F. Fuel supply problems
The petrol from the fuel tank is pumped to the carburettor by a small vacuum pump. There is
a fuel fi lter in this petrol line that will stop dirt from reaching the carburettor. This fi lter can
become obstructed in due course and must then be replaced.
• Check the fuel fi lter (read the procedure in the
engine manual).
• Dirt can accumulate in a narrowing in the petrol
line. Disconnect the line from the fuel fi lter and
blow it out using compressed air.
• Verify that there is not an accumulation of dirt
in the fuel tank. Remove the dirt by discharging
the petrol by using the drainage plug.
G. Poor combustion
Since the engine is the power source, it has the greatest infl uence on performance. The
optimal functioning of the engine can only be guaranteed when combustion is good. Check
whether the throttle valve closes automatically while operational due to vibrations or a lack of
maintenance. This will bring too much petrol into the engine and, therefore, combustion will
be incomplete.
This can be checked during your regular visit to an authorized ELIET dealer or an engine service
centre. Request that the following be performed when it is again put in for a service:
• An overhaul of the carburettor
• A check of the ignition
• Post-measuring and adjustment the valve clearance
Warning:
A poor combustion in the engine will lead to after-burning in the exhaust. This
increased exhaust temperature can seriously damage the catalyst. Such damage
and consequential damage to the engine are not covered by the Guarantee.
9.7.3 Problem with the ABM system
The ABM system will ensure that the feeding is interrupted if the engine falls below a critical speed
(2,750 rpm). The feeding will be restarted when the engine is again reaches a set speed (2,800
rpm). This stopping and starting of the feed system (roller and belt) takes place through a solenoid
valve that will or will not close the supply of the hydraulic oil. Thee phenomena can occur:
1. The feed roller and feed belt continuously run independently from the speed of the engine.
2. The ABM system is activated due to a deviating speed.
3. The roller and belt no longer run at the feed position.
ELIET recommends with regard to all three situations that you contact an authorized ELIET dealer.
