12. CHAIN AND GUIDE MAINTENANCE

Chain
CAUTION To ensure safe and faultless saw operation, it is required that the chain should be
sharp at all times.
Chain sharpening rules:
CAUTION! Wear protective gloves
Before sharpening:
Apply the file to the cutting link and push directly forward. Keep the file in the position as
shown. (fig. 34) After sharpening of each link, check the depth using a feeler gauge; file down
to adjust as shown if necessary. (fig. 35).
CAUTION! The front edge must be round in order to reduce the risk of kickback or clamping
inside the section.
Suitable feeler gauge (1) (fig. 35)
Feeler gauge reference level (2) (fig. 35)
Link/edge standard depth (3) (fig. 35)
Each cutting link must have equal length and edge bevels as shown. (fig. 37)

Chain guide

Turn the chain guide over from time to time to prevent unilateral wear.
The bar groove must be rectangular at all times. Check the bar groove for wear. To check,
apply a ruler to the bar and the outer edge of the cutting links. If there is a gap between them,
the bar is OK. Otherwise, the bar is worn. This means the bar needs a repair or a replacement.
