3-6. SELECTING THE PROPER EXTENSION CORD FOR YOUR SAW MODEL
1.
The extension cord is to be a type acceptable for outdoor use, marked with the suffix W or W-A following the cord type
designation, for example - SJTW or SJTW-A.
2.
Make sure the extension cord is in good condition before using.
3.
Keep the cord away from the cutting area and to position cord so that it will not be caught on branches, and the like, dur-
ing cutting.

3-4. 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 3-4A).
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
information 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 bolt 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 funnel, 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 oil tank holds 4.5 ozs of oil,
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 fric-
tion 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).
