2.2 CONTROL PANEL
The THOMAS Mini-Skid Loader features two
independent hydraulic systems for the Mini-Skid
Loader and attachment operation.
Each of these systems is powered by either or both
hydraulic pumps. The primary pump provides
larger oil flow, while the secondary pump produces
lower flow.
One system is dedicated to hydraulic motor driven
attachments only, while the second system controls
all other Mini-Skid Loader functions. The pumps
can be switched back and forth between the two
systems or diverted as the need arises.
For example, for normal operation, one would have
the large displacement pump operating the Mini-
Skid Loader functions. However, if one was
operating an attachment with a hydraulic motor,
one would switch the circuits so that the large
displacement pump was operating the attachment,
while the smaller pump was operating the Mini-
Skid Loader, thus allowing the operator to drive
slowly while providing maximum power to the
attachment.
All functions are controlled from the top console of
the mini-skid as shown in Fig. 2.2.

Throttle Control
The throttle control is on the right hand side of the
operator area controls (Item #1 in Fig. 2.2). When
the throttle control is set fully back the engine is at
idle speed. Moving the throttle control forward
increases the engine speed. The machine should
always be operated with the throttle fully open.
Before shutting off the engine, return the throttle
control to the idle position and allow the engine to
cool for at least 2 minutes.
Steering Controls
The THOMAS Mini-Skid Loader features single-
hand steering. For normal
operation, the most
comfortable hand position is
to operate the steering levers
with the palm of the left
hand, with the fingers
gripping the grip handle.
This position will allow for
better control of the unit. At
the same time, the right hand
should grip the grip handle
for operator stability, but can
also be used to operate the
lift and tilt joystick as
required.
Flexing the fingers will allow
forward travel, and simply
rotating the palm will allow
normal steering.

Steering Controls (continued)
To reverse, slip the palm back to the rear of the grip
handle, and use the tips of the fingers to pull the
steering levers backwards.
The Mini-Skid Loader is turned by moving one
lever further forward than the other. To turn right,
move the LH Drive Lever further than the RH Drive
Lever. To turn left, move the RH Drive lever further
than the LH Drive Lever.
For the Mini-Skid Loader to turn or “skid steer”
within its own length, one lever is moved forward
and the other back. This causes the tracks on one
side to turn forward and the tracks on the other side
to reverse.
2. CONTROLS
Do not move any of the
control levers unless
standing with both feet
on the platform and
gripping the grip handle.
WARNING
Keep BOTH HANDS
on the grip handle at
all times when
operating the machine.
WARNING
Lift and Tilt Joystick
The Joystick located on the right hand side controls
the lift and tilt. Pushing the joystick forward lowers
the lift arm and pulling the joystick back raises the
lift arm. In these two positions, the joystick is spring
centered to neutral upon release of the joystick.
Moving the joystick left tilts the attachment back.
Moving the joystick to the right tilts the attachment
ahead. The joystick is spring centered to neutral
upon release.
Auxiliary Control Lever-Cylinder Operation
The THOMAS Mini-Skid Loader features two
separate auxiliary systems. The auxiliary lever
(Shown as item #4 in Fig. 2.2) is part of the primary
controls, and is located between the main levers.
This control is connected to the pair of quick
connect couplings located on the right side of the
Mini-Skid Loader arms. Pushing this lever forward
extends the attachment hydraulic cylinder, while
pulling it back reverses the motion.
This lever is mainly intended to operate attachment
hydraulic cylinders. This would include such
attachments as angling dozer blades, grapple forks,
and 4 in 1 bucket, which must operate from this
control only.
Ensure that the auxiliary
levers are kept in neutral
when not being used to avoid
wasting power. Hydraulic oil
may also overheat.
IMPORTANT
SECONDARY CONTROLS:
Pump Selector Switch
The Pump Selector Switch is located on the left hand
side of the dash panel (See Fig. 2.2A). This switch
selects which pump is connected to the primary and
the secondary circuits. This is a rotary electrical
switch which is lit green when the hydraulic system
is active, and is labeled A for left and B for right.
When the rotary knob is turned to the left (A), the
smaller secondary pump is connected to the Mini-
Skid Loader drive and the larger primary pump is
connected to the auxiliary circuit.
This would be the position used when operating
attachments such as trenchers, sweepers, roto-tillers,
snowblowers, and post hole augers, as it provides for
increased flow to the attachment while allowing a
reduced flow for Mini-Skid Loader functions.
When the knob is turned to the right (B), the large
primary pump is connected to the Mini-Skid Loader
drive circuit and the smaller secondary pump is
connected to the auxiliary valve. This would be the
normal position for operations not requiring a
powered attachment.
It is advised that any new or inexperienced operators
use the A position to become familiar with operating
the Mini-Skid Loader.
Return controls to
neutral prior to
changing hydraulic
modes.

