2 CONTROLS
To drive the loader in reverse in a straight line, move both
control levers back the same amount.
The loader is turned by moving one lever further forward
than the other. To turn right move the left lever further than
the right lever, to turn left move the right lever further than
the left lever.
For the loader to turn or “skid-steer” within its own length,
one lever is moved forward and the other back. This causes
the wheels on one side to turn forward and the wheels on
the other side to reverse, turning the loader.
2. 7 HAND CONTROLS
Hand controls to operate the loaders boom and bucket
hydraulic system as well as control the loader travel speed
and direction are available as a factory installed option.
BUCKET CONTROL
The right hand lever controls the bucket tilt cylinders. (Fig. 2.
7A) Moving the control lever to the right will cause the bucket
cylinders to extend, dumping the bucket. Moving the control
lever to the left will cause the bucket cylinders to retract,
rolling the bucket back.
BOOM CONTROL
The left hand lever controls the boom lift cylinders. (Fig. 2.
7A) Moving the control lever to the left will cause the boom
cylinders to extend, raising the loaders boom arms. Moving the
control lever to the right causes the boom cylinders to retract,
lowering the boom. Moving the control lever to extreme right
will place the boom in float position. This allows the bucket to
follow the contour of the ground as the loader moves
backward.
When the control levers are released, they will automatically
return to the neutral position stopping all hydraulic movement
and travel speed. Before exiting the loader, shut off the engine
and ground the attachment by lowering the boom completely
down to the frame. Raise the seat bar to the locked position.
Move both control levers forward and backward to ensure the
steering controls are locked and move both levers to the left
and right to ensure the hydraulic controls are locked before you
get out of the loader.
AUXILIARY HYDRAULICS:
The foot pedal is used to engage the loaders auxiliary hydraulic
circuit to power an attachment such as a post hole auger. (Fig.2.
8A) Pressing on the toe of the pedal provides hydraulic flow to
the female quick-connect coupling located at the front of the
boom arms. Firm pressure on the toe of the pedal will lock it
into detent position providing a continuous flow of hydraulic
oil to the attachment. Pressing on the heel of the pedal provides
hydraulic flow to the quick-connect coupling reversing the
flow of hydraulic oil. If not locked in detent position, releasing
the pedal will cause it to return to the neutral position stopping
all hydraulic flow. Once the pedal is locked in detent, it can be
returned to neutral by tapping the heel of the pedal.
C 3250 Fig. 2. 6A
To avoid personal injury,
lower the boom arms, shut
off the engine, raise the
seat bar and cycle the
hydraulics to ensure they

be difficult or impossible and damage to the starter motor may
occur.
2. 8 ELECTRICAL AUXILIARY
CONTROL
Auxiliary Hydraulic (solenoid operated – optional). A switch
located in the L.H. steering control lever (Fig. 2 .8A) is used to
engage the loaders auxiliary hydraulic circuit to power
attachments such as post hole augers, sweepers, etc. By
pressing and holding the switch in position 1 (Fig. 2. 8A)
provides hydraulic flow to the female quick connect coupling
located at the front of the boom arms (Fig. 2. 8B). Releasing
the switch returns the auxiliary hydraulic circuit to neutral,
stopping hydraulic flow.
By pressing and holding the switch in position 2 (Fig. 2. 8A)
provides hydraulic flow to the male quick connect coupling
located at the front of the boom arms (Fig. 2. 8A). Releasing
the switch returns the auxiliary hydraulic circuit to neutral,
stopping hydraulic flow.
For continuous flow to the auxiliary hydraulic circuit, a push-
pull switch is located on the R.H. side of the instrument panel.
Placing the push-pull switch in the ON position provides
continuous hydraulic flow to the female quick connect
coupling located at the front of the boom arms (Fig. 2.8A). To
stop hydraulic flow to the auxiliary hydraulic circuit, return the
push-pull switch to the OFF position. When the push-pull
switch on the instrument panel is in the ON position, the switch
located in the L.H. control lever is not operable.
Return the auxiliary
hydraulic foot pedal to
neutral position when not
in use.

When the auxiliary circuit is not in use, and before starting the
loader, ensure the push-pull switch located on the R.H. side of
the instrument panel is in the off position, otherwise starting
the loader may be difficult or impossible and damage to the
starter may occur.
This machine is equipped with electric solenoid controlled
auxiliary hydraulics, if for any reason the loader stops or looses
current when the electric solenoid is engaged, it can be
disengaged by simply turning off the switch located in the
upper panel, or by depressing the poppet located at either end
of the control valve. (See Fig. 2. 8C).
2. 9 FOOT PEDALS
Operation of the boom lift cylinders, bucket tilt cylinders
and auxiliary hydraulic circuit are controlled by foot pedals
(Fig. 2. 9) connected to a hydraulic control valve. The
hydraulic control valve is a series type valve which allows
simultaneous use of both the boom lift and bucket tilt
circuits. The control valve is equipped with a relief valve for
circuit protection.
Boom Lift – The L.H. pedal is the boom lift control (Fig. 2.
9). To raise the boom press on the heel (2) of the pedal. To
lower the boom press on the toe (1) of the pedal. Firm pressure
on the toe (2) of the pedal will lock the boom in float position.
This allows the bucket to follow the ground as the loader
moves backward.
Auxiliary Hydraulics – The center pedal is used to engage
the auxiliary hydraulic circuit to power an attachment such as
an auger. Pressing on the toe (3) of the pedal provides hydraulic
pressure to the female quick - connect coupling located at the
front of the boom arms.
Firm pressure on the toe (3) of the pedal places the valve in
detent position providing a continuous flow of hydraulic oil to
the attachment. Pressing on the heel of the pedal (4) provides
hydraulic pressure to the male quick-connect coupling
reversing the flow of hydraulic oil. When the auxiliary circuit
is not in use return the foot pedal to neutral position, otherwise
starting the loader may be difficult or impossible and damage
to the starter may occur.
Bucket Tilt – The R.H. pedal is the bucket tilt (dump)
control. Pressing on the toe (5) of the pedal will dump the
bucket. Pressing on the heel (6) of the pedal will roll the bucket
back.

