Safety
Pressurized Air and Water
Pressurized air and/or water can cause debris and/or hot
water to be blown out. This could result in personal injury.
When pressurized air and/or pressurized water is used for
cleaning, wear protective clothing, protective shoes, and eye
protection. Eye protection includes goggles or a protective
face shield.
The maximum air pressure for cleaning purposes must be
reduced to 205 kPa (30 psi) when the nozzle is deadheaded
and the nozzle is used with an effective chip deflector and
personal protective equipment. The maximum water pressure
for cleaning purposes must be below 275kPa (40 psi).
Never use compressed air for cleaning.
Trapped Pressure
Pressure can be trapped in a hydraulic system. Releasing
trapped pressure can cause sudden machine movement
or attachment movement. Use caution if you disconnect
hydraulic lines of fittings. High pressure oil that is released
can cause a hose to whip. High pressure oil that is released
can cause oil to spray. Fluid penetration can cause serious
injury and possible death.
Fluid Penetration
Pressure can be trapped in the hydraulic circuit long after
the engine has been stopped. The pressure can cause hy-
draulic fluid or items such as pipe plugs to escape rapidly if
the pressure is not relieved correctly.
Do not remove any hydraulic components or parts until
pressure has been relieved or personal injury may occur.
Do not disassemble any hydraulic components or parts
until pressure has been relieved or personal injury may
occur. Refer to the Service Manual for any procedures that
are required to relieve the hydraulic pressure
Always use a board or cardboard when you check for a leak.
Leaking fluid that is under pressure can penetrate body
tissue. Fluid penetration can cause serious injury and
possible death. A pin hole leak can cause sever injury.
If fluid is injected into your skin you must get treatment
immediately. Seek treatment from a doctor that is familiar
with this type of injury.
Asbestos Information
Rayco recommends the use of only genuine Rayco
replacement parts. Use the following guidelines when you
handle any replacement parts that contain asbestos or when
you handle asbestos debris.
Use caution. Avoid inhaling dust that might be generated
when you handle components that contain asbestos fibers.
Inhaling this dust can be hazardous to your health.
The components that may contain asbestos fibers are brake
pads, brake bands, lining material, clutch plates, and some
gaskets. The asbestos that is used in these components
is usually bound in a resin or sealed in some way. Normal
handling is not hazardous unless airborne dust that contains
asbestos is generated.
If dust that may contain asbestos is present, there are several
guidelines that should be followed:
• Avoid brushing materials that contain asbestos.
• Avoid grinding materials that contain asbestos.
• Use a wet method in order to clean up asbestos material.
• A vacuum cleaner that is equipped with a high efficiency
particulate air filter (HEPA) can also be used.
• Use exhaust ventilation on permanent machining jobs.
• Wear an approved respirator if there is no other way
to control the dust.
• Comply with applicable rules and regulations for the
work place, In the United States, refer to Occupational
Safety and Health Administration (OSHA) requirements.
• Obey environmental regulations for the disposal of
asbestos.
• Stay away from areas that might have asbestos particles
in the air

Safety
Respiratory Protection
Rayco recommends the use of dust masks or respirators
to be worn over the nose and mouth that protect the lungs
from air-borne dust and irritants. When working in activities
such as chipping brush, stump grinding, working near old
wood or chip piles, non-toxic nuisance dusts can be harmful.
Dispose of Waste Properly
Improperly disposing of waste can threaten the environment.
Potentially harmful fluids should be disposed of according
to local regulations.
Always use leak proof containers when you drain fluids. Do
not pour waste onto the ground, down a drain, or into any
source of water.
• Tools that are suitable for collecting fluids and equipment
that is suitable for collecting fluids
• Tools that are suitable for containing fluids and equipment
that is suitable for containing fluids
Containing Fluid Spillage
Care must be taken in order to ensure the fluids are contained
during performance of inspection, maintenance, testing,
adjusting and repair of the equipment. Prepare to collect the
fluid with suitable containers before opening any compartment
or disassembling any component that contains fluids.
Obey all local regulations for the disposal of liquids.
