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 ordi-
nances.
•NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The motor 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 electri-
cian 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 operation
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 minutes.
Gasoline or propane powered equipment should not be used
in enclosed or partially enclosed areas. Symptoms of CO poi-
soning include, headache, nausea, weakness, dizziness,
visual problems and loss of consciousness. If symptoms oc-
cur - get into fresh air and seek medical attention immediately.

Electric Models:
(5 HP Baldor. Available in 1 Phase or 3 Phase)
Dry Grinding:
DryGrindingcreatesa large volume ofairbornedust. Forhealth reasons, the operator shouldwearan
applicable respirator. The dust may contain chemicals known to cause serious illnesses, including Silicosis -
a fatal disease of the lungs. Check the chemical properties of the material to be removed and follow all EPA/
OSHAregulations.
• AnIndustrialvacuum,capableofhandlinghigh volume of fine dust,such astheVAC -
160 (Figure 5), should be used when dry grinding with this machine. If the material
being used is hazardous or contains Silica - the vacuum unit should be capable of
removing Respirable Silica and hazardous particles of less than 3 microns and if
necessary, have the capability to be equipped with a HEPAfilter.
Most standard drum type units use a paper bag filter. The dust created during
grinding is extremely fine and will clog the filter bag of these units and eventually
damagethevacuums motor. Inaddition,damageto theTG-10engine could occur.
• Thecollecteddebrisand filters should be disposed ofaccordingtoproceduresthat
comply with current EPA/OSHAstandards.
Electric units must be connected to a properly grounded
electricalsystemusinganapprovedelectricalcable.
To Start the Machine:
•Tilt the machine back slightly, just enough for the disc to be clear of the slab surface.
•Press the ON button on the power box.
•Gently set the machine back down until the disc touches the slab surface and begin moving the machine.
To Stop the Machine:
•Tilt back the machine to allow the disc to clear the slab surface.
•Press OFF on the power box.
Wet Grinding:
• In the wet grinding stage - water is fed from a standard garden hose into a
ball valve cut off, then into a nozzle that sprays over the disc assembly. (Figure 4)
Use the ball valve to regulate the flow of water to the disc.
Only use enough water flow to reduce dust. Excess water flow will
create clean up problems and could cause a hazardous walking area.

Discs:
• Inspect the disc (Figure 8) periodically to determine it’s wear characteristics, if signs of
unevenwearappear the causeshouldbe determined andcorrected. Ifrepairs are
neededcontactEDCO oryourEDCO representative.
• Each new machine is shipped with a 10”/255 mm factory balanced disk. It is important
to maintain the coupling to which the disk is attached. Aworn coupling, damaged
bearings or a bent shaft will cause the grinding discs to wear unevenly. (Figure 9
shows the head assembly.)
Controlling the Grind:
• Grinding discsare extremely aggressive. It is important to KEEP THE GRINDER MOVING IN A SIDE-TO-SIDE
MOTION, do not let the grinder stay in one spot, even for a few seconds, or the surface will be damaged. When
grinding is completed, tilt the machine back and shut off the power.
• This tool is primarily used to remove excess or damaged concrete surfaces (high joints, slab curling, bridge, road
surface, extra hard surface concrete of 7000 p.s.i. or greater) quickly and at a controlled rate. It is not designed to
produce a smooth, polished finish; it will always leave faint “rings” in the surface. While this is not objectionable for
bridgeworkorother removal work, it will definitelyshowthrougha painted surface or under thinvinyltile.
• To achieve a smooth“polished”surface,completethe grinding operation with anEDCOdualdiscunit using
grinding stones or dyma serts.
• Toremovealight coating, movethegrinder quickly. Forheavierremoval,move the grindermoreslowly.
• Keep the grinding disc flat - do not attempt to grind against vertical surfaces. Be sure the machine is in the correct
operatingposition.(SeeFigures 6 and 7below..)
