ROUTINE MAINTENANCE & SAFETY CHECKS -- HDD
❒ Care should be taken to identify all potential hazards and comply with applicable safety procedures before
beginning work
❒ Fully lower the chute to the floor before beginning any inspection 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) Before each use inspect for the following:
1) Frayed Wires
2) Oil Leaks
3) Pinched or chafed hoses
4) Damaged or loose barrel height adjustment clamps or pipes
5) Damaged or structural deformation to the structural members, the cylinder brackets, etc.
6) Unusual noise or binding, or evidence thereof
7) Proper functioning of all limit switches
(B) In addition to the above, inspect monthly for:
1) The oil level. Oil should be 1" to 1-1/2" below the reservoir's fill hole wit the chute fully tilted.
2) Worn or damaged hydraulic hoses and electrical wires.
3) Proper operation of the barrel hold-down clamps.
4) Pivot point wear at the hinge pins and cylinder ends.
5) Intact pin and clevis retaining rings and / or fasteners.
6) Frame anchor bolts' tightness, and for cracks in the concrete around them. (Stationary units only)
7) Looseness, wear, or damage to the casters' bearings, mounting hardware, or surface material. (Portable units only)
8) Proper water level in the battery. (DC units only)
9) Unusual noises.
10) Information 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 and 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 Dexron transmission fluid.
