IMPORTANT SAFETY INSTRUCTIONS Improper operation or maintenance of this product could result in serious injury and property damage. Read and understand all warnings and operation instructions before using this equipment. WARNING: Risk of explosion or fire What Could Happen It is normal for electrical contacts within the motor and pressure switch to spark.

WARNING: Risk of Bursting Air Tank: The following conditions could lead to a weakening of the tank, and result in a violent tank explosion and could cause property damage or serious injury. What Could Happen Failure to properly drain con- densed water from tank, causing rust and thinning of the steel tank.

WARNING: RISK OF BURNS WHAT CAN HAPPEN Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns. WARNING: RISK FROM MOVING PARTS WHAT CAN HAPPEN Moving parts such as the pulley, flywheel, and belt can cause serious injury if they com into contact with you or your cloth- ing.
RISK OF UNSAFE OPERATION WARNING: WHAT CAN HAPPEN Unsafe operation of your air compressor could lead to serious injury or death to you or others. HAZARD HOW TO PREVENT IT Always place COMPRESSOR on a pro- tective mat when transporting to protect against damage to vehicle from leaks.
* A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same rating as the branch circuit on which the air compressor is operated. If compres- sor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked "D"...
A small amount of oil may be pres- ent in the pump upon receipt of the air compressor. This is due to plant testing and does not mean the pump contains oil. Do not attempt to operate this air compressor without first adding oil to the crankcase.
(not supplied) 4 - 5/8" Washer (not supplied) - Shims (if needed) D25235 INSTALLATION Place the air compressor on on a solid, level surface. Mark the surface using the holes in the air compressor feet as a template.
Use only metal pipe for air distribution lines. The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system. 11-ENG D25235...
• Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. • If piping is over 100 feet long, use the next larger size. • Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze.
"cut-out" pressure. Safety Valve: If the pressure switch does not shut off the air compressor at its "cut-out" pressure setting, the safety valve will protect against high pressure by "popping out" at its factory set pressure (slightly higher than the pressure switch "cut-out"...
This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced. Make sure the On/Auto/Off lever is in the "OFF" position.
IMPORTANT: When using regulator and other accessories refer to the manu- facturer-s instructions. NOTE: Always operate the air compressor in well-ventilated areas free of gaso- line or other combustible vapors. If the compressor is being used to operate a sprayer, DO NOT place compressor near the spray area.
Before performing any maintenance or repair, disconnect power source from the compressor and bleed off all air pressure. To ensure efficient operation and longer life of the air compressor outfit, a rou- tine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working envi- ronment operating on a daily basis.
NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. NOTE: Use a air compressor oil such as SAE-30 (API CG/CD heavy duty motor oil). Under extreme winter con- ditions use SAE-20 weight oil. NOTE: Crankcase oil capacity is approxi- mately 60 fluid ounces (1.8 L).
Never operate the outfit with the belt guard removed. The belt guard should be removed only when the AIR compressor power is disconnected. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.
1/16" to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps: Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. Remove belt guard.
Valve Release all air pressure from air tank. See "To Drain Tank" in the Maintenance section. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank. Using an adjustable wrench loosen outlet tube nut at air tank and pump.
Allow the motor to cool. Depress the red reset button on the motor. Reset Button Before you store the air compressor, make sure you do the following: Review the "Maintenance" sec- tion on the preceding pages and perform scheduled maintenance as necessary.
Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or com- pressd air sources. Personal injury may occur. Prior to attempting any repairs, unplug the air compressor and bleed off all air tank air pressure. PROBLEM Excessive tank...

Decrease amount of air usage. Check the accessory air requirement. If it is higher than the SCFM or pressure supplied by your air compressor, you need a larger compressor. Check and replace if required. Remove and clean, or replace. Tighten fittings.
