TANK PRESSURE GAUGE: This gauge will display how much pressure is being sent to the control box. Each compressor will be different at what psi they shutoff at, small Yetter electric compressor will shut off at 125psi, larger Yetter electric & Yetter hydraulic will shut off at 145psi. -
Page 15: Operation Precautions
OPERATION PRECAUTIONS To ensure the hydraulic compressor motor doesn’t exceed recommended operating RPM level, the hydraulic oil flow control valve has been preset. In some instances, the compressor may run below optimum rpm, or will not reach 145psi of tank pressure read at the gauge on the compressor tank causing the VDM to think the compressor is running continuously. - Page 16 The compressor is shipped empty of pump lubrication & needs oil added before operation. Provided is a 1 Liter bottle of grade 111 full synthetic. Add oil until oil level is seen half way up on sight glass & then recheck oil level on dipstick. Yetter part # for purchasing new bottle is 2940-550.
