CAUTION – Read Manual

DO NOT attempt to operate the pump until the
Safety, General Information and Inspectionsections of this manual have been read and thoroughly understood. This section is intended to assist the operator with the initial
start-up of the diaphragm pump. It is extremely important that this section be read carefully before attempting to use the pump in the field.

Starting the Engine (HONDA engine)

Place the engine fuel valve lever (Figure 8) to the “ON” position.

Figure 8. Engine Fuel Valve Lever (ON Position)

Move the throttle lever (Figure 9) away from the slow position, about 1/3 of the way toward the fast position.

Place the choke lever (Figure 10) in the “OPEN ” position if a cold engine.

Figure 10. Engine Choke Lever (Open)

Place the choke lever (Figure 9) in the “CLOSED ” position if starting a warm engine or the temperature is warm.

Place the engine ON/OFF switch (Figure 12) in the “ON ” position.

Grasp the starter grip (Figure 13) and slowly pull it out. The resistance becomes the hardest at a certain position, corresponding to the compression point. Pull the starter grip briskly and smoothly for starting.
If the engine has started, slowly return the choke lever (Figure 14 ) to the “CLOSED” position. If the engine has not started repeat steps 1 through 6.

Before the pump is placed into operation, run the engine for several minutes. Check for fuel leaks, and noises that would associate with a lose component.
To begin pumping, place the throttle lever (Figure 15) in the “RUN” position.

Pump speed can be regulated with the engine throttle control from full volume, 65 strokes per minute, to about 40 strokes per minute for lesser volume. Smoothest operation can be determined by trying to pump at several speeds. Limit maximum speed to 65 strokes per minute of the diaphragm (2,800 RPM engine speed).

Stopping The Engine Normal Shutdown

Move the throttle lever to the IDLE position (Figure 16) and run the engine for three minutes at low speed.
After the engine cools, turn the engine ON/OFF switch to the “OFF” position (Figure 17).
Place the fuel shut-off lever (Figure 18) in the ”OFF” position.
