5) No lubricant should be used on the weight guide shaft.
6) Check that raise/lower bar cable has no bends or broken strands and check that it is in
place on both guide pulleys. Check that the length of cable is properly adjusted and that
cable holding clamps are tight. Check that the two cable tightening springs are not broken.
7) Check that all parts of the movable deflector holders are tight, especially the bottom
measuring tips.
16.3 Electrical/Electronic Parts:
1) Battery terminal clamps must be kept clean and coated to prevent corrosion.
If relevant, check acid level of the trailer buffer battery(-ies) and refill with distilled
water.
2) Check motor brushes for excessive wear at least once a year. Exchange of brushes
should only be performed by qualified personnel (e.g. by Dynatest).
3) Check all four proximity sensors to ensure that they are securely fastened.
4) Check (and exchange if necessary) the two protective rubber boots (caps) of the two
pressure switches P1 and P2. Make sure that the parts of the switches inside the boots
are coated to prevent moisture from penetrating into the switch contact elements.
Preferably fill the boot completely with silicone grease like e.g. Dow Corning DC-4
grease.
5) The heavy trailer fuse box should be periodically checked for possible corrosion. All
metal parts inside the fuse box should be sprayed regularly with e.g. WD40 to prevent
corrosion.
16.4 Hydraulic System
1) Check hydraulic oil level: When the FWD/HWD loading unit is in its transport position
(i.e. when the plate (subunit) has been raised completely) and when parked on a level
surface, then the hyd. oil level should be within the upper half of the level indicator on the
hyd. oil reservoir. The level indicator should NOT be filled completely!
Refill with hydraulic oil (Exxon (Esso) Univis N46 or Shell Tellus T37) if necessary. If
hyd. oil level has been very low, then bleeding may be necessary, refer to Chapter 11.3
FWD/HWD Hydraulics, and the paragraph “Bleeding the Hydraulics”.
2) The hydraulic oil should be exchanged every year (at least). If the equipment is not used
for a longer period (e.g. several months during the wintertime), then preferably perform the
oil exchange at the beginning of this period. After hyd. oil exchange, the hyd. system
should be operated so much that remaining old oil in all cylinders, pipes, etc., will be
exchanged with the new oil, and then the system should be bled, refer to Chapter 11.3
FWD/HWD Hydraulics, and the paragraph, “Bleeding the Hydraulics”
3) Oil filter should be changed every year.
