PREVENTATIVE MAINTENANCE
1.
Always store the lift table in a well protected area where it will not be exposed to inclement weather,
corrosive vapers, abrasive dust, or any other harmful elements. The lift table must be free of water,
snow, sand, and debris before using.
2.
Leave hydraulic hose in the carton until needed.
3.
Lubricate moving parts regularly with a general purpose grease. Inspect all lift arms, saddle base, and
cylinder assemblies.
4.
Use a mild soap solution to wash external surfaces of the lift table but avoid any moving hydraulic
components.
5.
Inspect the lift table before each use. Do not use the lift table if any component is cracked,
broken, bent, or leaks hydraulic fluid. Do not use the lift table if it has loose or missing hardware,
components, or has been modified in any way. Take corrective action prior to using.
6.
Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is
familiar with this equipment.
7.
For best results change hydraulic fluid once per year.
