12.4 Air Removal (Bleed-off) Procedure
IMPORTANT: Before raising the scale, ensure shipping bolts are
removed.
During the bleed-off procedure, which removes air from the hydraulic system, some oil
will be lost. Do not allow the hydraulic pump to run dry. Serious damage and
failure of the hydraulic pump can occur.
1. Plumb the valve to a hydraulic power source and hydraulic reservoir. This can be the
hydraulic source on the truck or a portable power pack.
2. With the cylinders down, loosen the top fitting of one of the cylinders. Place a pail
or can under the fitting to catch oil.
3. Raise and lower the scale. Continue raising and lowering until the oil coming out of
the top fitting is clear (not bubbly or creamy).
4. Tighten the top fitting.
5. Repeat steps 2 through 4 for all other cylinders.
6. Repeat steps 2 through 5 for the bottom fittings of all cylinders.
13. Lock Down Bolt Adjustment
The lock down bolt is adjusted at the factory. However, to ensure proper lock down of
the container, check the lock down bolt height adjustment.
The lockdown bolt should be adjusted so that the hydraulic cylinder is extended
minimum 1/8” to maximum 1/4” when locked down – see
Figure 10. As well, the load cell should be loose in the lock down position.
