SAFETY INSTRUCTIONS
5. Cutting equipment
This section describes how through correct maintenance and through using the right type of cutting equipment you can:
•Obtain maximum cutting capacity.
•Increase the service life of the cutting equipment.
A. Only use cutting equipment recommended by us! See the ”Technical data” section.
B. Keep the chain cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
C. Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
D.Keep the chain properly tesioned! If the chain is
slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
E. Keep cutting equip- ment well lubricated and properly main- tained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
!WARNING!
Never use a machine with defective safety equipment. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop.
Cutting equipment designed to minimise kickback
!WARNING!
Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback. Use only the bar and chain combinations recommended in the ”Technical data” section.
The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything.
By using cutting equipment with
Guide bar
The smaller the tip radius the smaller the kickback zone and the lower the chance of kickback.
