SAFETY – YOU CAN LIVE WITH IT
EQUIPMENT SAFETY GUIDELINES
Safety of the operator is one of the main concerns in designing a new piece of
equipment. Designers and manufacturers build in as many safety features as possible.
However, every year many accidents occur which could have been avoided by a few
seconds of thought and a more careful approach to handling equipment. You, the
operator, can avoid personal injury. Study the following precautions and insist those
working with you, or for you, follow them.
In order to provide a better view, certain photographs or illustrations in this manual may
show an assembly with a safety shield removed. However, equipment should never be
operated in this condition. Keep all shields in place. If shield removal becomes
necessary for repairs, replace the shield prior to use.
Replace any CAUTION, WARNING, DANGER or instruction safety decal that is not
readable or is missing. Location of such decals is indicated in this manual.
Do not attempt to operate this equipment under the influence of drugs or alcohol.
Review the safety instructions with all users annually.
This equipment is dangerous to children and persons unfamiliar with its operation. The
operator should be a responsible adult familiar with machinery and trained in this
equipment’s operations. Do not allow persons to operate or assemble this unit until
they have read this manual and have developed a thorough understanding of the safety
precautions and of how it works.
To prevent injury or death, use a tractor or skid-steer equipped with a Roll Over
Protective System (ROPS)/(FOPS) If cutting limbs overhead. Do not paint over,
remove or deface any safety signs or warning decals on your equipment. Observe all
safety signs and practice the instructions on them.
Never exceed the limits of a piece of machinery. If its ability to do a job, or to do so
safely, is in questions, DON’T TRY IT.

. Do not wear loose-fitting clothing, which may catch in moving parts.
. Always wear protective clothing and substantial shoes.
.It is recommended that suitable protective hearing and (eye protection)
sight protectors are worn.
.Keep bolts tightened to specified torque.
.Assure that all tires are inflated evenly.
.Give the unit a visual inspection for any loose bolts, worn parts or cracked
welds, and make the necessary repairs. Follow the maintenance safety
instructions included in this manual.
.Be sure that there are no tools lying on or in the equipment.
.Do not use the unit until you are sure that the area is clear, especially
children and animals.
.Because it is possible that this equipment may be used in dry areas or
in the presence of combustibles, special precautions should be taken to
prevent fires and fire-fighting equipment should be readily available.
.Don’t hurry the learning process or take the unit for granted. Ease into it
and become familiar with your new equipment.
.Practice operation of your equipment and its attachments. Completely
familiarize yourself with your new equipment.
.Use a tractor equipped with a Roll Over Protective System (ROPS) or(FOPS) if
cutting limbs overhead and fasten your seat belt before starting the engine.
.The manufacturer does not recommend usage of tractor with ROPS removed.
.Move tractor wheels/tracks to the widest recommended settings to increase stability.

11
DURING OPERATION
.Beware of bystanders, particularly children! Always look around to make sure
that it is safe to start the engine or move the unit. This is particularly important with
higher noise levels and quiet cabs, as you may not hear people shouting.
.NO PASSENGERS ALLOWED – Do not carry passengers anywhere on, or
in the tractor or equipment except as required for operation.
.Keep hands and clothing clear of moving parts.
.Do not clean, lubricate or adjust your equipment while it is moving.
.When halting operation, even periodically, set the tractor brakes, shut off
the engine and remove the ignition key.
-DO NOT operate near the edge of drop-offs or banks.
-DO NOT operate on steep slops as overturn may result.
-Operate up and down (not across) intermediate slopes. Avoid sudden
Starts and stops.
.Pick the most level possible route when transporting across fields. KEEP
UNIT IN LOWERED POSITION WHEN TRANSPORTING. Avoid the edges
of ditches or gullies and steep hillsides.
.Be extra careful when working on inclines.
.Periodically clear the equipment of brush, twigs or other materials to prevent
buildup of dry combustible materials.
.Maneuver the tractor at safe speeds.
. AVOID OVERHEAD WIRES OR OTHER OBSTACLES. CONTACT WITH
OVERHEAD LINES COULD CAUSE SERIOUS INJURY OR DEATH.
.Avoid loose fill, rocks and holes; they can be dangerous for equipment operation or
movement
. Allow for unit length when making turns.
. DO NOT WALK OR WORK UNDER RAISED COMPONENTS OR ATTACHMENTS
UNLESS SECURELY POSTIONED AND BLOCKED.
. Keep all bystanders, pets and livestock clear of the work area.
. Operate the tractor from the operator’s seat only.

