OPERATING SYSTEMS
E. OPERATING THE QUICK-ATTACH SYSTEM
DISENGAGE THE LOCK ASSEMBLY
– Disengage
the lock pin assembly only after you have lowered the boom
close to the ground. DO NOT disengage while boom is in
the air!
To disengage the lock assembly (4.43-2), pull the pin
out as far as it will go. Once the pin is out as far as it will go,
it should lock in the out position. Make sure that the lock as-
sembly does not re-lock while you are trying to remove the
boom.

OPENING THE BOOM
– The booms must be partially open to keep them stable while off the machine .
Open the booms so that the stand on the end of the first section is even with the rear of the cab (fig. 4.43-1).
This position will allow the booms to sit level with the transom without causing too much stress on the
either part. It will also keep the weight from shifting too much either way (rearward or forward) which could
cause the boom to tip over or be difficult to connect or disconnect.

LOWER THE BOOM TO THE GROUND
– Slowly and
gently ease the boom to the ground.
Use the boom level function to try and make sure that all four
stands touch the ground at the same time. Continue to lower the
boom until the quick attach hooks have cleared the lock pin.
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 machine will adjust to the new weight.
