SAFETY INSTRUCTIONS
•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.
•Saw chain oil hole and hole for chain tensioner pin.
Chain
•Saw chain pitch (inches). (The distance between three drive links, divided by two.)
•Drive link width (mm/inches)
•Number of drive links.
Level of kickback reduction. The only thing that describes the level of kickback reduction offered by a saw chain is its model number.
Sharpening your chain and adjusting raker clearance
WARNING! The risk of kickback is increased
!with a badly sharpened chain!
General information on sharpening cutting teeth
•Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.
•A sharp chain eats its way through the wood and produces long, thick cuttings.
