Safety Indicator Signal Words
The following signal words and colors are used throughout this document to
indicate safety hazards. Pay careful attention when you see them. The level of
severity differs for each signal word and color.
Signal words are accompanied by graphics showing what personnel should or
should not do. The graphics are called safety symbols and are defined starting on
page xx, but more specific text is provided every time a graphic is used throughout
the manual. Everyone near the machine must be trained on how to read these
safety indicators.
Failure to comply with the instructions accompanying each signal word may result
in property damage, personal injury, or even death. Personnel must follow all
safety procedures and practices to ensure the safest possible operation of this
equipment. However, at no time is this document a substitute for common sense.
Personnel must ensure that the work environment is safe and free of distractions.
Danger Indicates an imminently hazardous situation which, if not avoided, is
likely to result in death or serious injury.
Warning Indicates a potentially hazardous situation, which, if not avoided,
may result in death or serious injury.
Caution Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
Notice Calls attention to information that is significant to understanding the
operation at hand or the potential for property damage.
Environmental Applies to conditions that may affect the environment but do not
have an immediate, direct effect on personnel or equipment.
Signal words are used in conjunction with safety symbols
to give hazard messages throughout this manual.
Common safety symbols are defined starting on page 12.

General Safety & Equipment Rules
Because it is impossible to anticipate every circumstance that might involve a
hazard, the safety information provided in this equipment manual and on the
machine is not all-inclusive. If this machine is operated or serviced using a
procedure not specifically recommended by the manufacturer, the procedure shall
be approved by a professional engineer to ensure it will not render the equipment
unsafe. Use extreme caution and common sense at all times.
Safety Rules
Know Your Equipment
• Read this manual completely before using or maintaining the equipment. Do
not operate this machine unless you have a thorough knowledge of the
controls, safety devices, emergency stops, and operating procedures
outlined in this manual.
• Read and follow all safety notes. Failure to comply with these instructions
may result in economic loss, property damage, and/or personal injury
including death.
• Refer to the lockout/tagout guidelines on the following pages to safely
perform maintenance and troubleshooting of this equipment.
• Observe and obey all safety labels. Replace worn labels immediately.
• Use this equipment solely for the purpose described in this manual.
• Only qualified personnel should attempt to operate or perform maintenance
on this equipment. “Qualified personnel” is defined as:
...a person or persons who, by possession of a recognized degree or certificate of
professional training, or who, by extensive knowledge, training, or experience,
has successfully demonstrated the ability to solve problems relating to the subject
matter and work—ANSI B30.2-1983
...one who has skills and knowledge related to the construction and operation of
the electrical equipment and installations and has received safety training on the
hazards involved—NEC 2002 Handbook
Personal Safety
• Always wear safety glasses and hearing protection in an industrial
environment.
• Utilize a filtering face piece (dust mask) when working near sawdust.
• Wear proper clothing and appropriate personal protective equipment (e.g.,
safety glasses and hearing protection.) Do not wear loose clothing or
jewelry. Confine long hair by tying it back.
• Use caution when lifting heavy parts or material.

Twin-Axis Sheathing Saw: Safety
Installing the Equipment
• Follow installation instructions completely.
• Use proper lifting equipment rated for the proper weight.
• This equipment is not for use in a residential area.
Keeping a Safe Environment
• Pay attention to your surroundings.
• Keep children away. All visitors should be kept a safe distance from the
work area. Hazards may not be apparent to individuals unfamiliar with the
machine.
• Keep work areas well lit.
• Keep the work area clean and free of any trip or slip hazards.
• Do not use the equipment in damp or wet locations, or expose it to rain or
snow.
• Minimize dust clouds and protect your equipment by cleaning dust in this
manner:
a) Shut down electrical power and sources of ignition
b) Vacuum dust prior to blowing with air
c) Powered cleaning equipment such as vacuums must be consistent
with local governmental codes for use in dusty conditions.
Operating and Maintaining the Equipment
• Ensure that all people, tools, and foreign objects are clear of the restricted
zones before operating this equipment. The restricted zones are shown
on page xix.
• Perform safety tests to ensure all E-stops are working properly before
operating the equipment at the initial startup, after performing any
maintenance, and in accordance with the maintenance schedule.
• Always push an E-stop button before approaching a machine for any
reason. An E-stop may cause components to move without warning.
• Only use procedures described in this manual. Any other procedures should
be discussed with MiTek to verify it is done safely. For topics not covered in
this manual or online, contact MiTek for advice.
• In case of machine malfunction, stop the machine immediately using an E-
stop, lockout/tagout, and report the malfunction to a supervisor.
NOTICE
Never use compressed air inside an electrical enclosure. It
may force contaminants into electrical connections.
Use a vacuum to remove dust from electrical enclosures.
Canned air is acceptable after vacuuming.

Twin-Axis Sheathing Saw: Safety
• Never leave the machine running unattended. Turn the power off! Do not
leave the machine until all parts have come to a complete stop and all
electrical power has been shut off.
• Check for worn or damaged parts regularly. Repair or replace them
immediately.
• Only use exact replacement parts specified. Using unapproved parts may
void the warranty and can be a safety risk.
• Keep the hydraulic, pneumatic, and electrical systems in good working
order at all times. Repair leaks and loose connections immediately. Never
exceed the recommended pressure or electrical power.
• Check that all guards and safety devices are in place and in working order
before each shift starts. All protective guards and safety devices must be in
place before and during use of the machine. Never disconnect or bypass
any safety device or electrical interlock.
• Torque bolts and fasteners to the specifications given by MiTek. If no torque
specification is given, use industry standards.
• Only qualified maintenance personnel shall make adjustments or remove,
repair, or install safety devices. Only qualified electricians should perform
electrical work.
• Periodically inspect the quality of the finished product.
• Document all preventive and repair maintenance over the life of the
machine to improve machine efficiency and reduce the risk of accidents.
Electrical Safety Notes
• Do not use any liquids in the interior of electrical cabinets.
• When using solvents on and around the machine, remove power to the
machine to eliminate the chance of sparking, resulting in explosion or fire.
Wear a respirator approved for use with solvents.
