Dhollandia DH-VZ Quick Guide

Performing a basic maintenance check on the Dhollandia DH-VZ involves inspecting the hydraulic fluid levels, checking for leaks, ensuring all bolts and connections are secure, and lubricating moving parts as per the manufacturer's guidelines.
Slow or sluggish operation of the Dhollandia DH-VZ may be caused by low hydraulic fluid levels, contaminated fluid, or issues with the hydraulic pump. Ensure regular maintenance checks and replace fluids as needed.
If the lift won't ascend or descend, check the power supply, inspect the control switches, and ensure the hydraulic fluid is at the correct level. Also, examine the safety mechanisms for any faults.
Before operating the DH-VZ, ensure that the platform is free of obstructions, the safety rails are in place, and all emergency stop functions are operational. Check the load weight against the lift's capacity.
Hydraulic fluid in the DH-VZ should be replaced every 12 months or as specified in the maintenance manual, depending on usage intensity and environmental conditions.
If the platform is uneven, inspect the hydraulic cylinders for leaks or damage, check for blockages in the fluid lines, and ensure the lift is on a level surface. Adjustments may be necessary to correct alignment.
To reset the DH-VZ after a safety shutdown, identify and resolve the cause of the shutdown first. Then, reset the control system according to the manual, typically by cycling the main power switch off and on.
Common signs of wear and tear include hydraulic fluid leaks, unusual noises during operation, slower lift speeds, and visible damage or corrosion on structural components. Regular inspections can help identify these issues early.
When not in use, store the DH-VZ in a dry, covered area to protect it from the elements. Ensure the platform is fully retracted and the power supply is disconnected to prevent unauthorized use.
Basic maintenance tasks can be performed following the user manual, but for complex repairs, it's advisable to consult a certified technician to ensure safety and compliance with warranty conditions.
