tors inside the hydraulic components cabinet behind the
operators cab. This warning reminds the servicing tech-
nicians to be sure to close the accumulator drain valves
after they have been opened to bleed brake pressure. It
further warns not to over-tighten the drain valves to pre-
vent damage to the valve seat(s).
