Hydraulic Safety

Escaping fluid under pressure can have sufficient force to penetrate
the skin, causing seroius personal injury. Before repairing, adjusting,
or disconnecting lines, be sure to relieve all pressure.

Before applying pressure to the system, be sure all connections are
tight and the lines, pipes and hoses are not damaged.

Wear proper hand and eye protection when searching for leaks. Use
a piece of wood or cardboard instead of hand to check for leaks.

Maintain all components in good working order.

If injured by escaping fluid, see a doctor at once. Serious infection
or toxic reaction can develop if proper medical treatment is not
administered immediately.

WARNING

Read the following safety information

WARNING

Tractor power steering must work normally when
operating the loader.

CAUTION

Only qualified personnel should perform these
procedures. Damage to the hydraulic system may
occur unless properly installed.

Instructions

1. If the right and left hand brackets (13 & 14) weren’t placed on the axle mounts when the mount
kit was installed, do so now. See Graphics 1 & 2.

2. Assemble the bulkhead plate (1) to the plate on the RH mount as shown in Graphic 3, using the
M10 nuts and bolts provided (2 & 4).

3. Place one snap ring (6) in the second slot on each of the four female quick couplers (10). Place
the quick couplers in the bulkhead facing forward. Place another snap ring on each of the four
quick couplers to secure them in the bulkhead. See Graphics 3 & 4.

4. Place one of the colored caps on each of the female quick couplers.

5. Place two 90° elbows (5) in the two inside quick connectors. For a 952, place two more 90°
elbows on the outside quick connectors also. For a 1220, place the two 45° elbows (20) on the
outside two quick couplers.

6. Starting at the right hand side of the tractor, feed the 80" hoses (12) down the inside of the
mount between the axle bar and tension rod, then cross under the tractor and up through the
left hand mount to the quick couplers under the step.

7. Place one piece of the 2.88" diameter nylon sleeves (25) over the two 80" hoses on the right
hand side. Then assemble both hoses to inner elbows of the bulkhead plate assembly.

8. Loosely assemble two P-clamps (15) on the hoses and bolt to the bracket on the right hand side
using the one of the bolts and nuts provided (16 &17). See Graphic 1. Repeat on the left hand
side. See Graphic 2.

9. Loosely assemble two P-clamps (15) on the bracket extending from the underslung using one
of the bolts and nuts provided (16 & 17). See Graphic 1

10. On the left hand end of each of the two 80" long hoses, place a 90° elbow (5) and then place a
male quick coupler (11) on the Morb end of the elbow. (Note that there are two styles of male
quick couplers in the hose kit. The Pioneer couplers (7) are used with the female quick couplers
on the bulkhead plate.)

11. Place the remaining 2.88" diameter nylon sleeve (25) over this end of the hoses. Then connect
the male quick couplers to the quick couplers underneath the step.

12. Check the hose routing to make sure it is clear of any sharp edges and the threaded tension
rods. If necessary, the P-clips on the two brackets can be moved to either hole or either side of
the bracket to get the required clearance. Tighten the hardware on the P-clips.

13. On each of the 24" hoses (18) place a 90° elbow (5) and then place a male quick connect coupler
(11) on the Morb end of the elbow. Connect the female JIC end of the hose to the remaining
fittings in the outside quick couplers in the bulkhead plate. Connect the male quick couplers to
right hand quick couplers under the cab.

14. Build the assembly of components around the locking valve as shown in Graphic 4. When
completed the assembly is placed in the top inside quick connector for 1220 (the top outside
for 952).

15. Place a straight male adaptor (19) on the remaining three male Pioneer quick couplers (7) and
connect to the end of the 90° end of the 51" hoses (21) on each of the couplers.

16. Place the 3.88" diameter nylon sleeve (26) over the MJIC end of hoses and slide to the 90°
fittings.

17. Slide the 43" hose (23) into the nylon sleeve making sure all the MJIC fittings are on the same
end.

18. Feed the hoses through the loop on the bottom of the liftarm and route to the tubelines on the
inside of the liftarm. (If the loader is not yet installed, do so now - consult loader manual for
further instruction.)

19. Connect the female JIC end of the 43" hose to the fitting on the top of ball valve and the MJIC
end of the hose to the lower of the four tubelines on the inside of the liftarms.

20. Connect the MJIC ends of the remaining hoses to the tubelines.. The hose that is connected
to the fitting below the ball valve should be connected to the tubeline that is second from the
bottom. The remaining two hoses get connected to the top two tubelines. Leave the quick
couplers unconnected at this time..

21. All the hoses are now in place. Adjust the fit of the hoses in nylon sleeves and secure the
sleeves with ty-wraps provided.

22. Connect the quick couplers at this time. On the 1220 the quick couplers for the lift cylinders
are on the left hand side. On the 952 they are on the right hand side. Move the quick couplers
(either at the bulkhead plate or at the tractor quick couplers) up or down to get the correct
loader operation.

23. Tighten any remaining hardware or connections once suitable routing for all hoses is found.
Loader is now ready for operation.
