SAW CHAIN TENSION ADJUSTMENT

Proper tension of the saw chain is extremely important and
must be checked before starting, as well as during, any cut-
ting operation. Taking the time to make needed adjust-
ments to the saw chain will result in improved cutting per-
formance and prolonged chain life.
NOTE: A new chain and bar will need readjustment after as
few as 5 cuts. This is normal during the break-in period,
and the interval between future adjustments will lengthen
quickly (Figure 5).
CAUTION:
will wear more rapidly. Study Figure 4 for infor-
mation concerning correct cold tension (A),
correct warm tension (B), and as a guide for
when saw chain needs adjustment (C).
TO ADJUST SAW CHAIN TENSION:
1. Loosen the bar retaining nuts (D) so they are hand tight.
