SYSTEM CONTROLS
(1) SAFETY-RELIEF VALVE Every ROLAIR®air compressor is equipped with a safety-relief valve which is designed to discharge
tank pressure at a predetermined setting when a systems failure occurs. Check the safety valve periodically by pulling on the ring
only when the tank pressure is completely drained. The spring loaded valve should move freely within the safety valve body. An
inoperable safety valve could allow an excessive amount of tank pressure to build causing the air tank to catastrophically rupture
or explode.
Do not tamper with or attempt to eliminate the safety relief valve.
(2) MANUAL OVERLOAD / MOTOR RESET Every ROLAIR® electric air compressor is built with manual overload protection. If the
motor overheats, the overload sensor will trip the reset button to protect the motor. If this occurs, please allow the motor to cool
for approximately five minutes. Locate and push in the reset button. The use of an undersized or excessive length of extension
cord may be the cause of overheating. Re-evaluate the power source and gauge/length of extension cord being used. (Refer to
chart on page 8)
(3) PRESSURE SWITCH Most electric air compressors are operated by the use of a pressure switch. Always make sure the lever
is in the “Off” position before plugging in the power cord. By moving the lever to the “On/Auto” position, the compressor will start
and stop automatically within the settings of the pressure switch which are typically 105 – 130 PSI. Do not attempt to stop the
compressor by unplugging the power cord. To stop, simply move the lever to the “Off” position. The lever operates a relief valve
that dumps off head pressure and allows the compressor to restart without load the next time it is used.
(4) REGULATOR – WORKING PRESSURE To adjust the output/line pressure, simply lift up on the regulator adjustment knob and
rotate clockwise to increase working pressure or counterclockwise to decrease. Push adjustment knob back down to lock in
setting. Never exceed the manufacturer’s maximum allowable pressure rating of the tool being used or item being inflated.
(5) PRESSURE GAUGE(S) Typically, most compressors are designed with a gauge to measure tank or storage pressure and
another gauge attached to the regulator that indicates output or working pressure.
(6) DRAIN VALVE(S) One or more drain valves are installed to allow moisture to be drained on a daily basis from the compressor
storage tank(s). Open drains carefully and slowly to prevent scale, rust, or debris from becoming expelled at a high rate of speed.
(7) AIR INTAKE FILTER Air intake filters are installed to prevent foreign matter from entering the engine or compressor pump.
Check intake elements on a regular basis and either clean or replace as needed. Warm soapy water or low compressed air may
be used to clean the elements. Check intake canisters or elbow components for cracks or broken seals and replace if structural
problems are found.

SYSTEM CONTROLS
(con’t)
(8) PILOT-UNLOADER VALVE A pilot-unloader valve is used on all gas-powered units and can be used on electric air compressors
to operate in a continuous manner. When the storage tank reaches the top pressure setting of the pilot valve, the air being
compressed is discharged to atmosphere instead of into the storage tank. When the tank pressure drops to the low pressure
setting of the pilot valve, the compressed air will be redirected to the air tank. Do not attempt to replace the pilot valve without
first draining the tank pressure completely. See Figure 3 for adjustment and fine-tuning instructions. Do not adjust above the
following factory recommendations.
Classification Pressure Setting
Direct Drive Compressor 105-130 PSI
I-Stage Compressor 110-135 PSI
II-Stage Compressor 130-150 PSI
(9) SIGHT GAUGE/DIPSTICK Prior to daily operation, make a habit of checking the oil level of the compressor pump and engine (if
compressor is gas powered). Every direct-drive hand-carry air compressor has a dipstick to help check and maintain the proper oil
level. The dipstick also functions as a crankcase vent. Never operate a direct-drive unit without the factory-supplied dipstick. Our
belt-driven air compressors are equipped with a sight gauge to make the daily task of checking the oil level easier. Always
maintain the oil level to read 2/3 full on the sight gauge.
