SAFETY INSTRUCTIONS

Cutting equipment

IMPORTANT INFORMATION

The section describes how through correct mainte- nance and through using the right type of cutting equipment you can reduce the machine‘s tendency to kickback, obtain maximum clearing capacity and increase the service life of the cutting equipment.

Only use the cutting and guard equipment we recommend! See chapter “Technical data“.

Refer to the instructions for the cutting equipment for the correct winding of cord and for the selection of the right cord diameter.

Keep the blade’s teeht well and correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.

Maintain the correct setting. Follow our instruc- tions and use the recommended filing gauge.

!WARNING!

Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback.

Sharpening the clearing blade

• 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.

Sharpening the grass blade

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.

Trimmer head

• Only use a trimmer head and trimmer cord that is recommended. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the cutting equipment we recommend! See chapter “Technical data“.

Generally smaller machines require a small trimmer head and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and also meet resistance from the grass being cleared.

The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.

Make sure the knife positioned on the trimmer guard is intact. This is used to cut the cord to the correct length.

To increase the life of the cord it can be soaked in water for a few days. This will make the line tougher and it will keep longer.

IMPORTANT INFORMATION

Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise harmful vibrations will occur.

!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.
