REPAIR AND MAINTENANCE
Daily maintenance
1. Wipe the machine frequently to keep it clean. Always cut off the power before wiping to ensure
safety.
2. Sweep the working environment of the machine out well frequently, as too much dust in the
working
environment will accelerate the wear of parts and shorten their service lives.
3. Carefully inspect that all safety mechanisms of the machine works flexibly and reliably before
work. In case of any abnormality, adjust, repair or replace the relevant parts immediately.
4. Inspect that the lift pit is dry and clean.
5. Inspect that the air pressure regulating valve is free from air leakage and the lubricating oil is
sufficient.
Monthly maintenance
1. Inspect if the anchor screws are loose, and tighten them if any.
2. Inspect all hydraulic lines for wear and oil leakage; immediately replace the seal as per the
original specifications in case of leakage caused by the wear of seal.
3. Inspect that the slideway of sliding block is well lubricated with the high-quality #2 lithium base
grease.
4. Apply #2 lithium base grease to each lubrication point every month.
Maintenance every 6 months
1. Inspect all moving parts for possible wear, interference and damage.
2. Inspect the lubrication of all rollers. Apply an appropriate amount of lubricating oil to the wheel
shaft if dragging of pulley occurs during lifting.
3. After the first 6 months, clean the hydraulic system with diesel oil and change the hydraulic oil.
Use N32 hydraulic oil in winter and N46 hydraulic oil in summer ever since.
Maintenance every 3 years or after operation for 5,000 times
1. Replace the compound bush at each articulation point.
2. Replace the sealing ring at each oil pipe joint.
3. Replace the sliding block.