(10) CHECK VALVE Every ROLAIR® air compressor is built with a check valve to seal off and maintain tank pressure after the top
end pressure setting of pilot valve or pressure switch is reached. The check valve works in conjunction with the pressure switch
relief valve to provide a loadless start for the compressor system. A quick burst of air escaping from the pressure switch relief
valve after an electric unit reaches top end indicates the check valve is working properly. If the compressor has a mysterious leak
after stopping that cannot be traced elsewhere, the check valve may require servicing/replacing.
(11) BREATHER/OIL FILL PLUG All reciprocating air compressor pumps are built with a crankcase vent to relieve the pressure
that is created by the downward movement of the piston in the pump cylinder. Our direct-drive air compressors vent the
crankcase pressure through special ports in the dipstick. Our belt-drive units vent through the oil-fill plug. Never operate the air
compressor without the dipstick or oil-fill plug.
(12) AUTOMATIC-IDLE CONTROL Every ROLAIR® gas-powered air compressor is built with an engine idle control kit that
automatically decreases the engine speed when the top end pressure setting of the pilot unloader valve is reached. The top RPM
setting of the engine is factory set for maximum performance and service life. Do not alter the factory top RPM setting. The engine
idle speed is factory set and controlled by a black plastic Philips head screw on the carburetor. A slight increase to the idle speed
setting may be required when operating in colder temperatures. Turn screw clockwise in 1/4 turn increments to increase the idle
speed. If the idle speed setting is too low, premature fouling of spark plug will occur.
(13) COLD-START VALVE Most ROLAIR®direct-drive air compressors are built with an automatic cold-start valve that allows the
motor/pump to warm up before being subjected to tank pressure. Our belt-driven portable units have a manual drain valve
installed on the pump aftercooler to assist with cold weather starting. Open drain valve and allow the motor and pump to run
unloaded for a minute to warm up. Close the drain and repeat the procedure if the motor or engine continue to struggle.
(14) SCHMIDT BELT-TIGHTENING DEVICE (FOR GAS UNITS ONLY) Every ROLAIR®gas-powered belt-driven portable air compressor
has a unique system for maintaining proper belt tension. Simply loosen the 1/2” locknuts (only until washers beneath spin freely)
that secure the engine and rotate the fine thread bolt located on the wheel end of the base plate clockwise until the desired belt
tension is achieved. (See drawing in section on operating instructions for proper tension) Re-tighten 1/2” locknuts to secure engine
and maintain desired belt tension setting.
(15) VIBRATION DAMPENER(S) The rubber pads installed beneath every portable ROLAIR®tank assembly are very important to
the proper operation of the air compressor. They provide protection from vibration that left unchecked could cause damage to
many system components.
(16) ENGINE KILL SWITCH A kill switch is installed to easily stop the engine. Do not attempt to move the throttle lever (as
described in the Honda owner’s manual) when stopping the engine. The engine throttle lever is factory set and locked down at a
top RPM setting that will provide maximum performance and service life for the complete air compressor system. The kill switch
must be moved to the “On” position prior to pulling the recoil rope assembly to start the engine.
(17) ENGINE CHOKE Moving the choke lever completely to the left (closed position) will help start a cold engine. Also see
instructions for cold-start valve (Item #13). After start up, the choke lever must be moved completely to the right (open position)
for the engine to operate properly. Fouling of spark plug and excessive internal carbon build up will occur if engine is operated
with choke lever even partially closed.
(18) FUEL SHUT-OFF VALVE The fuel shut-off valve should only be moved to the “Open” position (completely to the right) when
the engine is being operated. Always stop the flow of fuel by moving the shut-off valve completely to the left when the engine is
not being operated. Do not move or transport the air compressor with the fuel valve in the open position.

PRE-START CHECKLIST
Read the owner’s manual thoroughly. Make sure that you completely understand all of the safety warnings,
system controls and instructions provided before attempting to operate this air compressor. Every effort has been
made to provide you with the information needed to obtain many years of reliable and trouble-free service out of
your new air compressor. It is your responsibility to operate the air compressor properly. To obtain the longest
possible service life from your air compressor you must always keep the following instructions in mind.
