Work Area Safety
Remember, safety is rst! Only set up to work in
areas properly protected from trac and other haz-
ards. Individuals being struck by vehicles or mobile
equipment leads to many work zone fatalities or
injuries. Work zones need trac controls identied
by signs, cones, barrels and barriers. You should
always wear high visibility clothing with a uorescent
background and made of retro-reective material
to be more visible to motorists and reduce the pos-
sibility of an accident. Work stations should always
be illuminated.
Outt all operators and support personnel with
proper safety apparel. Always use eye protection
to shield from projected debris. Use ear protection
to protect from noise levels generated from the
truck and cutter. It is very important to wear steel
toed boots that provide good traction on slippery
surfaces such as on top of the water tank or chas-
sis platforms.
Never wear loose clothing. Loose clothing can get
caught on moving or rotating parts causing serious
injury or even death.
Most rumble stripping and grinding operations gen-
erate noise levels above 90 dB. Hearing protection
is required in accordance with OSHA standards.
OSHA’s Permissible Noise Exposure
90 dB 8.0 hours
92 dB 6.0 hours
95 dB 4.0 hours
97 dB 3.0 hours
100 dB 2.0 hours
102 dB 1.5 hours
105 dB 1.0 hours
110 dB 30 minutes
115 dB 15 minutes
WARNING
ALL PERSONNEL EXPOSED TO 90 DB OR GREATER
NOISE LEVELS SHOULD RECEIVE INSTRUCTION IN THE
CORRECT USE OFEAR PROTECTIONSO THAT THEIRNOISE
EXPOSURE LIES WITHIN THE LIMITS SPECIFIED BY OSHA.
NEVER ALLOW ANYONE NEAR THE WORK AREA WITHOUT
PROPER EAR PROTECTION.
REMEMBER: GRINDING OPERATIONS CAN CAUSE DEBRIS
TO BE PROJECTED UNEXPECTEDLY IN AND AROUND THE
WORK AREA THAT CAN CAUSE SEVERE INJURY. MAKE
SURE ALL PERSONNEL STAY CLEAR OF THE GRINDING
AREA AND USE HARD HATS, EYE AND EAR PROTECTION.
Always be sure your work area is clear of people
whenever the cutter is engaged. When working
on any component of the truck or cutter chassis,
always make sure the truck is parked and in the
service position.

perform maintenance or repairs.
Cutter Hazard
Raising the lift arm and securing it with the locking
arm and latch can be hazardous and requires spe-
cial precautions that must be observed to reduce
the possibility of severe injury to personnel and
damage to equipment. Common sense and good
judgement must be used whenever the cutter is
raised and secured for transit.
The following safety precautions when op-
erating the cutter:
• All operators and support personnel should
be fully trained in the safe operation of the
grinding unit.
• As the lift arm moves up and down, pinch
points are formed. Make sure to keep hands,
feet, hair, jewelry, loose clothing, etc. away
from these pinch points. If any of these items
become caught, serious personal injury or
death could occur.
• Keep working area clear of all pedestrians
while operating the cutter. Never allow anyone
to walk, stand, or perform work near the cutter
while it is in operation.
• Align the vehicle and the cutter arm with the
road surface before engaging and lowering
the cutter.
• Always stop and raise the cutter before revers-
ing the vehicle or making sharp turns.
• After completing operations, always secure
the cutter am in the full up position with the
locking arm and pins, disengage the transmis-
sion PTO and shift the truck to TRAVEL mode.
• Never move or drive the vehicle at highway
speeds with the lift arm unsecured with the
locking arm and latch.
• If adjustments are required with the cutting
drum rotating, always make sure the safety
shroud is in place securely fastened.
DANGER
A ROTATING CUTTING DRUM CAN CAUSE SEVERE INJURY
OR DEATH IF HANDS, FEET OR LOOSE CLOTHING ARE
CAUGHT BY THE TEETH. ADDITIONALLY, LOOSE TEETH
OR DEBRIS STUCK IN TEETH CAN BE THROWN FROM THE
DRUM WITH ENOUGH FORCE TO CAUSE INJURY.
ALWAYS MAKE SURE THE SAFETY SHROUD IS PROPERLY
INSTALLED AND THE HEAD IS ON THE GROUND BEFORE
MAKINGANY ADJUSTMENTS WITH THE CUTTER ENGAGED.
NEVER ALLOW ANYONE TO STAND NEAR OR BEHIND THE
CUTTER WHILE THE DRUM IS ROTATING WITH THE SAFETY
SHROUD REMOVED.
DANGER

LIFT ARM. NEVER WEAR LOOSE CLOTHING OR JEWELRY
WHILE OPERATING THIS EQUIPMENT.
1.4 Electrical System Hazards
The electrical system on your vehicle is powered
by a high amperage 12 or 24 volt DC electrical sys-
tem. To avoid short circuits and circuit overloads
that can damage the electrical system or cause a
re, the following precautions apply:
• Turn the main circuit breakers to the OFF posi-
tion when the vehicle is unattended.
• All circuit breakers for overload protection in
electrical circuits must be kept in good condi-
tion.
• Never attempt to correct a blown fuse with a
fuse of a higher amperage. This could result
in equipment damage or an electrical re.

