Using Proper Fuel

Use regular grade unleaded fuel with an octane rating of 87 octane or higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE reformulated fuel are acceptable. Do not use fuel or additives containing methanol as engine damage can occur.

Always use fresh, clean fuel that is purchased in a quantity that can be used within approximately 30 days, or add fuel stabilizer.

Fuel is blended to give best seasonal performance. To avoid engine performance problems such as hard starting or vapor lock, use in-season fuel. Use fuel during warm weather that was purchased during that season, and use fuel during cold weather that was purchased during that season.

Fuel can become stale in machines with engines that are used seasonally or infrequently during a season. Stale fuel can produce varnish and plug carburetor components which can affect engine performance.

Keep fuel storage container tightly covered and in a cool area out of direct sunlight. Fuel can break down and degrade if not sealed properly or exposed to sun and heat.

Condensation may collect in the fuel tank because of a variety of operating or environmental conditions and, over time, may affect your machine’s operation. Fill fuel tank at the end of daily use and store fuel in plastic containers to reduce condensation.

For best year-round performance and fuel-handling, add stabilizer to fuel immediately after fuel purchase. Such practice helps prevent engine performance problems and allows fuel storage in the machine all year without draining.

Filling Fuel Tank

c CAUTION: Avoid injury! Fuel vapors are explosive and flammable:

• Shut engine off before filling fuel tank.

• Do not smoke while handling fuel.

• Keep fuel away from flames or sparks.

• Fill fuel tank outdoors or in well ventilated area.

• Clean up spilled fuel immediately.

• Use clean approved non-metal container to prevent static electric discharge.

• Use clean approved plastic funnel without screen or filter to prevent static electric discharge.

IMPORTANT: Avoid damage! Dirt and water in fuel can cause engine damage:

• Clean dirt and debris from the fuel tank opening.

• Use clean, fresh, stabilized fuel.

• Fill the fuel tank at the end of each day’s operation to keep condensation out of the fuel tank.

• Use a non-metallic funnel with a plastic mesh strainer when filling the fuel tank or container.


Fill fuel tank at the end of each day’s operation to prevent condensation and freezing during cold weather.

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Allow engine to cool.

3. Remove any trash from area around fuel tank cap.

4. Remove fuel tank cap slowly to allow any pressure built up in tank to escape.

5. Fill fuel tank only to bottom of filler neck.

6. Install fuel tank cap.

Checking Tire Pressure


MIF

c CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly:

• Do not attempt to mount a tire without the proper equipment and experience to perform the job.

• Do not inflate the tires above the recommended pressure.

• Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel.

• Do not stand in front or over the tire assembly when inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add air, if necessary:

Tire Size

Pressure

Front 9x3.5-4

124 kPa (18 psi)

Rear 18x8.5-8

103 kPa (15 psi)


Adjusting Speed Control Lever Tension

c CAUTION: Avoid injury! Speed control lever tension must remain firm. A loose tension adjustment could cause unwanted forward travel and unpredictable speed.

Speed control spring tension is preset at the factory. It is set for normal walk behind operation. Under heavy load conditions, the unit may slow down at the higher speed. This can be corrected by increasing the spring tension.

1. Turn machine off.

2. Move speed control lever to full speed.

3. Release thumb locks and allow steering control levers to rotate down.


MX32174

4. Loosen nut (A) at spring tension bolt for each control arm and slide bolts down to rear of slots (B) to increase spring tension.

5. Test machine for proper performance. If performance is still not acceptable, a second adjustment is located at the pump.


MX32175

a. Loosen nut (C), each side, to slide spring anchor bolt locations. Increasing spring length will increase responsiveness and increase handle effort. Decreasing spring length will lower handle effort and reduce responsiveness.

Adjusting Handle Height Position

Three sets of mounting holes at each side of the handle assembly provide for height adjustment to enhance operator comfort.


MX32178

Picture Note: Left side shown.

1. Remove the cotter pins (A) securing the lower control linkage (B) and allow the control linkage to hang free.

2. Remove the two bolts (C) at each side that secure the handle assembly (D) to the frame. The rear bolt on the left side also secures the park brake switch (E).

3. Raise or lower the handle assembly as desired to align a different set of mounting holes in the handle with the mounting holes in the frame, then secure with original hardware. Both sides must be secured at the same height.

4. Lengthen control linkage to fit and install in control levers.

IMPORTANT: Avoid damage! Perform neutral switch position adjustment after adjusting handle height position.


5. Adjust neutral switch position and park brake switch.

Cleaning Plastic Surfaces

IMPORTANT: Avoid damage! Improper care of machine plastic surfaces can damage that surface:

• Do not wipe plastic surfaces when they are dry. Dry wiping will result in minor surface scratches.

• Use a soft, clean cloth (bath towel, diaper, automotive mitt).

• Do not use abrasive materials, such as polishing compounds, on plastic surfaces.

• Do not spray insect repellent near machine.


1. Wash surface with clean water and a mild liquid automotive washing soap.

2. Dry thoroughly to avoid water spots.

Cleaning and Repairing Metal Surfaces

Cleaning:

Follow automotive practices to care for your vehicle painted metal surfaces. Use a high-quality automotive wax regularly to maintain the factory look of your vehicle’s painted surfaces.

Repairing Minor Scratches (surface scratch):

1. Clean area to be repaired thoroughly.

IMPORTANT: Avoid damage! Do not use rubbing compound on painted surfaces.


2. Use automotive polishing compound to remove surface scratches.

3. Apply wax to entire surface.

Repairing Deep Scratches (bare metal or primer showing):

1. Clean area to be repaired with rubbing alcohol or mineral spirits.

2. Use paint stick with factory-matched colors available from your authorized dealer to fill scratches. Follow directions included on paint stick for use and for drying.

3. Smooth out surface using an automotive polishing compound. Do not use power buffer.

4. Apply wax to surface.
