5. Press the auto feed spool 

(10) and pull out the 

lines until they reach the 

outside edge of the guard.

6. Replace the spool cover 

ensuring that it is fully 

inserted.

CAUTION.

 After changing 

the line spool, run the 

trimmer under no load for 

at least a minute to make sure that the line and the tool 

are both operating correctly. Use only the line spool as 

recommended by the manufacturer.

Maintenance and cleaning

1. Store the tool, instruction manual and accessories in 

a secure, dry place. In this way you will always have 

the information ready to hand.

2. Keep the tool’s air vents unclogged and clean at 

all times.

3. Remove dust and dirt regularly. Cleaning is best done 

with a rag.

4. All bearings and bushes are lubricated for life.
5.  If the cordset is damaged or worn, it must be replaced 

by the manufacturer, or service agent or a similarly 

qualified person in order to avoid a hazard.

6. Never use caustic agents to clean plastic parts.

CAUTION.

 Do not use cleaning agents to clean the plastic 

parts of the tool. A mild detergent on a damp cloth is 

recommended. Water must never come into contact with 

the tool.

General inspection

Regularly check that all the fixing screws are tight. 

They may vibrate loose over time. 

Storage

1. Store the trimmer away from direct sunlight.
2. Do not store in a nylon bag as this can encourage the 

formation of mould.

3. At the end of the season, give the trimmer an overall 

cleaning and a thorough check.

4. Do not leave the trimmer resting on the floor for 

extended periods as it could cause the shape of the 

guard to alter, posing a safety risk. Hang it off the floor 

by the top handgrip.

Power cord maintenance

If the supply cord needs replacing, the task must be carried 

out by the manufacturer, the manufacturer’s agent, or an 

authorised service centre in order to avoid a safety hazard.
