MAIN FRAME DOES NOT LOAD IN MANUAL MODE (CONTINUED)

THAAD0708A

WARNING

The THAAD hydraulic system operates up to 3,100 psi (21,374 kPa).

Never

disconnect any hydraulic line or fitting without first dropping system pressure to

zero.

Failure to comply may result in serious injury or death to personnel.

CAUTION

•

Engine speed must be at idle before using LHS cab mode select switch.

Failure to

comply may result in damage to equipment.

•

Fully extending or retracting cylinders will put hydraulic system into relief.

This

should be limited to 10 seconds.

Failure to comply may result in damage to

equipment.

NOTE

During empty load or unload cycle, hydraulic pressure will read

approximately 1,000 psi (6,895 kPa) until cylinders are fully extended or

retracted.

3,100 psi (21,374 kPa) will be reached when cylinders are fully

extended or retracted.

Step 4.

Remove pressure transducer from LHS main manifold assembly (WP 0136) at port

TPMB. Install pressure gage at port TPMB. Start engine (

Turn

PTO switch to ON position (WP 0011). Soldier A checks for 3,100 psi (21,374 kPa) at

port TPMB, while Soldier B attempts to load main frame (WP 0016). Note reading. Turn

PTO switch to OFF position (WP 0011). Shut off engine (

Disconnect pressure gage from port TPMB. Install pressure transducer to port

TPMB (WP 0038).

If 3,100 psi (21, 374 kPa) are not present, replace main frame directional

control valve (WP 0125).
