• Wear protective gear for face, hands, feet, and body
when operating the loader.
• Allow machine to cool before repairing or maintaining
working components.
• DO NOT remove radiator cap, drain plugs, service
grease ttings or pressure taps while engine is hot.
Add coolant to the radiator and perform other services
only when the engine is stopped and fully cooled.
Hydraulic Systems Precautions
• Ensure all components are in good working condition.
Replace any worn, cut, abraded, attened or crimped
hoses and metal lines.
• DO NOT attempt makeshift repairs using tape, clamps
or cements. The hydraulic system operates under
extremely high pressure and such repairs could
cause serious injury.
Refueling Precautions
• When refueling, keep the hose nozzle or funnel in
contact with the metal on the fuel tank to avoid the
possibility of an electrical spark lighting the fuel.
Maintain control of ller nozzle.
DO NOT overll the fuel tank as
overow creates a re hazard when spilled on hot
components.
DO NOT smoke when refueling.
NEVER refuel when the engine is running. Fuel is
highly ammable and should be handled with care.
Death or serious injury can occur due to explosion
and/or re.
• DO NOT ll tank to capacity. Allow room for expansion
to reduce the risk of fuel expanding and spilling from
the tank.
• Tighten fuel cap securely. Should fuel cap be lost,
replace it with an original manufacturer’s approved
cap. Pressurization of the tank may result from using
an incorrect fuel cap.
• Prevent res by keeping the machine clean of
accumulated debris, grease and spilled fuel.
• Use ultra-low sulfur diesel fuel (ULSD) only.
• Wear proper hand and eye protection when checking
for a high pressure leak.
Hydraulic oil under pressure can
cause serious personal injury. Check for oil leaks
with a piece of cardboard. Do not expose hands to
possible high-pressure oil. Turn off engine before
attempting to tighten oil lines and ttings.
• Escaping pressurized hydraulic uid has force
sufcient to penetrate the skin and cause serious
personal injury. Ensure pressure is relieved before
disconnecting lines, hoses or valves.
• If injury from concentrated high pressure steam
or hydraulic uid occurs, seek medical attention
immediately. Injuries resulting from hydraulic uid
penetrating the skin’s surface can result in serious
infections or toxic reactions.
Battery Precautions
• Keep all sparks and ames away from batteries, as
gas given off by electrolytes is explosive.
• Acid propelled by an explosion can cause blindness
if it comes in contact with eyes. Always wear safety
glasses when working near batteries.
• If you come into contact with battery electrolyte
solution, wash off immediately. Chemicals can cause
burns.
• Always disconnect the battery ground cable before
working on the electrical system to avoid injury from
spark or short circuit.
• To avoid electrolyte loss, DO NOT tip batteries more
than 45 degrees.
• Use jumper cables ONLY in recommended manner.
Improper use can result in battery explosion or
unexpected machine motion.

Tire Precautions
DO NOT mount or demount tires
without proper training. A violent explosion can
occur.
Follow all procedures and safety instructions. Wall
charts containing mounting and demounting instructions
for all rims are available through the United States
Department of Transportation (DOT), Washington, D.C.
When in doubt, contact a qualied
tire dealer or repair service to perform required tire
maintenance.
Inspection
• Clean rims and repaint to stop detrimental effects of
corrosion and facilitate checking and tire mounting.
• Be very careful to clean all dirt and rust from rims.
This is important for securing rims into the proper
position.
• Check rim components periodically for cracks.
Replace all cracked, badly worn, severely rusted, and
otherwise damaged components with new parts of the
same size and type. If you are not sure about proper
mating of tire and wheel parts, consult a wheel and rim
expert.
DO NOT attempt to rework, weld,
heat or braze any rim components that are cracked,
broken or damaged. Replace damaged components
with new parts of the same size and type. Mixing
parts of one type with those of another is potentially
dangerous.
DO NOT reinate a at tire without
rst inspecting the tire, tube, ap, rim, and wheel
assembly for damage. Be sure parts are secured
before ination.
Starting and Stopping
Precautions
• Check all around loader to make sure there are no
people working on the machine or in the path of the
machine before starting. DO NOT start until area is
clear. Death or serious injury can occur to bystanders
from being crushed under a moving machine.
Check brakes, steering and other
control devices in accordance with instructions
before starting. Be sure parking brake is applied and
the direction control lever is in neutral.
• Latch seat belt (if equipped) and adjust to t snugly.
• Only start and operate the machine from the
operator’s seat. DO NOT bypass the neutral-start
system. If the system malfunctions, it must be
repaired.
DO NOT operate the engine in an
enclosed area without proper ventillation. Exhaust
gasses are odorless and deadly.
Parking Precautions
• Park the machine on level ground whenever possible.
On grades, park with wheels securely blocked.
Always apply parking brake.
• Before leaving operator’s station:
1. Place Forward/Reverse lever in neutral.
2. Turn off all accessories.
3. Set parking brake.
4. Shut off engine.
• Always remove ignition key when leaving the loader
parked or unattended.

