6.4 MAINTENANCE
The hydraulic oil quality may deteriorate with the bar feeder running continuously. The cutting
chips and sludge on bottom of the oil tank will be pumped into the hydraulic system thus causing
eventual damage to the hydraulic pump. Dirty bar stock will accelerate oil contamination.
Therefore depending on the cleanness of the bars it is recommended to drain and clean the oil
tank at least once every 6 to 8 months.
Please follow the procedures below:
1. Power OFF the bar feeder system. Verify that most of the oil returned to oil tank.
2. Remove the remnant tray.
3. Place a container with sufficient capacity (minimum: 7.4 gallons [28 liters]) underneath the
drain plug..
4. Remove the drain plug and drain the oil.
5. When the oil tank is empty, clean the sludge inside the tank and bar feeder.
6. Clean the drain plug. Apply the seal on the plug and screw the drain plug back in.
7. Refill the tank with new oil and according to chapter 6.3.4 until the level indicates oil level at
H. Confirm there is no leaks from the drain plug.
8. Install the remnant tray back.
