causes listed in the section 'Malfunction and remedy (FAQ)'
on page 39. It may be necessary to adjust the throttle cable.
First of all check whether the carburettor opens fully when the throttle lever is
pressed right through. Remove the air filter cover and the foam air filter prior
to checking this adjustment. This is correct if the lever (Fig. 12a/Item M) touches the
carburettor housing when the throttle is fully open (Fig. 12a).
Figure 12a shows the correct setting. If the lever (Fig. 12a/Item M) does not touch
against the carburettor housing, then it must be adjusted.
The following steps are required to adjust the throttle cable:
You will need a No 2PH cross point screwdriver to adjust the screw, and the supplied
8/10 mm open ended spanner to loosen and then re-tighten the locking nut.
– Undo the lock nut (Fig. 12b/Item N) a few turns.
– Undo the adjusting screw (Fig. 12b/Item O) until the lever (Fig. 12a/Item M) touches fully
against the housing when the throttle is fully activated (Fig. 12a).
– Retighten the lock nut.
