Push the two lift arm support pin handles located directly in front of the operator at the top of the operator compartment (Fig. 2.6A) outward extending the lift arm locking pins (Fig. 2.6B). Slowly lower the lift arms down onto the pins. To retract the support pins, first lift the lift arms off of the pins before retracting.
2. 8 STEERING CONTROLS
The two steering levers control speed, direction and turning of the loader. The R.H. lever controls the wheels on the R.H. side of the loader and the L.H. lever the L.H. wheels. Loader speed is controlled by the amount each lever is moved from centre or neutral position. (Fig. 2.7A) The further away from neutral the faster the travel speed. For maximum power and slow travel speed move the control levers only a small amount.
To drive the loader forward in a straight line, move both control levers forward the same amount (Fig. 2.7B).
To drive the loader in reverse in a straight line, move both control levers back the same amount (Fig. 2.7B).
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 (Fig. 2.7B).
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 (Fig. 2.7B).
Fully retract the lift arm
supports before raising
or lowering lift arms.

2.9 ELECTRIC SOLENOID AUXILIARY CONTROLS
Auxiliary hydraulics (solenoid operated - standard)
A switch located on the L.H. steering control lever (Fig. 2.8A) is used to engage the loader’s auxiliary hydraulic circuit to power attachments such as post hole augers, sweepers, etc. 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 lift arms (fig. 2.9C). Releasing the switch returns the auxiliary hydraulic circuit to neutral, stopping the hydraulic flow.
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 lift arms (fig. 2.8C). releasing the switch returns the auxiliary hydraulic circuit to neutral, stopping hydraulic flow.
For continuous flow to the auxiliary hydraulic circuit, a toggle switch is located on the L.H. instrument panel (fig. 2.8B). Placing the switch in the “ON” position provides continuous hydraulic flow to the female quick connect coupling located at the front of the lift arms (fig. 2.8C). To stop hydraulic flow to the auxiliary hydraulic circuit, return the switch to the “OFF” position (fig. 2.8B). When the switch on the instrument panel is in the “ON” position, the switch located in the L.H. control lever is not operable.

2.10 FOOT CONTROLS
Operation of the lift cylinders and the bucket tilt cylinders are controlled by the foot pedals (fig. 2.10) connected to a hydraulic control valve. The hydraulic control valve is a series type valve which allows simultaneoous use of both the lift and bucket tilt circuits.
Lift –
The L.H. pedal is the lift control (Fig. 2.10). To raise the lift arms press on the heel (2) of the pedal. To lower the lift arms press on the toe (1) of the pedal. Firm pressure on the toe (1) of the pedal will lock the lift arms in float position. This allows the bucket to follow the ground as the loader moves backward.
Bucket Tilt –
The R.H. pedal is the bucket tilt (dump) control. Pressing on the toe (3) of the pedal will dump the bucket. Pressing on the heel (4) of the pedal will roll the bucket back.
2. 11 HAND CONTROLS
Hand controls to operate the loader’s lift arm and bucket hydraulic system as well as the loader’s travel speed and direction are available. Refer to previous section for instructions on steering controls.
LIFT ARM AND BUCKET CONTROLS
The right hand lever controls the bucket tilt cylinders (2.11). Moving the control lever to the right causes the bucket to dump. Moving the lever to the left rolls the bucket to the carry position.
Moving the left hand control lever (Fig. 2.11) to the left will cause the lift cylinders to extend, raising the loader’s lift arms. Moving the control lever to the right causes the lift cylinder to retract, lowering the lift arms. Moving the control lever to the extreme right will place the lift arms in the 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, lower the lift arms completely down to the frame and ground the attachment. Then shut off the engine. Move both levers to the left and right to ensure the hydraulic controls are locked before you get out of the loader.
2. CONTROLS
To prevent personal
injury do not operate the
loader without lowering
the safety bar, fastening the seat belt and keeping feet on the control pedals
or the cab floor.
WARNING
To avoid personal injury,
lower the lift arms, shut
off the engine, raise the
seat bar and cycle the