1. ALWAYS OPERATE THE COMPRESSOR IN A LEVEL POSITION
All splash-lubricated pumps have a dipper on the bottom of the connecting rod that must remain submerged in
the oil bath. Operation at more than a 10 degree angle will cause the pump to seize and void the product
warranty
2. OPERATE IN A CLEAN, DRY AND WELL VENTILATED AREA
Allow at least 18” behind the belt guard for proper cooling of pump from flywheel blast. Do not operate in the rain
or in areas of standing water. Never operate in an area where other gases, fumes or vapors are present which
may become explosive when compressed. Do not operate compressor in an enclosed area.
3. CHECK OIL LEVEL DAILY AND CHANGE AT REGULAR INTERVALS
Refer to the maintenance section of this owner’s manual for the correct type/weight of oil to use and how often
the oil should be changed. Check oil levels daily.
4. INSPECT/CLEAN/CHANGE INTAKE ELEMENTS ON A REGULAR BASIS
The ingestion of dirt into the pump and engine is the primary cause of premature wear. Pay special attention to
the intake filters. Check intake filters daily.
5. USE LONGER, PROPERLY SIZED AIR HOSE RATHER THAN EXTENSION CORDS
If an extension cord must be used, please refer to the chart below for the proper gauge and maximum length that
can be used. The use of inadequately sized air hose will also lead to frictional pressure drops that could affect the
proper performance of your air tools.
6. DO NOT USE A GENERATOR AS THE POWER SOURCE
Air compressors use inductive motors that require 3-5 times the full-load amp draw to properly start. Most
generators will not provide the wattage needed to properly start this type of electric motor.
7. CHECK TENSION OF BOLTS, BELTS, AND HARDWARE ON A REGULAR BASIS
Operation of any equipment with loose bolts and/or fittings will lead to excessive vibration
and the premature failure of the compressor system control components.
8. MAINTAIN RUBBER VIBRATION PADS
Excessive vibration is a major cause of premature compressor failure. Always maintain the rubber vibration pads
located beneath tank assembly. Operation without them will void your warranty.
9. DRAIN MOISTURE FROM AIR TANKS DAILY
Water is a natural byproduct of compressed air. Drain air tank(s) after each use to combat internal tank corrosion.
Keep drain valve(s) closed if storing compressor for any length of time.

OPERATION
WARNING – Your safety and the wellbeing of others during the operation of every ROLAIR®compressor is our main
concern. Do not operate or permit anyone else to operate your air compressor until the information contained in this
manual is read and completely understood. Please contact your distributor or our customer service department if you
have any questions on the proper use of your air compressor.
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.
BELT-DRIVE ELECTRIC
START/STOP OPERATION:
Follow same procedures described above for use of direct-drive
electric compressors. Open drain valve located on pump aftercooler for
cold starting purposes. An electric belt-driven motor should not be
subjected to more than 15 starts per hour. Consult your dealer or any
authorized ROLAIR®service center for information on a conversion kit if you
experience nuisance tripping of the motor overload due to an excessive
amount of motor starts per hour.
CONSTANT-SPEED OPERATION:
Constant speed or continuous-running operation should be used
during periods of heavy use to extend motor life and prevent overheating.
If your machine is built to only operate continuously, special care must
be taken to safely start and stop the machine. Always shut off the
power to the electrical outlet at the main breaker or optional on/off
switch before plugging in or unplugging the power cord. We also highly
recommend complete draining of storage tank(s) and opening of aftercooler drain valve prior to starting, especially
when operating in cold temperatures. Never stop the compressor by pulling the plug from the outlet. Use the
breaker or optional on/off switch to shut off the power to the outlet first.
