READ AND UNDERSTAND THE OPERATORS INSTRUCTION MANUAL THOROUGHLY
BEFORE ATTEMPTING TO OPERATE THIS EQUIPMENT.
Death or serious injury could occur if this machine is used improperly.
Extreme care must be taken when operating electric
models with water present: Ensure power cord is prop-
erly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.
•Check all electrical cables - be sure connections are tight and
cable is continuous and in good condition. Be sure cable is
correctly rated for both the operating current and voltage of
this equipment.
•Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with qualified electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and
ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The machine is equipped with a grounded plug
and must be connected to an outlet that is properly installed
and properly grounded. DO NOT modify the plug provided on
the motor. If the plug does not fit the outlet have a qualified
electrician install the proper receptacle.
•Switch motor OFF before disconnecting power.
•Engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproductive
harm.
•Gasoline is extremely flammable and poisonous. It
should only be dispensed in well ventilated areas,
and with a cool engine.
•Small gasoline engines produce high concentrations of car-
bon monoxide (CO) example: a 5 HP 4 cycle engine opera-
tion in an enclosed 100,000 cu. ft. area with only one change
of air per hour is capable of providing deadly concentrations
of CO in less than fifteen minutes. Five changes of air in the
same area will produce noxious fumes in less than 30 min-
utes. Gasoline or propane powered equipment should not be
used in enclosed or partially enclosed areas. Symptoms of
CO poisoning include, headache, nausea, weakness, dizzi-
ness, visual problems and loss of consciousness. If symp-
toms occur - get into fresh air and seek medical attention
immediately.

maintain a controlled raising/lowering of the cutters.
15. PRESSURE CONTROL ADJUSTMENT
• The last adjustment is the pressure control adjust-
ment. Depending on the material to be removed,
theoperatorcanincreaseordecreasethetensionof
the cutting head to provide a more or less aggres-
sive cutting action. If center section bounces
on surface increase pressure until it smooths out.
16. PRESSURE INDICATOR
• Adjustment of the pressure control is monitored by
the pressure indicator. (See figure 14)
17. VACUUM PORT
• For dust control use the Vacuum Port with an
appropriately sized EDCO vacuum system.

18. TLR-7
• The EDCO Traffic Line Remover (TLR-7) is an
easily operated, highly efficient machine which can
beoperatedforwardsorbackwards.Itwasdesigned
to be used at a very slow walking pace.
FLOATING HEAD FEATURE
The TLR-7 is designed to allow the cutter to float
during removal operation. Maximum movement is 3/4”.
The pressure control adjustment determines how tightly
the cutter head is held against the road surface - depth
of cut is controlled by depth control adjustment. To over-
ride the floating head feature - lower the engaging lever
and turn the depth control in the “down” position until the
cutter head is locked at the cutting depth desired. In this
position, the pressure adjustment setting will not have
any bearing on the cutting action and cutting action will
be extremely aggessive.

Grinding/cutting/drillingofmasonry,concrete,metalandothermaterialscangeneratedust,mistsandfumescontainingchem-
icals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive
harm. If you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition
of the tool being used, review the material safety data sheets and/or consult your employer, the manufacturers/suppliers,
governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other
authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recom-
mendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. Water should be used
for dust suppression when wet grinding/cutting/drilling is feasible. When the hazards from inhalation of dust, mists and
fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA
for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition may give off dust or mists
containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and
rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases,
including silicosis. In addition, California and some other authorities have listed respirable crystalline silica as a substance
known to cause cancer. When grinding/cutting/drilling such materials, always follow the respiratory precautions mentioned
above.
