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.
!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.
1Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.
2Only use cutting equipment recommended by us! See the ”Technical data” section.
3Keep 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.
4Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
5Keep 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.
6Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
!WARNING!
Always stop the engine before carrying out any work on the cutting equipment. This will continue to move even after the throttle has been released. Make sure the cutting equipment has stopped completely and disconnect the HT lead from the spark plug before you start work on it.
Specification of blade and chain
When the cutting equipment supplied with your machine becomes worn or damaged, you will need to replace it. Use only the manufacturer approved bar and chain.
Guide bar
• Length (inches/cm)
• Number of teeth on bar tip sprocket (T).
Small number = small tip radius =
• Chain pitch (inches) The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.
• Number of drive links The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.
• Bar groove width (inches/ mm)
The groove in the bar must match the width of
the chain drive links.
• Saw chain oil hole and hole for chain tensioner
