Store tool and fuel in an area where fuel

from water heaters, electric motors or switches, furnaces, etc.
2. FUEL MIXTURE
e Your toot is powered by a two-cycle engine
which requires a fuel mixture of regular
unleaded gasoline and a high quality engine oil
specially made for 2-cycte, air cooled engines.
The internal design of the 2-cycle engine requires
lubricationof moving parts. Lubricationis provided
whenthe recommended mixture of gasolineand oil
is used.
• Gasoline must be clean and fresh. After a short
periodoftime, gasoline willchemically break down
and form compounds that cause hard startingand
damage in 2-cycleengines.
4. DO NOT USE:
• BIA OIL (Boating Institute of America) --- Does not have proper additives for air-cooled,
2-cycleengines and can cause enginedamage.
• AUTOMOTIVE OILDoes not have proper additives for 2-cycle
engines and can cause damage.
5. HOW TO MIX FUEL AND FILL TANK
a. Pour l/2ofthe regular unleadedgasolineto be used
into an approved, marked container. Do not mix
gasoline and oil directly in the fuel tank.
b. Add entire measure of engine oil.
c. Cover container tightly and shake for one minute.
• The correct measure of gasoline to oil is very
important. Too much oil in the mixture willfoul the
spark plug.
d. Slowly remove fuel container cover.
e. Add remainder of gasoline.
f. Cover container tightly and shake again.
ICAUTION:I TOOlittle oil will cause the engine to
overheat and seize,
h. Slowlyremove thefuel cap.Refer to"Specifications"
for fuel cap location.
• Always mix the fuel thoroughly in a container
sincegasolineand oildo not readilycombine.Donot
mix gasoline and oildirectly in the fuel tank.
i. Fill the tank using a spoutor funnel.
j. Reinstallthe fuel cap securely.

ADJUSTMENTS
Poor engine performance can be a result of other
causes such as dirty air filter, carbon build-up on
muffler outlets, etc. See "Trouble Shooting Chart"
before proceeding with carburetor adjustments.
• The'carburetor has been carefully adjusted at the
factow. Due to changes in altitude and operating
conditions,your carburetor may require adjusting.To
make the adjustment follow the procedure below
very carefully,
1. PREPARATION
a.) Use fresh fuel mix. See "Fueling Your Engine:'
b.) Remove air filter. See Figure 8.
c,) Turn Mixture Screw (Figure 6) clockwise
until fully closed, but do not overtighten. Figure

2. IDLE SPEED ADJUSTMENT
a.) Start the engine and turn throttle control to
halfway between "Fast" and "Slow".
b.) Operate the unitfor 3 minutesto warm up engine.
c.) Turn throttle control counterclockwise
41--,,, to slow setting.
d.) Adjust the Idle Speed Screw until the engine
idles as slow as possible without the engine
stalling.
Turn screw clockwise _
if the engine
stalls.
-- Turn screw counterclockwise _

I CAUTION: t The mixture setting is a highly
critical adjustment. If set incorrectly, permanent damage will occur to the engine. Do not
operate engine at fast throttle for prolonged
periods while making the mixture adjustment. The mixture screw should be in the
range of 3/4 to 1-1/4 turns open.
3. MIXTURE ADJUSTMENT:
a.) Adjust throttle knob to "Fast" position.
b.) Turn the Mixture Screw slowly clockwise
until the engine speed is reduced.
Note position.
c.) Turn the screw slowly counterclockwise
. Stop when the engine just begins
to run roughly,
d.) Turn the screw slowly the minimum amount

USING YOUR TOOL AS A BLOWER
A. OPERATING
INSTRUCTIONS
1. Read your Operator's Manual. Make certain you
completely understand and can follow
all warningsand
safety instructions, before operating the tool.
2 Always wear eye protection to prevent rocks or
debris from being blown or ricocheting into eyes
and face which can result in blindness and/or other
serious injury.
3. Always weara respirator or facemask when working in dusty environments.
4 Dress safely in long pants. Do not wear loose
clothing, jewelry, short pants or sandals; or go barefoot.
5. Check the tool before operation. Look for worn,
loose, missing or damaged parts. Do not use until the
tool is in proper working order.
6. Inspect the area before starting tool. Remove alt
debris and hard objects such as rocks, glass, wire, etc.
that can ricochet, be blown or otherwise cause dam age
during operation.
_,WARNING
Hold the tool for starting as shown in Figure 2. Do not
set the tool on any surface except a clean, hard area to
start the engine or while the engine is running. Debris
such as gravel, sand, dust, grass, etc. could be picked
up by the air intake and thrown out through the
discharge opening, damaging the tool or property or
causing serious injury to bystanders or the operator.
7. Keep children, bystanders, and animals safely
away. Before starting the engine and during operation,
make certain people and animals are away from the
work area - a minimum of 30 feet.
.
Check air intake opening and blower tubes frequently, always with the engine stopped and
spark plug disconnected. Keep vents and discharge tubes free of debris which can accumulate
and restrict proper air flow.
B. OPERATING
TIPS
1 Always work going away from solid objects such as
walls, large stones, automobiles and fences.
2 Clean spaces with corners by starting in corners
and moving outward to straight areas to prevent an
accumulation of debris which could fly into face
3. Be careful when working near plants. The force of
the air could damage tender plants.
4. Direct air flow by adjusting the nozzle position
down or to the side.
5. Vary or reduce the air flow by setting the throttle
knob at any position from "Fast" to "Slow:'
6. Use the assist handle located on the bottom of the
unit below the control panel when working above
the waist or when a two-handed grip is desired.
Refer to "Specifications" drawing, and Figure 7.
Use the correct operating position ( Figure 7). Do
not overreach or use from unstable surfaces such as
ladders, trees, steep slopes, roof tops, etc. Keep firm
footing and balance at all times.
10. Never place objects inside the blower tubes; always
direct the blowing debris away from people,
animals, glass, and solid objects such as trees,
automobiles,walls,etc.The force ofair can cause rocks,
dirt, or sticks to be thrownor to ricochet which may hurt
people or animals, break glass, or cause other damage.

A. AIR FILTER
A dirty air filter decreases engine performance and
increases fuel consumption.
Clean the Air Filter:
• Frequently,
• Always clean after 5 tanks of fuel or 5 hours of
operation, whichever is less.
Follow these steps:
1. Remove the air filter (located above the control
panel; see Figure 8 ).
2. Wash in soap and water.
I CAUTION:I Do not clean filter in gasoline or
other flammable solvent to avoid creating a fire
hazard.
3. Squeeze filterdr,/.
4. Add a small amount of oilto coat the filter.
NOTE: Avoid soaking the filterwith oil.
5. Squeeze out excess oil.
6. Replace the air filter.
! CAUTION: JThe air filter must be fitted into the
corners of the housing and under the center tab to
avoid engine damage.
Figure 8
B. FUEL
TANK
Never use gasoline that is more than 2 months old
in a fuel mixture. Gasoline begins to break down after
a short, period of time and will form compounds that
cause hard starting and damage in 2-cycle engines.
FAN HOUSING
1. Inspect the unit for fuel leaks each time it is used.
Repair or replace parts as necessary.
2, Using a fuel mix or gasoline over2 months old will
cause the engine to be difficult or impossible to
start.
