If the pump is to be installed in a Hazardous (Classified) location,
it must be installed by a licensed electrician and conform to Na-
tional 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
All threaded fuel connections must be sealed with thread
tape or a pipe thread sealing compound approved for
use with petroleum fuels.
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 nozzle is in place.
OPERATION
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 down on the switch lever. Insert the nozzle
into the receiving tank and squeeze the handle to start
fuel flow. When done, release the nozzle handle.
After dispensing fuel, pull the front end of the switch le-
ver up to turn the pump off and return the nozzle to the
holder. The nozzle may be locked in place to prevent
unauthorized use by installing a padlock (not provided)
through the hole in the top of the nozzle cover.
The 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 damage, do not run the pump for more than 10
minutes with the nozzle closed.

Motor Protector
This pump is equipped with a motor protective device
that also serves as the ON / OFF switch.
NOTE: The motor protective device is not intended to
provide branch circuit protection.
• If motor is overloaded, the protective device trips and
opens the circuit. This feature protects the motor from
damage and must be reset manually.
• To reset, turn the switch lever off and then back on.
• If the protective device trips again quickly, turn the
power off at the source before attempting to trouble-
shoot the problem. Follow instructions as described
in the Troubleshooting Section of this manual.
• Make sure the switch lever is off before restoring
power.
• Turn the switch lever on and restart.
MAINTENANCE
This pump is designed for minimum maintenance. Motor
bearings 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 condi-
tion. 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 unauthor-
ized fluids will void the warranty.
To Clean or Replace Strainer
All pump models have an inlet strainer. If flowrate is
reduced, clean or replace strainer (see below).
