Dispensing Fuel
1. Remove the nozzle from holder and insert into receiving tank. Turn the
pump on by pushing the switch lever up. Squeeze the handle to start
fuel flow. When done, release the nozzle handle, turn the pump off, and
return the nozzle to its holder.
IMPORTANT: 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 priming
information in the Troubleshooting Section.
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. Leaving the
pump on with the nozzle closed for more than 10 minutes can damage the pump
components and will void the warranty.
Never leave the pump running without fluid.
Dry running can damage the pump components, and will void the warranty.
IMPORTANT: This is an intermittent duty pump, after running the pump
for a maximum of 30 minutes, allow it to cool for 30 minutes.

Motor Protector
This pump is equipped with a thermal device that will automatically turn the
pump OFF if it gets too hot.
If the pump automatically shuts off after 30 minutes of use, turn the switch OFF
and allow the motor to cool for 30 minutes. After adequate cooling, the pump is
ready for use again.
NOTE: The motor will automatically restart after a short amount of cooling time if
the switch is not turned off; in this case it is likely to overheat again well short of
the 30 minute duty cycle if not allowed to cool for the full 30 minutes.
