Use l-beam trolley with lifting capacity of at least 3200 pounds (1452 kg) for M185 cannon or 3750

pounds (1701 kg) for M284 cannon to prevent injury to personnel.

Attach muzzle end of 30-foot cable or rope (4) horizontally to hoist (13) and a fixed point, or to a vehicle.

Keep 30-foot cable or rope tight.

Attach guide ropes to muzzle end of cannon tube (5).

As cannon tube is withdrawn horizontally, the hoist sustaining the weight of the cannon tube should

follow this movement to maintain the gun tube sling vertical and tight. Use care and withdraw slowly

to prevent damage.

NOTE

Withdraw cannon tube (5) from mount. Unhook muzzle end of 30-foot cable or rope (4). Place cannon tube