12
DURING OPERATION CONT.
. Never stand alongside of unit with engine running or attempt to start engine and/or
operate machine while standing alongside of unit.
. Never leave running equipment unattended.
. As a precaution, always recheck the equipment after each days operation. Correct
all problems. Follow the maintenance safety procedures.
. Avoid operating the equipment on excessively steep hills and especially on hills that
are steeper than 15 degrees. Avoid crossing slopes if possible and do not make
sharp uphill steering corrections or a rollover could result. If your tractor starts to tip
over on a slope, turn the front wheels quickly downhill to regain stability and control.
The best way to climb most hills is to drive straight up while maintaining a steady
ground speed and constant engine RPM. The best way to descend most hills is
straight down while using steady pressure on the brakes without locking them up.
Locking the brakes in a steep downhill situation can result in loss of traction, steering
and control. When you must cross a slope on soft terrain, keep the front wheels
turned slightly uphill and maintain a constant speed and a straight line of travel.
Driving too fast, being inattentive and turning too sharply on slippery surfaces can
result in rollovers and accidents almost quicker than any other ground condition we
known of. Snow cover, wet surfaces, loose gravel and frozen ground can all
contribute to this dangerous condition. In these conditions maintain a sharp focus on
what you are doing and the terrain you are on. Do not make sharp turns and avoid
the need for hard braking if at all possible. If you start to skid or slid in a turn, turn
the front wheels in the direction of the skid to regain control.
FOLLOWING OPERATION
. Following operation, or when detaching, stop the tractor, set the brakes. Disengage
the PTO and all power drives, shut off the engine and remove the ignition keys.
. Store the unit in an area away from human activity.
.Do not store equipment where it will be exposed to livestock for long periods of time.
Damage and livestock injury could result.
. Do not permit children to play on or around the stored unit.
. Make sure all parked machines are on a hard level surface.

13
HIGHWAY AND TRANSPORT OPERATION
. Adopt safe driving practices.
-Keep the brake pedals latched together at all times. NEVER USE
INDEPENDENT BRAKING AS LOSS OF CONTROL AND/OR UPSET OF UNIT
CAN RESULT.
-Always drive at a safe speed relative to local conditions and ensure that your
speed is low enough for an emergency stop to be safe and secure. Keep speed
to a minimum.
-Reduce speed prior to turns to avoid the risk of overturning.
-Avoid sudden uphill turns on steep slops.
-Always keep the tractor in gear to provide engine braking when going
downhill. Do not coast.
-Do not drink and drive.
.Comply with state and local laws governing highway safety and movement
of farm machinery on public roads.
.Use approved accessory lighting flags and necessary warning devices to
protect operators of other vehicles on the highway during the daylight and
nighttime transport.
.The use of flashing amber lights is acceptable in most localities. However,
some localities prohibit their use. Local laws should be checked for all
highway lighting and marking requirements.
.When driving the tractor and equipment on the road or highway under 40
kph (20 mph) at night or during the day, use flashing amber warning lights
and a slow moving vehicle (SMV) identification emblem.
.Plan your route to avoid heavy traffic.
.Be a safe and courteous driver. Always yield to oncoming traffic in all
situations, including narrow bridges, intersections, etc.
.Be observant of bridge loading ratings. Do not cross bridges rated lower
than the gross weight at which you are operating.
.Watch for obstructions overhead and to the side while transporting.
. Always operate equipment in a position to provide maximum visibility at
all times. Make allowances for increased length and weight of the equipment
when making turns, stopping the unit, etc.