3000C Force Feed Loader 1-11
OPERATING PRECAUTIONS
• Always comply with local regulations regarding
moving equipment on public roads and highways.
• Know and use the hand signals required for a
particular job. Know who has the responsibility for
signaling.
• Make sure all lights and reectors comply with state
and local regulations. Keep them clean and in good
working order so they can be seen clearly by all trafc.
DO NOT stand between the equipment
and the truck while the truck is being coupled
with the force feed loader. Death or serious injury
can result from being crushed between the two
machines. DO NOT ride on attachments.
Some work situations require
more attention to stopping distances, particularly
when going downhill. The larger the force feed
loader, the more it will slide on a slippery surface.
Steeper grades require longer stopping distances.
Familiarize yourself with these variables so you
can anticipate when longer stopping distances are
required.
• Check all gauges and warning instruments for proper
operation. If malfunctions are found, shut down the
machine and report the problem. If the failure causes
loss of steering control, loss of brake control or loss
of engine power, stop machine motion as quickly as
possible. Apply parking brake and keep the machine
securely parked until the failure is corrected or the
machine can be safely towed.
• DO NOT operate unit when warning buzzer/light is
illuminated.
• Drive the machine with care. Make sure speed is
compatible with conditions. Use caution on rough
ground, slopes and while turning.
• Be alert for hazards and obstructions such as ditches,
trees, cliffs, overhead power lines, and areas where
there is danger of a slide.
• Be aware and understand the job site trafc ow
patterns.
• Obey agmen, road signs and signals.
• Watch for bystanders. Never allow anyone to be
under the machine during operation. Never allow
anyone to reach into the machine during use.
• Operator must know how to use signaling devices
when roading the machine. Operator must also
understand which circumstances require use of each
signal. Use tail lights, slow moving vehicle signs, and
warning beacon as needed when traveling on public
roads.
• When required, provide an escort for roading.
• DO NOT tow the machine, except to remove from road
or to load on trailer.
MAINTENANCE PRECAUTIONS
• DO NOT attempt repairs unless trained to do so.
Refer to manuals and experienced repair personnel
for help.
• Before conducting maintenance, securely block the
machine and any components that may fall. Block
any working components to prevent unexpected
movement while repairs are being made.
• Always wear safety glasses and other required safety
equipment when servicing or making repairs.
• Disconnect battery before working on the electrical
system.
• Avoid lubrication or mechanical adjustments while the
machine is in motion or while engine is operating. If
lubrication or mechanical adjustment is necessary:
1. Place Forward/Reverse control in neutral.
2. Apply parking brake.
3. Shut off engine.
4. Place equipment in a safe position.
5. Securely block wheels.
6. Use extreme caution.
• Never make repairs on pressurized components such
as uid lines, the gas system or mechanical items until
the pressure has been relieved.
• Keep brake and steering systems in good operating
condition.

Determining Proper Torque
LA
L
E
LA
LH
The only reliable method of creating a consistently
leak-free and long-lasting connection is to ensure the
coupling is brought to the proper torque. Using a torque
wrench with crowfoot is the best method, but the ats
method can be used if a torque wrench is not available.
The most straightforward method of determining the
correct torque setting is to multiply the desired torque
by the length of the wrench from the center of the handle
to the center of the drive (L); divided by the length of the
wrench from the center of the handle to the crowfoot
center (LA) as shown below:
L
Figure 4-4. Torque Wrench - Crowfoot
Information and Specications
2
The minimum torque values are
adequate for sealing most applications. Maximum
torque values should never be exceeded.
There are several methods of determining the correct
setting on the torque wrench when using a crowfoot. All
of the methods involve making the setting proportional
to the effective change in length of the wrench multiplied
by the desired nal torque. The equations and
illustration below describe proper measurements. (Use
LEGEND under Figure 2-4)
Equations
• Torque setting if the crowfoot is placed in line with
respect to the wrench:
• Torque setting if the crowfoot is placed at 90° with
respect to the wrench
TS = TD * L / LA
OR
TS = TD * L / (L+E)
TS = TD * L / LH
OR
Figure 4-5. Measurements Needed
LEGEND
L = Distance from center of torque wrench handle to the
center of socket drive
E = Distance from center of socket drive to the center of
crowfoot
LA = Distance from center of torque wrench handle to
the center of crowfoot
LH = Distance from center of torque wrench handle to
the center of crowfoot, when mounted at 90°
TD = Desired torque at the tting
TS = Torque setting indicated on wrench
TS = TD * L / √(L2 + E2)
• To estimate the crowfoot size (E)
E = Drive Size * 0.5 + Distance between Drive and
Open End + Wrench Size * 0.5774

Coupling Installation
Use the following steps for proper coupling installation:
1. Determine the correct torque value for your
coupling.
NOTE: Only use the torque values specied from
the manufacturer. DO NOT use SAE torque
recommendations.
2. Ensure the seal face and threads are clean and in
good condition. O-Rings should be lubricated with
light oil, but threads should be completely dry unless
making pipe thread connections (interference seal).
NOTE: Attach the male end of the hose onto the
equipment rst since it may be necessary to
rotate the entire hose assembly to tighten the
male threads. Then route the hose into position
while avoiding twisting the hose.
3. Tighten the connection (by hand), bringing the seal
face into contact and rotating the nut until it stops.
4. Mark a line across the coupling nut and backup hex
for the ats method verication of coupling torque
(Figure 2-512).
5. Apply a wrench to the backup hex to prevent the
coupling and hose from moving while tightening the
nut with a torque wrench.
Failure to retain the backup hex during
installation will also result in additional clamp load
force that could cause damage to the seal face.
NOTE: The coupling nut must be in motion for an
accurate torque reading. If the nut is stopped
before nal torque value is achieved, it must be
loosened and retightened until the torque is
attained while the nut is in motion.
If a torque wrench cannot t into the coupling area or if
it is unavailable, the ats method may be used to ensure
that the coupling is properly tightened, as shown in
Figure 2-55:
Example 2 Flats
difference
Figure 4-6. Flats Method Tightening
NOTE: The mark placed on the nut and backup hex
after tightening by hand should rotate during nal
tightening according to the table below. (Figure
2-12) The nut and backup hex can then be
marked to indicate if the coupling loosens over
time.
