the two washers (B) and locknuts (A) to secure the hydraulic cylinder (I) to
the cross tube of the lower frame.
3. Using the 7/16" open end wrench, the ratchet, and the 7/16" socket, install
two washers (F), four bolts (E), and the four locknuts (C)
to secure the
hydraulic cylinder (I) to the side tubes of the lower frame.
4. Using the torque wrench, torque the nuts (A) and (C) to 65 + 10 in-lb
(7.3 + 1.1 N·m).
5. Using the 5/32" Allen™ wrench, install the pump linkage shoulder
bolt (G).
6. Using the torque wrench, torque the shoulder bolt (G) to 46 + 6 in-lb
(5.2 + 0.7 N·m).
7. Remove the cylinder rod hold-down assembly from the hydraulic
cylinder (I).
8. Install the base shroud and bellows (refer to procedure 4.25).

PC-100/PC-200 stretcher) are required to raise the stretcher to the high
position, purge the hydraulic cylinders as follows.
a. Push a release pedal, and lower the stretcher to the low position.
b. Hold a release pedal down, and pump a pump pedal approximately
30 times.
12. Raise the stretcher to the high position. If more than 28 pumps (24 for the
PC-100/PC-200 stretcher) are required to raise the stretcher to the high
position, repeat the purge procedure until the stretcher can be raised to the
high position with only 28 pumps (24 for the PC-100/PC-200 stretcher) or
less.
13. Lower the stretcher to the low position, and verify that the hydraulic
