such as cutting firewood, making fence posts, felling small
trees, limbing, pruning at ground level, and light carpentry.
Cut only wood or wood products with your saw.

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.
