Operation

1. Release cannon tube (2) from travel lock (25) and position cannon tube at the same elevation as

when held by travel lock. Slow travel lock (see figure B-4).

2. Place chalk markings on cannon tube (2) 12 and 14 inches (30.4 and 35.5 cm) from front of dust

cover (5).

•

Breech must be closed prior to pumping to prevent damage to operating cam rollers.

•

Longer of the two recoil exerciser cable assemblies must clear top plate of the replenisher

(M109A6).

3. Close breech (29).

WARNING

Cylinder support assembly has moving parts. Keep clear of cylinder support assembly

during operation to avoid injury.

NOTE

•

The electric hydraulic pump has a three position REMOTE ON-OFF-MOMENTARY ON

switch. To operate the electric hydraulic pump using the remote control, place the

REMOTE ON-OFF-MOMENTARY ON switch in the REMOTE ON position. To operate

the electric hydraulic pump without the remote control, hold the REMOTE ON-OFF-

MOMENTARY ON switch in the MOMENTARY ON position.

•

Make sure quick disconnect couplings are fully seated.

4. If using electric hydraulic pump (22), place manual valve (27) in upright position. Using the electric

hydraulic pump, begin pumping. During pumping, check for hydraulic leaks. If leaks are found,

slowly release hydraulic pressure and replace defective parts (see figure B-5).

5. Continue pumping until front of dust cover (5) is between the chalk markings.

6. Inspect buffer piston rod (28) for discoloration. If no discoloration is found, skip to step 9.
