1. GENERAL INFORMATION Congratulations on your choice of a Powerfist Compressor. This equipment has been designed and manufactured to meet the light industrial and consumer needs of air compressors. Safe, efficient and trouble free operation of your Compressor requires that you and anyone else who will be operating and maintaining the machine, read and understand all of the safety, operation maintenance and troubleshooting information contained within this Operator’s Manual.

IMPORTANT The compressor tank is an ASME certified pressure vessel. The CRN and manufacturer’s information is stamped on the tank nameplate. A certification document with the corresponding serial number is provided with this manual for every compressor tank. Provincial jurisdictions require compressors to be registered with Departments of Labour upon installation.

2. SAFETY GUIDELINES DEFINITIONS Safety symbols identify important safety messages that alert to the possibility of personal injury or death. Review them carefully before operating the unit and before performing maintenance or repairs. Check the rules and regulations at your location and identify possible hazards. The appropriate signal word for each message has been selected using the following guidelines: - Danger indicates an immediate and specific hazard, which will result in severe personal injury or death if the proper precautions are not taken.
2. SAFETY GUIDELINES (cont’d) RISK OF BURNS High temperatures are generated by the operation of the compressor. Contact with hot surfaces, such as the pump or discharge hose could result in a serious burn. Allow them to cool off before handling or servicing. Keep children away from the compressor at all times.
3. OPERATION 3.1 HOW THE COMPRESSOR WORKS 3.1.1 COMPONENTS The basic components of the air compressor are the electric motor, pump, tank and pressure switch. The motor (item A) powers the pump. The motor drives a pulley and belt, which transfers power from the motor to the pump pistons via a flywheel and a crankshaft.
3.1.2 CONTROLS 1. Check Valve Check valves (item G in Figure 1, page 5) are designed to prevent backflow of air pressure in the compressed air system (i.e. air flows freely in one direction only). 2. Pressure Relief Valves The pressure relief valve (item E in Figure 1, page 5) aids in preventing system failures by relieving pressure when compressed air reaches a determined level.
3.1.4 DISCHARGE SYSTEM 1. Discharge Pipe The discharge piping should be of the same diameter as the compressor discharge connection, or sized so that the pressure drop at any point in the system does not exceed 10% of the air receiver pressure.
3.2 ASSEMBLY 1. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged in transit complete a damage claim. 2. Check the compressor’s item number to confirm you have received the model ordered. 3. Ensure that adequate lifting equipment is available for moving the compressor. Follow good shop practices and safety procedures.
3.4 BREAK-IN & START-UP This instruction manual, as well as any instructions supplied by the manufacturers of supporting equipment, should be read and understood prior to starting the compressor. With the pre-operation checklist completed and satisfied proceed to start the compressor. 1.
4. MAINTENANCE 4.1 MAINTENANCE SAFETY 1. Turn off motor and relieve pressure before servicing 2. Open all manual drain valves within the area to be serviced. 3. Isolate the compressor from the compressed air supply by closing a manual shutoff valve upstream and downstream from the compressor.
4.3 PUMP LUBRICANT 1. Oil Level Always operate the unit in a level position. Prior to start-up, check the sight glass to ensure the oil in the pump is at the required level. If the oil level is too low, remove the oil fill plug and add oil until the level is at the center of the sight glass.

4.4 PULLEY ALIGNMENT & BELT TENSION (cont’d) 1. Belt Tension (cont’d) 1/2” Deflection 10 Lbs Force Figure 3: Belt Tension a) Remove the belt guard. b) Loosen the motor mounting bolts. c) Shift the motor to the point where the correct deflection exists. d) Retighten the motor mounting bolts.
4.5 BOLT TORQUE SPECIFICATIONS The table shown below gives the correct torque values for various bolts and cap screws. Tighten all bolts to the torque values specified unless otherwise noted. Periodically check the torque values of all fasteners using the table as a guide. Replace hardware with the same strength materials. Bolt SAE Grade 2 SAE Grade 5...
5. TROUBLESHOOTING PROBLEM CAUSE SOLUTION Excessive motor current draw. Low voltage/motor overload. Check that power supply is adequate and that compressor is on a dedicated circuit. Compressor Stalls. Low voltage to motor. Furnish adequate power. Seized pump. Contact authorized service center. Low discharge pressure.
Page 18
PROBLEM CAUSE SOLUTION Compressor won’t start in cold Too much back pressure in tank. Open drain cock when starting motor. temperature. No power. Check all power sources and circuit. Compressor too cold. Move compressor to a warmer location. Using wrong grade oil. Use ISO 1001 30W compressor oil in temperatures above 30F (-1C) and 10W oil below 30F (-1C).
