This article will cover the soft fixes you can take if your hedge trimmer is not idling.
TABLE OF CONTENTS
If the engine is not running at idle speed and cuts out when you release the throttle trigger, then you need to do the following checks:
- Fuel: Make sure it is fresh and correctly mixed (see 'Starting Issues').
- Air filter: Make sure it is clean and unclogged.
- Fuel cap: Make sure it's hand-tight (not too tight or too loose).
- Carburettor: see below.
Carburettor Adjustment - L Screw Focus
It is quite likely that your carburettor settings need adjustment in order for machine to engage in idle speed properly again. This is a procedure which requires a high-level of mechanical skill, so please be wary before trying it. Doing this wrong could make the problem a lot worse. Please contact our helpline if you think you are unable to proceed:
Tools needed: Carburettor adjustment 'pacman' tool
- Get the machine running and warmed up.
- There are 2 adjustment screws on the carburetor, L which refers to low speed, and H which refers to high speed.
- Firstly turn the L screw until the engine ticks over comfortably without the strimmer engaging.
- To adjust the H screw the machine needs to be run on full throttle whilst adjusting the screw.
- The screw should be turned anticlockwise until the machine struggles to rev to max rpm (revolutions per minute), then turned slowly clockwise until the engine picks back up to max RPM.
- This should then be set to go.
Unable to do this Procedure?
If you are unable to do this procedure, then you could order a replacement carburetor, or better still, if you are still under warranty, arrange for your machine to be collected and repaired by our workshop technicians.