DUAL-CONTROL OPERATION:
Dual controls allow an easy transition between start/stop and continuous-running operation. See figure 1 for
instructions to switch operation from start/stop to constant speed. Always flip the lever on the pressure switch to the
“off” position before plugging in or unplugging the power cord.
DUTY CYCLE:
All ROLAIR®belt-driven air compressors are equipped with S1 or 100% duty cycle motors and pumps. Given
proper ventilation and electrical power, your ROLAIR®compressor is capable of operating continuously when set up
for constant speed operation. However, an excessive amount of starts per hour may generate enough heat to trip the
motor overload. Please contact our factory Customer Service Department if overload problems repeatedly occur.
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.
GAS POWERED
Refer to item numbers 12, 16, 17 & 18 in the “System Controls” section of this manual for information on the
engine automatic idle control, kill switch, choke and fuel shut-off valve. Also note the engine throttle arm is locked
into a top RPM setting that will provide maximum service life and does not need to be moved to start or stop the
machine. Additional instructions can be found in the engine owner’s manual. Use the drain valve located on the
pump aftercooler or intercooler for cold-starting purposes. Take additional care to keep dirt/debris from entering the
fuel tank or obstructing the air flow through the engine or past the pump. Make sure the air flow to the regulator is
completely closed (gauge attached reads 0 PSI) before attaching air hose and accessory. A slight
hissing noise caused
by the air flow being directed to atmosphere during engine idle is normal. Store compressor in a warm/dry location
and perform maintenance as indicated in your manuals.

- 10 -
OPERATION
(con’t.)
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. Carburetors on gas-powered air compressors may also need to be rejetted to perform properly
at higher elevations. Contact our factory Customer Service Department if your normally reliable air compressor fails
to operate correctly at higher elevations.
MAINTENANCE
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: 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) Move motor 1/4" and roll belts back on to increase
belt tension on electric units.
5) Never weld on air tank(s).
6) Use heat to loosen Loctite seal on drain valves, engine
pulleys, and flywheels before attempting to remove.
OIL CHART
LUBRICATION
Prior to each use, make a habit of checking the pump oil level. Most
direct-drive air compressors have a dipstick with casting marks that indicate
the minimum and maximum acceptable levels of oil. Our belt-driven pumps
have a sight gauge, located on the outside of the crankcase, to make the task
even easier. Always maintain the oil level at the maximum mark on the
dipstick or to 2/3 full in the sight gauge
Do not operate the pump with an inadequate or excessive amount of
oil. The cost of failures which occur due to incorrect oil levels will not be
covered under warranty.
DO NOT USE A DETERGENT OIL!
NOTE: Unit must be level when in operation

PILOT VALVE ADJUSTMENT
RESETTING DIFFERENTIAL (2)
Make sure the top toggle lever is positioned as shown. (See Figure 3). Loosen
locknut (1) by turning counterclockwise several full turns. Gently turn differential setting (2)
clockwise only until the internal rod makes contact with the steel ball inside. After making
contact, turn differential (2) counterclockwise 1/4 turn. Secure position by tightening locknut
(1) and proceed to top end setting.
TOP-END SETTING (4)
Loosen locknut (3) by turning counterclockwise several full turns. (4) is the top end
setting. Turning (4) clockwise will increase the top end pressure setting. Turning
counterclockwise will decrease the top end pressure setting. Begin at a low setting by
turning counterclockwise one full turn. Proceed to fine tuning instructions.
FINE-TUNING INSTRUCTIONS
Start engine/motor and observe tank pressure gauge. As tank pressure approaches
100-130 P.S.I.G., the pilot valve should begin unloading at felt muffler and cause gas engine
to slow down to idle speed. If pilot valve does not unload as tank pressure approaches 130
P.S.I.G., slowly turn top end setting (4) counterclockwise until pilot starts to unload
prematurely (at 100 P.S.I.G.), turn top end setting (4) clockwise in 1/4 turn increments, tap
down on the internal rod at toggle attachment and repeat until desired top end setting is

COMMANDES DU SYSTÈME
(1) SOUPAPE DE SÛRETÉ ET DE DÉCHARGE Chaque compresseur d'air ROLAIR®est muni d'une soupape de sûreté et de décharge
qui est conçue pour refouler la pression du réservoir à un réglage prédéterminé lorsque se produit une défaillance du système.
