INTRODUCTION The Yetter 2940-106 Hydraulic Air Compressor converts hydraulic power into compressed air. Yetter Hydraulic Compressor units are durably constructed and designed for easy integration to operate the Yetter 2940 Air Adjust System. IF USING THIS COMPRESSOR TO SUPPLY AIR TO OPERATE ANOTHER SYSTEM, INSTALL A REGULATOR PRIOR TO AIR ENTERING THAT SYSTEM WITH PROPER REGULATED AIR SETTINGS RECOMMENDED BY OEM PRODUCT.
BOLT TORQUE Mounting bolts and hardware Before operating the Yetter Hydraulic Compressor for the first time, check to be sure that all hardware is tight. Check all hardware again after approximately 50 hours of operation and at the beginning of each planting season. All hardware used on the Yetter Hydraulic Compressor is Grade 5 unless otherwise noted. Grade 5 cap screws are marked with three radial lines on the head.

Hydraulic Fittings Identification Chart -Due to common threads, mismatching can happen and could result in leaks and pressure loss -Be sure to verify which style and use dash sizes when ordering replacement parts -NPTF is easily recognizable and looks like regular pipe threads. It is not recommended for hydraulic systems but does exist on some agriculture equipment -SAE ORB is recommended by the NFPA for optimal leakage control in medium and high pressure hydraulic systems.
Quick Start Guide Step 1: Preparing Hydraulic Compressor for Installation After removing the hydraulic compressor from the shipping crate, remove cap from elbow fitting and install air filter assembly securely. Next, remove screen on housing on the side of the sight glass(same side as pressure gauge) and fill compressor pump with oil until oil is in middle of sight glass. See page 16 for further information on filter installment and oil filling.

MAINTENANCE CLEANING OR REPLACING THE 2940-106 AIR FILTER Filter cleanliness is critical to maintain the performance and service life of the compressor. Recommendations for cleaning are daily and replace every 200 hours OR at beginning of every planting season.
MAINTENANCE WARNING: Keep extremities out of the compressor housing when compressor is running, has potential to run, or recently shut off as there are rotating and high temperature parts that my cause injury. Always turn tractor off and disconnect power before performing any maintenance. LUBRICATION: The compressor is shipped empty of pump lubrication and needs oil added before operation. Provided is a 1 Liter bottle of grade 111 synthetic. Add oil until oil level is seen half way up on the sight glass.
