DIRECT-DRIVE ELECTRIC
Establish that the air compressor is ready to operate by reviewing the topics and information provided in the "Pre-Start
Checklist" section of this manual. Slowly open tank drain to remove any condensate that has accumulated and keep drain open for
a few seconds after starting to warm up motor/pump assembly. Make sure the pressure switch lever is in the "Off" position before
plugging power cord into a properly grounded outlet. Move pressure switch lever to the "On/Auto" position to build and
automatically maintain top end tank pressure setting. Rotate regulator adjustment knob counterclockwise until the gauge attached
reads 0 PSI before attaching air hose and accessory. Set working pressure by rotating regulator adjustment knob clockwise and lock
in working pressure according to specifications provided by the tool manufacturer. Always use the pressure switch "On(Auto)/Off"
lever to start or stop the air compressor. Never stop the compressor by unplugging it from the power source. Store compressor in a
warm/dry location and perform maintenance as indicated in manual.
DUTY CYCLE:
Several ROLAIR direct-drive machines, Models FC1500HBP2, FC1500HS3 and JC10, are rated for 70% duty cycle. If
subjected to continuous operation the internal overload will shut down the motor and only restart when sufficient cooling has
occurred.
FREEZING TEMPERATURES:
Proper fluid maintenance and warm up procedures are mandatory before attempting to start or operate an air compressor in
freezing temperatures. Water, a natural byproduct of compressed air, could turn into ice and potentially block air flow into,
though, and/or out of the pump, air tank(s), and air line(s). Drain air tanks/ lines after every use and leave drain valves open when
not in use.
If all, or part, of the compressor may be frozen, you must completely thaw the compressor before attempting to start. Gradually
increase the temperature above freezing and then drain moisture from the air tanks, intercoolers, and water traps.
Cold Weather Best Practices:
•
Do not attempt to start a frozen compressor. Thaw completely first.
•
Store your air compressor in a clean, dry area that stays consistently above freezing temperatures.
•
Change the oil in the pump and engine to winter grade (check owner's manual).
Prior to starting, open the tank drain(s) and allow the compressor to run for 45-60 seconds with the tank drain(s) open
•
before closing to build tank pressure.
Using a lubricator with de-icing fluid may also be needed to keep your air lines from freezing up/blocked by ice.
•
Contact your ROLAIR dealer or our factory customer service department if you have additional questions.

HIGH-ALTITUDE OPERATION:
Due to a decrease in atmospheric pressure air compressor pumps produce less CFM at higher elevations. As a rule of
thumb the output will decrease approximately three percent per 1000 feet of elevation. Also, because air at higher elevations is
less dense and does not cool as well, electric motors cannot be subjected to the full nameplate service factor amp rating and may
need to be upgraded to avoid repeated overheating.
Direct drive or hand-carry compressors built with cold-start valves may need to be modified when operated in higher
elevations. Contact our factory Customer Service Department if your normally reliable air compressor fails to operate correctly at
higher elevations.
Your new air compressor represents the finest engineering and construction available. Even the best machinery requires
periodic maintenance. Please stick to the maintenance schedule and consider the suggestions that follow to keep your compressor
in peak condition.
NOTE: Always unplug or shut down your compressor and drain the air tanks completely before attempting any type of
maintenance. Wait for compressor to cool before servicing.
IMPORTANT: Replace the oil after the first 50 hours of operation.
MAINTENANCE HINTS:
pulleys, and flywheels before attempting to remove.
OPERATION
MAINTENANCE
1) Use a soap/water solution to check for air leaks.
2) Never clean filters with a flammable solvent.
3) Retorque head bolts only after pump has cooled.
4) Never weld on air tank(s).
5) Use heat to loosen Loctite seal on drain valves, engine
