Operating Guidelines
2040-121

Fire Prevention
Rubber track loaders have components
that operate at high temperatures. The
main heat sources are the engine and
the exhaust system. The electrical sys-
tem can also be a source of heat or
sparks if damaged or improperly main-
tained.
In some work environments, flammable
items such as leaves, straw, and brush
cutting debris may come in contact with
these components. It is very important
that flammable items be removed often
from close proximity to these high tem-
perature items. If debris is allowed to
accumulate, a fire may result posing a
risk to the operator and the machine. A
fire can cause machine damage, severe
injury, or even death.
Overheat Prevention
The radiator/oil cooler must be inspected
for signs of clogging and cleaned daily or
more often as needed to prevent the
engine and hydraulic system from over-
heating
Listed are a set of precautionary tasks
that should be performed daily or more
often if necessary. Repair or replace
worn or damaged components as
needed to ensure safe machine opera-
tion.
Precautionary Tasks
• With the engine off and cool, clean
dirt/debris from the radiator/oil cooler,
engine compartment, exhaust system,
attachments and other areas where
there may be hot or rotating parts.
Remove the belly pans and pressure
wash these items and all surrounding
areas until clean.
• Check battery, fuse panel, electrical
wiring and connections for damage or
looseness.
• Check fuel and hydraulic lines/hoses
for leaks or damage. Never use bare
hands to check for leaks. Pressurized
fluid can penetrate skin and cause
injury or even death.

1. Remove any attachment
from the machine.
2. Have an second person
remove the lift arm brace.
3. Raise the lift arms.
4. Have the second person
place the lift arm brace onto the
top side of the cylinder ram.
5. Install the retaining pins
using the holes labeled with the
arrows.
6. Slowly lower the lift arms
until they contact the brace.
7. Reverse these steps to
disengage the lift arm brace
WARNING
If instructions to safely install
lift arm brace are not followed
injury or death could result.

Operating Capacity
The operating capacity is a percentage
of the machine’s tipping load. Tipping
load refers to the amount of weight
required to tip the machine forward when
applied to the center of gravity of the
standard dirt bucket.
This rating is calculated with the machine
on level ground and the bucket attach-
ment installed, curled and raised until at
its furthest point from the machine in the
lift arm travel path.
The Rated Operating Capacity is then
calculated as 35% of the tipping load for
traditional track loaders and 50% of the
tipping load for wheeled skid steer load-
ers. ASV publishes both figures for refer-
ence and comparison.
Note: SAE J818 standards define oper-
ating capacities of rubber-tired skid
steers (50% tipping load) and tracked
loaders (35% tipping load). There are no
standards defining the operating capacity
of machines equipped with a suspended
undercarriage or machines with rubber
tracks.
Gross Vehicle Weight
The GVW (Gross Vehicle Weight) of the
PT-50 or PT-60 should not exceed 8,500
lbs. This weight does not include an
operator, but does include any acces-
sories, attachments or material being
carried. Operating the machine in excess
of the GVW will void the warranty (see
page 2).
OOPPEERRAATTIINNGGCCAAPPAACCIITTYY

Loader and Drive Controls
The PT-50 and PT-60 have two hydraulic
pilot joystick controls. The joysticks are
used to control machine speed and
direction as well as lift arm, bucket, and
attachment functions. Joystick A (photo
right) is used to control the lift arms,
bucket, and to engage the float function.
To activate the float function, move the
joystick fully forward in a quick motion.
The joystick will then be held in detent
by the magnet attached to the joystick
base. Pull back quickly to disengage.
Joystick B controls the direction and
speed of the machine.
Control Options
Machines are available with a "Case"
style control configuration. Machines
equipped in this manner use similar joy-
sticks, but operate using a different pat-
tern to control machine function. In this
pattern, joystick A controls both the right
track and the bucket curl and dump func-
tions. Joystick B controls the left track,
lift arm, and float functions. The float
function does not have a detent position
in this configuration and must be manu-
ally held in position while operating with
float engaged.
Throttle
The throttle (C) controls engine rpm.
Use a lower rpm for work that requires
delicate operation of the machine. Use
higher rpm when faster travel speed,
higher horsepower, or more flow is
required.
• To Increase RPM, move the lever (C)
toward the front of the machine.
• To decrease RPM, move the lever (C)
toward the rear of the machine.

