To compress air，the piston move up and down in the cylinder，During the down-stroke，air is drawn in through the inlet valve，The discharge valve remains closed，On the up-stroke of the piston，air is compressed。The inlet valve closes and compressed air is forced out through the discharge valve、through the check valve and into air receiver tank。Working air is not available until the compressor has raised the air receiver pressure above that required at the air service connection。The air inlet filter openings must be kept clear of obstructions。Your air compressor can be used for operating paint spray guns、air tools、caulking guns、grease guns、air brushes、sandblaster、or inflating tires and plastic toys、spraying weed killer and insecticides、etc., An air regulator is usually necessary for most of these application。

Each PUMA air compressor outfit is carefully factory tested and inspected before shipment。

Every attempt is made to ensure safe and complete shipment of our products。 It is the responsibility of the receiver of the goods to ensure the products has been shipped in full and arrival in suitable condition to avoid expenses being incurred to correct such problems。With improper handling，damage may result in transit and cause problems in compressor operation。

It is your responsibility to ensure air compressor is installed correctly，as well as maintained and serviced on a regular basis。Information has been included in this booklet outlining the suggested air compressor maintenance schedules and a trouble shooting guide， It is important that you read this information and keep it in a safe place for future reference。

Located the compressor in a clean、dry and well ventilated area。 The compressor should be located 12 ~ 18 inches from a wall or any other obstruction that would interfere with the air flow through the pump flywheel，Place the air compressor on a firm and level surface。 The air compressor is designed with heat dissipation fins that allow for proper cooling。Keep the fins and other parts that collect dust or dirt clean。 A clean compressor runs cooler and provides longer service。 Allow room for easy access to the air compressor for maintenance and service work。

5

5.1-1： For vertical type permanent installation，the compressor should be bolted to the floor through holes provided in the compressor feet。 Shims must be used to level the compressor before bolting it to the floor， Sever vibration will result when the compressor is bolted down tightly and the feet are not level， This can lead to welds cracking or fatigue of the air receiver。

It is your responsibility to ensure that the air compressor is electrically connected in a safe and correct manner。 Any electrical work should be carried out by a competent electrician and installed in a way which meets all applicable codes and regulations。A magnetic start must be an integral parts of the air compressor except on contractor and professional series units。A magnetic starter may be supplied with your unit from the factory。

Failure to connect the air compressor correctly to your buildings electrical services may result in serious personal injury or damage to the equipment。

Please note that under normal conditions，the air compressor will operate intermittently。Should it be necessary to service that air compressor ensure the power source has been shut down。

This must be down to prevent personal injury or damage to the unit。

If the supply cord is damaged it must be replaced by the manufacturer or its service agent or a suitable qualified person in order to avoid a hazard.

Wiring must be down in a manner that full voltage nameplate ±10% is available at the motor terminals during startup。Use of an incorrect electrical motor for your particular building service will result in premature motor failure and is not covered by PUMA compressor or motor manufacture’s warranty。

6

The pressure switch located on the compressor unit acts as a pilot device activating the coil on the magnetic starter except on contractor and professional units where the pressure switch would act as a pilot device activating the motor。The pressure switch cut in/cut out has been preset at the factory，do not tamper with the settings。 Never bypass or remove this switch ，as serious damage to equipment or personal injury could result from too high of an air pressure。Consult your local distributor or service center should the switch not be operating properly。

5-2-3： Do not modify the plug that has been provided，if it does not fit the available outlet，the correct outlet should be installed by a qualified electrician。If these grounding instructions are not completely understand，or if in doubt as to whether the compressor is properly grounded，have the installation checked by a qualified electrician。

The compressor is to be wired in a manner that the rotation of the flywheel causes the air to be blown over the pump。This allows the pump to cool properly。Rotate the unit with an arrow on the belt guard or motor。

Do not add or change oil while the compressor is in operation，use the recommended

SAE10-30W non-detergent oil only。

6-1-1： Remove the oil filler plug。

6-1-2： Slowly pour the proper oil into the pump crankcase。

6-1-3： Always keep oil level between the marks “up” and “low” level on the oil stick or on the red circle on the sight glass。

Change oil after the first 8 hours of compressor operation， then change oil after every 300 working hours or 3 months whichever comes first。

6-2-1： Remove the oil drain plug，allow oil to drain out。

6-2-2： Replace the oil drain plug，the use of a sealing compound or Teflon tape to avoid leakage is recommended。

6-2-3： Refill with the recommended oil to the proper level。

7

Do not attempt to operate the air compressor unit without first checking the oil level in the pump，add oil as required。Serious damage may result from use without oil。

7-1： Check to see that nuts and bolts are all snug，this must be down，as some fasteners may become loose in transit。

7-2： Check to see if the belt is installed properly，with proper tension。

7-3： Check belt tightness so that when pressure is applied at the center，there is 1/2” slack。

7-4： Check that proper type and level oil is correct，see page for proper compressor lubrication。

7-5： Check that compressor is fixed on a strong、stable level base。

7-6： Check that oil breather is clean。

7-7： Check that air filter is clean。

7-8： Do not place any materials on or against the belt guard，or the compressor unit itself。

Placing materials there will limit the cooling of the air compressor and could lead to premature failure。

7-9： Turn the compressor “on” momentarily by positioning the fused disconnected in the

“on” position。

Ensure that the flywheel is turning in the correct direction。On compressors with three phase power，adjust the wiring at the motor terminals if the rotation is incorrect。Refer to the wiring diagram on or in the motor terminal box。

7-10： Open the air receiver outlet ball valve and start the unit。Ensure air is escaping to atmosphere。

Allow the unit to operate for a minimum of twenty minutes in this no load condition to lubricate bearings and piston。

7-11： After running the compressor for twenty minutes，close the ball valve，and allow the unit to reach maximum operating pressure。Ensure that the compressor shuts down at the preset maximum pressure，and the head pressure is released through pressure switch。

7-12： Check the air compressor and piping systems for leakages，and correct as required。

7-13： Shut off of all power to the air compressor before attempting any repair or maintenance，

7-14： Stop the compressor，and check the oil level in the crankcase。Add oil as required。

8

7-15： Your compressor is ready for use。

Before doing any maintenance or adjustments to your air compressor，the following safety precautions should be taken。

8-1-1： Check oil level。

8-1-2： Drain condensation from air receiver tank。

Adjust belt tension if necessary or replace belt if worn。

8-3-3： Check safety valve。

8-3-4： Check pressure switch unloads to ensure compressor head unloads whenever motor shuts down。

8-3-5： Clean and blow off pump fins and motor。

8-3-6： Inspect air system for leaks by applying soapy water to all joints。Tighten joints if leakages are observed。

9-1： Set the “on/off” switch to “off” and unplug the cordially,

9-2： Be sure to drain the water from the air tank。

9-3： Protect the electrical cord and air hose from damage。
