MAINTENANCE
Make sure that Keep oil clean. Check the oil level in the reservoir before operate and replenish reservoir if oil
does not reach 2/3 of the capacity.
DO NOT use brake fluid or jack oils in the hydraulic system. Replace the oil with anti-wear
hydraulic oil having a viscosity of 150 SUS at 100°F (ISO 32 @ 40°C), or non-synthetic transmission fluid.
INSPECTIONS
To preserve the usefulness of the cart for the greatest period of time, the cart should be regularly
inspected and maintained.
(A) Daily inspections:
1.) Oil leaks.
2.) Pinched or chafed hoses.
3.) Damage to the casters.
4.) Damage or deformation of the structural members, cylinder brackets, etc.
5.) Unusual noise or binding, or evidence of grinding/binding.
(B) Monthly inspections:
1.) The oil level. Oil should be 1” to 1½” below the fill hole of the reservoir with the platform in the
fully lowered position. Add oil if necessary. [See “Yearly inspection” below for information about
the necessary properties of the hydraulic oil.]
2.) Worn or damaged hydraulic hoses.
3.) Significant wear at pivot point(s).
4.) Looseness and significant wear of roller(s).
5.) Integrity of hardware retaining each roller and fasteners at all pivot points.
6.) Loose, significantly worn or damaged caster bearings or mounting hardware.
7.) Accumulation of dirt or other material on the cart.
8.) Proper, normal function of all hand and/or foot-operated mechanisms.
9.) Unusual noises or movement during operation.
10.) All the information/safety/warning labels being in place and in good condition.
(C) Yearly inspection
Change the oil if it darkens, becomes gritty, or appears milky, which indicates the presence of water.
Replace the oil with anti-wear hydraulic oil having a viscosity grade of 150 SUS at 100°F, (ISO 32 at
40°C). Examples of acceptable replacement oils include AW 32 and HO 150 hydraulic oils and
non-synthetic transmission fluid.