Crushing & Cutting Prevention
Support the equipment properly before you perform any work
or maintenance beneath that equipment. Do not depend on
the hydraulic cylinders to hold up the equipment. Equipment
can fall if a control is moved, or if a hydraulic line breaks.
Do not perform any work until you have read and followed
the proper “Lock-Out / Tag-Out” procedures.
Do not work beneath the cab of the machine unless the cab
is properly supported.
Unless you are instructed otherwise, never attempt
adjustments while the machine is moving or while the engine
is running.
Never jump across the starter solenoid terminals in order to
start the engine. Unexpected machinemovement couldresult.
Whenever there are equipment control linkages, the clearance
in the linkage area will change with the movement of the
equipment or the machine. Stay clear of areas that may have
a sudden change in clearance with machine movement or
equipment movement.
Avoid contact with the rotating feed wheel, cutter wheel
and rotor.
Always shut-off the engine and wait for all moving parts,
belts, fans, rotors, drums, cutting wheels (etc.) to come to a
complete stop before opening access covers and/or guards.
Stay clear of all rotating and moving parts. A moving belt,
pulley, sprocket and chain can suddenly pull a limb into them
causing loss or severe injury.
If it is necessary to remove guards in order to perform
maintenance, always install the guards after the maintenance
is performed.
Keep objects away from moving fan blades. The fan blade
will throw or cut objects.
Do not use a kinked wire cable or a frayed wire cable. Wear
gloves when you handle wire cable.
When you strike a retainer pin with force, the retainer pin
can fly out. The loose retainer pin can injure personnel.
Make sure that the area is clear of people when you strike
a retainer pin. To avoid injury to your eyes, wear protective
glasses when you strike a retainer pin.
If equipment is unhitched from the tow vehicle for operation,
always block the wheels and support the tongue weight
with blocking to prevent unintended movement. Do not use
only the jack stand to support the tongue while in operation.
NOTICE
Dust masks and/or particulate respirators only
protect against particles (e.g., dust). They do not
protect against chemicals, gases or vapors, and are
intended only for low hazard levels.

Guards (Operator Protection)
There are different types of guards that are used to protect
the operator. The machine and the machine application
determines the type of guard that should be used.
A daily inspection of the guards is required in order to check
for structures that are bent, cracked or loose. Never operate
a machine with a damaged structure.
The operator becomes exposed to a hazardous situation if the
machine is used improperly or if poor operating techniques
are used. This situation can occur even though a machine is
equipment with an appropriate protective guard.
Other Guards (If Equipped)
Protection from flying object and/or falling objects is required
for special applications. Logging applications and demolition
applications are two examples that require special protection.
A front guard needs to be installed when a work tool that
creates flying objects is used. Mesh front guards that are
approved by Rayco or polycarbonate front guards that are
approved by Rayco are available for machines with a cab or
an open canopy. On machines that are equipped with cabs,
the windshield should also be closed. Safety glasses are
recommended when flying hazards exist for machines with
cabs and machines with open canopies.
If the work material extends above the cab, top guards and
front guards should be used.
Additional guards may be required for specific applications

Slope Operation
Machines that are operating safely in various applications
depend on these criteria: the machine model, configuration,
machine maintenance, operating speed of the machine,
conditions of the terrain, fluid levels, and tire inflation
pressures. The most important criteria are the skill and
judgment of the operator.
A well trained operator that follows the instructions in the
Operation and Maintenance Manual has the greatest impact
on stability. Operator training provides a person with the
following abilities: observation of working and environmental
conditions, feel for the machine, identification
of potential hazards, and operating the machine safely by
making appropriate decisions.
When you work on side hills and when you work on slopes,
consider the following important points:
• Speed of travel – At higher speeds, forces of inertia
tend to make the machine less stable.
• Roughness of terrain or surface – The machine may be
less stable with uneven terrain.
• Direction of travel – Avoid operation the machine across
the slope. When possible, operate the machine up
the slopes and operate the machine down the slopes.
• Place the heaviest end of the machine uphill when you
are working on an incline.