17
Section 1 - Safety Information
• Disconnect the negative (-) battery cable rst
and when reconnecting, connect the negative
(-) cable last.
• Do not grind, weld or have open ame near
batteries. Sparks can cause explosion.
• Do not weld on truck without turning o the
main circuit breakers and disconnecting the
batteries.
• Do not short across battery terminals. Sparks
can cause an explosion.
1.5 Hydraulic System Hazard
The hydraulic systems for the hydrostatic drive,
lift cylinders and hydraulic motors operate at ex-
tremely high pressure. Always use extreme cau-
tion when working around hydraulic systems. A
high pressure uid leak from a damaged hose or
tting can cause severe lacerations to a person’s
skin or inject hydraulic uid into the blood stream,
which can be fatal.
The following hydraulic system precautions
apply:
WARNING
TO AVOID SERIOUS INJURY OR DEATH, NEVER USE YOUR
HAND OR OTHER PART OF YOUR BODY TO CHECK FOR
LEAKS IN THE HYDRAULIC SYSTEM. USE A PIECE OF
CARDBOARD OR OTHER DEVICE TO IDENTIFYWHERE THE
HYDRAULIC SPRAY IS EMITTING.
• Hydraulic hoses and connections must be
inspected frequently to ensure they are in
good condition and that there are no signs of
chang or deterioration.
• Use only hydraulic components which are
marked with the recommended operating
pressure. Never exceed the operating pres-
sure of the weakest component in the system.
• Make sure hoses are protected from contact
with sharp objects or chang.
• Stretched or abused hose can fail prematurely
and unexpectedly, which could cause injury to
personnel. Hoses that have been exposed to
excessive stretching, kinks or chang should
be replaced.
• Always make sure all personnel maintain a
safe distance from all hydraulic components
and hoses whenever the cutting unit is in
operation.
• Always depressurize the hydraulic system
before removing any hydraulic components,
hoses or ttings. Failure to do so could result
in serious injury or death.
WARNING
INJURIES FROM HIGH PRESSURE HYDRAULIC SYSTEM
COMPONENT FAILURES ARE VERY SERIOUS AND CAN
RESULT IN SEVERE INJURY OR A FATALITY. ALWAYS
MAKE SURE ALL PERSONNEL ARE A SAFE DISTANCE
FROM HYDRAULIC SYSTEM COMPONENTS AND HOSES
WHENEVER THE VEHICLE IS OPERATING.
WARNING
ALWAYS USEEXTREME CAUTION WHEN WORKINGAROUND
HYDRAULIC SYSTEMS. A HIGH PRESSURE FLUID LEAK
FROMADAMAGED HOSE OR FITTING CAN CAUSE SEVERE
LACERATIONS TOAPERSON’S SKIN OR INJECTHYDRAULIC
FLUID INTO THE BLOOD STREAM, WHICH CAN BE FATAL.
• If the unit is operated in temperatures below
68 degrees Fahrenheit, you must always per-
form the cold weather hydraulic system warm
up procedure in this section and the Operation
chapter to avoid signicant or catastrophic
damage to the system.

Section 1 - Safety Information
1.6 Dumping Safety
Standard Debris Tank
• Always drain all the liquid from the debris
tank before dumping the solids.
• Always dump on level ground, never uneven
or sloped ground.
• Always choose solid ground, not soft sand or
wet soil.
• Always use the remote control to tilt the tank.
• Make sure the operator and all personnel are
well clear of the truck before tilting the tank.
• Never allow personnel under a raised tank
without safety supports in place.
• Always be careful to avoid any pinch points
which could cause injury.
High Dump Tank Lift Hazard
Raising the scissor lift and debris tank can be haz-
ardous and requires special precautions that must
be observed to reduce the possibility of severe
injury to personnel and damage to equipment.
Remember that raising the tank also raises the
vehicle center of gravity which can cause the truck
to become unstable or even tip over if it is not on
level ground. Common sense and good judgement
must be used whenever the debris tank is raised.
Always be alert to unforeseen problems as the
tank raises and be prepared to stop immediately
if a problem occurs.
The following safety precautions apply when-
ever operating the scissor lift:
• All operators should be trained in the safe opera-
tion of the dump system before operating the
machine or raising the debris tank.
• Always park the truck on solid, level ground be-
fore raising and dumping the debris tank. Never
attempt to dump on uneven or sloped ground.
• Always drain all the liquid from the debris
tank before raising the tank and dumping
the solids.
• Always apply vehicle park brake before operating
scissor lift to raise the tank.
• Always lower the kickstand to stabilize the truck
before raising the tank.
• Always look up and be aware of overhead clear-
ance when raising the tank.
• To avoid the possibility of electric shock, do not
raise the debris tank under or near any overhead
electrical cables or wires. Failure to follow this
warning could lead to injury or death.
• Always use the remote control to tilt the tank.
• Keep working area clear of all pedestrians when
operating scissor lift to raise the tank. Never
allow anyone to walk, stand, or perform work
near or below a raised debris tank.
• As the scissor lift mechanism moves up and
down, “pinch points” are formed. Make sure to
keep hands, feet, hair, jewelry, loose clothing,
etc. away from these pinch points. If any of these
items become caught, serious personal injury or
