SAFETY INSTRUCTIONS
Specification of blade and chain
When the cutting equipment supplied with your saw becomes worn or damaged you will need to replace it. Use only the type of bar and chain recommended by us.
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

!WARNING!
The risk of kickback is increased with a badly sharpened chain!
A.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, just wood powder.
•A sharp chain eats its way through the wood and produces long, thick cuttings.
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
The bar must be matched to the chain saw design.

•Saw chain pitch (inches)
Spacing between drive links.
•Drive link width (mm/ inches)
•Number of drive links
•Level of kickbak reduction
The level of kickback reduction offered by a chain is indicated by its model number.
•The cutting part of the chain is called the CUTTING LINK and this consists of a
CUTTING TOOTH
(A)and the RAKER LIP
(B). The cutting depth is determined by the difference in height between the two.
•When you sharpen a cutting tooth there are five important factors to remember:
FILING ANGLE
CUTTING ANGLE
FILE POSITION
ROUND FILE DIA- METER