Vérifier périodiquement la soupape de sûreté en tirant sur l'anneau uniquement lorsque la pression du réservoir est
complètement purgée. La soupape à ressort doit se déplacer librement dans le corps de la soupape de sûreté. Une soupape de
sûreté hors service pourrait laisser s'accumuler une pression excessive dans le réservoir qui entraînerait son éclatement ou une
explosion.
Ne pas modifier ni tenter de retirer la soupape de sûreté.
(2) BOUTON DE RÉINITIALISATION DE SURCHARGE/MOTEUR Chaque compresseur d'air électrique ROLAIR®est muni d'une
protection manuelle contre la surcharge. Si le moteur surchauffe, le capteur de surcharge déclenchera le bouton de
réinitialisation pour protéger le moteur. Si ceci se produit, veuillez laisser le moteur refroidir pendant environ cinq minutes.
Localiser le bouton de réinitialisation et appuyer dessus. L'utilisation d'une rallonge de calibre insuffisant ou qui est trop longue
pourra être cause de surchauffe. Réévaluer la source d'alimentation, le calibre et la longueur de la rallonge utilisée. (Consulter le
tableau à la Page 8)
(3) PRESSOSTAT La plupart des compresseurs d'air électriques sont munis d'un pressostat. Toujours s'assurer que le levier est à
la position « Off » (arrêt) avant de brancher le cordon d'alimentation. En déplaçant le levier à la position « On/Auto »
(marche/automatique), le compresseur démarre et s'arrête automatiquement en fonction des paramètres du pressostat qui est
généralement entre 105 et 130 lb/po2. Ne pas tenter d'arrêter le compresseur en débranchant le cordon d'alimentation. Pour
arrêter, déplacer simplement le levier à la position « Off » (arrêt). Le levier active une soupape de refoulement qui libère la
pression à la tête et permet au compresseur de redémarrer sans charge lors de l'utilisation suivante.
(4)RÉGULATEUR – PRESSION DE FONCTIONNEMENT Pour régler la pression de sortie/de la conduite, lever simplement le
bouton de réglage du régulateur et le tourner dans le sens horaire pour augmenter la pression de fonctionnement ou dans le sens
antihoraire pour la diminuer. Enfoncer le bouton de réglage vers le bas pour verrouiller le paramètre. Ne jamais dépasser les
puissances nominales admissibles, maximales, du fabricant et de l'outil qui est utilisé ou de l'objet qui est gonflé.
(5) MANOMÈTRE(S) En règle générale, la plupart des compresseurs sont munis d'une jauge pour mesurer la pression du
réservoir ou de stockage et une autre jauge fixée au régulateur qui indique la pression de sortie ou de fonctionnement.
(6) SOUPAPE(S) DE PURGE Une ou plusieurs soupape(s) de purge est ou sont installée(s) pour évacuer, quotidiennement,
l'humidité du ou des réservoir(s) de stockage du compresseur. Ouvrir les soupapes de purge lentement et avec précaution pour
éviter que le tartre, la rouille, les débris soient projetés à une vitesse élevée.
(7) FILTRE D'ADMISSION D'AIR Des filtres d'admission d'air sont installés pour empêcher les corps étrangers de pénétrer dans le
moteur de la pompe ou du compresseur. Vérifier les éléments d'admission sur une base régulière et soit nettoyer ou remplacer,
le cas échéant. De l'eau tiède savonneuse ou de l'air comprimé de faible pression pourra être utilisé(e) pour nettoyer les
éléments. Vérifier les bouteilles d'admission ou les éléments du coude pour la présence de fissures ou de joints brisés et les
remplacer si des problèmes structurels sont détectés.
