maintaining the blower.
2. Always wear safety glasses and long pants when
operating or maintaining this machine. Do not wear
loose-fitting clothing.
3. Always disconnect the spark plug wire before
adjusting or maintaining this machine.

blower.
6. Altering this machine in any way may cause injury
to the operator or bystanders.
7. Keep people and pets away from the blower when
in use.
8. When operating, never direct the air stream at walls
or vertical objects which can deflect debris back at
you.
9. When operating, never direct the air stream at
painted objects.
10. If a breakdown occurs, shut off the engine
immediately, disconnect the spark plug wire and do
not connect until repairs have been made.
11. Never run the engine indoors without adequate
ventilation. Exhaust fumes are deadly.
12. To avoid serious burns, do not touch the engine,
exhaust pipe or muffler while the engine is running
or until it has cooled after it has been shut off.
13. Stop the engine and allow it to cool before refilling
the gas tank.
14. Gasoline is extremely dangerous and flammable.
Do not permit open flames or sparks near the
engine at any time.
15. Keep the blower and especially the engine air
screen and cooling fins clean and free of grease,
grass and leaves to reduce the chance of fire and
to permit proper cooling.
PREPARATION
1. Open the packing. Make certain the engine’s
spark plug wire is disconnected.
2. Assemble the upper and lower handles to the
engine plate as shown in figure 1.
3. Check and tighten all nuts and bolts as necessary.
4. Check the air pressure in the tires. It should be 18-
22 psi. CAUTION: Do not overinflate.
5. Fill the engine with oil. The oil should be up to but
not over the “Full” mark on the dipstick. Above 32°
F. use SAE 30 oil. Below 32° F. use SAE 5W20 or
SAE 5W30.
6. Fill the gas tank. Use fresh, clean, regular,
unleaded gasoline. Leave 1/4 inch at the top of the
tank for expansion.

OPERATING INSTRUCTIONS
Prior to Each Day’s Use:
1. Disconect the engine’s spark plug wire.
2. Clean the cooling air intake screen and cooling fins.
(See engine manual).
3. Clean the air filter paper element by gently tapping on
the flat side. Do not wash or use pressurized air. (See
engine manual).
4. Position the blower on a level surface and check the
engine oil level.
5. Fill the gas tank.
6. Check and tighten all nuts and bolts as necessary.
To Start the Blower:
1. Connect the engine’s spark plug wire.
2. Open the fuel shutoff valve.
3. Move the engine switch to “ON”. Move the choke control
on the engine to “CHOKE”. Move the throttle control to
halfway between “SLOW” and “FAST”.
4. Grasp the starter grip and pull slowly until the starter
engages and then pull the cord rapidly to overcome
compression, prevent kickback and start the engine.
Allow the cord to recoil slowly. Repeat if necessary.
5. Once the engine starts, close the choke control and
when the engine has warmed up, adjust the throttle to
produce the amount of sweeping power required.
6. Move to the point where you want to begin sweeping.
The sweeping action is most effective if, as you move
forward, you keep the front of the machine down and
close to the work surface to blow out holes and
crevices.
7. To shut off the machine, move the engine throttle
control to the “SLOW” position, shut off the engine
switch and after the engine has stopped, disconnect the
engine’s spark plug wire and shut the fuel shutoff valve.
8. After use, thoroughly clean the machine especially the
engine’s air intake screen and cooling fins.
NOZZLE OPERATING INSTRUCTIONS
The blower is equipped with a dual purpose nozzle (air
outlet):
1. When the nozzle is oriented in
this position (see Fig. 1 and
illustration 1) leaves and debris
on ground level are propelled to
a distance proportion to engine
speed. Leaves at the top of the
pile have a tendacy to circle
back from eddy currents that are
created by the blower air flow.
2. When the nozzle is oriented as
shown in Figure 2 and
illustration 2 - The air flow will
naturally “knock down” leaves
and prevent them from circling
back from eddy currents.
To change position of nozzle:
1. Unscrew and remove thumb
knob (060043) from u-bolt (706397).
2. Pull out u-bolt.
3. Pull off nozzle (706887), rotate 180° and replace back
onto unit.
4. Replace ubolt and thumb knob.
To change position of handle:
1. Remove hardware connecting upper handle (706907) to
lower handles (706908).
2. Relocate upper handle — either lower of higher to next
set of mounting holes.
3. Replace hardware and tighten.
