C. CHAIN TENSION
• Chain tension is very important -
- A loose chain will wear the bar and itself.
- A loose chain can jump off bar while you are cut-
- A tight chain can break or damage the saw and/or
har.
• The chain stretches during use, especially when
new. Check tension periodically as follows:
- each time the saw is used;
- more frequently when the chain is new;
- as the chain warms up to normal operating temper-
• Chain tension is correct when the chain will move
freely around the bar and chain does not sag beneath
the guide bar.
• Chain tensioning procedure.
[CAUTION;
I
Always wear gloves when handling the
chain. The chain is sharp and can cut you even when
it is not moving!
1. Loosen bar clamp nuts.
2. Lift up the tip of the guide bar and turn the adjusting
screw clockwise until the chain does not sag beneath
the guide bar. Figure 13. .
'
3. While lifting the tip of the guide bar, tighten the bar
clamp nuts with the scrench.
4. Make sure the chain rotates freely around the bar.
D. BAR AND CHAIN OIL
• The Guide Bar and Cutting Chain require contin­
uous lubrication to remain in operating condition.
Lubrication is provided by the automatic oiler system
when the oil tank is kept filled.
- Lack of oil will quickly ruin the Bar and Chain.
- Too little oil will cause overheating shown by
smoke coming from the chain and/or discoloration
of the guide bar rails.
• Genuine POULAN/POULAN PRO Bar and Chain
Oil is recommended to protect your unit against
excessive wear from heat and friction. POULAN/
POULAN PRO oil resists high temperature thinning.
If POULAN/POULAN PRO Bar and Chain Oil is not
available, use a good grade SAE 30 oil. Never use
wa.ste oil for bar and chain lubrication.
• In freezing weather oil will thicken, making it nec­
essary to thin bar and chain oil with a small
amount of #1 Diesel Fuel or kerosene. Bar and
chain oil must be free flowing for the oil system to
pump enough oil for adequate lubrication.
1. USE THE FOLLOWING:
30° or above - 100% lubricant - undiluted.
30° - 0° F -
95% lubricant to 5% #1 Diesel Fuel or
kerosene.
Below 0°F- 90% lubricant to 10% #1 Die.sel Fuel
or kerosene.
2. HOW TO FILL THE OIL TANK
a. Stop the engine.
b. Turn the saw on its side with oil cap up. See oil cap
location. Figure 15.
c. Loosen cap slowly and remove.
d.
Fill the oil tank.
e. Replace the oil cap securely.
3. USING THE OILER
Your saw is equipped with an automatic oiler.
• The automatic oiler supplies lubrication to the bar
and chain at all times while the engine is running.
