•
Lower the attachment until it is rmly resting on
a hard surface.
•
Close attachments with movable components
such as clamshells.
•
Actuate the attachment controls through the full
range of motion to release residual hydraulic
pressure.
•
If the attachment is equipped with integral sup-
ports, extend them to the support position.
•
Place the attachment only on a hard, even foun-
dation.
ENVIRONMENTAL NOTE
When uncoupling the hydraulic connections, hold
a pan under the optional hydraulics‘ quick couplers
to catch any oil that might run out. Dispose of it in
an ecologically sound way.
Uncoupling attachments
1. Lower the attachment.
2.
Stop the engine and actuate the control lever for the
attachment hydraulics several times in both directions
to release residual hydraulic pressure.
3.
Disconnect the hydraulic couplers and place covers over
the exposed ends to exclude foreign material.
4. Place the hydraulic hoses over the attachment.
5. Move the levers of the locking pins Item 3 (Fig. 39) up-
ward, so that the pins are pulled out of the tabs of the
attachment Item 4.
6.
Slightly lower the loader lift arms to disengage the upper
attachment support coupler halves. Activate the bucket
curl, rotating the lower portion of the loader frame cou-
pler away from the attachment coupler.
(This releases the receptacle frame item 1 (Fig. 39) from
the mounting brackets Item 2 (Fig. 39)).
7.
Back the loader away from the attachment if the recep-
tacle frame is free.
