2. 7 STEERING CONTROLS
The two steering levers control speed, direction and turning the loader. The R.H. lever controls the wheels on the R.H. side of the loader and the L.H. lever controls the wheels on the left hand side of the loader. The 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. 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)
2.8 HAND CONTROLS (OPTIONAL)
Hand controls to operate the loaders lift arm and bucket hydraulic system as well as the loaders travel speed and direction are available. Refer to section 2. 7 for instruction on steering controls.

2...CONTROLS
LIFT ARM and BUCKET CONTROLS:
The right hand lever controls the bucket tilt cylinders (Fig. 2. 8A). Moving the left hand control lever to the left will cause the lift cylinders to extend, raising the loaders lift arms. Moving the control lever to the right causes the lift cylinders to retract, lowering the lift arms. Moving the control lever to extreme right will place the lift arms 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 lower the lift arms completely down to the frame and ground the attachment. Raise the seat bar to the locked position. 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.
Pressing on the toe of the pedal provides hydraulic flow to the female quick - connect coupling located at the front of the lift 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.
When the auxiliary hydraulic system is not in use return the pedal to the neutral position otherwise starting the loader may be difficult or impossible and damage to the starter motor may occur.
To prevent personal
injury do not start the
engine unless you are in
the seat with the seat belt
fastened around you.
WARNING
Return the auxiliary
hydraulic
foot pedal to
neutral position when not
in use.

ELECTRICAL SOLENOID AUXILIARY (OPTIONAL)
A switch located in the L.H. steering control lever (Fig. 2. 9A) is used to engage the loaders auxiliary hydraulic circuit to power attachments such as post hole augers, sweepers etc.
CONTROLS:
By pressing and holding the switch in position 1 (Fig. 2. 9A) provides hydraulic flow to the female quick connect coupling located at the front of the lift arms (Fig. 2. 9B). Releasing the switch returns the auxiliary hydraulic circuit to neutral, stopping hydraulic flow.
By pressing and holding the switch in position 2 (Fig. 2. 9A) provides hydraulic flow to the male quick connect coupling located at the front of the lift arms (Fig. 2. 9B). 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 Instrument Panel. 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. 9B). To stop hydraulic flow to the auxiliary hydraulic circuit, return the switch to the “OFF” position. When the switch on the instrument panel is in the ON position, the switch located in the L.H. control lever is not operable.
NOTE: The optional left hand control lever auxiliary control switch operates a horn, if equipped.
To avoid personal injury,
lower the lift 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.

When the auxiliary circuit is not in use and before starting the loader, ensure the switch located in the. instrument panel is in the off position, otherwise starting the loader may be difficult or impossible and damage to the starter may occur. If for any reason the loader stops or loses 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 (Fig. 2.9B).
2.10 FOOT PEDALS
Operation of the lift cylinders, bucket tilt cylinders and auxiliary hydraulic circuit are controlled by foot pedals (Fig. 2. 10) connected to a hydraulic control valve. The hydraulic control valve is a series type valve which allows simultaneous 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.
Auxiliary Hydraulics –
The center pedal is used to engage the auxiliary hydraulic circuit to power an attachment such as a backhoe. Pressing on the toe (3) of the pedal provides hydraulic pressure to the female quick - connect coupling located at the front of the lift 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.
To avoid personal injury,
lower the lift 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

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 (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).

