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 uid other than those listed in this manual
will damage the pump. Use of the pump with unauthor-
ized uids 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 inspect 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

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.

REPAIR
Carefully inspect all parts for wear or damage. Replace
components, as necessary. The Illustrated Parts List
gives information on replacement parts and kits.
Review the Safety Instructions before proceeding.
Observe precautions against electrical shock when servicing
the pump. Always disconnect power before repairing or servic-
ing. Never apply electrical power to the system when any of the
coverplates are removed.
Avoid prolonged skin contact with petroleum fuels. Use protective
goggles, gloves and aprons in case of splashing or spills. Change
saturated clothing and wash skin promptly with soap and water.
WARNING
If the pump is to be installed in a Hazardous (Classied) loca-
tion, 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, re or explosion.
DANGER
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.
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 up the switch lever. Insert the nozzle into
the receiving tank and squeeze the handle to start fuel
ow. 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 damage, 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.