Operation on Inclines
ASV Rubber Track Loaders are very sta-
ble on inclines. Machine weight is distrib-
uted evenly throughout the chassis and
the suspended undercarriage track sys-
tem provides excellent traction and
floatation on nearly all surfaces.
Even with these capabilities, caution
should always be exercised while oper-
ating the machine on an incline. Never
operate the PT-50/60 on an incline in
excess of 15°. Do not make sudden
changes in direction, move slowly, and
always carry loads low to maximize
machine stability.
When turning on an incline, back down
the hill while slowly turning until the
machine is pointed in the desired direc-
tion. Then proceed forward.
Manual Quick-Attach (PT-50/60)
Fastening Attachments
With both levers on the quick-attach
interface in the “up” position, drive
towards the attachment with the top
edge of the quick-attach tipped forward
(photo C). Hook the top edge of the
quick attach under the upper lip of the
attachment interface. Raise the lift arms
up slightly and then curl the quick-attach
until it is fully mated with the attachment.
Turn the engine off and exit the machine.
Secure the attachment by pushing the
levers downward (photo D).
To confirm engagement:
1. Raise the lift arms slightly.
2. Tilt the attachment downward.
3. Visually verify that the locking pins
can be seen through the bottom of
the mating interface.
Carry load low. Do not exceed rated oper-
ating capacity. Load, unload, turn on level
ground. Travel up and down hill with heavi-
est end of machine uphill. Failure to follow
instructions or heed warnings could result
in machine damage, injury or even death.

Hydraulic Quick Attach (optional)
The PT-50/60 machines are available
with a hydraulic quick attach mecha-
nism. This feature allows an operator to
fasten or unfasten attachments without
exiting the machine. To use this feature,
make sure the switch is in the unlocked
position, then follow the instructions on
page 11 that describe the process of fas-
tening the attachment to the quick attach
up to the point of locking it in place.
Once the attachment is in place, move
the switch to the lock position, then con-
firm engagement by following steps 1-3.
Bucket Positioning (optional)
The PT-50/60 machines can be
equipped with a self-leveling loader
valve (photo A). This feature is also com-
monly referred to as “bucket positioning”.
This function maintains the position of an
attachment throughout the upward cycle
of the lift arms.
Note: The bucket positioning feature
works on the upward cycle only. The
operator must position the attachment
manually on the downward cycle.
The bucket positioning feature can be
turned on or off with the switch located
on the dash panel (photo B).
The bucket positioning system does not
automatically level your attachment.
When activated, it works to keep the
attachment in the same relative position
throughout the upward cycle of the lift
arms. For example, if you have a bucket
full of dirt that is fully curled at ground
level, the bucket positioning system will
maintain the position of the bucket dur-
ing the lift cycle to prevent spilling as the
lift arms are raised.
Note: During the upward cycle, the
bucket positioning function can be over-
ridden by operating the tilt or curl func-
tions of the joystick.