2. CONTROLS
AUXILIARY LEVER-
HYDRAULIC MOTOR DRIVES
This lever is located to the left and forward of the
operator area controls (See Fig. 2.2, page 5, item 8),
and operates the set of quick connect couplings
located on the left hand side of the Mini-Skid
Loader arms.
This is a dedicated hydraulic motor control valve, to
be used to operate such attachments as trenchers,
post hole augers, sweepers, hammers, and similar
units. Do not connect hydraulic cylinders to this
control. When this control is in the neutral position,
the auxiliary couplers are connected together, which
provides a “free-wheeling” or “slowdown” position
for hydraulic motors, preventing attachment damage
and internal pressure buildup.
Ensure that the auxiliary
lever is kept in neutral when
not being used to avoid
wasting power.
Power is greatly reduced,
and the hydraulic oil will
overheat if the lever is
engaged without an
attachment connected to it.
IMPORTANT
2.3SAFETY INTERLOCK SYSTEM
The Mini-Skid Loader is equipped with a hydraulic
safety interlock system.
When the Mini-Skid Loader is started, all hydraulic
flow is directed away from the loader controls and
into the hydraulic tank until the operator depresses
the safety interlock pushbutton (See Fig 2.3).
To direct flow to the main control valve (which
includes drive control, lift and tilt control, and
primary auxiliary control) and the second auxiliary
valve, there is an electric Safety Interlock
Pushbutton (See Fig 2.3) located on the left hand
side of the instrument panel. This switch must be
depressed momentarily to activate the hydraulic
circuits. The Mini-Skid Loader engages the Safety
Interlock System by turning the ignition key to the
off position (See Section 3.1 for proper Shutdown
procedures).
SAFETY INTERLOCK
PUSHBUTTON
Fig. 2.3
A hydraulic cylinder
connected to this line will
not hold pressure in the
neutral position and will
be free to move! This can
result in damage or
injury.
WARNING
This lever operates side to side, moving the lever to
the left provides oil flow to the female coupler,
while moving it to the right to provide oil flow to the
male coupler. Centering the lever provides a neutral,
off position.
Always use the auxiliary couplers located on the
right hand side of the Mini-Skid Loader lift arms
for hydraulic cylinder use!
PARKING BRAKE
The Mini-Skid Loader is equipped with an
electrically actuated parking brake. The brake is
automatically engaged when the key is turned to the
OFF position.
To disengage the parking brake, depress the safety
interlock pushbutton (located on the left hand side
of the dashpanel) and jogging the RH drive lever
forward and rearward slightly to ensure the brake
pin is fully disengaged.
Use extreme caution
when stopping! If the
bucket or attachment
is raised, the machine
can tip. Keep all
movements smooth. All
new operators must
work the machine in a
safe open area to
become familiar with
its operation.