3. 1 STARTING INSTRUCTIONS
3. 1A Pre - Starting Inspection:
Before starting the loader complete the following
inspection:
1. Check the hydraulic oil level, engine oil level, engine
coolant level and fuel supply.
2. Check the air filter indicator.
3. Check for fuel, oil and hydraulic leaks.
4. Check lights, battery level and cables.
5. Check tire pressure:
Standard . . . . 50 PSI (345 kPa)
Flotation . . . . 40 - 45 PSI (276 - 310 kPa)
6. Check wheel nut torque 80-90 ft. lbs. (109 - 122 Nm)
7. Lubricate all grease fittings.
8. Check the condition and operation of all safety decals
and equipment – Ensure all shields and safety screens
are in place. If necessary, repair or replace before
starting.
(For complete daily servicing Refer to Section 4. 3).
3. 1B Starting Procedure :
1. Ensure the seat bar is in the UP position and the
steering controls are centered and the foot pedals
locked.
2. Adjust and fasten the seat belt securely around you.
3. Place the throttle control in idle position.
4. Turn the ignition key counterclockwise to activate the
glow plugs. Hold approximately 15 seconds. Both the
alternator and engine oil pressure warning lights
should be on.
5. Turn the key clockwise to start position to engage the
starter. Do not crank the starter for more than 15
seconds. If the engine fails to start, turn the key
counter clockwise and pre-heat again.
6. When the engine has started the engine oil pressure
and alternator warning lights should go out. If they
don’t, shut-off the engine immediately and determine
cause.
7. Allow the engine to warm up for five minutes before
operating. When ready to operate, lower the seat bar
and advance the throttle to full on position.
3. 1C Shut-Off Procedure:
1. Park the loader on level ground. If it is necessary to
park on a slope, position the machine at right angles to
the slope.
2. Lower the lift arms and ground the attachment.
3. Return the throttle control to idle position. If the
engine is hot, allow it to idle until cool, at least 2
minutes. (See Section 2. 5).
4. When the engine is cool, turn the ignition key to the
OFF position and remove the key.
.5. Place the auxiliary foot pedal in neutral position. If the
auxiliary foot pedal is left in detent, restarting the
machine may be impossible. If equipped with electro
solenoid, make sure the switch is in the OFF position.
6. Raise the seat bar to apply the park brake. Turn the
ignition switch to the OFF position, unfasten the seat
belt, and ensure the pedals are locked by rocking them
and ensure the steering levers are locked in neutral.
3 OPERATION
To prevent personal
injury do not start the
engine unless you are in
the seat with the seat belt
fastened around you.
WARNING
This engine is equipped
with glow plugs. Do not
use ether or any high
energy fuels to assist
starting.
IMPORTANT
To avoid personal injury,
lower the boom arms, shut
off the engine, raise the
seat bar and cycle the
hydraulics to ensure they
are locked. Then, unlatch
the seat belt and exit the
loader. Do not enter or exit
with the engine running
unless as specified in this
manual or under specific
service and backhoe
operating procedures.
WARNING

18
3. 1D Manual Shutoff Procedure
1. Should the engine fail to stop after following the
procedure described in Section 3.1 - C, ensure that the
lift arms are lowered and grounded and the foot pedals
and steering levers are locked.
2. Exit the machine and open the rear engine compartment
access door. Pull the manual stop lever (Fig 3. 1D) and
hold until the engine has stopped. (See Section 4. 11A,
Electrical System Troubleshooting Guide).
3. 2 OPERATING PROCEDURE
1. When learning to use the loader operate at a slow rate.
2. Take advantage of the efficient operation of the loader.
Keep the travel distance as short as possible. Keep the
work area small so the cycle time is short.
3. Keep the work area as level as possible.
4. Decrease cycle time by “skid” turning (See Section
2.6) rather than a go backward-go forward turn.
5. Fill the bucket to rated capacity. Turning is easier with
a full load than with a partial load. Keep the loaded
bucket close to the ground when transporting.
6. Tilt the bucket as you raise the boom arms or drive up
a slope. This will prevent material from falling off the
back of the bucket.
7. Do not drive across a slope. Always go up or down a
slope with the heavy end of the loader pointing up
towards the top of the slope.
3. 3 FILLING FROM A PILE
Push down on the toe of the boom arm pedal and lower the
boom completely down. Push the toe of the bucket pedal and
place the cutting edge of the bucket on the ground (Fig. 3.
3A). For hand control units, move the L.H. control lever
towards you and lower the boom completely down. Move the
R.H. control lever away from you (Fig. 3. 3A) and place the
cutting edge of the bucket on the ground.
3 OPERATION
Always let the engine
warm completely before
you begin operation each
day.
IMPORTANT
To avoid personal injury,
lower the boom arms, shut
off the engine, raise the
seat bar and cycle the
hydraulics to ensure they
are locked. Then, unlatch
the seat belt and exit the
loader. Do not enter or exit
with the engine running
unless as specified in this
manual or under specific
service and backhoe
operating procedures.
