Record of Satisfactory Condition – TCD-U [
Refer to Exploded View on either p. 7 or p. 8 .]
Before putting the machine into service, make a record of its appearance and functions. Photograph the modular
power unit, frame, chute, retainers and rails, handles, casters, safety guards, and fasteners (bolts, nuts, etc.). Take
close range photographs of all labels. Cycle the chute all the way up and back down. Record observations about how
the cylinder extends and retracts, how the chute rotates, and all sounds heard. Collate the photographs and written
descriptions into a single. Mark the file appropriately to identify it. This record establishes satisfactory condition. During
future inspections, compare your observations to this record to determine whether the machine is in satisfactory
condition. Do not use the dumper unless it is in satisfactory condition. Purely cosmetic changes, like damaged surface
coating (paint or powdercoat) are not changes from satisfactory condition. However, touchup paint should be applied
as soon as damage occurs.
Inspections – TCD-U series dumpers
Before each use, inspect the listed components:

Modular power unit, pendant controller, wiring: Remove the
cover. Examine wires for frays, cuts, tears, etc. Inspect the oil
reservoir, hoses, and fittings for leaks, kinks, punctures (DC-
powered units) Check battery charge status. Recharge the
battery, if necessary.

Hydraulic system: Check the hoses for pinches, kinks,
punctures, and leaks. Check connections for leaks, etc.

Bin retainers and clamp rails: Examine the retainers for
damage such as bends, cracks, and looseness. Each clamp
should maintain position along the rail (i.e. should not slide).
Rails should be straight and rigidly welded to the chute

Frame: Check the welds and overall condition of the safety
guards, pivot points, cylinder brackets (on the frame and the
chute), handles, and chute. Look for cracks, damaged welds,
severe wear, and corrosion.

Cylinder and limit switches: Cycle the chute through a
complete dumping sequence (fully rotated and back to the
ground). When the chute reaches maximum dumping height,
the power unit should stop running. Lower the chute. The piston
should extend and retract smoothly without binding or jerking.
Listen for unusual sounds that might indicate binding during
operation. Watch for unusual movement. If you observe any
unusual sound or movement, do not use the dumper until it has
been restored to normal operating condition.
At least once per month , inspect the dumper as follows:

Oil level: remove the cover from the modular power unit.
Then, fully raise the chute (to the 45° “dumping position”) and
observe the level of oil in the reservoir. The surface of the oil
should be 1 to 1½ inches below the fill port. If oil is needed, add
oil as specified below in “Oil specifications”.

Casters: confirm that all 4 casters roll smoothly. The front
casters should swivel freely through 360°. The rear casters are
rigid, i.e. do not swivel. Confirm that the rear casters are
secured in their respective receivers.

Fasteners: check each fastener connection (nuts, bolts, pins,
etc.). Tighten loose connections. Replace damaged hardware.

Hydraulic hoses and electrical wires: check each wire and
hose for damage (frays, kinks etc.).

Floor locks: verify that both floor locks operate normally (one
on either side of the frame).

Labels: labels should be easily readable, undamaged, and
be located as shown in the “Labeling diagram” on p. 19.
Oil specifications: Change the hydraulic oil at least once per
year
. Change the oil as soon as it becomes gritty or looks milky
(indicating that water is present). With the chute in the fully
lowered position, drain the oil and replace it with either Dexron
transmission fluid or anti-wear hydraulic oil viscosity grade 150
SUS at 100°F (ISO 32 cSt at 40°C.
