BRAKE ACCUMULATOR DOES NOT CHARGE, CHARGES FREQUENTLY - continued

TM 10-3930-673-34

WARNING

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.

CAUTION

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.

PRESSURE TEST

(1) Remove cap from diagnostic coupler

on brake control valve.

(2) Perform a pressure test at the

diagnostic coupler.

BRAKE

(a) If hydraulic pressure is between

CONTROL

1600 and 1700 psi (11032 and

signs of damage.

PRESSURE

(b) If hydraulic pressure is not
