o
Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures
before beginning work.
o
Warning: The load must be removed, and the platform either positively and adequately supported or fully tilted,
before any work is performed on the tilter.
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) Before each 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 all limit switches.
(B) Inspect monthly for:
1.) The oil level. Oil should be within 1” of the reservoir’s fill hole with the cylinder retracted.
See below for the hydraulic oil specification.
2.) Worn or damaged hydraulic hoses and electrical wires.
3.) Hydraulic fluid leaks in any part of the hydraulic circuit.
4.) Pivot point wear.
5.) Rollers’ looseness and wear. (EHTT-L only.)
6.) Integrity of the retaining hardware on all rollers and on all pivot point pins.
7.) The integrity of the frame anchor bolts, and for cracks in the concrete around them.
(Non-portable units only.)
8.) Damage or evidence of fatiguing to the fork tubes. (Portable units only.)
9.) Evidence of fatigue (deformation of the structural parts, cracked welds, wrinkled paint). Check the entire
machine, especially diligently at points that can receive shock-loading such as at hinge pivot areas and cylinder
brackets.
10.) Unusual noises or movement during operation.
11.) All the information, safety, and warning labels being in place and in good condition.
12.) The need to clean off dirt and debris.
♦ Grease the cylinder pins monthly with bearing grease.
(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.