2. CONTROLS
2.4 SPEED/FLOW REGULATION
The loader is equipped with a two-pump system,
which supplies hydraulic power to operate the drive
as well as all hydraulic functions. The output of the
two pumps is 8.5 gpm (32.2 l/m) and 3 gpm (11.4
l/m).
The direction and flow from these pumps can be
controlled by a pump selector switch (fig. 2.4A), a
combiner switch (Fig. 2.4A), both of which are
located on the dash, and a flow control knob (Fig.
2.4B), located on the service access panel.
Pump Selector Switch:
The pump selector switch, (Fig. 2.4A), controls
which pump, either the 3 gpm (11.4 l/m) or 8.5 gpm
(32.2 l/m), provides flow to either the motor spool
auxiliary hydraulic circuit or the res of the loader
funtions.
Combiner Switch:
The combiner switch, (Fig. 2.4A), can be used to
combine the flow of both pumps.
Flow Control Knob:
The flow control knob, (Fig. 2.4B), allows metering
the amount of oil flow between the drive system
and the motor spool auxiliary circuit.
Turning the flow control knob clockwise will divert
oil from the loaders drive system to the motor spool
auxiliary circuit slowing the loaders travel speed.
When fully turned in, approximately 1 gpm (3.8
l/m) of oil will still flow to the loaders drive system.
This is the loaders slowest travel speed setting.
When fully turned out, no oil flow is diverted to the
loaders motor spool auxiliary circuit.
The flow control knob will function in all mode
settings except A/1.
Before making any adjustments to the selector
valve, combiner valve or flow control knob,
return the steering control levers as well as all
auxiliary hydraulic controls to the neutral
position. Do not adjust these controls while the
loader is in motion or during attachment
operation.

OPERATING MODES (See Fig. 2.4C):
A/0 - Trencher Operation, New Operators
This mode is used for operating motorized
hydraulic attachments such as trenchers, sweepers,
augers, snow blowers etc. This position provides a
slow travel speed as well as reduced oil flow to the
loaders boom and bucket and the cylinder spool
auxiliary hydraulic circuit while providing
increased oil flow to the motor spool auxiliary
hydraulic circuit. With the attachment connected to
the loaders motor spool auxiliary hydraulic circuit,
set the controls as follows.
Pump Selector Switch - Set switch to "A" position.
Combiner Switch - Set the switch to "0" position.
Flow Control Knob - Turn clockwise to reduce the
loaders drive speed and increase the amount of flow
to the motor spool auxiliary circuit.
With the flow control knob turned fully out (counter
clockwise), approximately 3 gpm (11.4 l/m) flows
to the loaders drive and 8.5 gpm (32.2 l/m) flows
to the motor spool auxiliary hydraulic circuit. This
provides a travel speed of 1.3 mph (2.1 km/hr).
With the flow control knob turned fully in
(clockwise) approximately 1 gpm (3.8 l/m) flows to
the loaders drive system and 10.5 gpm (39.8 l/m)
flows to the motor spool auxiliary hydraulic circuit.
This provides a travel or "inching" speed of 0.3
mph (0.5 km/hr). NOTE: While this is the
recommended trenching mode, trenching can be
performed in any mode by using the flow control
knob to divert oil.
B/0 - Bucket Operation
This mode is used for normal bucket and travel
operation as well as for operating cylinder equipped
hydraulic attachments such as grapples. This
position provides a fast travel speed as well as
quick boom and bucket operation and a higher flow
to the loaders cylinder spool auxiliary hydraulic
circuit. Attach the hydraulic powered attachment to
the cylinder spool auxiliary hydraulic circuit or
mount a bucket or other attachment and set the
controls as follows.
Pump Selector Switch - Set switch to "B" position.
Combiner Switch - Set the switch to "0" position.
Flow Control Knob - Turn clockwise to reduce the
loaders drive speed and increase the amount of oil
flow to the motor spool auxiliary circuit.

