MAINTENANCE

**** Danger – Rotating blades.
Wait until all rotating parts have stopped and the appliance has cooled down.
Switch the engine off and remove the socket plug before any work on the engine. Wait until all rotating parts have stopped and the appliance has cooled down.
Keep the appliance, especially the tank and engine, clean at all times. Clean the ejection opening and cover at regular intervals.
Regularly remove any remainders of grass and weed to avoid an overheating of the shaft tube. Remainders of grass and weeds get caught under the protection cover avoiding a sufficient cooling of the shaft tube. Remove the remainders carefully with a screwdriver or a similar tool.
To reduce fire risks, periodically clean the cylinder flaps with compressed air and clear the silencer area to get rid of sawdust, branches, leaves or other debris.
To keep the danger of fire as low as possible the engine and exhaust pipe must be free from grass, leaves and excess grease.
