Operator Protective
Equipment
Personal protective equipment helps make tire servicing safer. However, equipment does not take the
place of safe operating practices. Always wear durable
work clothing during tire service activity. Loose fitting
clothing should be avoided. Tight fitting leather gloves
are recommended to protect operator’s hands when
handling worn tires and wheels. Sturdy leather work
shoes with steel toes and oil resistant soles should be
used by tire service personnel to help prevent injury in
typical shop activities. Eye protection is essential during tire service activity. Safety glasses with side
shields, goggles, or face shields are acceptable. Back
belts provide support during lifting activities and are
also helpful in providing operator protection.
Consideration should also be given to the use of hearing protection if tire service activity is performed in an
enclosed area, or if noise levels are high.

safety and operating instructions thoroughly before using the tire changer.
ALWAYS

ALWAYS
cover the electric motor and switch box
before hosing down the tire changer. Be sure water
does not enter the motor or switch box.
ALWAYS
disconnect the electric power and air sup-
ply before attempting any maintenance.
ALWAYS
keep all working surfaces clean and free of
tire lube buildup.
ALWAYS
be aware of what each person is and will do
before attempting any two-person operation.
Bead Loosening
NEVER
place anything between the bead loosener
disc and the tire/wheel.
NEVER
place any part of your body between the
bead loosener disc and the tire/wheel, severe bodily
injury may result.
NEVER
allow the bead loosener to contact the
wheel, wheel damage may occur.
Demounting & Mounting
NEVER
stand on the working table while demount-
ing or mounting a tire.
ALWAYS
keep hands, feet, and other objects away
from moving parts while the machine in turned on.
ALWAYS
place the narrow bead seat to the outside
when clamping. Failure to demount the tire from the
narrow bead seat side may cause damage to the tire
beads.
ALWAYS
apply an approved rubber lubricant to rim
flanges and both tire beads before demounting or
mounting and seating the beads.
NEVER
use
antifreeze, silicone, or petroleum base lubricants.
ALWAYS
clean and inspect the wheel.
NEVER
mount a tire on a damaged or rusty wheel.
Wheel damage or rust may cause tire or wheel failure
during inflation. Explosion from failure may result in
severe injury or death of the operator and bystanders.
ALWAYS be sure the bead opposite the tool is in the
drop center before rotating the tire when demounting
or mounting to avoid damage to the tire beads.
Inflation
ALWAYS follow all applicable Local, State, and
Federal Codes, Rules, and Regulations; such as the
Federal OSHA Standard Number 1910.177.
NEVER
seat beads or inflate a tire on the tire
changer. The H.I.T. 9000 is not designed as a safety
device or stand for bead seating or inflation.
ALWAYS
use an approved inflation chamber or infla-
tion cage.
The following safety instructions are for one piece
wheels only. Refer to the manufacturer’s or R.M.A.
procedures for multipiece wheels.
ALWAYS
use an approved inflation chamber or inflation cage equipped with a grip chuck and a remote
inflation gauge and valve. DO NOT OVER INFLATE!
Tire or wheel failure during and after inflation may
result in an explosion capable of causing severe injury
or death.
ALWAYS
inflate the tire to manufacturer’s recom-
mended cold operating pressure.
NEVER
reinflate a tire that has been run underinflated or flat without first demounting the tire and
checking for wheel and tire damage.
ALWAYS
inspect the tire interior for loose or broken
cords, cuts, penetrating objects, and other damage to
the carcass. Discard tires that cannot be properly
repaired.
NEVER
rework, weld, heat or braze wheels.
NEVER
strike the tire or wheel with a hammer.
ALWAYS
be sure the tire diameter exactly matches
the wheel diameter.
Tire failure under pressure can be hazardous. Place the wheel inside an approved
inflation chamber or cage before inflating.
Use an approved remote inflation valve,
hose, and gauge. ALWAYS wear safety goggles for eye protection. Do not stand beside
the wheel or cage during inflation. Keep
hands and other parts of the body out of
the cage during inflation. Observe the tire
pressure frequently. Do not exceed the
manufacturer’s recommended maximum
inflation pressure. Failure to follow these
instructions may cause the tire and rim to
separate with tremendous force, resulting
in serious personal injury or death.
