AUTION:
For proper
engine
operation
and maximum
reliability,
pay strict
attention
to the oil and fuel
mixing instructions
on the 2-cycle
oil container.
Using improperly
mixed fuel can severely damage
the engine.
_
ARNING:
Gasoline
is extremely
flammable.
Ignited
vapors
may explode.
Always
stop
the engine
and allow
it to cool before filling
the fuel tank. Do not smoke
while
filling
the tank. Keep sparks
and open
flames
at a distance
from the area.
_[_
ARNING:
Remove
the fuel cap slowly
to avoid injury from fuel spray.
Never operate
the unit without
the fuel cap securely
in place.
_[_
AF{NING,
Add
fuel in a clean, well-ventilated
outdoor
area. Wipe
up any spilled
fuel immediately.
Avoid
creating
a source
of ignition
for spilt
fuel. Do not start
the engine
until fuel vapors
dissipate.

FUEL
MmXmNG
INSTRUCTmONS
Old fuel and improperly
mixed fuel are the two
main reasons
why the unit
may not run properly.
Be sure to use fresh, clean unleaded
gasoline
and
quality
synthetic
2-cycle
air-cooled
engine
oil. Do not use
automotive
oil or
boat oil; these oils will damage
the engine.
Obtaining
the
Correct
Fuel/Oil
Mixture
Thoroughly
mix the proper amount
of 2-cycle
engine oil with
unleaded
gasoline
in a separate
fuel container
(do not mix them
directly
in the
engine fuel tank). Use a 40:1 fuel/oil
ratio. See the table
for specific
gas
and oil mixing
ratios.
NOTE:
One
gallon
(3.8 liters) of unleaded
gasoline
mixed with
one 3.2 oz.
(95 ml) bottle
of 2-cycle
oil makes
a 40:1 fuel/oil
ratio.

