QUICK-TACH
9. Turn OFF the shut off valves on the
level cylinders.
The level cylinders are equipped with valves that
keep the hydraulic fluid from leaking out of the cylin-
der. They must be turned so that they are perpen-
dicular to the valve.
10. Open the quick-tach lock assemblies.
If you have followed the previous steps, your
boom should already be located in position to unlock
the quick-tach lock assemblies.
DO NOT
open the
lock assemblies with the boom in the air!
To open the assemblies, simply pull the handle
(A) toward the center of the machine. Be sure that
they do not re-lock while attempting to remove the
boom in the next step.
11. Lower the transom to raise the quick-
tach hooks off of the quick-tach pins.
Lower the transom until the hooks have cleared
the pins.
You may notice a “bounce back” effect when the
weight of the boom has been relieved from the
machine. Once the airbags have cycled the ma-
chine will adjust to the new weight.
