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
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.

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
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.
