Saw Chain
• Do not change accessories, inspect, adjust or
clean tool when it is connected to a power
source. Accidental start-up can result in
serious injury.
• Always disconnect tool from power source
before attempting to adjust or service the chain
saw. Accidental start-up can result in serious
injury.
• Always wear protective gloves when handling
or adjusting the saw chain. The saw chain can
cut even when stationary.
Failure to observe these warnings could result in
severe injury or death.
Saw Chain Tension
Check the saw chain tension frequently during use and
adjust as often as necessary to keep the chain snug,
but not too tight. The saw chain is properly tensioned
when you can pull the chain around the guide bar easily
and have a 1/8 inch clearance on the bottom of the
guide bar. The saw chain and guide bar should always
be cool when checking and/or adjusting tension.
Checking Tension (See Figure 9)
1. STOP THE POWER SOURCE. DISCONNECT THE
TOOL FROM THE POWER SOURCE.
2. Pull the saw chain around the guide bar. The chain
should pull easily. If it cannot be pulled, it may be
adjusted too tight, bar groove may be damaged,
chain drive links may be damaged, or hydraulic
pressure may be trapped in the saw motor. If there
is pressure in the motor, the hoses were discon-
nected improperly and the pressure must be
released. See Hose Connection, Disconnecting
Hoses for proper procedure.
3. Pull the saw chain on the bottom of the guide bar
(approximately 2 lb. load). There should be 1/8 inch
(3.2 mm) chain clearance at the center of the bar. If
not, chain tension adjustment is necessary
Saw Chain – Adjusting Tension (See Figures 1 and 2)
1. Loosen the two guide bar mounting screws (6).
2. Turn the saw chain tension adjusting screw (5) until
the proper chain tension is achieved.
3. Hold the guide bar nose (3) up and tighten the two
guide bar mounting screws (6). Torque to 150 inch-
pounds.

1. Run the saw at a low chain speed without cutting
any wood for 2 - 3 minutes. Make sure the automatic
oiler is working properly.
2. STOP THE POWER SOURCE. DISCONNECT
TOOL FROM THE POWER SOURCE. Allow the
chain and bar to cool. Check the chain tension and
adjust if necessary.
3. Reconnect tool to the power source. Start the power
source flow. Make a few easy cuts.
4. STOP THE POWER SOURCE. DISCONNECT THE
TOOL FROM THE POWER SOURCE. Allow the
chain and bar to cool. Recheck the chain tension
and adjust if necessary.
5. DO NOT BREAK-IN A NEW SAW CHAIN UNDER
