GENERAL SAFETY PRECAUTIONS

10 – English

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.

Guide 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.

Saw chain

•

Saw chain pitch (inches). (The distance between 
three drive links, divided by two.)

•

Drive link width (mm/inches)

!

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 
spark plug cap before you start to work 
on it.