3.1 STARTING INSTRUCTIONS
1. 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 for fuel, oil and hydraulic leaks.
(3) Check lights, battery level and cables.
(4) Check tire pressure:
10.00 x 16.5 . . . . 40 - 45 PSI (276 - 310 kPa)
(5) Check wheel nut torque 100 - 110 ft. lbs. (136- 149
Nm).
(6) Lubricate all grease fittings.
(7) 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.
2. Starting Procedure – Diesel
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 counter clockwise 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. Shut-Off Procedure
(1) Park the loader on level ground. If it’s 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 normal. At least 2 minutes.
(4) When the engine is cool, turn the ignition key to the
OFF position and remove the key.
(5) Never enter or exit the loader when the engine is
running.
(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 hydraulic controls are locked by rocking them.
This engine is equipped
with glow plugs. Do not
use ether or any high
energy fuels to assist
starting.

lower the lift arms, shut off
the engine, raise the seat bar
and cycle the hydraulic
controls to ensure they are
locked. Then, unlatch the seat
belt and exit the loader. Do
not enter or exit with the

3. 2 OPERATING PROCEDURES
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
2.7) 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 lift 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 lift arm pedal and lower the lift arms completely down (Fig. 3.3A). Push the toe of the bucket pedal and place the cutting edge of the bucket on the ground. For hand control units, move the L.H. control lever towards you and lower the lift arms 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.
Drive the loader forward slowly. As the bucket begins to fill push on the heel of the bucket pedal to raise the front of the bucket (Fig. 3.3B) and push on the heel of the lift arm pedal to raise the lift arms. When the bucket is full back away from the pile. For hand control units, move the R.H. control lever towards you to raise the front of the bucket, and move the L.H. control lever away from you to raise the lift arms (Fig.
3.3B). When the bucket is full back away from the pile.
To dump the bucket (Fig. 3.3C) push down on the heel of the lift arm pedal to raise the lift arms. Push down on the toe of the bucket pedal small amounts as the lift arms are raising to stop material from falling off the back of the bucket. When the bucket is at the correct height for dumping, push on the toe of the bucket pedal to empty the bucket.
For hand control units, move the L.H. control lever away from you (Fig. 3.3C) to raise the lift arms. Move the R.H. control lever away from you in small amounts as the lift arms are raising to stop material from falling from the back of the bucket. When the bucket is at the correct height for dumping, move the R.H. lever away from you to empty the bucket.
* Hand controls not available on all machines.
Always let the engine
warm completely before
you begin operation each
day.

3. 4 DIGGING WITH A BUCKET
Push on the toe of the lift arm pedal and lower the lift arms completely down. Push on the toe of the bucket pedal and place the cutting edge of the bucket on the ground (Fig.
3.4D). Drive the loader forward at a slow rate and continue to tilt the bucket down until it enters the ground.
Push down on the heel of the bucket pedal (Fig. 3.4E) to increase traction and keep an even digging depth.
Continue to drive forward until the bucket is full. When digging in hard ground, it is easier to raise and lower the bucket cutting edge with the tilt pedal while slowly driving forward. When the bucket is full, push down on the heel of the bucket pedal (Fig. 3.4F) to raise the tip of the bucket.
For hand control units, move the L.H. control lever towards you to lower the lift arms completely down. Move the R.H. control lever away from you and place the cutting edge of the bucket on the ground (Fig. 3.4D). Drive the loader forward at a slow rate and continue to tilt the bucket down until it enters the ground. Move the R.H. control lever towards you (Fig.
3.4E) to increase traction and keep an even digging depth. Continue to drive forward until the bucket is full. When the bucket is full, move the R.H. control lever towards you (Fig.
3.4F) to raise the tip of the bucket.
