Figure 9. Pump Control Box Components

INITIAL SERVICING

The pump's engine (Figure 9) 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. Muffler – Used to reduce noise and emissions. NEVER touch the muffler while it is hot! Serious burns can result. NEVER operate the engine with the muffler removed.

2.Dip Stick – Remove dipstick to determine if the engine oil level is low. If low add oil as specified in Table 4, page 30.

3. Speed Control Lever – This lever is connected to the throttle control which is located on the side of the engine compartment cover. Use this lever to control engine speed.

4.Oil Filter – Prevents dirt and other debris from entering the engine. Service the oil filter as recommended in the maintenance section of this manual.

5.Side Oil Drain Plug – Remove this plug to drain engine oil from the engine crankcase. For best results drain engine oil when oil is warm.

6. Air Filter/Cover – Prevents dirt and other debris from entering the fuel system. Release the latches on the side of the air filter cover to gain access to filter element.

7. Starter/Solenoid – This engine uses a 12 VDC , 2.7kW (3.7 HP) starter motor with solenoid.

8.Front Oil Drain Plug – Remove this plug to drain engine oil from the engine crankcase. For best results drain engine oil when oil is warm.

9. V-Belt Cover – Remove this cover to gain access to the V- belt.When replacing V-belt , use only recommended type V-belt.

Operating the engine without an air

NOTE filter, with a damaged air filter, or a filter in need of replacement will allow dirt

to enter the engine, causing rapid engine wear.