flows to the loaders drive and cylinder spool
auxiliary hydraulic circuit. 3 gpm (11.4 l/m) flows
to the motor spool auxiliary hydraulic circuit. This
setting provides a travel speed of 3.5 mph (5.6
km/hr).
With the flow control knob turned fully in
(clockwise) approximately 1 gpm (3.8 l/m) flows to
the loaders drive system and 10.5 gpm (39.8 l/m)
flows to the motor spool auxiliary hydraulic circuit.
This provides a travel or "inching" speed of 0.3
mph (0.5 km/hr).
A/1 - Stationary Power Source
This mode is used to provide full hydraulic power
to the motor spool auxiliary hydraulic circuit to
power attachments such as water pumps where no
travel speed or boom and bucket operation is
required.
In this position the loaders travel speed, boom and
bucket circuits as well as the cylinder spool
auxiliary hydraulic circuits do not function.
Pump Selector Switch - Set switch to "A" position.
Combiner Switch - Set the switch to "1" position.
Flow Control Knob - The flow control knob does
not function in this mode.
In this mode the drive system receives 0 gpm (0
l/m) while the motor spool auxiliary hydraulic
circuit receives 11.5 gpm (43.5 l/m).
B/1 - High Speed Travel
This mode is used when long travel distances are
encountered. This position provides the fastest
maximum travel speed as well as increased oil flow
to the loaders boom and bucket and cylinder spool
auxiliary hydraulic circuit while providing reduced
oil flow to the motor spool auxiliary hydraulic
circuit. Attach the hydraulic powered attachment to
the cylinder spool auxiliary hydraulic circuit or
mount a bucket or other attachment and set the
controls as follows.
Pump Selector Switch - Set switch to "B" position.
Combiner Switch - Set the switch to "1" position.
Flow Control Knob - Turning clockwise will
reduce the loaders drive speed and increase the
amount of flow to the motor spool auxiliary circuit.
With the flow control knob turned fully out (counter
clockwise), approximately 11.5 gpm (43.5 l/m)
flows to the loaders drive and cylinder spool
auxiliary hydraulic circuit. 0 gpm (0 l/m) flows to
the motor spool auxiliary hydraulic circuit. This
setting provides a travel speed of 4.4 mph (7.1
km/hr).
With the flow control knob turned fully in
(clockwise) approximately 1 gpm (3.8 l/m) flows to
the loaders drive system and 10.5 gpm (39.8 l/m)
flows to the motor spool auxiliary hydraulic circuit.
This provides a travel or "inching" speed of 0.3
mph (0.5 km/hr).

After hook-up to
attachment, check to
be sure pins are fully
engaged, and locked
into position.
WARNING
2.5ATTACHMENT LOCK PINS
The quick-tach design allows changing from one
attachment to another quickly and easily by
disengaging pins.
Attachments are secured on the unit with two spring
loaded cam action locking pins. Rotating the
handles on the pins one half turn moves the pins
from the locked to the unlocked position.
To unlock attachments, rotate both pins so that their
handles are both pointing to the outside of the
quick-tach. (Figs. 2.5)
To lock attachments, rotate both pins inwards so
that both handles are pointing towards the center of
the machine. This will allow the springs to push the
pins downwards through the mounting holes in the
attachment and secure it to the unit. (Figs. 2.5A)

3. OPERATION
3.1STARTING INSTRUCTIONS
1. Pre-Starting Inspection
Before starting the Mini-Skid 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 lines for leaks.
(3) Check lights, battery level and cables.
(4) Inspect tracks, pivot points, mounting pins, nuts
and bolts for possible failure or looseness.
(5) Check all controls are in the neutral position.
(6) 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 4.9.
3. Shut-Off Procedure
(1) Select level ground whenever possible. If you
must park on a slope or incline, position the
machine at right angles to the slope. Lower the
attachment to the ground and block the tracks.
(2) Lower the lift arms and ground the attachment.
(3) Return auxiliary hydraulics to the neutral
position.
(4) Return the throttle control to the idle position. If
the engine is hot, allow it to idle for at least 2
minutes.
(5) Turn the ignition switch to the OFF position
and remove the key.
Do not move any of the
control levers unless
standing with both feet
on the platform and
holding the grip handles.
WARNING
2. Starting Procedure
(1) Set the throttle for idling speed. Avoid
excessive engine speed during warm-up.
(2) Turn the ignition key counter clockwise to
activate the glow plugs. Hold approximately 6
seconds.
(3) Turn the key clockwise to the 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.
(4) Allow the engine to warm up for 5 minutes
before operating. Keep the operator’s area free
of debris. Always drive the loader at speeds
compatible with safety, especially when
operating over rough ground, unfamiliar
terrain, when crossing ditches or when turning.
(5) To restart a warm engine, move throttle control
slightly ahead of idle position and turn ignition
key to “START”.
Ensure that the auxiliary
lever is kept in neutral
when not being used to
avoid power loss and
overheating of
hydraulic oil.
IMPORTANT
Do not crank engine with
starter for more than 15
seconds at a time, as this
will overheat the starter.
IMPORTANT
This engine is equipped
with glow pugs. Do not
use ether or any high
energy fuels to assist
starting.
IMPORTANT
Always let the engine
warm completely before
you begin operation each
day.
