Description of Components
Compressor Assembly - The Auto Crane AC40 hydraulic drive piston compressor assembly is a positive
displacement, intermittent-flow, reciprocating unit. The piston compressor consists of a crankshaft, oil filter,
oil pump, four connecting rods, pistons, cylinders, and valve assemblies. As the crankshaft rotates, the
pistons move up and down. As they move down, a vacuum is created above the piston which allows the
reed valve to open and fill the area above the piston with air. When the pistons move back up, this air is
discharged from the compressor. Oil lubricates the bearings and cylinder walls as the crankshaft rotates,
ensuring that the system stays cool.
Hydraulic Oil Cooling Systems - The compressor cooling system consists of a hydraulic cooler mounted
on the compressor frame. Cool air is drawn through the vented end panel and flows over the compressor
surface and through the hydraulic cooler, exiting out the front vented panel . Allow for adequate clearance
(10”) for the air to exit. Also, the package location should not be subjected to air temperatures above
ambient.
Fluid Level Sight Glass - This sight glass indicates the fluid level in the crank case. Proper level should be
in the middle of the sight glass. Check this level when the compressor is disengaged and the vehicle is
parked on level ground. Fluid level should be checked prior to each use.
Electrical System - The Auto Crane compressor’s standard electrical system consists of:
-Hydraulic oil cooler fan assembly and relay.
-12VDC N.O. hydraulic solenoid.
-Switch relay for customer equipment interface during compressor operation.
Most air tools operating pressure range is between 90 and 125 psi.
Operating above the tools’ recommended pressures will decrease the life
of the tool. Higher operating pressure can also over torque nuts and bolts
fatiguing the fastener and mating parts. Strictly adhere to tool operating
pressures and torque standards set forth by the tool manufacturer and the
specifications of the equipment that work is being performed on.
Pressure Switch - The pressure switch is a N.C. electrical switch set to open at 150 PSI and set to close
at 115 PSI. The pressure switch controls the N.O. hydraulic solenoid. If service air pressure is under 150
PSI, the pressure switch will remain in its normally closed state, keeping the N.O. hydraulic solenoid closed
and the compressor producing air. If the service valve is closed or the tool using the air is off, service line
pressure will rise to 150 PSI. This will cause the pressure switch to open and deactivate the hydraulic
solenoid. The compressor will stop making air. If the tool is turned on or the service valve is opened, the
service line pressure will drop. When the pressure falls to 115 PSI, the pressure switch will close, energizing the N.O. hydraulic solenoid forcing flow to the motor and the compressor will start producing air to
meet the demand.
Never adjust the pressure switch to a setting of greater than 150 PSI. Operating the compressor at greater than 150 PSI may result in personal injury and
property damage.

Installation & Operation
This air compressor should be installed only by those who have been trained and delegated to do so and
who have read and understand the manual. Failure to follow the instructions, procedures, and safety
precautions in this manual may result in accidents and injuries.
Install, use, and operate this air compressor only in full compliance with all pertinent O.S.H.A., Federal,
State, and Local codes or requirements in addition to Auto Crane and any company’s regulations.
Do not modify this compressor except with written factory approval.
ALL TRUCKS SHOULD BE ROAD TESTED PRIOR TO STARTING
INSTALLATION TO ISOLATE ANY PREVIOUS TRUCK PROBLEMS.
1. Mounting the Compressor
When mounting the compressor care should be taken to ensure that its location does not impede the
operation of other components on the vehicle. For example, if your vehicle is equipped with a crane,
you must make sure the compressor will not interfere with the swing of the crane. In addition, the
compressor should be installed in an area that permits cool ambient air to enter the air filter and the
hot air to exhaust without recirculating into the air filter. 10” of exhaust clearance is needed. The
compressor air filter is mounted on the frame. Cool ambient air is drawn in from under the frame. One last
consideration in the mounting should be the routing of hoses and electrical wires. The frame mounting holes
are shown below and the unit should be secured to the vehicle with 3/8 inch grade 8 bolts and washers.
Hardware supplied with unit, may not work in all applications. The compressor weighs 180 lbs. Ensure
that you have a sub structure to support at least that weight. Be sure to follow all National Vehicle Safety
Standards.

Installation & Operation
2. Installing the Wiring
This unit is shipped from the factory with all necessary internal wiring installed. The only remaining
wiring necessary is the wiring needed to interface your vehicle/power source with the Auto Crane compressor. The unit is shipped with a 4 pin connector, they need to be connected as follows:
1. Pin “A” and Pin “D” are to be connected directly to battery positive (Pin “A”) and battery
negative (Pin “D”).
2. Compressor Only: for normal compressor operation, supply 12VDC inputs to Pin “B”. This
will activate the system and pressure the tank to 150 PSI. The system will then unload until the
tank has dropped to 115 PSI, at which point it will automatically activate. The 12VDC output
signal from Pin “C” will be present only when the system is compressing.
3. Connecting the Hydraulic Hoses
The hydraulic hoses to the compressor should be connected directly to the hydraulic fittings. The fittings are
3/4” JIC. The pressure “P” input line should be made from a good quality high pressure hydraulic hose 1/2”
or 3/4” I.D. rated to handle the hydraulic systems on the vehicle. The return line to tank “T” can be made
from a medium pressure (min. 1000 PSI) hydraulic hose 3/4” I.D. Care should be taken to see that the
hoses are not installed with kinks or bends that inhibit flow of the hydraulic oil. Lack of flow could result in
damage to the motor and compressor. Lastly check to make sure hoses are not in contact with sharp
objects or edges that may fray, chafe or cut them over time. Secure all hoses with tie down straps or
clamps.
4. Connecting the Air Hose
The air discharge hose should be connected directly to the “AIR” port. The fitting is a 1/2” female NPT. The
air line should be made from a good quality (min. 200 PSI) hydraulic hose 1/2” or 3/4” I.D. Care should be
taken to see that the hose is not installed with kinks. When adding an air hose, ensure OSHA Regulation
1910.169 is followed.

