3-5. SAW CHAIN TENSION
ADJUSTMENT
Proper tension of the saw chain is extr­
emely important and must be checked
before starting, as well as during, any
cutting operation. Taking the time to
make needed adjustments to the saw
chain will result in improved cutting
performance and prolonged chain life.
NOTE: A new chain and bar will need
readjustment after as few as 5 cuts.
This is norma! during the break-in
period, and the interval between future
adjustments will lengthen quickly
(Figure 3-5A),
CAUTION
It 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
co!d tension (A), correct warm tension
(B), and as a guide tor when saw chain
needs adjustment (C).
TO ADJUST SAW CHAIN
TENSION:
1. Loosen the bar retaining nuts (D) so
they are hand tight. (See Fig.3-5B)
2. Holding the nose of the bar up, use
the screwdriver or scrench if
provided in your User’s Kit to turn
the guide bar adjustment screw (E)
(Fig.3-5C) clockwise to tighten the
chain.Turning the screw COUNTER­
CLOCKWISE LOOSENS THE
CHAIN on the guide bar.
3. After adjustment and while wearing
heavy duty work gloves, move the
saw chain back and forth on the
guide bar to be sure the chain
moves freely and is in proper mesh
with sprocket.Do not move chain
with bare hands.
NOTE:IF the chain is difficult to rotate
or if it binds on the guide bar, too much
tension has been applied and must be
adjusted.To decrease tension, turn the
adjustment screw counterclockwise
slowly.Move the chain back and forth
until it moves freely.

Holding the nose in upper position,
securely tighten the bar retaining
