Tensioning The Chain - Poulan Pro PL914 Instruction Manual

VIBRATION EXPOSURE
Exposure to vibrations through prolonged use of power
tools could cause blood vessel or nerve damage in the
disorders or abnormal swelling. Prolonged use in cold
weather has been linked to blood vessel damage in
otherwise healthy people. If symptoms occur such as
a WARNING! Do not connect the power tool to the
power supply before it is completely assembled.
a WARNING! Always use gloves when handling the
chain.
ASSEMBLING THE GUIDE BAR AND CHAIN
Unpack all parts carefully and place the power tool on a
solid, level surface. Examine the power tool for damage.
Use the supplied combination tool (22) to loosen and
remove the lock nut (5), then remove the sprocket cover
(6). The chain tensioning bolt (19) must be aligned
with the corresponding hole in the guide bar (7, D). If
necessary, use the combination tool to turn the chain
tensioning screw (16) until the chain tensioning bolt is in
the proper position.
The running direction is marked with an arrow on the
sprocket cover (G). To determine the direction of cut, it
may be necessary to turn over the chain (4). Hold the
guide bar (7) vertically with the tip pointing upwards and
install the chain, beginning at the tip of the bar.
Place the guide bar with the chain on the guide bolt (18)
and chain tensioning bolt.
Place the chain around the chain sprocket (17) and make
sure it is correctly mounted (A).
Place the sprocket cover on top and tighten gently with the
lock nut using the combination tool.

TENSIONING THE CHAIN

a WARNING: Unplug the chain saw from the power
source before adjusting the chain tension.
Make sure the chain is inside the guide groove of the
guide bar.
Using the combination tool, turn the chain tensioning
screw clockwise. Pull upwards on the tip of the guide bar
while the chain is being tensioned.
Do not tension the chain too tightly. When cold, it should
be possible to lift the chain in the middle of the guide bar
approximately 5 mm (0.2 in). Tighten the lock nut securely.
A new chain requires a running-in period of approximately
5 minutes. Chain lubrication is very important at this stage.
After running-in, check the chain tension and adjust if it is
necessary.
NOTE: A new chain will stretch. Check the chain
the chain becomes loose around the guide bar.
When warm, the chain will expand and slacken and there
is a danger of it jumping off the rail.
Tension the chain when it is necessary. If the chain is
tensioned when hot, it must be loosened again when
the sawing work has been completed. Otherwise, the

contraction which takes place as the chain cools can
result in excessively high tension.
ADDING GUIDE BAR AND CHAIN OIL
a
operate the chain saw without oil or at an empty oil
tank level, as this will damage the product.
a CAUTION: It is important to use only standard
guide bar and chain oil to avoid damage to the
chain saw. This type of oil can be found at the
location you purchased the chain saw or your
local hardware store. Never use recycled or old
oil. The use of non-approved oil will invalidate the
warranty.
Filling the oil tank:
1. Set the chain saw on any level surface with the oil tank
cap (14) facing upward.
2. Clean the area around the oil tank cap with a cloth and
unscrew the cap by turning it counterclockwise.
3. Pour oil into the oil tank opening (20) until the reservoir
is full. Make sure dirt or debris does not enter the oil
tank.
4.
clockwise until it is hand tight.
5. Wipe away any spilled oil.
To allow venting of the oil reservoir, small breather
channels are provided between the oil tank cap and the
strainer. To prevent leakage, make sure the chain saw is
stored in a horizontal position with the oil tank cap facing
upward when it is not in use.
To prevent excessive wear, the chain and guide bar must
be evenly lubricated during operation.
Lubrication is automatic. Never work without chain
lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It is
therefore important to check both chain lubrication and the
oil level gauge (15) every use.
Never use the saw when the oil level is below the "Min."
mark on the oil level gauge. When the oil level is below
the "Min." mark, add oil until the oil level reaches the
"Max." mark.
