The throttle lever controls the choke, engine
speed and stops engine.
(1) Choke
(Gradually move lever to
Slow position once engine
starts.)
To increase or decrease
engine speed:
(2) Fast
(3) Part-Throttle
(4) Slow
To stop engine:
(5) Stop (Stop Engine)
FILLING FUEL TANK
To add fuel to fuel tank:
1. Put unit in open or well-ventilated area.
2. Stop engine and allow to cool.
3. Clean fuel cap and surrounding area.
4. Remove cap.
IMPORTANT: See engine manual for proper
fuel type and grade.
5. Fill fuel tank to below bottom of filler
neck to allow for fuel expansion. See
SPECIFICATIONS on page 29.
IMPORTANT: DO NOT OVERFILL! This
equipment and/or its engine may include
evaporative emissions control system
components, required to meet EPA and/or
CARB regulations, that will only function
properly when the fuel tank has been filled to
the recommended level. Overfilling may
cause permanent damage to evaporative
emissions control system components. Filling
to the recommended level ensures a vapor
gap required to allow for fuel expansion. Pay
close attention while filling the fuel tank to
ensure that the recommended fuel level
inside the tank is not exceeded. Use a
portable gasoline container with an
appropriately sized dispensing spout when
filling the tank. Do not use a funnel or other
device that obstructs the view of the tank
filling process.
6. Replace fuel cap and tighten.
7. ALWAYS clean any spilled fuel.
GASOLINE
IMPORTANT: ALWAYS use gasoline that
meets the following guidelines:
• Clean, fresh gasoline.
• A minimum of 87 octane/87 AKI (91
RON). High altitude use may require a
different octane. Consult your engine
manual.
• Gasoline with up to 10% ethanol
(gasohol) or up to 10% MTBE (methyl
tertiary butyl ether) is acceptable.
• Use of any gasoline other than those
approved above will void the engine
warranty. If the pumps are not marked
for the content of alcohol or ethers,
check ethanol and MTBE levels with
the fuel supplier.
• Do not modify the fuel system to use
different fuels.
• Never mix oil and gasoline.
NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
Fuel Stabilizer
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
STARTING AND SHUT OFF
See Figure 10 for all Controls and Features.
NOTE: Start engine on a level surface that is
free of debris. It is recommended that the
engine is started over a non-grassy area, or
over grass that has been cut short.

dealer for repair.
WHEEL DRIVE ADJUSTMENTS
The unit should stop immediately when the
wheel drive control lever (Figure 10, item 4) is
released. The unit should not creep forward
when the wheel drive control lever is released
and the engine running.
If the unit creeps, the gap between the drive
rollers and tires must be adjusted. If the unit
does not accelerate smoothly or slips under
load, increase the traction and speed. See
Wheel Drive Traction Adjustment on page 19.
Drive Belt Guards
The lower guard covers the blade spindle and
drive belt. The upper guard covers the wheel
drive components.
To remove a guard:
1. Shut off unit.
2. Disconnect spark plug wire from spark
plug.
3. Unscrew two hex bolts from mounting
brackets and remove guard.
NOTE: Each mounting bolt includes a captive
flat washer and nyloc nut. The captive nut
prevents the bolt from separating from the

Wheel Drive Speed Adjustment
See Figures 14 and 15.
Wheel drive speed is determined by how
deep the wheel drive lower belt rides in the
variable speed (VS) pulley. The higher the
belt rides in the VS pulley groove, the slower
the wheel drive speed. The lower the belt
rides in the VS pulley groove, the faster the
wheel drive speed. To adjust wheel drive
speed:
1. Remove upper and lower drive belt
guards. See Drive Belt Guards on
page 18.
2. Release the tension from the wheel
drive lower belt. See Adjust Wheel Drive
Lower Belt Tension on page 20.
3. Loosen set screw in VS pulley.
4. To decrease wheel drive speed:
• Rotate the pulley outer half clockwise,
moving it inward. This causes the belt
to ride higher in pulley.
To increase wheel drive speed:
• Rotate the pulley outer half
counterclockwise, moving it outward.
This causes the belt to ride lower in
pulley.
5. Tighten the VS pulley set screw. Ensure
that set screw fully engages one of the
flats of the shaft.
6. Increase wheel drive lower belt tension.
See Adjust Wheel Drive Lower Belt
Tension on page 20.
7. Install drive belt guards.
Wheel Drive Traction Adjustment
The gap between the drive rollers and tires,
when wheel drive is disengaged determines
the amount of contact force when wheel drive
is engaged. Drive roller to wheel gap should
be 1/8 – 1/4" (3 – 6 mm).
NOTE: A smaller gap between rollers and
tires when wheel drive is disengaged
provides for more engaged traction, which is
helpful on sloped terrain.
1. Remove upper and lower drive belt
guards. See Drive Belt Guards on
page 18.
2. Loosen fine-adjustment knob to top end
of adjustment link. Do not remove.
3. Remove hairpin, washer and engage
plate from bell crank post.
4. Push the wheel drive frame back until
drive roller gap at wheels is 1/8 – 1/4" (3
– 6 mm). See Figure 17.
NOTE: Holes in the engage plate allow
traction adjustments to match rear wheel
height.
5. Install nearest hole of engage plate onto
bell crank post. See Figure 16.
6. Install hairpin and washer on bell crank
post.
