During Operation
¾ Machine stability is affected by: the load being carried, the height of the load,
machine speed, abrupt control movements and driving over uneven terrain.
DISREGARDING ANY OF THESE FACTORS CAN CAUSE THE
LOADER TO TIP, THROWING THE OPERATOR OUT OF THE
SEAT OR LOADER, RESULTING IN DEATH OR SERIOUS INJURY.
Therefore: ALWAYS operate with the seatbelt fastened and the restraint bar
lowered. Do not exceed the machine’s Rated Operating Load. Carry the load
low. Move the controls smoothly and gradually, and operate at speeds appro-
priate for the conditions.
¾ When operating on inclines or ramps, always travel with the heavier end of
the loader toward the top of the incline for additional stability.
¾ Do not raise or drop a loaded bucket or fork suddenly. Abrupt movements
under load can cause serious instability.
¾ Never activate the float function with the bucket or attachment loaded or
raised, because this will cause the lift arm to lower rapidly.
¾ Do not drive too close to an excavation or ditch; be sure that the surrounding
ground has adequate strength to support the weight of the loader and the load.
¾ Never carry riders. Do not allow others to ride on the machine or attachments,
because they could fall or cause an accident.
¾ Always look to the rear before backing up the skid-steer loader.
¾ Operate the controls only from the operator’s seat.
¾ Always keep hands and feet inside the operator’s compartment while oper-
ating the machine.
¾ New operators must operate the loader in an open area away from bystanders.
Practice with the controls until the loader can be operated safely and
efficiently.
¾ Always wear safety goggles and head protection while operating the
machine. Operator must wear protective clothing when appropriate.
¾ Exhaust fumes can kill. Do not operate this machine in an enclosed area
unless there is adequate ventilation.
¾ When you park the machine and before you leave the seat, check the restraint
bar for proper operation. The restraint bar, when raised, deactivates the lift/tilt
controls and auxiliary hydraulics, and applies the parking brake.
Maintenance
¾ Never attempt to by-pass the keyswitch to start the engine. Use only the
jump-starting procedure detailed in the Operation chapter of this manual.
¾ Never use your hands to search for hydraulic fluid leaks. Instead, use a piece
of paper or cardboard. Escaping fluid under pressure can be invisible and can
penetrate the skin and cause serious injury. If any fluid is injected into your
skin, see a doctor at once. Injected fluid must be surgically removed by a
doctor or gangrene may result.

Auxiliary Hydraulic Controls
Auxiliary hydraulics are used with attachments that have a mechanism requiring
its own hydraulic power.
Important: Always be sure the auxiliary hydraulic control is in neutral before
starting the loader or disconnecting the auxiliary hydraulic couplers.
Standard-Flow Auxiliary Hydraulic Control
Loaders are shipped from the factory with
a standard-flow auxiliary hydraulic system
with flat-face couplers. The couplers are
located under the lift arm on the left side.
Note: A second set of hydraulic couplers
can be added to the front of the lift arm by
ordering a field installation kit.
T-Bar, Dual Hand and T-Bar/Joystick
Control Loaders: A foot pedal is used to
control the direction of oil flow. A latch is Figure 16 T-Bar, Dual Hand &
provided to lock the foot pedal for contin- T-Bar/Joystick Auxiliary
uous operation (Figure 16). Hydraulic Control
T-Bar/Joystick Control Loaders equipped
with Electric Auxiliary: The yellow button
located on the joystick controls the direction
of the flow. The farther the switch is moved
from the center, the faster the flow in the
auxiliary circuit. The direction of the flow is
reversed when the switch is moved in the
opposite direction from the center. For con-
tinuous operation, move the switch fully in
either direction and press the red button,
located on the front of the grip, and release.
To cancel continuous operation, press the
red button or move the yellow switch in Figure 17 T-Bar/Joystick
either direction. Electric Auxiliary Control
Hand/Foot Control Loaders: The right
handle controls the direction of oil flow. A
locking pin locks it in the up position for
continuous operation (Figure 18).

Observe all local regulations governing the loading and transporting of equip-
ment (Reference U.S. Federal Motor Carrier Safety Regulations, Section 392.9).
Ensure that the hauling vehicle meets all safety requirements before loading the
skid-steer loader.
1. Place blocks at the front and rear of
the hauling vehicle’s tires.
2. If the loader has an attachment, lift it
slightly off the ground.
3. Back the loader slowly and carefully
up the ramp onto the vehicle.
4. Lower the loader attachment to the
vehicle deck, turn off the engine and
remove the key.

Drive Chains
Drive chains are located in the chaincase on each side of the machine. Refer to
the Maintenance Interval Chart (page 77) for tension check interval.
Checking Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 50).
2. Rotate each tire by hand. The proper amount of chain defection should be 1/8 in.
to 1 in. (3 to 25 mm) forward and rearward. If the chain defection is more than
1 in. (25 mm) or less than 1/8 in. (3 mm) in either direction, the chains should be
adjusted.
Adjusting Chain Tension
1. Raise the loader following the Loader Raising Procedure (page 50).
2. Remove the tire from the axle to be adjusted.
3. Loosen (but DO NOT remove) the bolts holding the axle to the chaincase.
4. Front Chain Tension – To tighten the front chain, move the front axle
assembly toward the front of the loader. To loosen the chain, move the front
axle assembly toward the rear of the loader.
Rear Chain Tension – To tighten the rear chain, move the rear axle assem-
bly rearward. To loosen the chain, move the rear axle assembly toward the
front of the loader.
5. After proper tension is achieved, retighten the bolts.
Important: Be careful not to over-tighten the drive chains. Over-tightening will
cause premature drive chain and axle sprocket wear.
6. Reinstall the tire.
7. Repeat Steps 2 through 6 for any other axle requiring adjustment.
8. Lower the loader following the Loader Lowering Procedure (page 51).
Engine Air Cleaner
Important: Failure to follow proper filter servicing instructions could result in
catastrophic engine damage.
The air cleaner assembly consists of an outer (primary) filter element and an
inner (secondary) filter element. An air filter restriction indicator for monitoring
the condition of the elements is located on the front of the air cleaner. If the air
filter becomes restricted, this indicator turns red to warn the operator that the air
cleaner requires service. Push the reset button located at the end of the indicator
after fitting a clean element. For replacement elements, refer to the Replacement
Parts chart (page 50).
Note: Before replacing the filter element(s), push the reset button on the indi-
cator. Start the engine and adjust the throttle to full speed. If the indicator does
not turn red, do not replace the element(s).

CHAPTER 7
MAINTENANCE
This Maintenance Interval Chart was developed to match the Service chapter of
this manual. Detailed information on each service procedure may be found in the
Service chapter. A Maintenance Log follows the chart for recording the mainte-
nance performed. Recording the 10-hour (or daily) service intervals would be
impractical and is therefore not recommended.
Important: Under severe operating conditions, more frequent service than the
recommended intervals may be required. You must decide, based on your use, if
your operation requires more frequent service.
