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 -
SYSTEM CONTROLS (con’t)
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.
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.

SYSTEM CONTROLS (con’t)
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.

- 9 -
PRE-START CHECKLIST (con’t)
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.

factory set and locked into position at RPMs that will provide maximum performance, fuel consumption
and service life. Alterations to this setting will void your warranty.
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.

- 10 -
OPERATION (con’t)
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 electric 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.
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.

- 11 -
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.
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

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 reached. If pilot valve begins to rifle (sputter), fine tune differential setting (2) 1/16 turn in either
direction until rifling stops. After fine tuning, secure setting by turning locknuts (1 & 3) clockwise until tight.
Hold setting (2 & 4) in place while turning locknuts to secure.

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.
