PRE-OPERATION for Starting

(See Fig. 2)

1.ATTACH THE FLANGE AND CHECK VALVES (See Fig. 2-q)

Attach the suction flange, delivery flange and check valves to the pump when operating the brand new pump for the first time.

q Check valves	w Delivery
e Suction

CAUTION

Be careful not to overtighten the bolts. Suction flange tightening torque : 90-120 kg-cm Delivery flange tightening torque : 90-120 kg-cm

2.CONNECT SUCTION HOSE (See Fig. 2-w)

Use a reinforced-wall or wire braided hose to prevent suction collapse.

Since the pump self-priming time is directly proportional to hose length, a short hose is recommended.

CAUTION

Always use a strainer with the suction hose. Gravel or debris sucked into the pump will cause serious damage to the impeller and the pump casting.

■Select the viscosity based on the air temperature at the time of operation as shown in the table. (See Fig. 2-r)

5. CHECK FUEL (See Fig. 2-y)

WARNING

Do not refuel while smoking, near an open flame or other such potential fire hazards. Otherwise fire accident may occur.

■Stop the engine and open the cap.

■Use automotive unleaded gasoline only.

This engine is certified to operate on automotive unleaded gasoline.

Fuel Tank Capacity

Refer to “SPECIFICATIONS” Page 12 for fuel tank capacity

■Close the fuel cock before filling the fuel tank.

■Do not fill above the top of the fuel filter screen (marked w), or the fuel may overflow when it heats up later and expands.

3.CONNECT DELIVERY HOSE (See Fig. 2-e)

When using a fabric hose, always use a hose band to prevent the hose from disconnecting under high pressure.

4.CHECK ENGINE OIL (See Fig. 2-t)

Before checking or refilling engine oil, be sure the engine is located on stable, level surface and stopped.

■Do not screw the oil gauge into the oil filler neck to check oil level. If the oil level is low, refill to the upper level with the following recommended oil.

■Use 4-stroke automotive detergent oil of API service class SE or higher grade (SG, SH or SJ is recommended).

■When filling the fuel tank, always use the fuel filter screen.

■Wipe off any spilled fuel before starting the engine. (See Fig. 2-u)

6.CHECK PRIMING WATER (See Fig. 2-i)

It is recommended that the water chamber of pump casing should be primed with full of water before operating.

WARNING

Never attempt to operate the pump without priming water or the pump will overheat. Extended dry operation will destroy the mechanical seal.

If the unit has been operated dry, stop the engine immediately and allow the pump to cool before adding priming water.