• Mounted equipment – Balance of the machine may be
impeded by the following components: equipment that
is mounted on the machine, machine configuration,
weights, and counterweights.
• Nature of surface – Ground that has been newly filled
with earth may collapse from the weight of the machine.
• Surface material – Rocks and moisture of the surface
material may drastically affect the machine’s traction and
machine’s stability. Rocky surfaces may promote side
slipping of the machine.
• Slippage due to excessive loads – This may cause
downhill tracks or downhill tires to dig into the ground,
which will increase the angle of the machine.
• Width of tracks or tires – Narrower tracks or narrower
tires further increase the digging into the ground which
causes the machine to be less stable.
• Implements attached to the machine hitch or drawbar
– This may decrease the weight on the uphill tracks.
This may also decrease the weight on the uphill tires.
The decreased weight will cause the machine to be
less stable.
• Height of machine working load. When the working loads
are in higher positions, machine stability is reduced.
• Operated equipment – Be aware of performance
features of the equipment in operation and the effects
on machine stability.
• Operating techniques – Keep all attachments or pulled
loads low to the ground for optimum stability.
• Machine systemshave limitations on slopes – Slopes can
affect the proper function and operation of the various
machine systems. These machine systems are needed
for machine control on slopes.
• Note: Safe operation on steep slopes may require special
machine maintenance. Excellent skill of the operator
and proper equipment for specific applications are
also required. Consult the Operation and Maintenance
Manual sections for the proper fluid level requirements
and intended machine use.

Pre-Transportation Checks
• Never allow inexperienced drivers to tow the machine.
• When towing, always make sure the tow vehicle ball
hitch and trailer/machine hitch coupler are the correct
matching size and style.
• Always make sure the tow vehicle and the trailer/machine
are on level ground and the wheels are chocked before
connecting or disconnecting.
• Make sure the tow vehicle is of adequate size and has
the towing capacity to safely tow the combined weight
of trailer/machine.
• Never tow a machine while it is running.
• Towing will affect handling, allow for extra stopping
distances. Refer to U-Haul’s “Safe Trailering” Driver
EducationProgram that is available at this website: http://
www.uhaul.com/guide/index.aspx?equipment=towing-
autotransport
• Make sure the towing eye is at the proper height so the
machine tows level when traveling. A proper amount of
tongue weight is required to allow the machine to tow
properly. Too little tongue weight will result in wandering,
fish-tailing, and/or axle damage.
NOTE: Usecaution when backingup. The rearof the RG74T-R
may not be visible from the towing vehicle. It is recommended
to use a spotter outside the vehicle.
• Be aware of the length of the EQUIPMENT while
turning, parking, crossing intersections, and in all driving
situations. When arriving at the work site, do not set up
the EQUIPMENT under a tree that is being pruned,
cut, or worked on.
Important Towing Information
PREVENT WHIPPING by properly loading the auto transport
trailer. Load the heaviest end (engine end)of the vehicle-in-tow
to the FRONT of the trailer. Loading heavier in the rear can
cause the tow vehicle and transport trailer “combination” to
begin WHIPPING, which is violent and uncontrollable sway.
SIDE to SIDE MOTION (SWAY) THAT BEGINS as you
reach a certain speed, will likely become WHIPPING at
higher speeds. If you notice sway beginning SLOW DOWN
IMMEDIATELY by letting off the gas pedal. Then stop to
reload the vehicle-in-tow heaviest end forward as soon as
possible, and remove any cargo from the vehicle-in-tow
(vehicle carried on trailer).
IF WHIPPING or SWAY OCCURS, DO NOT steer. DO
NOT apply your brakes and NEVER speed up. Let off the gas
pedal and hold the steering wheel in a straight-ahead position.
A “combination disturbance” is improper handling, whipping,
sway, over-steering or other deviation of the tow vehicle or
trailer from their intended path, due to one or more causes
(improper loading, steering inputs, excessive speed, cross
winds, passing vehicles, rough roads, etc). IF A
COMBINATION DISTURBANCE OCCURS, DO NOT steer
or brake. Steering or braking during a disturbance can cause
a loss of control or crash.
