5 - OPERATING INSTRUCTIONS
5-3. RE-STARTING A WARM ENGINE
1.
Make sure the on/off switch is in the “I” position.
2. Depress the primer bulb 10 times.
3. Set the throttle latch. Latch throttle advance: depress
latch and hold squeeze throttle trigger release trigger
and then the latch.
4. Pull the starter rope rapidly 4 times. The engine
should start.
5. Release the throttle latch. The throttle latch will be
released while you press the trigger.
6. If the engine still can not start, follow the step as “To
start engine” section in this user manual.
5-4. TO STOP ENGINE
1. Release trigger and allow engine to return to idle
speed.

AS FOLLO
WS:
1. Place saw on a clear, firm, flat surface.
2. Start engine.
3. Grasp the rear handle (A) with your right hand (Figure
5-5A).
4. With your left hand, hold the front handle (B) [not
CHAIN BRAKE
®
lever (C)] firmly (Figure 5-5A).
5. Squeeze the throttle trigger to 1/3 throttle, then imme-
diately activate the CHAIN BRAKE
®
lever (C) (Figure 5-
5A).
WARNING
Activate the CHAIN BRAKE
®
slowly and deliberately. Keep
the chain from touching anything; don’t let the saw tip for-
ward.
6. Chain should stop abruptly. When it does, immediately
release the throttle trigger.
WARNING
If chain does not stop, turn engine off and take your unit to
the nearest Authorized Service Center for service.
7. If CHAIN BRAKE
®
functions properly, turn the engine
off and return the CHAIN BRAKE
®
to the DISEN-
GAGED position.
5-6. SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the saw with
too little oil will decrease cutting efficiency
, shor
ten sa
w
chain life, cause rapid dulling of chain, and cause exces-
siv
e wear of bar from overheating. Too little oil is evidenced
b
y smok
e
, bar discolor
ation or pitch b
uild-up.
NOTE: Saw chain stretches during use, particularly when it
is new, and it will occasionally be necessary to adjust and
tighten it. New chain will require adjustment after about 5
minutes of operation.
5-7. AUTOMATIC OILER
Your chain saw is equipped with an automatic clutch driven
oiler system. The oiler automatically delivers the proper
amount of oil to the bar and chain. As the engine speed
increases, so does the oil flow to the bar pad. There is no
flow adjustment. The oil reservoir will run out at approxi-
mately the same time as the fuel supply runs out.

6 - GENERAL CUTTING INSTRUCTIONS
6-1. FELLING
Felling is the term for cutting down a tree. Small trees up to
6-7 inches (15-18cm) in diameter are usually cut in a single
cut. Larger trees require notch cuts. Notch cuts determine
the direction the tree will fall.
FELLING A TREE:
WARNING
A retreat path (A) should be planned and cleared as nec-
essary before cuts are started. The retreat path should
extend back and diagonally to the rear of the expected line
of fall, as illustrated in Figure 6-1A.
CAUTION
If felling a tree on sloping ground, the chain saw operator
should keep on the uphill side of the terrain, as the tree is
likely to roll or slide downhill after it is felled.
NOTE: Direction of fall (B) is controlled by the notching cut.
Before any cuts are made, consider the location of larger
branches and natural lean of the tree to determine the way
the tree will fall.
WARNING
Do not cut down a tree during high or changing winds or if
there is a danger to property. Consult a tree professional.
Do not cut down a tree if there is a danger of striking utility
wires; notify the utility company before making any cuts.
GENERAL GUIDELINES FOR FELLING
TREES:
Normally felling consists of 2 main cutting operations,
notching (C) and making the felling cut (D).
Start making the upper notch cut (C) on the side of the tree
facing the felling direction (E). Be sure you don t make the
low
er cut too deep into the trunk.
The notch (C) should be deep enough to create a hinge (F)
of sufficient width and strength. The notch should be wide
enough to direct the fall of the tree for as long as possible.
WARNING
Ne
ver walk in front of a tree that has been notched.
Mak
e the f
elling cut (D) from the other side of the tree and
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)
(Figure 6-1B).
Ne
v
er sa
w completely through the tr
unk.
Always leave a
hinge. The hinge guides the tree. If the trunk is completely
cut through, control over the felling direction is lost.
Inser
t a w
edge or f
elling le
ver in the cut well before the tree
becomes unstable and starts to move. This will prevent the
guide bar from binding in the felling cut if you have mis-
judged the f
alling direction.
Mak
e sure no b
ystanders have
entered the range of the falling tree before you push it over.
WARNING
Before making the final cut, always recheck the area for
bystanders, animals or obstacles.
FELLING CUT:
1.
Use wooden or plastic wedges (G) to prevent binding
the bar or chain (H) in the cut. Wedges also control
felling (Figure 6-1C).
2. When diameter of wood being cut is greater than the
bar length, make 2 cuts as shown (Figure 6-1D).
WARNING
As the felling cut gets close to the hinge, the tree should
begin to fall. When tree begins to fall, remove saw from cut,
stop engine, put chain saw down, and leave area along
retreat path (Figure 6-1A).
