GENERAL SAFETY PRECAUTIONS
Cutting equipment
This section describes how you can achieve maximum clearing capacity and extend the life of the cutting attachment through correct maintenance and using the right type of cutting attachment.
•Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.
•Only use cutting equipment recommended by us!
•Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
•Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
•Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
•Keep 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! Never use a machine with faulty
!safety equipment. The machine’s safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.
WARNING! Always stop the engine before
!doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it.
Specification of bar and saw chain
When the cutting attachment supplied with your machine has to be replaced, because it is worn out or damaged, you must only fit the types of bar and saw chain recommended by us.
Bar
•Length (inches/cm)
•Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.
•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.
•Lubrication hole and hole for the chain tensioner.
