until tang is to the end of its travel.
4.
Loop saw chain over drive sprocket with the cutting

3-5. 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 quick-
ly (Figure 3-5A).
CAUTION
If a chain is TOO LOOSE or TOO TIGHT, the bar chain and
saw bearings will wear more rapidly. Study Figure 3-5A for
information concerning correct cold tension (A), correct
warm tension (B), and as a guide for when saw chain
needs adjustment (C).
