Set-Up
Tire Pressure
Check the air pressure in both tires. The air pressure should be between 15-20 PSI.
Keep both tires equally inflated to help prevent machine from pulling to one side.
Checking and Adding Oil
The engine is shipped without oil in the engine. You must fill the engine
with oil before operating. Running the engine with insufficient oil can
cause serious engine damage and void the product warranty.
Initial Use
1. Remove the oil fill dipstick.
2. Place the tiller on level ground, use a funnel to empty entire contents of the
oil bottle provided with the unit into the engine.
3. Replace the oil fill dipstick and tighten.
Checking and adding oil
1. Place the tiller on a flat, level surface.
2. Remove the oil filler cap/dipstick and wipe the dipstick clean. See Figure 8.

3. Insert the cap/dipstick into the oil filler neck, but do not screw it in.
4. Remove the oil filler cap/dipstick. If the level is low, slowly add oil until oil
level registers between high (H) and low (L), Figure 8.
NOTE: Do not overfill. Overfilling with oil may cause smoking, hard starting,
or spark plug fouling.
5. Replace and tighten cap/dipstick firmly before starting engine.
NOTE: DO NOT allow oil level to fall below the "L" mark on the dipstick. Doing
so may result in equipment malfunctions or damage.
NOTE: To change the oil on your engine, see the Service and Maintenance
section of this manual.

ASSEMBLY

Fuel Recommendations

Use automotive gasoline (unleaded or low leaded to minimize combustion chamber
deposits) with a minimum of 87 octane. Gasoline with up to 10% ethanol or 15% MTBE
(Methyl Tertiary Butyl Ether) can be used. Never use an oil/gasoline mixture or dirty
gasoline. Avoid getting dirt, dust, or water in the fuel tank. DO NOT use E85 gasoline.
• Refuel in a well-ventilated area with the engine stopped. Do not smoke or
allow flames or sparks in the area where the engine is refueled or where
gasoline is stored.
• Do not overfill the fuel tank. After refueling, make sure the tank cap is closed
properly and securely.
• Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite.
If any fuel is spilled, make sure the area is dry before starting the engine.
• Avoid repeated or prolonged contact with skin or breathing of vapor.

Adding Fuel

Use extreme care when handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never fuel the machine indoors or
while the engine is hot or running. Extinguish cigarettes, cigars, pipes and
other sources of ignition.
1. Be sure engine is outdoors and in a well-ventilated area.
2. Clean area around the fuel fill cap and remove the fuel fill cap.
3. Using an approved red GASOLINE container, add fuel slowly, being careful to
avoid spilling.
4. Fill the tank until the fuel reaches the "fuel full" indicator mark. See Figure 9.
5. Replace the fuel cap and tighten securely. Wipe up spilled fuel before starting
engine. If fuel is spilled DO NOT start engine. Move machine away from area of
spillage. Avoid creating any source of ignition until fuel vapors are gone.
