4. Inspecting the Machine
• Ensure the baler is placed on level ground.
• Check if the power switch and wires for loose connection or damages.
• Check the safety devices are complete and effective.
• Check if the hydraulic hose, joints are firmly fastened.
• Check for loose wires in cabinet, and/or machinery screws, tighten if necessary

5. Installation and Operation

5.1 Connect the power supply
Make sure the voltage range meets the machine requirements.

Wires of electrical box => There are three live lines and one earth line.
The colors of wires comply with Chinese standard:
• Phase A – yellow
• Phase B – green
• Phase C – red
• Earth – yellow/green

Note: Connect the earth wire to the wiring terminal


5.2 Fill Hydraulic Oil
Fill hydraulic oil through “Oil filler” until reaches “Best Oil Level”.

The requirements of the suitable hydraulic oil in different ambient temperature:
NOTE: If your machine is using Plunger Pump, it is important that clean hydraulic oil is in the pump before running the machine in order to lubricate the bearings and transmission system.  Refer to “How to refill oil to Plunger Pump” if you need further information.

5.3 Turn on the main switch and observe for abnormality

5.4 Start motor and then immediately stop
Observe the rotation from the motor fan. If the motor rotates in wrong direction (not as per the red arrow), inter-change any two phases of the three-phase power supply wires.
Start the motor and hydraulic pump to run it for about 1-3 min, then observe hydraulic pump, check if there is any abnormality like unusual noise or smell. If yes, switch off the machine immediately. Investigate the cause and eliminate abnormality.  Proceed to restart motor once problem is rectified.

5.5 Check for Oil Leakage
If leakage is detected, rectify the cause or contact SINOBALER immediately.

5.6 Check Oil Temperature
If the oil temperature is below 10 ° C, it is recommended to run the motor for a few minutes (do not load the machine with material or operate the platen at this point).

Begin to operate the machine once the oil temperature is above 10 ° C.

5.7 Test Running (without Material)
Control Panel

•  Back (a): Move ram upwards
•  Power Indicator Light (b): Light will be on when power is on
•  Start (c): Start the motor
•  Press (d): Move ram downwards
•  Switch (e): Select “Auto” mode and “Manual” mode (see picture below)
•  Stop (f): Stops the machine once pressed. To resume operation, just rotate the button clockwise as per the direction of arrow to reset.


** Go to Control Panel and switch to “Manual” mode **

•  Close the chamber door and feeding door, turn on the main switch and start the motor.
•  Press “PRESS” button and hold, observe if the platen moves downwards steadily, no jam or abnormal sound.
•  Press “BACK” button and hold, observe if the platen moves upwards steadily back to home position.
•  Press “STOP” (red) button and check whether machine shuts down / motor stops (after that, turn it clockwise to reset the stop button).

Suggest to test run the above steps 2-4 times under “Manual” mode.

** Go to Control Panel and switch to “Auto” mode **

•  Close the chamber door and feeding door, turn on the main switch and start the motor.
•  Press “PRESS” button (just press once, no need to hold), platen will move downwards automatically.
•  When the ram move downwards and trigger the bale height sensor, it will move upwards automatically.

Suggest to test run the above steps 2-4 times under “Auto” mode.

5.8 Trial Production
•  According to auto mode test running steps, feed material into chamber from feeding door until full and begin baling cycle by pressing the “PRESS” button.  Repeat step again.
•  Platen will stop when achieved the pre-set bale height. Bale height is adjustable by moving the “Bale Height Adjust Block” as per picture below.
•  Once the platen stops and not returning to home position, open the chamber door by turning the decompression wheel, and proceed to strap the bale.
•  Hang the ejector chains on platen at the back of machine.
•  Press “BACK” to move the platen upwards and bale will be ejected out in this process. DO NOT stand in front of baler during ejecting.
•  Repeat the next baling cycle.  The bale ejector chains will release automatically when the platen press down for the next compressing cycle.

•  During test running, inspect the machine for any abnormality (i.e. abnormal noise, leakage, etc.).  Check the machine again after test run. If all normal, you can start mass production.
•  DO NOT remove or override any safety guards or switches to operate the machine.
•  Do not start and stop motor too frequently as it may burn the motor.

6. End of Operations
•  Move platen upwards to home position
•  Reset the ejector chains
•  Clear away any residual material in chamber and close chamber door
•  Close feeding door
•  Turn off motor by pressing the Stop button
•  Switch off main power
•  Clean the machine and its surrounding
•  Arrange tools neatly, and clean-up site / work area
