FAQ about this machine
All our vertical balers are equipped with the adjustable bale height function, allowing the users to have the flexibility to adjust bale height according to their preference and requirements.
There are 2 types of devices to control bale height:
Type 1 – by Limit Switch
Type 2 – by Trigger Ring
Therefore, please refer to the appropriate device of your baler, and make the necessary adjustment as follow:
Type 1 – Limit Switch
• Move limit switch as per picture below within the adjustable range to adjust bale height as per your preference.
Type 2 – Trigger Ring
• Move trigger ring as per picture below within the adjustable range to adjust bale height as per your preference.
Increasing or decreasing the compressing pressure will directly affect the density of your bale. Please follow the steps below to learn how to adjust compressing pressure on your baler. Remember to refer to the safety working pressure stated on your Operator Instruction Manual to ensure you don’t go above the limit.
Pressure adjustment steps for Mill Size Baler:
1. Start the motor by pressing the “START” button on control panel.
2. Adjust overflow valve (see B) by turning knob clockwise (as per the red arrow) during baling, you will see the pointer of electro-connecting pressure gauge (see A) increase during the process. Turning the knob anti-clockwise, you will see a decrease of pressure.
NOTE:
– Adjust the valve slowly to achieve higher pressure, check the pressure gauge at all time so as to not increase too much at one time.
– The recommended pressure has already been set at our factory before delivery. Therefore, do not make any adjustment to pressure unless it is necessary.
Upon releasing your baling machine from our factory, we will indicate the required amount of hydraulic oil based on your working condition and environment temperature, and reflect it as Best Oil Level for your baler.
You can easily refer to the “Best Oil Level” stickers as a gauge when you are filling up the oil tank and conduct regular checks on oil level (as seen on picture, slight variation above or below the level line is acceptable).
Taking into consideration that actual operation hours and conditions may varies from time to time, regular checks on oil temperature and level is strongly recommended.
Best Oil Level sticker
It is important that clean hydraulic oil is in the pump before running the machine in order to lubricate the bearings and transmission system.
Therefore, do check the pump once you filled up the oil tank, steps as follow:
• Unscrew and remove the oil pipe joint using a wrench.
• Once joint and oil pipe is removed, you can see the oil discharge opening. Fill hydraulic oil through the opening until it is full to the brim. (If there is air in the pump, it will create loud noise when you run it, which might cause damages)
• Reconnect the oil pipe and ensure the joint is tightly fastened.

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

• 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.
