Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with effective chip guarding and personal
protective equipment (goggles/shield, gloves, and so forth).
Adhesives, solvents, and sealing compounds can burn easily, can give off harmful vapors, and are harmful to skin and clothing.
To avoid injury or death, keep away from open fire and use in a well-ventilated area. If adhesive, solvent, or sealing compound
gets on skin or clothing, wash immediately with soap and water.
Wipe area clean around all hydraulic connections to be opened during removal. Cap oil lines and plug holes after removing lines.
Contamination of the hydraulic system could resulting premature failure.
(1) Remove cap from diagnostic coupler
on brake control valve.
(2) Perform a pressure test at the
(a) If hydraulic pressure is between
1600 and 1700 psi (11032 and
11722 kPa), inspect pilot valve for
signs of damage.
(b) If hydraulic pressure is not
between 1600 and 1700 psi (11032
and 11722 kPa), go to Step 2 of
