Safety Instructions
Owner’s Responsibility
To maintain machine and user safety, the responsibility
of the owner is to read and follow these instructions:
• Follow all installation instructions.
• Make sure installation conforms to all applicable
Local, State, and Federal Codes, Rules, and
Regulations; such as State and Federal OSHA
Regulations and Electrical Codes.
• Carefully check the unit for correct initial function.
• Read and follow the safety instructions. Keep them
readily available for machine operators.
• Make certain all operators are properly trained,
know how to safely and correctly operate the unit,
and are properly supervised.
• Allow unit operation only with all parts in place and
operating safely.
• Carefully inspect the unit on a regular basis and
perform all maintenance as required.
• Service and maintain the unit only with authorized
or approved replacement parts.
• Keep all instructions permanently with the unit
and all decals/labels/notices on the unit clean and
visible.
• Do not override Secondary Button safety feature.
• Optimal Operating Pressure - 120-140 PSI.
• Always assume HTS Sealing Device is pressurized
while handling.
NOTE: Stop use and immediately remove from service
any unit that has experienced damage.
NOTE: Only apply pressure to the Mobile Cart version
at the time of use. Disconnect and drain All Air Pressure
from cart when not in use through the foot-operated
drain valve.
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.
