Technical Support

is proud of its innovative and creative principles and ideas being interpreted by our industrial balers. Our team of baling engineers with skillful technicians adheres to a strict quality control system to build each and every one of our state-of-the-art baler.

Balers from Sinobaler are CE compliance and every baler produced in our facilities passed final in-house testing before it is shipped out to our customers world-wide. We are proud to be a preferred waste recycling equipment supplier and partner to our global customers.


Preventative Maintenance

arrow feature Cleanliness Always keep the machine clean, especially around the operation control system. Remove dust, dirt or any materials on/near the machine. Daily
arrow feature Inspection of Pipeline Damage Inspect pipeline where material enters into baling chamber for damage or obstructions Daily
arrow feature Oil Leak Detection Excessive oil on the cylinder rod is a sign that the seals should be replaced. A thin-film of oil is considered as normal. Improper tightening or adjustment of fittings may cause leaking problem. Finding the root that causes leakage early can avoid serious problems for the operation of hydraulic system. Weekly
arrow feature Lubrication Lubricate the door hinges, latches and gate guides Monthly
arrow feature Replacement of Oil Filter Replace oil filter in hydraulic system Yearly
arrow feature Refilling Hydraulic Oil Change the hydraulic oil for stable operation Yearly

Common Problems Possible Causes Solutions
No Electrical Power Machine is not plugged in;Power “ON” switch is off;or Fuse is burned out Ensure machine’s power cable is connected to power supply in your facility.Turn on the power switch in electrical cabinet.Check for blown fuse in electrical cabinet, and replace with a new one.
Low Pressure Pressure value set for relief valve is too low (i.e. lower than recommended safe working pressure stated on your operator Manual) During last compression cycle with material, turn the adjustment knob of relief valve slowly and monitor pressure gauge closely.  Stop when the pressure reaches the recommended value.  Tighten the fixing nut connected to adjustment knob.If relief valve is not available for adjustment, try cleaning it. Replace a new relief valve if problem persists after cleaning.
Pump cavitation (i.e. noisy operation) Check oil volume in oil tank and pump intake lines.  If the oil level is low, refill some oil till it reaches “Best Oil Level”.  Replace old or damaged pump intake lines, and ensure all clamps and fittings are tight.
Filter is blocked Check if the suction filter is blocked. If yes, please replace with a new filter.
Pump may be damaged Make visual inspection and replace if necessary
Cylinder seals are worn Disassemble the cylinder and replace seals.
Cylinder rod is bent and causes sealing failure Check cylinder rod and replace if it is damaged.
Failure of pipeline sealing Check and change O-shape seal.
Machine does not work Pump may be running in the wrong direction Exchange any two of the motor leads in the control cabinet.
No hydraulic oil Fill in hydraulic oil till it reaches “Best Oil Level”.
The cylinder can move only in one direction Valve core is stuck Insert a small rod to push the valve core or dismantle the valve to clean.
The platen of the baler is not moving Valve coil is burned out Inspect electrical system with multimeter.  If the wires are good, please check the coil in solenoid valve.  But if there is no electrical signal from the circuit, please check the wiring lines.
Limit switch is broken. Check limit switches with multimeter and replace the broken switch.
Unable to achieve maximum bale weight Bale height is set too low Limit switch is adjustable, therefore move it to the highest position to achieve maximum bale size. If still unable to achieve maximum bale weight, refer to pressure gauge as it may be set lower than recommended value.