If a WHEEL GOES OFF THE PAVED ROADWAY, DO

RG27/35/37 Operation • Service • Maintenance
800.392.2686 19
Safety
NOT steer sharply and DO NOT brake. Let off the gas
pedal and slow down below 25 mph. Then steer gradually
back onto the roadway. Proceed with caution entering
traffic.
Loading Your Combination
NEVER load cargo inside the vehicle-in-tow or on the
trailer. Cargo inside the vehicle-in tow can cause sway or
WHIPPING.
NEVER overload your tow vehicle. Do not exceed the Gross
Vehicle Weight Rating (GVWR) and the Gross Axle Weight
Ratings (GAWR), which are posted on a label inside the
driver’s door opening.
Make sure the trailer is securely attached to the tow vehicle
hitch before loading and unloading.
Keep children and others at least 25 feet away during loading
and unloading.
Slow Down When Towing
AVOID CRASHES by slowing down. Reduce your speed
from what you would normally drive without a trailer under
similar road conditions. The maximum speed is 45 mph
when towing a trailer. Do not exceed any posted speed limit.
DRIVE DEFENSIVELY – anticipate stops, brake early, and
never follow closely.
BEFORE going downhill, slow downand shift the transmission
into a lower gear. DO NOT RIDE BRAKES on downgrades.
Slow down for curves, adverse weather, hazardous road
conditions, road construction and expressway exits.
Before Towing and on the Road
Use the checklist at the end of these instructions before
towing and while on the road.
Make sure your tow vehicle is properly equipped and
maintained. Be sure all tires are inflated properly.
ALWAYS wear your seat belt.
DO NOT drive when you are fatigued, sleepy or distracted.
Avoid driving at night.
NEVER use a cell phone when driving. If you need to use a
cell phone find a safe place to exit the roadway.
NEVER drive under the influence of alcohol or any substance
that might impair your vision, judgment, or ability to control
the vehicle.
NEVER tow without properly installed tire straps and vehicle-
in-tow security chains.
DO NOT tow the trailer unless the tongue jack is fully raised
off the ground.
NEVER allow passengers to ride on the trailer.
No open or soft-top sport utility vehicle is allowed to tow a
trailer, because in the event of a crash, these vehicles offer
less collision and ejection protection.
Your Tow Vehicle
Refer to the owner’s manual, decal instructions or an
authorized automotive dealer for any specific handling
characteristics of your tow vehicle.
Changes to your tow vehicle from how it was manufactured
can affect its abilityto tow. These changescan include different
tires, suspension changes, etc. Check your owner’s manual
or with an authorized automotive dealer to make sure any
changes to your tow vehicle are approved. DO NOT tow the
trailer if your tow vehicle has changes that are not approved.
Avoid driving on a compact spare tire any longer than
necessary. Follow the vehicle manufacturer instructions.
Maintenance and condition of your tow vehicle’s engine,
transmission, steering, suspension, front-end alignment, and
tires, may affect the vehicle’s ability to tow the auto transport
trailer. Have an authorized repair facility inspect and repair
your vehicle BEFORE towing.
To find the capabilities of the engine, transmission and axles
of your vehicle for towing, refer to the owner’s manual, or
check with an authorized dealer.
TOWING EQUIPMENT
REQUIREMENTS
Hitches must be able to tow the weight of your trailer and
your vehicle-in-tow .
When towing a trailer, all lights must be operational. Also,
your tow vehicle may require external mirrors on both sides.
Tire Pressure
Set all tires to the proper pressure. Find the recommended
COLD pressures on the tire sidewall, owner’s manual,
your vehicle’s door decal or in the trailer manual. DO NOT
put more pressure in the tire than is indicated on the tire
ALWAYS LOAD THE MACHINE WITH THE OPERATOR
CONTROLS IN THE OPERATING POSITION
OR WITH REMOTE CONTROL IF EQUIPPED.
