18” CHIPPER SAFETY PRECAUTIONS
Before operating the chipper, read this manual, the engine manual, and all the safety decals
on the machine. Know all parts of the machine and their functions, especially the shut
down procedures in case of emergency. No inexperienced person may operate the chipper.
Inexperience may cause injury. It is the owner’s responsibility to ensure all operators are
trained and fully understand all safety and operational aspects of the chipper.
This machine was built with safety in mind. The guards and other safety devices only work
when kept in place and secured properly. Safety decals are placed on the machine as
reminders of how to operate the machine safely, pay attention to the instructions.
SAFETY FIRST ALWAYS!
This is the Safety-Alert Symbol. This symbol is placed on the machine and in
the manual to alert the operator to the potential for bodily injury or death. The
operator should pay close attention to the instructions whenever they see this
symbol.
The Safety-Alert Symbol will be accompanied by one of the following words:
DANGER, WARNING, or CAUTION
• A DANGER symbol means that if the instructions are not followed the possibility of
serious personal injury or death is probable.
• A WARNING symbol means that if the instructions are not followed there is a
possibility of serious personal injury or death.
• A CAUTION symbol means there is an unsafe condition or practice that may cause
personal injury or property damage.
PERSONAL PROTECTION:
All personnel must wear eye and
ear protection, hard hat, short
fitted gloves without cuffs, long
sleeve shirt, long pants without
cuffs, and over the ankle work
boots with skid resistant soles
Do not wear loose-fitting clothing
Tie long hair back
Do not wear jewelry or long
dangling clothing; i.e. neckties,
long belts, or chains
Stay away from feed wheels
Keep away from moving parts
Only run in a well ventilated area
because of carbon monoxide
poisoning

18” CHIPPER SAFETY PRECAUTIONS
Be Safe and Practice Safe Operation using the following guidelines.
• Any individual operating this chipper
must first read and understand this
manual, the engine and other
component manuals supplied with the
chipper, and all safety and operational
decals on machine.
• DO NOT permit children to operate
machinery or to play near machinery
during operation.
• DO NOT allow spectators to stand and
watch chipper in operation.
• DO NOT allow people to pass by
discharge zone while chipper is in
operation.
• Keep hands, feet, legs, clothing, hair
and all other body parts away from
feed intake wheels, chipper knives, and
other moving parts.
• Do not hang from, ride, sit, stand, lay,
or climb anywhere on this chipper
while it is in operation, running, or
being transported.
• Do not move, position, or transport
this chipper with the engine running.
• Keep away from pressurized leaks.
Never check for leaks using hand or
finger, use cardboard or wood.
Pressurized fluid can penetrate the skin
and cause injury or even death.
• DO NOT operate any machinery while
under the influence of alcohol or drugs
(prescription, over the counter, or
otherwise).
• DO NOT modify or change any part
without written approval from J. P.
Carlton Company.
• No one should ever reach, lean, or kick
into the feed intake chute when the
chipper or the engine is running. Feed
wheels will pull in anything in the path
of operation and will cause severe
personal injury if a person is pulled
into feed intake wheels.
• Always load shorter pieces of wood or
brush on top of longer pieces or use
push paddle, never reach into the feed
intake chute to load these pieces.
• Stay clear of discharge zone when
running chipper. Never allow anyone
to stand near or to walk close to the
discharge zone, even if being
discharged into a bin or truck.
• Airborne debris may cause severe
injury. If inspection of chipped
material is required, shut down the
chipper and the engine first.
• Discharge spout should not be pointed
toward people, buildings, or other
personal property that may be injured
or damaged. Airborne debris is as
dangerous as any powerful projectile.
• Never position, adjust, or move the
discharge chute while the chipper or
the cutter disk are running
6
18” CHIPPER SAFETY PRECAUTIONS
f
• Always have at least 2 operators at the
job site running the chipper. One to
load the brush into the feed wheels and
the other to maintain the feed control
bar in case of an accident.
• Always feed trees and brush butt end
first and walking to the right side of
the chipper, material being fed should
be to the operator’s left side. The
material being fed tends to kick to the
left and could injure anyone on that
side.
• Never lean over material being loaded
into the feed wheels; especially small
diameter, short length material that is
still long enough to be fed into the feed
wheels alone. The material is not
heavy enough to hold down when the
feed wheels first grab it and will kick
up hitting the operator in the chin or
head causing injury.
• Never lay vine type material in front o
feed intake chute.
• Never allow yourself or your clothing
to become tangled in or tripped by vine
type material. SEVERE INJURY
COULD OCCUR.
• Always cut vine type material into
shorter, easier to handle pieces,
approximately 4 to 5 feet.
• Don’t feed the vines into the chipper
unless they have been cut!!!
• STOP automatic feed system and run
vine type material through using
manual start/stop controls and a
wooden push paddle.
CUTTER DISK
HOOD
• KEEP CUTTER DISK HOOD
CLOSED WHILE CHIPPER IS
RUNNING. Always make sure the
cutter disk hood latch pin is in place
and locked securely using a padlock
before starting chipper. The cutter
disk hood must be locked using the
factory issued lock pin and padlock.
• Never open the cutter disk hood while
engine is running. After the engine is
turned off, allow the cutter disk to
come to a complete stop before
opening the cutter disk hood. This will
take several minutes
• Never run the chipper or the engine
with the cutter disk hood open or
unlocked at any time or for any reason.
• If the cutter disk hood or hinge is
damaged, replace immediately.
• Always have the trees and brush cut to
size for the chipper before the chipper
arrives at the job site.
• It is very dangerous to run a chain saw
and the chipper at the same time.
• If a tree gets jammed and has to be
trimmed, shut down the chipper first.
7
18” CHIPPER SAFETY PRECAUTIONS
DO NOT PERFORM MAINTENANCE
OF ANY KIND ON THIS MACHINE
UNLESS:
The engine is turned off
The ignition key is removed
Positive battery cable is
disconnected
The clutch is disengaged
Feed control bar is in neutral
All machine parts have come to a
complete stop – NOTE: The cutter
disk takes several minutes to come
to a complete stop
All machine parts have had
sufficient time to cool down
The cutter disk lock pin is installed
in the disk lock tube
No operator is in position at the
controls to accidentally start
machine
At least 2 people are at the site
where maintenance is performed
More accidents occur while performing
maintenance than any other time! Use
extra caution.
Never perform maintenance with the
engine running, not even with the clutch
disengaged. The pilot bearing could seize
or freeze to the clutch shaft and permit the
clutch to engage even though the operator
thought the clutch had been disengaged.
ALWAYS REPLACE GUARDS AND
OTHER PROTECTIVE EQUIPMENT
BEFORE STARTING CHIPPER AFTER
PERFORMING MAINTENANCE.
• Keep a well-stocked First Aid Kit with
the chipper at all times.
• Keep a full Fire Extinguisher with the
chipper at all times.
• YOKE LOCK PIN MUST BE IN
POSITION before performing
maintenance between the feed wheels.
Use the hydraulic lift to raise upper
feed wheel high enough to insert yoke
lock pin as shown above.
• After the upper feed wheel has been
raised and the lock pin is in position,
place a block of wood 4” x 18” x 16”
between feed wheels to keep wheel
from coming down. See Maintenance
Section for further instruction.
• Stop engine, remove key, and
disconnect battery cable when
repairing or adjusting machine or drive
belts.
• Keep engine in good condition, service
as instructed in engine manual. Do not
touch engine while running or hot
(serious burns may result).
• Allow all machine parts to cool
sufficiently before servicing or making
adjustments. Hot machine parts can
cause severe burns.
