Visit www.princessauto.com for more information 5
a. Serious injury or death may occur from an air tank explosion if the
air tank is not properly maintained or if modifications, alterations or
repairs are attempted. Drain air tank daily or after each use. Never
drill into, weld, patch or modify the air tank. Replace the tank
immediately or replace the entire compressor, if a leak develops.
b. Serious injury or death may occur if modifications are made to the
pressure switch, safety relief valve or other components that
control the tank pressure. Never make adjustments to the
components that control tank pressure. Do not make alterations
to the factory operating pressure settings. Check operation of the
pressure relief valve on a regular basis and never operate without
a factory approved pressure relief valve.
c. Check the manufacturer’s maximum pressure rating for air tools
and accessories. Compressor outlet pressure must be regulated so
as to never exceed the maximum pressure rating of the tool.
4. Risk of Explosion or Fire
Serious injury may occur if a fire is caused by overheating due to
inadequate ventilation or restrictions to any of the compressor’s
ventilation openings. Never place objects against or on top of an air
compressor. Always operate air compressor at least 12 in. away from
any wall or obstruction. Always operate in a clean, dry and well-
ventilated area.
5. Risk of Burn
Serious burn injuries could occur from touching exposed metal parts such
as the compressor head or motor during operation and even after the
compressor is shut down for some time. Never touch any of the exposed
metal parts during operation and for an extended period of time after the
air compressor has shut down. Do not attempt maintenance on the unit
until it has been allowed to completely cool.
6. Risk from Moving Parts

the pilot valve’s (D) toggle to the horizontal position. This will unload
the compressor and allow the engine to start easier.
4. When the engine has run for a few minutes, flip the toggle back to its
original position.
5. New compressors should be run with approximately 80 PSI of air
pressure in the tank for 1 hour to break-in (use regulator to control
tank pressure). This will allow the compressor time to warm up and
seat the rings.
PRE-START CHECKLIST
CHECK SAFETY VALVE
DANGER! If air leaks after the ring has been released, or if the valve is stuck
and cannot be actuated by the ring, do not use the air compressor until the
safety valve has been replaced. Use of the air compressor in this condition
could result in the tank bursting causing serious personal injury or death.
See Specific Safety Precautions: Bursting.
1. Turn the air compressor on and allow the air tank (G) to fill to 30 PSI.
2. Turn the air compressor off.
3. Pull the ring on the safety valve (E) to release air for twenty seconds.
4. Release the ring. Air must immediately stop escaping when the ring is
released. Any continued loss of air after releasing the safety valve ring
indicates a problem with the safety valve. Discontinue use and seek
service before continued use of the air compressor.
BEFORE EACH USE
WARNING! Never assume a compressor is safe to work on just because it is
not operating. It could restart at any time.
1. Make sure that the compressor is turned off.
2. Check the lubricant level (see Lubrication).
3. Make sure all safety valves are correctly installed.

USING THE COMPRESSOR
WARNING! Always ensure the regulator pressure gauge reads zero before
changing air tools or disconnecting the hose from the air outlet. Failure to
do so could result in possible serious personal injury. Run the tool to
depressurize the system.
Your tool may require more air consumption than this air compressor is
capable of providing. Check the tool manual to avoid damage to the tool or
risk of personal injury.
Always use the minimum amount of pressure necessary for your
application. Using a higher pressure than needed will drain air from the tank
more rapidly and cause the unit to cycle on more frequently.
9041559 9 Gallon Twin-Tank Wheelbarrow Portable Air Compressor V1.1
12 For technical questions call 1-800-665-8685
1. Attach the air hose to the air outlet (J).
2. Rotate pressure regulator knob (M) to the desired line pressure. Turning
the knob clockwise increases air pressure at the outlet; turning
counterclockwise reduces air pressure at the outlet.
a. If using an inflation accessory, control the amount of air flow with
the pressure regulator knob.
3. Always shut off the engine when the task is finished. Never leave the
compressor running while unattended.
4. Completely relieve the system of air pressure by pulling the ring on the
safety valve. Position yourself so that the expelled moisture and air is
not blown towards you. Continue to pull the ring until all air pressure
escapes. Depressurize the tanks completely.
5. Drain moisture from each air tank using the drain valve (K and L)
located on the underside. Only do this when the tanks pressure is 10
PSI or lower. Position the compressor so that the drain valve is lower
than the rest of the air tank. Drain until all moisture is removed. Leave
the valves open until the tanks have time to dry.
6. Disconnect the air hose from compressor and hang the open ends
down to allow any moisture to drain.
7. Store the compressor and hose in a cool, dry place.
CARE & MAINTENANCE
Consult the Gas Engine manual for engine maintenance instructions.
1. Maintain the tool with care. A tool in good condition is efficient, easier
to control and will have fewer problems.
2. Inspect the tool fittings, alignment, hoses and power supply cord
periodically. Have damaged or worn components repaired or replaced
by an authorized technician. Only use identical replacement parts
when servicing.
3. Follow instructions for lubricating and changing accessories.
4. Only use accessories intended for use with this tool.
5. Keep the tool clean, dry and free from oil/grease at all times.

