Make sure all threaded fuel connections are wrapped with

three to four turns of Teflon

approved for use with petroleum fuels.

Tighten the bung adapter snugly onto the tank. Place the

union ring gasket into the inlet fitting. Thread the suction

pipe into the inlet fitting and tighten snugly.

Clean the tank interior of all dirt and debris. Extend the suc-

tion pipe to its full length and insert it into the tank opening.

(Figure 1) The suction pipe will adjust to rest on the tank

bottom. Place the pump on the bung adapter and tighten

the union ring with a pipe wrench. Make sure the union ring

is not cross-threaded. Make sure the tank is vented. A vent

cap rated at 3 psi or less is recommended.

Install Electrical Connections

Connect 12-volt pumps to a 12-volt battery. Connect 24-

volt pumps to a 24-volt battery. Do not attempt connection

to a 115-volt or 230-volt power source.

To install the power cord, remove the electrical coverplate.

(Figure 2) Trim the power cord to the desired length. Strip

7.5 to 10 cm of outer insulation from the power cord. For the

M-240S, this is the end without the fuse. Then strip 1.3 cm

of insulation from the red and black wires. Slide the strain

relief grip onto the power cord so that the threaded end of

the strain relief grip faces the stripped power cord wires.

(Figure 3) Insert the power cord through the inlet on the back

of the pump. Using wire nuts, connect black wire to black

and red wire to red in the pump's electrical cavity. Position

the wires inside the electrical cavity and tighten the strain

relief grip securely. (Figure 4) Make sure mating surfaces are

clean, install electrical coverplate, and tighten screws se-

curely.

NOTE: By following the instructions above, the system is

wired for negative ground. If you require positive grounding

(24-volt systems), remove the fuse and fuse holder from

the power cord's red wire and splice it to the black wire.

Attach the black power cord wire to the negative (–) ter-

minal of the battery. Attach the red power cord wire to the

positive (+) terminal. Reverse connections for positive

grounded systems.

Install Hose and Nozzle

After sealing threads, tighten the hose into the pump outlet

and the nozzle on the hose. The nozzle can be placed in the

nozzle holder only when the pump is off. When in the nozzle

holder, the nozzle can be locked in place.

OPERATIONS

Always follow safety precautions when operating this equip-

ment. Review the Safety Instructions above. Before each

use, repair leaks around seals or connections. Make sure

hoses are in good condition and connections are tight. Make

sure the work area is dry. Make sure the pump is properly

grounded. Repair any corroded or damaged wiring before

use. Ensure the tank contains enough fuel. Make sure the

fuel is not contaminated with debris. Tighten loose tank lids

regularly.

To Dispense Fuel

Turn the pump on by removing the nozzle from the holder

and push the switch lever up. Insert the nozzle into the re-

ceiving tank and squeeze the handle to start fuel flow. After

dispensing fuel, release the nozzle handle, turn the pump

off, and return the nozzle to its holder.

This pump is designed to be self-priming. If fuel is not deliv-

ered within 15 to 20 seconds, turn the pump off. Refer to

priming information given above. An automatic bypass valve

prevents pressure build up when the pump is on with the

nozzle closed. To avoid pump damage, do not run the pump

more than 10 minutes with the nozzle closed. After running

the pump for a maximum of 30 minutes, allow it to cool for

30 minutes.

Motor Protector

(Models M-150S and M-180S only)

The motor protector trips automatically. This feature pro-

vides added protection against motor damage and must be

reset manually.

When the motor protector trips, reset by turning the switch

to OFF. Let the pump cool then turn ON again. If the motor

protector trips again, see the Troubleshooting Section of this

manual.

Motor Protector

(M-240S model)

An inline fuse provides Overload Protection on the 24-volt

models. Follow the instructions in the Repair Section to re-

place the fuse.

MAINTENANCE

Clean the inlet strainer after every 40 hours of operation or if

low flow occurs.

To Clean or Replace Strainer

Turn the pump off and disconnect from power. Remove the

strainer coverplate. (Figure 5) Remove the inlet strainer and

inspect for damage or clogs. Clean the strainer with a soft-

bristled brush and solvent. If the strainer is very dirty, com-

pressed air may be used. If damaged, replace the strainer.

NOTE: A very dirty strainer can indicate a contaminated

fuel tank. Clean the tank as necessary.

Clean the coverplate and O-ring. Coat the O-ring lightly with

grease. Place the strainer in the cavity. Ensure the coverplate

O-ring is properly seated and tighten the strainer coverplate.

TROUBLESHOOTING

A. MOTOR DOES NOT RUN

1. Fuse blown. Inspect fuse in fuse holder on power

cord for Model M-240S. If blown, replace fuse.

2. Switch defective. Remove switch coverplate and in-

spect switch. Replace if necessary.

3. Motor burned out. Inspect and replace as neces-

sary.