THE CONTROLS CAN EASILY BE OPERATED
WHILE WALKING ALONG SIDE THE TRAILER
DURING LOADING. LOADING THE RG74TR WITH

Safety
Connecting Your Trailer
Lower the coupler onto the hitch-ball and follow the
instructions below to properly fasten the coupler to the hitch-
ball. Do not allow your self to become distracted. Ensure
that the coupler is properly fastened to the hitch-ball before
moving to the next step.
COUPLER- Push down on the latch and fully open the
coupling. Lower the coupler onto the hitch-ball.
Check that the ball clamp is positioned below the coupler. The
coupler should completely cover and enclose the hitch-ball.
Tighten the coupler latch down.
Move the tow vehicle forward slightly, or push rearward on
the trailer to ensure that the hitch-ball is properly seated
inside the coupler. Recheck that it is tight.
Check all connections at each stop. Make sure the hitch and
hitch-ball are securely attached to your tow vehicle and the
trailer coupler is properly connected to the hitch-ball. Use the
checklist at the end of these instructions. If you suspect or
detect something is wrong, contact the nearest Rayco Dealer.
Safety Chains
The purpose of the safety chains is to keep the trailer
connected to your tow vehicle in the unlikely event the coupler
comes off the ball or the ball comes off the hitch. Safety chains
are attached to the trailertongue and are equipped with hooks.
DO NOT tow the trailer without the safety chains securely
attached to the towing vehicle. DO NOT attempt to pull the
trailer by the safety chains alone, unless this is necessary to
get the combination off the roadway to a safe place.
The left chain crosses underneath the trailer tongue and hooks
to the right side of the tow vehicle permanent hitch, frame
or structure, or to the tow vehicle bumper brackets. Do not
attach chains to the ball or to a ball mount that is removable.
The right chain hooks to the left side in the same manner.
Crossing the chains under the tongue allows the minimum
amount of slack for turning. Control slack by hooking the
chain back to itself or by twisting the links to shorten chain.
Be sure the hooks are secured.
The chains need slack to allow your vehicle to make turns.
Make sure these chains attach securely to your tow vehicle
and do not drag on the roadway.
Emergency Brake Cable/Chain
Trailers with brakes have a third chain, called the emergency
brake chain. This chain applies the brakes automatically in
the unlikely event of a separation of the trailer from the tow
vehicle. Attach this chain as close to the vehicle center
as possible; to the tow vehicle permanent hitch, frame or
structure, or to the bumper brackets. Twist chain to take
up most of the slack and secure. Some slack is necessary
to prevent the emergency brake from activating on turns or
inclined driveways.
Photo-eye (if equipped)
• Operator must be in proximity of the photo-eye in order
to engage the cutter wheel. The cutter wheel will shut
down if operator steps away from the photo-eye.
Lighting Conditions
Make sure all tow vehicle and trailer lights function properly.
The connecting wires need slack to allow your tow vehicle
to make turns. Do not allow wires to drag on the roadway.
Loading
Load the heaviest end (engine end) of the vehicle in-tow to
the FRONT of the trailer. Failure to load facing forward may
result in sway or WHIPPING and lead to total loss of control.
DO NOT load cargo in your vehicle-in-tow or on your trailer.
Loading cargo in your vehicle-in-tow or on trailer may result
in sway or WHIPPING.
Before loading your vehicle-in-tow, make sure the trailer is
securely attached to your tow vehicle hitch. Make sure the
safety chains are properly connected. During the loading
process, keep bystanders at least 25 feet away.
Make sure that the entire width of the tires will be on the
ramps before driving on the ramps.
Approach ramps slowly, check angle of machine to insure
proper alignment with trailer, then proceed to drive up
ramps into trailer.
1. Drive the machine forward and align it with the trailer.
2. Unlock and lower the trailer ramps.
3. Drive the machine forward so that the front wheels enter
the trailer channels, and continue driving the machine up
the ramps until the rear drive wheels are on the trailer.
4. Remove the machine tie-down pin from the storage
sleeve on the trailer and insert it through the matching
holes in the machine and the trailer.
5. Raise the trailer ramps and lock them in the travel position
with the lock bars and associated retaining pins.