When mixing fuel, follow
the instructions

on the oil containen
Always
read and follow
the safety rules relating to
fuel before fueling the unit.
NOTE:
Dispose
of any old fuel/oil
mix in accordance
with federal,
state and local regulations.
Using
Blended
Fuels
_
ARNING:
DO NOT USE E85 FUEL
mNTHIS
UNIT.
It has been proven
that fuel containing
greater
than 10%
ethanol will
likely damage
this
engine and void
the warranty.
Today's fuels are often
a blend of gasoline
and oxygenates
such as ethanol,
methanol
or MTBE
(ether). These alcohol-
blended
fuels absorb
water. As little
as 1% water
in the fuel can make
fuel and oil separate,
which
leads to the
formation
of acids during storage.
If you choose
to use a blended
fuel, or its use is unavoidable,
follow
these precautions:
*
Always
use fresh fuel (less than 30 days old)
*
Mix the fresh
unleaded
fuel with
2-cycle
engine
oil, as directed
above
*
Use the fuel additive
STA-BILĀ®
or an equivalent
*
Always
agitate the fuel mix before fueling the unit
*
Drain the fuel tank and run the engine
dry before
storing
the unit
Using
Fuel
Additives
The bottle
of 2-cycle
oil that came
with
this unit contains
a fuel additive
that will help inhibit corrosion
and minimize
the
formation
of gum deposits.
Using the 2-cycle
oil included
with this unit is recommended.
If unavailable,
use a good
2-cycle
oil designed
for air-cooled
engines
along with a fuel additive,
such as STA-BIL _ Gas
Stabilizer
or an equivalent.
Add 0.8 oz. (23 ml) of fuel additive
per gallon of fuel according
to the instructions
on the
container.
NEVER add fuel additives
directly
to the unit's fuel tank.
NOTE:
Never use engine or carburetor
cleaner products
in the fuel tank or permanent
damage
can occur.
_
ARNING:
Only
operate
this
unit in a well-ventilated
outdoor
area. Carbon
monoxide
exhaust
fumes |
can be lethal
in a confined
area.
J
I _
I WARN|NG."
Never operate
the unit without
the guide bar and saw chain
properly
installed,
i
BEFORE
STARTING
THE
ENGINE
*
Make sure the chain tension
is at the desired setting.
RefertoAdjusting
the Chain Tension
in the
Maintenance
and
Repair
section.
Make sure the bar-retaining
nuts are tight
to the guide bar cover.
Make sure the fuel tank
is filled
with fresh fuel.
Refer to
Oil and Fuel Information.
If the oil and fuel instructions
are
not understood,
do not attempt
to fuel the unit!
Make sure the bar lube reservoir
is filled with
bar and chain oil. Refer to
Adding
Bar and Chain Lubricant
in the
Assembly
Instructions
section.
Make sure the chain brake is disengaged
by pulling
the front hand guard
/
chain brake
back toward
the front handle
as far as possible.
Refer to
Testing the Chain Brake
in the
Assembly
Instructions
section.
Make sure the immediate
area is clear of any objects
or obstructions
that could
come
in contact
with the guide bar
and chain.
STARTmNG THE ENGINE
To help prevent accidental
start-ups,
this unit has a stop switch,
safety
latch and a throttle
control
trigger
that must be used together
to start
the unit.
1.
Move
the stop switch
down to the RUN position
(Fig. 7).
2.
Fully press
and release the primer
bulb 10 times, slowly
(Fig. 7).
Some amount
of fuel should
be visible
in the primer
bulb. If fuel
cannot
be seen in the bulb, press
and release the bulb until fuel is
visible.
3.
Move
the choke lever to Position
1 (Fig. 8). This will lock the
throttle
into the wide
open
position.
4.
Do
not touch
the
throttle
control
trigger.
Place the unit on a
firm,
flat surface.
Crouch
in the starting
position
and hold the unit
firmly, as shown
(Fig. 9). Grip the front handle with
the left hand
and put the right
foot in the boot loop.
5.
Do
not touch
the
throttle
controm trigger.
Pull the starter
rope 5
times
in a controlled
and steady
motion.
NOTE:
This unit uses the AST starting
system,
which
significantly
reduces the effort required
to start
the engine.
You must pull
the starter
rope out far enough
to hear the engine attempt
to
start.
There is no need to pull the rope briskly - there is no
harsh resistance
when
pulling.
Do not pull the rope to its
limit, as this may cause the rope to break. Do not let the
rope snap back.
Hold the handle and let the rope rewind
slowly.
Be aware that this starting
method
is vastly
different
from (and much easier than) what you may be used to.
6.
Do
not touch
the
throttme controm trigger.
Move the choke
lever
to Position
2 (Fig. 8).
7.
Do
not touch
the
throttle
control
trigger.
Pull the starter
rope 3-
5 times in a controlled
and steady motion to start the engine.
8.
Do
not touch
the
throttle
control
trigger.
Allow
the engine
to
warm
up for 30-60
seconds.
9.
Depress
and release the throttle
control trigger
to idle the engine.
The unit is now ready for use.
IF...
The engine does not start, go back to step 2.
IF...
The engine fails to start
after a few attempts,
move the
choke
lever to Position
2 and squeeze the throttle
control
trigger.
Pull the starter
rope 3-8
times in a controlled
and
steady
motion. The engine should
start.
If not, repeat.
IF...
The unit idles roughly,
use a Phillips
or standard
screwdriver
to turn the idle adjustment
screw
(Fig. 10) 1/4 to 1/2 turn
clockwise
or until the unit idles smoothly.
IF...
The saw chain turns
while the unit is idling, use a Phillips or
standard
screwdriver
to turn the idle adjustment
screw
(Fig.
10) counterclockwise
until the saw chain
stops
and the unit
continues
to idle.
IF...
The engine starts
and idles smoothly,
begin the chain
brake
test.
Refer to
Testing the Chain Brake
in the
Assembly
Instructions
section.
IF WARM...If
the engine
is already warm,
perform
steps
6 - 9 to start
the unit.
STOPPING
THE ENGINE
1.
Release the throttle
control
trigger
and allow the engine to return
to idle speed.
2.
Move
the stop switch
up to the STOP position
(Fig. 7).

is in the STOP position.
For emergency
stopping,
push the chain
brake lever
/
hand guard forward
to engage the chain brake and then
move the stop switch
