SAFETY INFORMATION
OM 0467QH-A [5]
Children
Tragic accidents can occur if the operator is
not alert to the presence of children. Children
are generally attracted to machines and the
work being done. Never assume children will
remain where you last saw them
1. Keep children out of the operating area and
under the watchful eye of another
responsible adult.
2. Be alert and turn machine off if children
enter the work area.
3. Before and when backing, look behind for
small children.
4. Never carry children while operating the
machine. They may fall off and be seriously
injured or interfere with the safe operation of
the machine.
5. Never allow children to play on the machine
or attachment even when the machine is
turned off.
6. Never allow children to operate the machine
even under adult supervision.
7. Use extra care when approaching blind
corners, shrubs, trees, or other obstructions
that might hide children from sight.
Before Operation
1. Read and understand both the machine
AND implement operator's manual before
using the equipment. Know how to operate
all controls and how to stop the unit and
disengage the controls quickly. Lack of
knowledge can lead to accidents.
2. Park the machine/implement on level
ground, set the parking brake, lower the
implement to the ground, place all control
levers in neutral, shut off the engine and
remove the ignition key and allow the
rotating parts to stop BEFORE making any
implement adjustments, repairs or
inspections.
3. Keep clear of all rotating parts. Do not put
hands or feet under, or into equipment and
subframe with engine running.
4. For your safety, do not work under any hydraulically
supported machine elements, they may creep
down, suddenly drop or be accidentally lowered. Do
not use loader, quick hitch, or an implement as a
jack for servicing.
5. Do not operate the machine/implement that is
defective or has missing parts. Make sure that all
recommended maintenance procedures are
completed before operating the unit.
6. Keep the machine/implement clean. Snow, dirt or
ice build-up can lead to malfunction or personal
injury from thawing and refreezing in garage.
Inspect and clean every rotating parts.
7. Do not modify or alter this implement or any of its
components, or any implement function without
first consulting your dealer. The manufacturer will
not claim responsibility for fitment of unapproved
parts and/or accessories and any damages as a
result of their use.
8. Verify that all machine/implement safety protective
devices are in place. Shields, guards and covers
must be correctly installed at all times. When
necessary to remove these for servicing, cleaning,
or repair work, they must be reinstalled
immediately.
9. Always make sure all implement components are
properly installed and securely fastened.
10. Check that all machine/implement drivelines are in
good working order.
11. Check for moving parts excessive wear regularly.
ALWAYS USE GENUINE PARTS WHEN
REPLACEMENT PARTS ARE REQUIRED.
12. Prior to operation, clear work area and mark all
curbs, pipes, etc. that cannot be moved.
13. Inspect the machine/implement after striking any
foreign object to assure that all machine/implement
parts are safe and secure and not damaged.
14. Handle fuel with care, as it is highly flammable.
Use approved fuel container.
15. Never add fuel to a running engine or a hot
engine.
16. Fill fuel tank outdoors with extreme care. Never fill
fuel tank indoors. Replace fuel cap securely and
wipe up spilled fuel. Always refuel using properly
grounded system.

SAFETY INFORMATION
OM 0467QH-A [6]
17. Check all machine controls regularly and
adjust where necessary. Make sure that the
brakes are evenly adjusted. Periodically
check all nuts and bolts for tightness,
especially wheel hub and rim nuts.
18. Make sure the machine is counterweighted
and has tire chains for better traction and
stability as recommended by your dealer.
Weights provide the necessary balance to
improve stability, traction and steering. Use
only those recommended by your dealer.
19. Prolonged exposure to loud noise can cause
impairment or loss of hearing. Wear a
suitable hearing protective device such as
earmuffs or earplugs to protect against
objectionable or uncomfortable noises.
During Operation
1. Never allow anyone to operate the machine
and implement until they have read the
manuals completely and are thoroughly
familiar with their basic operation. Lack of
operating knowledge can lead to accidents.
2. Do not allow anyone to ride on the
machine/implement at any time. The only
one allowed is the operator that MUST sit in
the driver seat.
3. Never allow anyone near the work area. The
debris that can be thrown could cause
serious personal injuries.
4. Never stand alongside of the implement
while the engine is running.
5. Never operate the implement without safety
protective devices in place. All
machine/implement shields, guards and
covers must be correctly installed at all
times.
6. Keep clear of all rotating parts. Do not put
hands or feet under, or into the implement
with engine running.
7. If the implement starts to vibrate abnormally,
disengage the PTO, stop the engine
immediately and check for cause. Excessive
vibration is generally a sign of trouble.
8. Park the machine/implement on level ground,
place the transmission in neutral, set the
parking brake, disengage the driving system,
lower the equipment to the ground, place all
levers including auxiliary control levers in
neutral, shut off the engine and remove the
ignition key BEFORE LEAVING THE
MACHINE.
9. Always drive the machine at speeds compatible
with safety, especially when operating over
rough ground, crossing ditches, slippery surface
or when turning.
10. Operate only with good visibility and during
daylight hours, or when the area is well lit with
bright artificial light.
11. Do not run the engine indoors except when
starting engine and transporting attachment in
or out of building. Carbon monoxide gas is
colorless, odorless and deadly.
12. Exercise extreme caution when operating on or
crossing a gravel drive, walks, or roads. Stay
alert for hidden hazards or traffic.
13. Use extra caution when backing up.
14. Operate up and down (not across) intermediate
slopes. Avoid sudden starts and stops.
15. Drive machine backwards up steeper slopes
with the implement off. Then operate as you
travel down the slope.
16. Never park the machine on a steep slope. Do
not attempt to operate on steep slopes. If
operating on slopes is necessary, exercise
extreme caution when changing direction.
17. Disengage power to implement when
transporting or when not in use.