Maintenance
Lubrication Recommendations
It is important that the compressor oil be of a recommended
type and that this oil as well as the air filter element be inspected and replaced as started in this manual.
The following are general characteristics for a piston lubricant. Due to the impossibility of establishing limits
on all physical and chemical properties of lubricants which can affect their performance in the compressor
over a broad range of environmental influences, the responsibility for recommending and consistently
furnishing a suitable heavy duty lubricant must rest with the individual supplier if they choose not to use the
recommended Auto Crane Piston lubricant. The lubricant supplier’s recommendation must, therefore, be
based upon not only the following general characteristics, but also upon his own knowledge of the suitability
of the recommended lubricant in piston air compressors operating in the particular environment involved.

Maintenance
Due to environmental factors, the useful life of all “extended life”
lubricants may be shorter than quoted by the lubricant supplier. Auto
Crane encourages the user to closely monitor the lubricant condition
and to participate in an oil analysis program with the supplier.
No lubricant, however good and/or expensive, can replace proper
maintenance and attention. Select and use it wisely.
Compressor Oil Fill, Level, and Drain
Before adding or changing compressor oil, make sure that the compressor is completely relieved of
pressure. Oil is added at the fill cap on the side of the compressor body. A drain line is located opposite
the service door. The proper oil level is in the middle of the oil sightglass, when the unit is shut down and
has had time to settle. The truck must be level when checking the oil. DO NOT OVERFILL. The oil
capacity is given in “Compressor Specifications”.
Do not attempt to drain condensate, remove the oil level fill cap, or
break any connection in the air or oil system without shutting off
the compressor and relieve the system of all stored air pressure.
Air Intake Filter (P/N 755501213)
The air intake filter is a heavy-duty dry type high efficiency filter designed to protect the compressor
from dust and foreign objects.
Frequency of maintenance of the filter depends on dust conditions at the operating site. The filter
element must be serviced when clogged. A clogged air filter element will reduce compressor performance
and cause premature wear of components.

Maintenance
HYDRAULIC OIL COOLER
The interior of the oil cooler should be cleaned when the pressure drop across it at full flow exceeds 25
PSI.
1. Remove cooler.
2. Circulate a suitable solvent to dissolve and remove varnish and sludge.
3. Flush generously with hydraulic oil.
4. Once the cooler is reinstalled, fill the hydraulic system with the proper fluid to their appropriate levels.

LIMITED WARRANTY
2 YEAR PARTS AND LABOR
Auto Crane will warranty to the consumer for a period of (2) years parts and labor from the date
of purchase. Each new Auto Crane unit they sell will be free under normal use and service from
defects in material and workmanship. Date of purchase will be honored as the date indicated
on the Bill of Sale, which must accompany the Warranty Registration and be on file with Auto
Crane. Absent a valid Warranty Registration and appropriate documentation, the original date
of manufacture, as indicated by the serial number on the product, will be used to determine the
effective date of the 2 year warranty.
The obligation of Auto Crane under this warranty is limited to the replacement or repair of parts
that appear to the manufacturer after review and/or inspection to be defective and paid flat rate
labor for replacing defective parts. This warranty does not obligate Auto Crane to bear the
travel time charges in connection with the replacement or repair of defective parts.
Responsibility for customer’s claims arising from misapplication, abuse, misuse or alteration of
equipment or parts lies with the distributor or user and no warranty obligation is assumed in
these circumstances by Auto Crane.
Auto Crane will in no event be liable for any consequential damages or contingent liabilities
arising out of the failure of any Auto Crane Product or parts to operate properly.
Auto Crane makes no warranty in respect to component accessories, it being subject to the
warranties of their respective manufacturers.
If field service, at the request of the distributor, is rendered and fault is found not to be with
Auto Crane’s product, the distributor shall pay the time and expense of the field representative.
Claims for service labor or other expenses that have incurred by the buyer without approval or
authorization or Auto Crane will not be accepted.
When applying for warranty, claims may be handled by contacting your nearest authorized
Auto Crane Distributor. All claims are to be filed in writing on an Auto Crane Warranty
Claim Form.
AUTO CRANE COMPANY IS UNDER NO OLIGATION TO EXTEND THIS WARRANTY
TO ANY CUSTOMER FOR WHICH AN AUTO CRANE DELIVERY REPORT FORM HAS
NOT BEEN COMPLETED AND ON FILE WITH AUTO CRANE COMPANY
