GENERAL SAFETY PRECAUTIONS

WARNING: Always stop the en- gine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the lead from the spark plug before you start to work on it.

WARNING: Using an incorrect cutting attachment or an incorrect- ly sharpened blade increases the risk of kickback.

Cutting equipment

Grass blades and grass cutters are in- tended for cutting coarse grass.

A trimmer head is intended for trimming grass.

General rules

Only use cutting attachments with the guards we recommend! See the section on Technical data.

Keep the teeth of the blade correctly sharp- ened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents.

Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.

Sharpening grass cutters and grass blades

S See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single--cut flat file.

S Sharpen all edges equally to maintain the balance of the blade.

WARNING: Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be re- used. Only use original blades of the specified type.

Trimmer head

IMPORTANT!

Always ensure the trimmer line is wound tightly and evenly around the drum, other- wise the machine will generate harmful vibration.

SOnly use the recommended cutting at- tachments. See the section on “Technical data”.

SSmaller machines generally require small trimmer heads and vice versa. This is be- cause when clearing using trimmer line the engine must throw out the trimmer line radially from the trimmer head and overcome the resistance of the grass being cleared.

SThe length of the trimmer line is also im- portant. A longer trimmer line requires

greater engine power than a shorter trimmer line of the same diameter.

SMake sure that the cutter on the trimmer

guard is intact. This is used to cut the trimmer line to the correct length.

STo increase the life of the trimmer line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer.
