3. Slowly extend the Dynattach system and lower the
hooks under the attachment tool hookup bar.
4. Tilt the Dynattach system back so that the lock
plate engages the attachment tool. This secures the
attachment tool to the Dynattach system.
5. For attachment tool with auxiliary hydraulics, con-
nect hoses to the quick-connect connectors on the
boom nose.
Detaching
To detach attachment tool, proceed as follows:
1. Raise the boom slightly and extend it 2 to 3 feet
(0.6 m to 0.9 m) for better visibility. Lower the boom
until the attachment tool is approximately 12” (0.3 m)
off the ground.
2. Roll the carrier backward as far as it will go. Once
the carrier is rolled all the way back, perform the
MANDATORY SAFETY SHUTDOWN PROCE-
DURE (Safety chapter, p.10)
3. With the engine off, leave the operator’s station.
Manually raise the lock spring and flip the Lock Plate
up and outward at least 180
o
so it is in position to re-
lock on the next attachment tool.
4. If the attachment tool has auxiliary hydraulics, dis-
connect the hoses from the quick-disconnects on the
boom nose.
5. Start the engine.
6. Tilt the Dynattach system forward to allow the
attachment tool to roll out, then lower the boom so the
hook ears clear the hookup bar on the attachment tool.
Back the machine until the attachment tool is free of
the Dynattach system.
NOTE:
One side of the lock plate has a bright
red decal to indicate the unlocked position.
SELF-LEVELING
The machine is provided with a hydraulic self-leveling
feature. This feature is designed to keep the attachment
tool level while the boom is being raised.
