General Instructions and Information
As with any piece of equipment, the care with which your loader is operated and maintained
will greatly affect it’s life and the safety of the people using it.
1. Keep all pivots well lubricated for longer bushing life. Inspect every 500 hours of operation
for wear.
2. Periodically check all bolts for tightness. If any bolt is damaged, replace it with a bolt of
equivalent grade or strength.
3. Follow the recommendations of the tractor manufacturer in regards to the quantity of oil used.
4. Check oil level frequently to ensure the system is full.
5. When making an oil check, be sure lift cylinders are retracted.
6. Before operating the loader, particularly if the loader is left standing for any length of time,
check the hydraulic system and oil level.
7. When installing hydraulics, follow the circuit carefully. See hydraulic hook-up section and
make sure the hoses do not contact any hot manifolds or sharp edges on tractor. After
assembly, raise the loader slowly and check to make sure that the hoses do not bind in all
positions.
CAUTION
The pressure of the relief and open center valves is set at the factory. Do not tamper with the
setting, serious injury to the operator or damage to the loader or tractor hydraulics may occur.
Warranty will be void if the loader is operated above recommended pressure.
9. When servicing any hydraulic components, care must be taken to prevent any foreign matter
from entering the system.
10. Do not neglect oil leaks. Leaks affect loader operation, are dangerous and can result in
personal injury or damage to the hydraulic system.
11. Never leave the cylinder shafts exposed when loader is not in use.
12. Worn or damaged components should be replaced as soon as possible with only the
manufacturer’s recommended component or equivalent.

Operation and Maintenance
GENERAL
Refer to tractor Operator’s Manual for Operating
information on the tractor’s hydraulic system.
Hydraulic systems using auxiliary valves should have
them located for easy reach from the tractor seat.
Hoses should be connected in such a manner that
pushing forward on valve handles lowers the boom or
dumps the bucket.
CAUTION: Always connect boom hoses to float
section.
Weight added to rear of tractor provides better traction
and an easier, more efficient loader operation. Extra
weight, along with widening the rear wheels, reduces
the risk of roll-over.
LOWER

DUMP
BUCKET
DUMP
BUCKET
LOWER

WARNING
The smaller the tractor is, the easier it will roll. We
recommend that weight be added to rear tires with
liquid or by the installation of rear wheel weights.
Where additional weight is required, a counterweight
box can be fabricated for tractors with three-point
hitches.
Extra weight can also be added by the use of a heavy
implement mounted to the three-point hitch.
A roll-over protective structure is also recommended.
In cold weather, operate the tractor’s engine at idle
speed until the hydraulic fluid is warmed up. High
engine speed when the hydraulic fluid is cold will
cause the pump to wear prematurely.
Under normal conditions, operate the tractor’s engine
at ½ throttle. Shift the tractor into a low gear before
entering a pile of material to minimize strain on loader
arms.
11
Page 14
Operating Suggestions for Loading
When handling heavy loads, be sure to lower
lift arms slowly. This is known as feathering
the hydraulic lever. If load is lowered too fast
and stopped suddenly, excessive shock loads
are created which can damage loader or
tractor.
When loading bucket, drive straight into
material. Attempting to turn tractor while
loading bucket can cause damage to both the
loader and tractor.
Come in level:
DO THIS! NOT THIS!
A straight bottom offers more resistance to lift.
NOTE: Bottom surface of bucket is parallel to
line on motion
Work both levers back to direct pressure to
both cylinders.
Combined action of lift and bucket cylinders
increases loading efficiency.
To increase loading efficiency, minimize angle of
turn and length to run between pile and
spreader.
Leave material which drifts over side of bucket
for final clean-up.
12
Page 15
Operating Suggestions
For Backfilling
DO THIS!
When backfilling approach pile with a flat
bucket. Leave dirt in bucket. Dumping on
each pass wastes time.
NOT THIS!
Backgrade work surface with a loaded
bucket. Release all pressure on lift cylinders
so full weight of bucket is scraping ground.
Use heel of bucket.
WARNING!
DO NOT USE LOADER
AS BATTERING RAM!
SAFETY: FIRST, LAST, ALWAYS
DO NOT use bucket in dumped position for
bulldozing. This will only impose severe
shock loading on the bucket cylinders and
make it more difficult to maintain a level
grade.

