V1.1 9 Gallon Twin-Tank Wheelbarrow Portable Air Compressor 9041559

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

secure position that keeps it from tipping or falling during use.

b. Do not operate without an air filter or in a corrosive environment.

c. Always transport in a level position and use protective mats to

keep truck beds clean, etc. Fasten the compressor down securely.

Pressure must be released from the tank before transporting.

d. In cold climates, drain the tank after each use to avoid ice buildup.

8. Air supplied to the inlet filter must be clean. The compressor belt guard

must not be located closer than 12 inches to a wall, or 24 inches to

another compressor. Additional safety can be achieved by locating the

pulley drive system, with the guard, next to the wall.

9. Never use this compressor to inflate low pressure objects (i.e. toys,

footballs, etc.).

10. Do not replace the safety valve with a plug.

11. Do not install a shutoff valve in the compressor discharge line without

first installing a safety valve of proper size and design between the

shutoff valve and the compressor.

12. Periodically check all safety valves for proper operation. Safety valves

aid in preventing system failures by relieving system pressure when

compressed air reaches a pre-determined pressure level.

a. Do not attempt to tamper with safety valve. Anything loosened

from this device could fly up and hit you. Failure to heed this

warning could result in death or serious personal injury.

13. Do not move the compressor while in use.

14. Check the manufacturer’s maximum pressure rating for air tools and

accessories. Compressor outlet pressure must be regulated to never

exceed the maximum pressure rating of the tool (see Specifications).

Exceeding the maximum PSI rating can create a bursting hazard,

causing injury and property damage.

15. Serious injury may occur from loose debris being propelled at high speeds

from the compressed air stream. Always wear OSHA approved safety

glasses to protect the eyes during operation of the air compressor.

16. Always turn off the air compressor and drain tank pressure completely

before attempting maintenance or attaching air tools. Release pressure

slowly from the system.

BEFORE FIRST USE

1. Check that all screws are tight.

2. Check that the tension rods are tight (see Care & Maintenance –

Month). This must be done again after the first hour of use.

3. When starting an engine driven unit with air pressure in the tank, flip

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.

9041559 9 Gallon Twin-Tank Wheelbarrow Portable Air Compressor V1.1

exist, stop the compressor and refer to Troubleshooting.

8. Allow the compressor to run for a few minutes.

9. Close the petcock (turn counterclockwise).

10. Flip the toggle on the pilot valve to the ‘RUN’ position. The compressor

should pump up the tank to 135 PSI, then unload. If pressure exceeds

135 PSI, see Troubleshooting.

11. To stop the compressor, shut the engine off.

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.

6. Maintain the tool’s labels and name plates. These carry important

information. If unreadable or missing, contact Princess Auto Ltd. for

replacements.

a. Do not operate this tool if it does not contain a legible warning label.

V1.1 9 Gallon Twin-Tank Wheelbarrow Portable Air Compressor 9041559

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.

3. Give compressor overall visual inspection and be sure safety guards

are in place.

4. Check for any unusual noise or vibration.

5. Check for leaks.

WEEK LY

1. Check all pressurized components for rust, cracking or leaking. Immediately

discontinue use of the equipment and relieve all system pressure if any of

these problems are discovered. Do not use the equipment until it has been

inspected and repaired by a qualified mechanic.

2. Clean the exterior surfaces of the compressor.

3. Check the air filter and replace if necessary.

MONTHLY

1. Check belt tension.

a. In order to adjust the drive belt, the

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.
