Product Manual
Motor Protector (Model M-240S)
An inline fuse provides motor protection on the 24-volt mod-
els. Follow the instructions in the Repair Section to replace
the fuse.
This pump is designed for minimum maintenance. Motor bear-
ings are sealed and require no lubrication. Inspect the pump
and components regularly for fuel leaks and make sure the
hose and power cord are in good condition. Keep the pump
exterior clean to help identify leaks.
Do not use this pump for water, chemicals, or herbicides.
Dispensing any fluid other than those listed in this manual will
damage the pump. Use of the pump with unauthorized fluids
will void the warranty.
To Clean or Replace Strainer
Turn the pump off and disconnect from power. Remove the
strainer coverplate. (Figure 5) Remove the inlet strainer and in-
spect for damage or clogs. Clean the strainer with a soft-bristled
brush and solvent. If the strainer is very dirty, compressed air
may be used. If damaged, replace the strainer.
Place the strainer in the cavity. Clean the coverplate and O-ring.
Coat the O-ring lightly with grease. Ensure the coverplate O-ring
is properly seated and tighten the strainer coverplate.
If the pump is to be installed in a Hazardous (Classified)
location, it must be installed by a licensed electrician and
conform to National Fire Protection Association (NFPA)
codes 30 and 70. You as the owner, are responsible for
seeing that the installation and operation of your pump
complies with NFPA codes as well as any applicable
state and local codes. Rigid conduit must be used to
install wiring. Note that the lead wires are factory-sealed
isolating the motor from the junction box.
Failure to follow these wiring instructions may result in
death or serious injury from shock, fire or explosion.
Install Hose and Nozzle
After sealing the 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.
The nozzle holder allows the pump to be locked when the
nozzled is in place.
ALWAYS FOLLOW SAFETY PRECAUTIONS WHEN
OPERATING THIS EQUIPMENT. REVIEW THE SAFETY
INSTRUCTIONS. 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.
Dispense Fuel
Turn the pump on by removing the nozzle from its holder and
pushing up the switch lever. Insert the nozzle into the receiving
tank and squeeze the handle to start fuel flow. When done,
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 delivered
within 15 to 20 seconds, turn the pump off and refer to the
priming information in the Troubleshooting Section.
An automatic bypass valve prevents pressure buildup when
the pump is on with the nozzle closed. To avoid pump dam-
age, do not run the pump for more than 10 minutes with the
nozzle closed.
Motor Protector (Models M-150S and M-180S only)
The pump contains a motor protector that provides added
protection against motor damage. It must be reset manually.
If the motor protector trips, reset by turning the switch OFF. Let
the pump cool then turn ON again. If the motor protector trips
again, see the Troubleshooting Section of this manual.
