Dhollandia DH-VO K1 Operation Manual

To perform regular maintenance on the Dhollandia DH-VO K1, check hydraulic fluid levels monthly, inspect and lubricate all pivot points, and ensure the electrical connections are clean and secure.
If the liftgate is operating slowly, check the hydraulic fluid level and replenish if necessary. Also, inspect the battery voltage to ensure it is adequate for liftgate operation.
First, check the power supply and ensure the battery is charged. Inspect the control switch and wiring for any faults. If the problem persists, check the hydraulic fluid level and inspect for any leaks.
Unusual noises may indicate a need for lubrication at pivot points or might be caused by loose components. Inspect and tighten any loose parts and apply appropriate lubricants.
The hydraulic fluid should be changed every 12 months or after 1,000 hours of operation, whichever comes first, to ensure optimal performance.
When storing the liftgate for long periods, ensure it is clean and dry. Lower the liftgate to the ground and disconnect the power supply to prevent battery drain.
Ensure all operators are trained properly in the use of the liftgate. Regularly inspect the liftgate for any damage or wear, and always adhere to the weight capacity limits specified by the manufacturer.
Inspect for any obstructions or debris in the folding mechanism. Ensure all pivot points are lubricated and check the alignment of the folding arms.
To reset the control system, turn off the power to the liftgate, wait for 30 seconds, and then turn it back on. If issues persist, consult the user manual for further instructions.
Common signs of hydraulic leaks include visible fluid around hydraulic cylinders or hoses, reduced liftgate performance, and unusual noises during operation.
