SECTION 2 - OPERATION
2-10
RE-INSTALLING LOADER ON TRACTOR
CAUTION
Air in hydraulic lines and cylinders may cause
erratic operation until air is removed from
system.
Operate all controls carefully with slow engine
speed.
CAUTION
Keep hands and feet away from moving parts.
DO
NOT use fingers to check component or hole
and
pin alignment.
Use a drift or steel bar.
CAUTION
Prevent personal injury due to loader falling.
Make sure a bucket is installed on the loader
before the loader is installed on a tractor.
IMPORTANT: To prevent damage to tractor, keep it
centered between loader arms during installation.
Drive the tractor forwards carefully until the subframe
slowly enters the bearing boxes.
Connect the hydraulics. If there is any difficulty in
coupling the quick release couplings, this will be
because the oil pressure has not been relieved.
IMPORTANT: Never use force on quick release
couplings by striking the valve ball. This can damage
it so that coupling will not open when coupled
together. (Oil can only pass in one direction.) Make
sure that couplers are connected to their correspond-
ing point to complete the hydraulic circuit. If your
loader is fitted with a Quick Release Coupler system,
clean the connection surfaces prior to aligning the
guide pins and making the connection.

Extend the bucket cylinders (dump) to enable the
stationary pins to engage and seat into saddles of
subframe uprights. (Rear of bucket will come off
ground, loader will pivot about parking stands and
rear of loader will lower).