3. 11 LOWERING LIFT ARMS (ENGINE OFF)
In the event that you should have an electrical failure which renders your skid steer inoperable with the lift arms up, the following procedures would apply.
1. Lift Arm Height Is Sufficient To Engage Lift Arm Support Pins
Engage lift arm support pins. (Fig. 3. 11A) Raise seat bar and cycle all controls to ensure they are locked. Exit loader and open rear door. Locate the control valve on the right side of the machine. Unplug the electrical wire and remove the knurled nut holding the solenoid on the spool lock. Remove the solenoid, then remove the lock pin and spring assembly. (Fig. 3. 11B2) Once the lock pin and spring are removed, the lift arm spool is free to travel. Enter the machine, being careful not to cycle the foot pedals or the control levers as the locking system has been disabled. Once in the operator seat, lower the safety bar, and dis­engage lift arm support pins. Move the lift arm pedal or control lever to lower the lift arms to the ground.
2. Lift Arm Height Is Not Sufficient To
Engage Lift Arm Support Pins
DO NOT EXIT FROM FRONT OF LOADER WITHOUT LIFT - ARMS ON GROUND OR SUPPORTED BY ACCEPTABLE MEANS!
Raise seat bar and cycle all controls to ensure they are locked. If help is readily available, have some one place a suitable support under the lift arms (e.g. 4” x 4” Lumber) or a piece of angle iron between lift cylinder end cap and lift cylinder rod mount.
Then exit loader using extreme caution. If help is not available, the operator must exit the loader from the rear window and perform the proper lift arm supporting (As described previously). Once this is completed, open rear door. Locate the control valve on the right side of the machine. (FIG. 3. 11B1) Unplug the electrical wire and remove the knurled nut holding the solenoid on the spool lock. Remove the solenoid, then remove the lock pin and spring assembly (Fig. 3. 11B2). Once the lock pin and spring are removed, the lift arm spool is free to travel.
Ensure assistance is available, then the operator can enter the machine, being careful not to cycle the foot pedals or the control levers as the locking system has been disabled. Once in the operator seat, lower the safety bar. Have the assistant remove the lift arm support devices. The operator can then move the lift arm pedal or control lever to lower the lift arms to the ground.

4.10 TIRE MAINTENANCE
1. Tire Inflation and Service
1. 1 Upon receiving your loader, check the air pressure in the tires as indicated in the table.
1. 2 Check tire pressure every 50 hours or weekly.
1. 3 Tire inflation pressure affects the amount of weight which a tire may carry. Do not over or under inflate the tires.
1. 4 Do not inflate a tire above the manufacturer’s maximum pressure shown on the tire or the maximum pressure shown in the table.
1. 5 Do not re - inflate a tire that has been run flat or seriously under - inflated until the tire has been inspected for damage by a qualified person.
1. 6 When checking tire pressure, inspect the tire for damaged side walls and tread cuts. Neglected damage will lead to early tire failure.
1. 7 Be sure the rim is clean and free of rust.
1. 8 Lubricate both tire beads and rim flanges with soap solution. Do not use oil or grease.
1. 9 Use a clip - on tire chuck with a remote hose and gauge which allows the operator to stand clear of the tire while inflating it.
1. 10 After seating the beads, adjust inflation pressure to recommended operating pressure.
1. 11 Do not inflate a tire unless the rim is mounted on the loader or is secured so that it will not move if the tire or rim should suddenly fail.
1. 12 Do not weld, braze or otherwise repair a rim. Do not use a damaged rim.
1. 13 Never attempt tire repairs on a public road or highway.
1. 14 Use jack stands or other suitable blocking to support the loader while repairing tires.
1. 15 Insure jack has adequate capacity to lift your loader.
1. 16 Insure jack is placed on a firm level surface.
1. 17 Do not put any part of your body under the loader or start the engine while the loader is on the jack.
1. 18 Torque lug nuts to specification after reinstalling wheel. Check lug not torque hourly until torque stabilizes.
Tire Inflation Table
Tire Inflation Pressure
8.50 x 15.0 30 - 35 PSI (207 - 241 kPa)
10.50 x 15.0 30 - 35 PSI (207 - 241 kPa)
2. Tire Rotation
The front and rear tires will wear at different rates. For even wear move the front tires to the rear and the rear tires to the front when wear is first noticed.
If two tires become worn more than the other two put the two worn tires on the same side.
When new tires are installed, always keep tires the same size on the same side of the loader. Two different size tires on the same side of the loader will cause drive chain wear, tire wear and a loss of power.
