ROUTINE MAINTENANCE & SAFETY CHECKS - HT, LDLT
Care should be taken to identify all potential hazards and comply with applicable safety procedures
before beginning work.
Only qualified individuals trained to understand mechanical devices and their associated electrical and
hydraulic circuits should attempt troubleshooting and repair of this equipment.
(A) Before each use inspect the following, where applicable:
1.) Frayed wires.
2.) Oil leaks.
3.) Pinched or chafed hoses.
4.) Damage or structural deformation to the structural members, the
cylinder, the foot pump, etc.
5.) Unusual noise or binding or evidence thereof.
6.) Proper functioning of all limit switches.
(B) Inspect monthly for, where applicable:
1.) The oil level. Oil should be 1" to 1 1/2" below the cylinder's
or the reservoir's fill hole with the lift in the fully lowered position.
2.) Oil leaks.
3.) Worn or damaged hydraulic hoses and electrical wires, if applicable.
4.) Integrity of the retaining rings and pins at all pivot points.
5.) Looseness, wear, or damage to the casters' bearings, mounting
hardware, or surface material.
6.) Proper water level in the battery. (DC units only.)
7.) Unusual noises.
8.) Information and warning labels being in place and in good condition.
9.) The need to clean off dirt and debris.
(C) Yearly inspection
The oil should be changed if the oil darkens, becomes gritty, or turns a milky color
(indicating the presence of water). Replace with an anti-wear hydraulic oil with a
viscosity grade of 150 SUS at 100°F, (ISO 32 @ 40°C). Ex: AW 32 or HO 150
hydraulic fluid, or non-synthetic transmission fluid.
