3~4. SAW CHAIN TENSION
ADJUSTMENT
Proper tension of the saw chain is extrem­
ely 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
normal during the break-in period, and the
interval between future adjustments will
lengthen quickly (Figure 3-4A).
CAUTION
If a chain is TOO LOOSE or TOO TIGHT,
the bar chain and saw bearings will wear
more rapidly. Study Figure 3-4A 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:
With no tools system - wear gloves while
tensioning chain.
NOTE: Make sure the CHAIN BRAKE® is
disengaged. Disengage the CHAIN
BRAKE*^^ (D) by pulling it backward (Figure
3-4B),
1. Tensioning the chain is easy. Turn bar
boit knob (E) counter clock wise. Then
turn ring (F) counter clock wise to
loosen chain or clock wise to tighten
chain, (Fig, 3-4C)
2. 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,
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 as
described in step 1,
3. While tensioning the chain. Hold tip of
the bar up and then tighten the bar bolt
knob (E).

3-5. FILLING OIL TANK
Using a funne!, fill oil tank with Genuine
Factory Parts Chain, Bar and Sprocket oil.
Wipe up any spills. Make sure no dirt gets
into the oil tank.
The saw chain requires lubrication while in
use to minimize friction with the guide bar.
The oi! tank holds 4.5 ozs of oli, enough to
lubricate the chain for 12-15 minutes of
sawing.
We recommend using Genuine Factory
Parts Chain, Bar and Sprocket Oil, which
contains additives to reduce friction
wear and reduce resin residue formations.
CAUTION
The oil tank level should be frequently
checked during operation to avoid starving
the bar and chain of lubrication.
NOTE: Your chain saw is equipped with an
Automatic Oiler system and is the ONLY
source of lubrication for the bar
and chain (Figure 3-5A).
