The Test Bench MS300 for diagnostics and repair of brake calipers is intended for long lasting
operation under twenty-four-hour schedule. However, it is essential to inspect the equipment
and observe preventive measures described below with recommended intervals for trouble-free
enduring operation. It is recommended to clean the system from metal chip and other
contamination with a soft brush or cloth on nishing the daily operating shift.
Control the electric motor operation while using the test bench. Unusual sounds, excessive
heating, vibration signalize of a failure.
The recommended period for changing the hydraulic uid (DOT4) and the system lter element
(CR091C10R) is one year of operation. Besides, the brake uid condition and the necessity of its
change is assessed visually, according to its view. It should be transparent, homogeneous,
without sediment. The valve 15 (Fig. 1). is intended for drainage of the power uid. Filling and
relling of the test bench hydraulic system is carried out through the test bench drainage block.
The power uid volume in the hydraulic system is measured with the level sensor 14 (Fig. 1).
The hydraulic system power pressure adjustment is carried out with the help of the adjustment
valve (hexagon) (Fig. 9).
