Warning: Care should be taken to identify all potential hazards and comply with applicable safety
procedures before beginning work.
o
Warning: Remove any load, raise the platform, and install maintenance props before beginning any
inspections or work on the unit.
o
Only qualified individuals trained to understand mechanical devices and their associated electrical and
hydraulic circuits should attempt troubleshooting and repair of this equipment
(A) Inspect daily for:
1.) Frayed wires (DC units).
2.) Oil leaks.
3.) Pinched or chafed hoses.
4.) Damage or structural deformation to the structural members, the cylinder brackets, etc.
5.) Unusual noise or binding, or evidence thereof.
6.) Proper functioning of all limit switches, including those on the perimeter pinch point guard (DC units).
(B) Inspect monthly for:
1.) The oil level. Oil should be 1” to 1½” below the reservoir’s fill hole with the lift in the fully lowered
position.
2.) Oil leaks.
3.) Worn or damaged electrical wires (DC units) or hydraulic hoses.
4.) Pivot point wear.
5.) Rollers’ looseness and wear.
6.) Integrity of the retaining hardware on all rollers and on all pivot point pins.
7.) Looseness, wear, or damage to the casters’ bearings, mounting hardware, or surface material.
8.) Proper water level in the battery (DC units only.)
9.) Unusual noises.
10.) All the information, safety, and warning labels being in place and in good condition.
11.) 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 at
40°C). Ex: AW 32 or HO 150 hydraulic oil, or a non-synthetic transmission fluid. You may use a synthetic
transmission fluid if you flush the system with the synthetic fluid before filling the reservoir.
