Hydraulic Cylinder – Easy Care Tips:
1. Don’t exceed 1.25x of the cylinder’s rated pressure.
2. Wipe the piston rod regularly – keep it clean and scratch-free.
3. Use the right oil:
32# for normal use
20# if it’s cold
46# if it’s hot
4. Best working temperature: -20°C to 70°C (never go over 70°C).
5. Filter your hydraulic oil after 3 months, then once a year – it keeps the oil clean and your cylinder lasting longer.
