TOOLS FOR ASSEMBLY
You will need these tools to assemble your chain saw:
1. Ring wrench SW 11
2. Screwdriver / spark plug wrench
•
ASSEMBLY REQUIREMENTS
Your new chain saw will require adjustment of chain,
filling the fuel tank with correct fuel mixture and filling the
oil tank with lubricating oil before the unit is ready for
operation.
Read the entire user manual before attempting to
operate your unit. Pay particular attention to all safety
precautions.
This manual contains not only safety information but also
general information on how to assemble, operate and
service the saw.

GUIDE BAR / SAW CHAIN / CLUTCH COVER
INSTALLATION
TO INSTALL GUIDE BAR:
To ensure the bar and chain receive oil, ONLY USE THE
ORIGINAL STYLE BAR with the oil passage hole (A) as
illustrated above (Fig. 3A).
1. Make sure the Chain brake lever is pulled back into
the DISENGAGED position (Fig. 3B)
2. Remove the bar fastening nut (B). Remove the 2
screws of the chain brake cover (C). Remove the
chain brake cover
by pulling it straight out with a
strong tug (Fig. 3C).
Note:
The chain may sag a little. This is normal.
3. Using a screwdriver, run the adjustment screw (D)
COUNTERCLOCKWISE until the TANG (E) (project-
ing prong) is to the end of its travel toward the
clutch drum and sprocket (Fig. 3D).
4. Place the slotted end of the guide bar over the bar
bolts (F). Position the bar so that the adjustment
TANG fits into the lower hole (G) on the guide bar
(Fig. 3E).
TO INSTALL SAW CHAIN:
1. Spread chain out in a loop with cutting edges (A)
pointing CLOCKWISE around loop (Fig. 4A).
2. Slip the chain around the sprocket (B) behind the
clutch (C). Make sure the links fit between the
sprocket teeth (Fig. 4B).
3. Guide the drive links into the groove (D) and around
the end of the bar (Fig. 4B).
NOTE:
The saw chain may droop slightly on the lower
part of bar. This is normal.
4. Pull the chain bar forward until the chain is closely
seated. Make sure that all the drive links are in the
groove of the bar.
5.
Install the clutch cover and tighten the 2 screws.
Make sure the chain does not slip off of the bar.
Install the 2 nuts hand tight and follow tension
adjustment instructions in Section
SAW CHAIN
TENSION ADJUSTMENT.
NOTE:
The guide bar retaining nuts are installed only
hand tight at this point because saw chain adjustment is
required. Follow instructions in Section
SAW CHAIN
TENSION ADJUSTMENT.

SAW CHAIN TENSION ADJUSTMENT
Proper tension of saw chain is extremely 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.
TO ADJUST SAW CHAIN:
1.
Hold nose of guide bar up and turn adjustment screw
(D) CLOCKWISE to increase chain tension. Turning
screw COUNTERCLOCKWISE will decrease amount
of tension on chain. Ensure the chain fits snugly all
the way around the guide bar (Fig. 5).
2.
After making adjustment, and while still holding nose
of bar in the uppermost position, tighten the bar
retaining nuts securely. Chain has proper tension
when it has a snug fit all around and can be pulled
around by gloved hand.
NOTE:
If chain is difficult to rotate on guide bar or if it
binds, too much tension has been applied. This requires
minor adjustment as follows:
A. Loosen the bar retaining nut so they are finger tight.
Decrease tension by turning the bar adjustment
screw COUNTERCLOCKWISE slowly. Move chain
back and forth on bar. Continue to adjust until chain
rotates freely, but fits snugly. Increase tension by
turning bar adjustment screw CLOCKWISE.
B. When saw chain has proper tension, hold nose of
bar in the uppermost position and tighten the bar
retaining nut securely.
