SAFETY GUIDELINES 7
SAFETY GUIDELINES
Remember:
“The Best Operator is a Safe Operator”
CAUTION: READ AND UNDERSTAND
THE OPERATOR’S MANUAL AND ALL
THE SAFETY DECALS BEFORE
OPERATING THE GRINDER MIXER.
REVIEW ALL SAFETY INSTRUCTIONS
WITH ALL OPERATORS ANNUALLY.
BEFORE OPERATING
Do not wear loose fitting clothing as it may catch
in moving parts.
Make sure to install and/or secure all guards,
doors and shields, including the tractor power
take-off (PTO) master shield, before starting or
operating the Grinder Mixer.
Be sure that the correct implement driveline
parts are used and that they are properly
secured.
Install the safety chain when attaching the
Grinder Mixer to the tractor.
Clear the area of bystanders, especially
children, when making repairs, adjustments or
performing maintenance on the Grinder Mixer.
Do not allow riders.
Put all tractor and machine controls in “neutral”
and disengage the PTO before starting. Follow
the starting instructions according to your tractor
Manual.
Operate the Grinder Mixer only while seated on
the tractor seat.
Make sure the unit is adequately supported with
safety blocks or safety stands when changing
tires or performing maintenance.
CAUTION: KEEP CLEAR OF MOVING
PARTS. BE SURE TO SHUT OFF THE
TRACTOR AND SET THE PARKING
BRAKE. REMOVE THE TRACTOR KEY
WHILE MAKING ANY ADJUSTMENTS.
WAIT FOR ALL MOVEMENT TO STOP
BEFORE APPROACHING THE
MACHINE.
DURING OPERATION
Keep hands, feet, hair, and clothing away from
moving parts.
Keep all guards, doors and shields in place and
in good working condition.
Keep all bystanders, especially children, away
from the grinder mixer while in operation.
Do not allow riders while the grinder mixer is in
operation.
Do not attempt to unclog, clean, or adjust the
grinder mixer while it is running.
Stay away from overhead power lines.
Electrocution can occur even without direct
contact.
Keep all hydraulic lines, fittings, and couplers
tight and free of leaks. (Refer to - Hydraulic
Safety.)
Use caution when ascending or descending on
the grinder mixer. Wet shoes or boots are
slippery.
MAINTENANCE SAFETY
Follow all operating, maintenance and safety
instructions found in this Manual.
Before servicing, adjusting, repairing or
unclogging the machine, always make sure the
tractor engine is stopped, the parking brake is
set, and all the moving parts have stopped.
Use sufficient tools, jacks, and hoists that have
the capacity for the job.
Use support blocks or safety stands when
changing tires or performing maintenance.
Follow good shop practices of keeping the
service area clean and dry and use adequate
light for the job at hand.
Before applying pressure to the hydraulic
system, make sure all lines, fittings and couplers
are tightly secured and in good condition.
Make sure all guards, doors and shields are in
place and properly secured when performing
maintenance.

8SAFETY GUIDELINES
HYDRAULIC SAFETY
Make sure components in the hydraulic system
are kept clean and in good working condition.
Relieve pressure from the hydraulic system
before servicing or disconnecting from the
tractor.
Keep all hydraulic lines, fittings, and couplers
tightly secured and free of leaks.
Replace any worn, cut, abraded, flattened or
crimpled hoses.
Do not make any temporary repairs to the
hydraulic lines, fittings or hoses using tape,
clamps, or cement. The hydraulic system
operates under extremely high pressure and
temporary repairs may fail suddenly and create
a hazardous and or dangerous situation.
Wear proper hand and eye protection when
searching for a high-pressure hydraulic leak.
Use a piece of wood or cardboard as a backstop
instead of hands to identify and isolate a leak. If
injured by a concentrated high-pressure stream
of hydraulic fluid, seek medical attention
immediately. Serious infection or toxic reaction
can develop if hydraulic fluid penetrates the
surface of the skin.
Before applying pressure to the system, make
sure all components are tight and that the
hydraulic lines, hoses, and couplings are not
damaged.
TRANSPORTATION SAFETY
Make sure the grinder mixer complies with all
local regulations regarding the transportation of
equipment on public roads and highways.
Make sure the Slow Moving Vehicle (SMV)
emblem and all lights and reflectors required by
local highway and transportation authorities are
properly in place, clean, and clearly visible to
traffic.
Do not allow riders on any machinery during
transport.
Make sure the grinder mixer is securely attached
to the tractor and install a safety chain to the
grinder mixer.
Make sure the tractor brake pedals are latched
together.
Do not exceed 20 mph (32 km/h) when
transporting the grinder mixer. Always reduce
speed on rough roads and surfaces, or when
going down inclines.
Use caution when turning and always use the
turn signals on the tractor to indicate your
turning intentions to the other traffic.
The weight of the trailed machine should
NEVER exceed the weight of the towing vehicle.
Check all clearances carefully whenever the
machine is towed.
Lower the elevator into the transport position
before transporting the harvester on the
highway.
Stay away from overhead obstructions and
power lines during transport. Electrocution can
occur even without direct contact.
STORAGE SAFETY
Store the grinder mixer in an area away from
human activity.
Do not permit children to play on or around the
stored machine at any time.
Make sure that the grinder mixer is stored in an
area with a firm and level base to prevent the
machine from tipping or sinking into the ground.
Block the wheels to prevent the machine from
rolling.
TIRE SAFETY
Have only a qualified tire dealer or tire repair
service perform tire repairs.
Do not attempt to install a tire on a wheel or rim
unless you have the proper equipment and
experience to do the job.
Follow proper procedures when installing a tire
on a wheel or rim to prevent an explosion that
could result in serious injury.
Do not substitute tires with a lesser road rating
and/or capacity for the original equipment tires.
CAUTION: FAILURE TO FOLLOW
PROPER PROCEDURES WHEN
INSTALLING A TIRE ON A WHEEL OR
RIM CAN PRODUCE AN EXPLOSION
THAT MAY RESULT IN SERIOUS
INJURY OR DEATH. DO NOT ATTEMPT
TO INSTALL A TIRE UNLESS YOU
HAVE THE PROPER EQUIPMENT AND
EXPERIENCE TO PERFORM THE JOB.
REPLACEMENT, REPAIR, AND/OR
MAINTENANCE SHOULD BE DONE BY
A QUALIFIED TIRE DEALER OR
QUALIFIED REPAIR SERVICE.