Auxiliary Hydraulics
The PT-50 and PT-60 models come
equipped with an auxiliary hydraulic gear
pump. This pump has a maximum rating
of 17.44 gpm.
To operate, connect the attachment to
the two quick couplers (photo C). To
release any pressure in the system,
press the button labeled 1 in photo C.
The auxiliary hydraulics can be engaged
intermittently or continuously depending
on the requirements of the attachment
being utilized.
To engage the hydraulic flow intermit-
tently, activate the toggle-type switch on
the top of the right joystick, photo D.
Intermittent function is ideal for attach-
ments such as grapple buckets and
dozer blades.
To engage the hydraulic flow continu-
ously, activate the 3-position switch on
the dash panel, labeled 2 in photo E.
Continuous function is ideal for attach-
ments such as snow blowers, brush cut-
ters or backhoes.
Note: Moving either switch from one
position to the other has the effect of
reversing flow through the auxiliary
hydraulic circuit.
Note: The continuous flow switch must
be in its neutral position in order to start
the engine.
Note: The continuous flow auxiliary
switch has a small orange locking switch
that must be disengaged before the
switch will activate.

Electric Attachment Control
Attachments for the PT-50 and PT-60
are controlled by pressing various but-
tons on the machines joysticks. Most
attachments are controlled hydraulically,
but some require both hydraulic and
electrical inputs. The snow blower for
instance needs both hydraulic and elec-
tric input to function. The 4 buttons on
the left joystick (photo A) send electrical
current to the receptacle on the lift arms
(photo B). ASV attachments that require
electrical inputs have a matching recep-
tacle.
Note: The electrical receptacle is not
necessarily compatible with other
brands, use ASV approved attachments
for proper function.
Two Speed
The PT-60 is equipped with a two-speed
drive system. Low range is best suited to
performing strenuous work or running
attachments. High range is intended
mainly for transporting. Whenever the
machine is turned off, the lap bar is
raised, or the operator exits the seat, the
machine automatically returns to low
range. To shift between high and low
ranges, push the button (1) on the front
of the right joystick. When shifting
between ranges, slow the machine to
ensure a smooth transition. The high
range indicator (2) illuminates to confirm
high range operation.

water from the fuel supply as the engine
runs. Drain the water separator daily to
maintain proper function.
To drain the water separator:
1. Loosen the twist valve on
the bottom of the separator.
2. Retighten the valve once all of the
water has been drained from the
catch bowl.
Fuel Specifications
In North America, diesel fuel, distilled
from crude oil, that is identified as No. 1-
D or No. 2-D in “ASTM D975” generally
meet the proper specifications.

Undercarriages
The undercarriage assemblies typically
operate in harsh working conditions.
They work in mud, gravel, debris and
various other abrasive materials during
operation. ASV recommends a daily
inspection of the undercarriage assem-
blies and cleaning if necessary.
Materials that are particularly sticky or
abrasive like clay, mud, or gravel should
be cleaned from the undercarriages
often to minimize component wear. A
pressure washer works well for cleaning
materials from the undercarriages. At
times when a pressure washer is not
available, use a bar, shovel or similar
device to remove foreign materials.
When cleaning, pay particular attention
to the drive motors/sprockets and the
front and rear wheels where debris is
likely to accumulate. If working in scrap
or debris, inspect the undercarriages
more often and remove foreign objects
that may wrap around or lodge them-
selves between components causing
premature wear and damage.
Operation on sand, turf, or other finished
surfaces may require less frequent
cleaning, but daily inspection is still
advised.
Track Tension Adjustment
Proper track tension is necessary for
optimal undercarriage/track performance
and service life. Running a track that is
too loose can cause the track to mis-
feed, possibly causing damage. Running
a track that is too tight can cause track
stretch, bearing failure or other preventa-
ble damage.
During the first 50 hours of operation the
tracks will "break-in" and may require
adjustment.
To adjust the track tension:
1. Locate jam nut on track tensioner and
clean the threads thoroughly prior to
proceeding (photo C).
2. Using a wrench, loosen the jam nut on
the track tensioner.
3. After the jam nut is loosened turn the
tensioner until the track tension is
within specification listed on page 20
(photo D).
4. Turn the tensioner the opposite direc-
tion to loosen the track.
5. Once proper tension is achieved,
retighten the jam nut on the tensioner.
If the track tensioner is stiff, you may
need to use a pipe on the end of the
wrench for more leverage.
