If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary. NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston. Filing the grass blade ! ! WARNING! Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it. • See the cutting equipment’s packaging for correct filing instructions. • The blades are sharpened using a single cut flat file. • Sharpen all edges equally to maintain the balance of the blade. ! ! WARNING! Always discard a blade that is bent, twisted, cracked, shattered or damaged in any other way. Never attempt to straighten a twisted blade for use again. Only use original blades of the prescribed type. English – 27 MAINTENANCE Sharpening the clearing blade ! ! WARNING! Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback. • See the cutting equipment’s packaging for correct filing instructions. • A correctly sharpened blade is a prerequisite for working efficiently and to avoid unnecessary wear to the blade and clearing saw. • Make sure that the blade is well supported when you use the file. Use a 5.5 mm round file with a file holder. • The sharpening angle is 15°. Every other tooth is sharpened to the right and the intermediate tooth to the left. When the blade has been heavily pitted by stones the upper side of the teeth can, in exceptional cases, need to be dressed using a flat file. In such cases this takes place before sharpening with the round file. Dressing the top side must be carried out equally for all teeth. • Adjust the setting. This should be 1 mm. Maintenance schedule Below follows some general maintenance instructions. If you need further information please contact your service workshop. Daily maintenance 1.Clean the outside of the machine. 2.Make sure the harness is not damaged. 3.Make sure the throttle trigger lock and the throttle function correctly from a safety point of view. 4.Check that the stop switch functions. 5.Check that the cutting head does not rotate while idling. 6.Clean the air filter. Replace if necessary. 7.Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked. 8.Check that the blade is well centred, is sharp, and is not cracked. An uncentred blade causes vibrations that can result in damage to the machine. 9.Check that the trimmer head is undamaged and not cracked. Replace the trimmer head if necessary. 10.Check that the locking nut is tight. 11.Check that the blade‘s transport guard is intact and that it can be secured correctly. 12.Check that all nuts and screws are tightened. 1 2 4 3 6 7 8 11 9 5 10 12 28 – English MAINTENANCE Weekly maintenance 1.Check the starter, the starter cord and the return spring. 2.Make sure that the vibration damping elements are not damaged. 3.Clean the outside of the spark plug. Remove and check the electrode gap. Adjust the gap to 0.5 mm or change the spark plug. 4.Clean the cooling fins on the flywheel. 5.Clean or replace the muffler’s spark arrest screen (not on mufflers with a catalytic converter). 6.Clean the carburettor area. 7.Clean the cooling fins on the cylinder and check that the air intake in the starter unit is not blocked. 8.Check that the angle gear is 3/4 filled with grease. Fill if necessary using special grease. 3 1 2 4 0,5 mm 5 6 7 8 Monthly maintenance 1.Clean the fuel tank. 2.Clean the carburettor and the area surrounding it. 3.Clean the fan and the area around it. 4.Check the fuel filter and the fuel pipe, replace if necessary. 5.Check all cables and connections. 6.Check the clutch, clutch springs and the clutch drum with regard to wear.
