EC-42S CONCRETE MIXER — BASIC ENGINE COMPONENTS
Figure 3. Engine Controls and Components
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.
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.
WARNING
Adding fuel to the tank should be accomplished only when the engine is stopped and has had an opportunity to cool down. In the event of a fuel spill,
DO NOT attempt to start the engine until the fuel residue has been completely wiped up, and the area surrounding the engine is dry.
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) – |
| the starter grip until resistance is felt, then pull briskly and |
| smoothly. |
7. Air Cleaner – Prevents dirt and other debris from entering the fuel system. Remove
NOTE
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.
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.
WARNING
Engine components can generate extreme heat. To prevent burns, DO NOT touch these areas while the engine is running or immediately after operating. NEVER
operate the engine with the muffler removed.
10. Fuel Tank – Holds unleaded gasoline. For additional information refer to engine owner's manual.