Visit www.princessauto.com for more information 13
7. The compressor may only be operated in temperatures under 104°F and
over 32°F. In cold climates, the compressor should be installed in a
heated building.
8. Fill the compressor pump with oil (see Lubrication).
9. Fill the fuel tank with fuel.
10. Rust can form inside the crankcase and on internal components as a result
of condensation. A compressor must operate long enough during each run
cycle to reach full operating temperature in order to reduce the risk of
condensation.
11. Condensation can also form in the air tank of your compressor. When this
happens, a mixture of air and moisture will be expelled through the
service valve and into whatever is connected to the valve (e.g. air hoses,
metal air lines, pneumatic tools, spray guns). An in-line filter, may be
required to eliminate the moisture.
12. Drive pulleys and compressor flywheels must be properly aligned and
tensioned to specifications.
WARNING! Only qualified service personnel should repair the tool. An
improperly repaired tool may present a hazard to the user and/or others.
CLEANING
1. Always use a clean cloth. Never use brake fluids, gasoline, petroleum-
based products, or any strong solvents to clean the unit. Doing so
could risk deterioration of the enclosure plastic.
2. Clean the intake filter every 100 hours in service. The intake filter
prevents dust and dirt from being drawn in and a clogged intake filter
will decrease performance. To clean the intake filter:
a. Remove the two hex screw from the air intake filter (B) cover.
b. Remove the filter from the two halves of the plastic housing, tap it
to remove the dirt, blast it down with low-pressure compressed
air (approx. 43 PSI) from inside of the filter to remove fine
particles and re-insert it.
MAINTENANCE SCHEDULE
WARNING! Some surface temperatures exceed 350°F when the unit is
operating. Do not touch as it may cause a burn injury. Wait for the unit to
cool before starting to service.
9041559 9 Gallon Twin-Tank Wheelbarrow Portable Air Compressor V1.1

WARNING! Before servicing, always shut off the engine and remove the
spark plug wire. Release all air from the tank by pulling the ring on the
safety valve until all air pressure escapes. Failure to depressurize tank
before maintenance may cause serious personal injury.
WARNING! Never attempt to relieve air pressure in an air tank by removing
a pipe plug or any other system component.
HOUR METER
The hour meter records the engine and compressor’s running time to assure
required maintenance is performed on schedule.
Refer to the gas engine owner’s manual for maintenance procedures to be
performed on the engine. If the unit is used in an excessively dirty or dusty
environment, check and perform all maintenance procedures more often.
AFTER FIRST 100 HOURS OR FIRST MONTH OF OPERATION
Replace break-in lubricant with SAE 40W oil (see lubrication).
DAILY
1. Maintain the lubricant level at the halfway point on the sight glass.
Discolored lubricant or a higher lubricant level reading may indicate
the presence of condensed liquids (see Troubleshooting).
2. Humidity in the air causes condensate to form in the air tank. Drain
moisture from air tank(s). Tank(s) subjected to freezing temperatures may
contain ice. Store the compressor in a heated area before attempting to
drain moisture from the tank(s). To drain moisture from the air tanks:
a. Turn the air compressor off and allow air compressor to become
cool to the touch before servicing. Turn pressure regulator knob
fully counterclockwise.
b. Completely relieve the system of air pressure by pulling the ring on
the safety valve (E). Position yourself so that the moisture and air
being expelled does not touch you. Continue to pull the ring until all
air pressure escapes.
c. Drain moisture from the air tanks using the drain valve located on
the underside of each air tank. Tilt the compressor in the direction
of the drain valve into a suitable container until all moisture has
been removed. If unit will not be used for a while, leave drain valve
open to allow moisture to completely drain out and help prevent
corrosion on the inside of tank. Otherwise, close valve completely.
d. If drain valve is clogged, remove and clean valve and reinstall.

safety guard (P) must be removed.
b. Check the belt alignment by placing
a straightedge against the face of
the flywheel, touching its rim at two
places (Fig. 4).
c. Adjust the flywheel or motor pulley so that the belt runs parallel to
the straightedge. Use a puller to move the motor pulley on the
shaft. Properly adjusted, a 3 lb pressure applied to the belt between
the motor pulley and the compressor flywheel will deflect the belt
about 1/4 in. (6 mm).
d. To adjust the belt tension, loosen the four engine mounting screws.
Slide the engine in the proper direction, until the belt is tensioned to
the point where it can still be depressed by approx. 1/4 in. (6 mm) at
the longest free position. Re-tighten the engine
mounting screws and refit the safety guard for
the belt.
2. Check pulley retaining screws.
3. Check system for air leaks.
4. Check that all screws, bolts and nuts are tight.
