ENGINE COMPONENTS

Figure 6. Engine Controls and Components

INITIAL SERVICING

The engine (Figure 6) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufacturers engine manual for instructions & details of operation and servicing.

1. Fuel Filler Cap – Remove this cap to add unleaded gasoline to the fuel tank. Make sure cap is tightened securely. DO NOT over fill.

DANGER — Explosive Fuel Hazards

Fuel is extremely flammable and its vapors can cause an explosion if ignited.

DO NOT start the engine near spilled fuel or combustible fluids. In the event of a fuel spill, wait until the fuel residue has

been completely wiped up and the area surrounding the engine is dry before starting the engine.

DO NOT fill the fuel tank while the engine is running or hot. DO NOT overfill tank, since spilled fuel could ignite if it comes into contact with hot engine parts or sparks from the ignition system. Store fuel in approved containers, in well-ventilated areas and away from sparks and flames.

2. Throttle Lever – Used to adjust engine RPM speed (lever advanced forward SLOW, lever back toward operator FAST).

3. Engine ON/OFF Switch – ON position permits engine starting, OFF position stops engine operations.

4. Recoil Starter (pull rope) – Manual-starting method. Pull the starter grip until resistance is felt, then pull briskly and smoothly.

5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop the flow of fuel.

6. Choke Lever – Used in the starting of a cold engine, or in cold weather conditions. The choke enriches the fuel mixture.

7. Air Cleaner – Prevents dirt and other debris from entering the fuel system. Remove wing-nut on top of air filter cannister to gain access to filter element.

Operating the engine without an air filter, with a damaged air filter, or a filter in need of replacement will allow dirt to enter the engine, causing rapid engine wear.

WARNING — Burn Hazards

Engine components can generate extreme heat. To prevent burns, DO NOT touch these areas while the engine is running or immediately after operation. Never operate the engine with the muffler removed.

8. Spark Plug – Provides spark to the ignition system. Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean spark plug once a week.

9. Muffler – Used to reduce noise and emissions.

10. Fuel Tank – Holds unleaded gasoline. Fuel tank capacity is 1.7 gallons (6.5 liters) For additional information refer to engine owner's manual.
