ENGLISH
8.3 Adjusting the trimmer line
Feed out thetrimmer line like this:
1. Run theengine at full speed whilst carrying out points 2–4.
2. Tap thetrimmer head on theground and lift it up again.
3. The line will be fed out automatically.
4. The line will be cut to thecorrect length by thecutter under thetrimmer guard.
5. Switch off theengine and using something like ascrewdriver, clean off any grass and debris from around
the guard and trimmer head, otherwise it could impair thecooling of thedrive shaft.
8.4 Using the 4-tooth brush cutter blade
Use only thesupplied 4-tooth brush cutter blade or anidentical replacement. A saw-toothed clearing
saw blade must not be used.
The 4-tooth blade can be tilted to various angles for cutting brush from around tree trunks.
!
• Normal use: Use thearc of theblade cutting
circle labelled “A” for normal brush cutting.
• The arc labelled “B” can also be used if
thehandles are held firmly.
• Caution! Never use theblade within arc “C”,
as uncontrolled kickback could occur which
could injure any bystanders or animals within
thedanger zone.
9. Maintenance
Warning: Disconnect thesparkplug lead before carrying out any maintenance.
• Lubricate thepivot after every 25 hours of use:
1. Loosen thehead of thebolt on theside of thegearbox and smear thepivot with some high
temperature grease.
2. Wipe off any excess grease.
3. Tighten thebolt.
• Clean thecooling fins regularly, so theengine is properly cooled.
