ROUTINE MAINTENANCE & SAFETY CHECKS – EHLTG
•
Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures before
beginning work.
•
Warning: Raise the platform and install the maintenance props before beginning any inspections or work on the unit.
•
Only qualified individuals trained to understand mechanical devices and their associated electrical and hydraulic
circuits should attempt troubleshooting and repair of this equipment
(A) Beforeeach use inspect for the following:
1.) Frayed wires
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 the limit switch and the toe guard switch.
(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 raised position. See
below for oil specification.
2.) Worn or damaged hydraulic hoses and electrical wires.
3.) Pivot point wear.
4.) Rollers’ looseness and wear.
5.) Integrity of the retaining rings on all rollers and on all pivot point pins.
6.) The integrity of the frame anchor bolts, and for cracks in the concrete around them.
7.) Proper functioning of any hand- or foot-operated mechanisms.
8.) Unusual noises or movement during operation.
9.) All the information, safety, and warning labels being in place and in good condition.
10.)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). Re-
place 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.