14
PERFORMING MAINTENANCE
.Good maintenance is your responsibility. Poor maintenance is an invitation
for trouble.
.Make sure there is plenty of ventilation. Never operate the engine of the
tractor in a closed building. The exhaust fumes can cause asphyxiation.
.Before working on this machine, stop the tractor, set the brakes, lower
loader bucket and clipper, disengage the PTO and all power drives, shut
off engine and remove the ignition keys.
.Be certain all-moving parts on attachments have come to a complete stop before
attempting to perform maintenance.
. Always use a safety support and block the wheels. Never use a jack to
support the machine.
.Use extreme caution when making adjustments.
.Follow the torque chart in this manual when tightening bolts and nuts.
.Never use your hands to locate a hydraulic leak on attachments. Use a small
piece of cardboard or wood. Hydraulic fluid escaping under pressure can
penetrate the skin.
.Before disconnecting hydraulic lines, shut off hydraulic supply and relieve
all hydraulic pressure.
.Openings in the skin and minor cuts are susceptible to infection from hydraulic
fluid. If injured by escaping hydraulic fluid, see a doctor at once.
Gangrene can result. Without immediate medical treatment, serious
infection and reactions can occur.

15
PERFORMING MAINTENANCE CONT.
.Replace all shields and guards after servicing and before moving.
.After servicing, be sure all tools, parts and service equipment are removed.
.Do not allow grease or oil to build up on equipment.
.Never replace hex bolts with less than grade five bolts and grade eight bolts
for the large pivot bolts. Refer to bolt torque chart for head identification
marking.
.Where replacement parts are necessary for periodic maintenance and
servicing, genuine factory replacement parts must be used to restore your
equipment to original specifications. The manufacturer will not claim
responsibility for use of unapproved parts and/or accessories and other
damages as a result of their use.
.If equipment has been altered in any way from original design, the
manufacturer does not accept any liability for injury or warranty.
.A fire extinguisher and first aid kit should be kept readily accessible while
performing maintenance on this equipment.

WIRELESS REMOTE OPERATION INSTRUCTIONS
The remote control/keyfob transmitter can be mounted to your joy stick or control handle by
using the hook and loop strap provided.
A reset button is located on the side of the metal box near the top. When the button is pushed
hard and held for 3 seconds, the receiver is activated and will receive a signal from the keyfob
transmitter. The receiver will remain active until it has not received a “rotate” signal for 2
hours. After 2 hours of inactivity the receiver automatically shuts down to preserve the battery
charge. The “OFF” button marked with the “OFF” symbol (O) may be also be pressed to shut
the system off and preserve the battery. THE RESET BUTTON MUST BE PUSHED TO ACTIVATE
OR RE-ACTIVATE THE RECEIVER.
You will also find a 12v battery and a 12v battery charger inside the metal box. The battery will
need to be charged on a regular basis depending upon the amount of usage. The battery
charger is already connected to the battery so just plug the adapter into a 120v outlet to charge
the battery. When charging, the red indicator light on the charger will illuminate. When the
battery is fully charged, the green indicator light on the charger will illuminate. The charger is
automatic and may be left connected for long periods of time.
The remote control/keyfob transmitter is a momentary control. The button marked with the
rotating arrow on the keyfob transmitter must remain depressed to activate the solenoid valve
which will divert hydraulic fluid flow to the rotate function. Release the button and the
hydraulic flow diverts back to the default or cutting function.
When use of the rotate function on the HyReach tree clipper is no longer required, you may
depress the OFF button on the keyfob transmitter. This will turn off the receiver and preserve
battery charge. The reset button must be pushed hard and held for 3 seconds to “turn on” or
activate the receiver (as explained above).
HELPFUL HINT:
If you are working in a remote area and do not have access to a 120v outlet to charge the
battery you may want to consider purchasing an extra battery. A fully charged battery may last
several days without recharging, depending upon how much the remote transmitter is used.