Attaching the Loader to Your Tractor
1. Position the tractor as centrally as possible and drive, using lowest gear possible, into the
loader frame until hoses can be connected.
2. Couple up the hydraulic hose lines to the loader or tractor valve ensuring proper function
(see Operator and Maintenance Section)
NOTE: When mounting the loader for the first time, slowly
work the cylinders back and forth, so that most of the air is
removed. Loosen the bolts on the hooks so that they can
be moved. Also, check that the nuts in the rear of the
subframes are in line with the holes.
3. On some tractors, the lift cylinders may have to be extended slightly,
so that the subframes can clear the front axle. Do not extend the
cylinders more than is required.
4. Drive the tractor ahead until the subframe is past the front axle and the front hook is close
to mounting boss.
WARNING! Check front grill clearance during
installation to avoid tractor damage.
5. Retract or extend the lift cylinders to line up the front hook with the mounting boss.
14

Attaching the Loader to Your Tractor
(Continued)
6. When the hook is lined up, dump or roll back the bucket to lower or raise the subframe
upright to align with the mounting boot.
7. Continue to drive the tractor forward until the subframe uprights are seated in the boot.
8. Secure the subframe uprights with the bolts and washers. Torque to 500 ft-lbs.
IMPORTANT: When mounting for the first
time, the front hook bolts will have to be
tightened after positioning the hook
directly over the mounting boss (most
rearward position).
9. Raise the loader and lock the support stand tubes into the up position.
NOTE: When mounting for the first time,
raise the loader slowly and check to make
sure that the hoses do not bind or become
pinched in all positions. Work the loader and
bucket up and down to work out all the air in
the hydraulics. Check and refill the tractor’s
hydraulic system.
15
Page 18
Removing the Loader from Your Tractor
WARNING! When removing the loader, it must be fitted with a bucket or
other suitable attachment to give the frame stability after removal. If this is
not done, the frame will not remain standing.
IMPORTANT! Always remove the loader on firm, level ground (away from
children’s play areas and high traffic areas). This makes attaching and
removing much faster and easier. It also makes the free standing loader
more stable.
1. Raise the loader, lower support stand tubes and lock into position
2. Lower the loader until the stand tubes are firmly on the ground and
then dump the bucket so that it is also firmly on the ground.
There should be slight downward pressure.
3. Loosen the bolts from the rear of the subframe boots and swing
bolt up into lock position.
16
Page 19
Removing the Loader from Your Tractor
(Continued)
4. Roll back the bucket slightly and simultaneously extend or retract
the lift cylinders to free hooks from spools. Then slowly back
up the tractor.
5. Once the subframe is clear of the boot and the hook is clear of the mounting boss, roll
back the bucket all the way. This raises the rear uprights of the loader.
NOTE: On some mountings, the lift cylinders
must be extended more while the tractor is
backing up, so that the subframes clear the
front axle.
6. Continue backing up until the loader is clear.
CAUTION! Be sure the hoses DO NOT get
pinched or catch on any frame members
while backing up.
7. After the loader is clear, retract the lift cylinders to protect the shafts and disconnect the
hydraulic lines at quick couplers.

General Notes and Instructions to the Operator
Regarding ALLIED TSL Loader Operations
1. The true self levelling system (TSL) utilizes mechanical linkages to
maintain bucket level while raising and lowering. The pivot plate
weldment, levelling tubes and linkages have been developed to ensure
that the bucket remains at the same position throughout its range of
motion. This feature is standard with 3.00” diameter bucket cylinders.
2. The TSL system incorporates a relief and anticavitation manifold to
provide extra dump at ground and rollback at full lift height. This feature is
available on 3.00” bucket cylinders only. If the loader is raised with the bucket fully dumped, oil from the bucket piston side will be bypassed at
high pressure to the bucket shaft side and the lift shaft side as the quick
attach contacts the dump stop. If the loader is lowered with the bucket fully rolled back, oil from the bucket shaft side will be bypassed at high
pressure to the bucket piston side and makeup will be provided by the lift
piston side as the quick attach contact the rollback stop. Note that these
two conditions are likely to occur intermittently and although the pump will
be forced to supply oil at a higher pressure, no damage to the loader
components will occur. It is, however, recommended to avoid the above
situations and keep the bucket somewhat level while raising or lowering
the loader for smoother operation.
3. The extra bucket stroke length allows for the bucket to be dumped to
approximately 90 degrees at ground. This allows for bucket assist when
traction is minimal. If the loader is raised from this position, the bucket will
retract as the quick attach contacts the dump stop and the circuit goes
through relief as described in note 2.
4. Extra bucket retraction allows for the bucket to be rolled back as the
loader raises. The TSL feature maintains the bucket level, but as required
the bucket can be manually rolled back approximately 20 degrees to allow
for increased bucket capacity. If the loader is lowered from this position,
the bucket will extend as the quick attach contacts the rollback stop and
the circuit goes through relief as described in note 2.
5. The relief valve is factory set at 3250 PSI cracking pressure and is
capable of bypassing 10-15 GPM. If loader lock-up should occur due to a
low tractor relief setting, higher inlet flows or return line restrictions, the
relief valve may be backed off slightly until the lock-up condition is
overcome (counterclockwise turn of set-screw). Contact the factory for
further instructions.
