EMAX Gas Powered, Piston Compressors
Inspect belt tension after first 30 hours of operation
then every 30 days.
1. Proper belt tension is determined by pressing
on belt midway between motor pulley and
flywheel. There should be approximately 1/2
inch of deflection. See figure 4, pg. 7.
2. Loosen motor (4) mounting bolts, found
underneath motor mount bracket. Slide
motor in bracket slots as needed for proper
tension. See figure 6. Be sure motor shaft
and pulley are aligned properly with pump
befor tightening motor bolts and restart-
ing unit.
3. Always replace all belts with the same brand,
at the same time. Make sure belts are uni-
matched. Do not replace belts independently.
4. Do not splash lubricating oil on belts or pul-
leys when adjusting or replacing belts.
Changing Oil
All units are shipped with break-in oil. Change oil
within first 30 hours or 10 days of operation, which-
ever comes first. DO NOT use automotive type oil.
Use only Airbase Industries oil
(PN: APOL03000G1). Use of any
other product will cause product damage and void
the warranty.
Change oil every 90 days or if oil becomes milky.
High humidity and excessive temperature changes
can cause moisture to form in the pump. This mois-
ture will cause oil to break down and become milky.
Be sure to check oil regularly for proper lubrication.
Make sure to dispose of used parts such as oil and
filters in accordance with all applicable regulations.
7. Start engine by turning key or with pull start
cord.
If ignition fails to start engine
after 5 seconds, release key and
wait 10 seconds before trying again. Continuously
trying to crank starter can overheat and damage
starter motor.
8. After engine starts, move choke lever to run
position.
9. Allow engine to warm up then turn pressure
relief knob to run position.
10. Keep ball valve open for approximately 20-30
minutes before initial use to allow for pump
break-in period. Be sure to close ball valve for
unit to build pressure for proper operation.
Maintenance
Safety Steps
Disconnect, tag and lock out power
source then release all pressure from
the system before attempting to
install, service, relocate or perform
ANY maintenance.
1. Make sure repairs are done in a clean, dry,
well lighted and ventilated area.
2. Disconnect engine spark plug wire before
performing any maintenance or repairs.
3. When cleaning, use air pressure less than 30
psig (2.1bar). NEVER use flammable solvents
for cleaning purposes. Also use effective chip
guarding and personal protective equipment
per OSHA standard 29 CFR 1910.242 (b).
4. Relieve all internal pressure prior to opening
any line, fitting, hose, valve, drain plug, con-
nection or other component, such as filters
and line oilers, and before refilling optional
air line anti-icer systems with antifreeze
compound.
Compressor components can
become hot during operation.
Avoid bodily contact with hot
liquids, hot surfaces and sharp
edges and corners.
Belt Adjustment
Be sure to relieve all system
pressure then lock out power and
tag compressor to prevent
unexpected movement of the unit.
