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 qualied 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 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 t the outlet have a qualied 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 reproduc-
tive harm.
• Gasoline is extremely ammable and poisonous.
It should only be dispensed in well ventilated areas,
and with a cool engine.
•Small gasoline engines produce high concentra-
tions of carbon 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 fteen minutes.
Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane pow-
ered equipment should not be used in enclosed or partially
enclosed areas. Symptoms of CO poisoning include, head-
ache, nausea, weakness, dizziness, visual problems and
loss of consciousness. If symptoms occur - get into fresh
air and seek medical attention immediately.

Operational Keys to good machine care and long life...
1. Before each use, check and insure all hardware, nuts, bolts and ttings are tight
and not worn or damaged. If damaged or missing hardware is noted, it should be
replaced before the machine is put back into service.
2. If using attachments such as a vacuum for dust control, insure lters are clean and
the vacuum is empty before each use and empty often for best vacuum performance.
Check hoses, gaskets, seals and lters for damage. If any damage is found the part
or parts should be replaced. Dirty or damaged lters and leaking gaskets or seals will
cause poor vacuum performance, penetrate and shorten the life of any motor and
cause uncontrollable dust which is hazardous to ones health.
3. Check the maintenance schedule for important information about lubrication
intervals. Remember, machines used in a dusty environment have a more frequent
lubrication requirement than a machine that is not used in a dusty environment.
4. Machines that have electric motors should be checked for proper voltage settings
by checking the name plate on the motor for the dierent electrical congurations i.e.:
single phase, three phase and the voltage settings available. This is not required on
single voltage motors i.e.: 120 Volt Single Phase. The power cords and/or extension
cords should be checked for proper length and gauge, remember, the longer the cord
a heavier gauge wire is required. Too small a gauge wire causes a voltage drop which
in turn causes motor overheating and damage. Check all wiring for cuts, bare or ex-
posed wire and damaged connectors or plugs. These items can cause fatal shocks
under the right conditions. It is current that kills, not voltage.
5. After each days use, the machine should be cleaned. When cleaning electric
powered machines, cover any openings to prevent contaminants from entering the
motor.

TROUBLESHOOTING AND SERVICING
AN SEC SINGLE DISC GRINDER
The Grinder and Other System Components:
On any concrete surface preparation equipment
there are numerous components that could be
the root cause of any type of problem. Therefore
take time to analyze any problem that might arise,
a little thought and patience can save many hours
of down time and frustration.
It is simply a mechanical device designed to ef-
ciently remove trowel marks, rain spots, excess
concrete, rough nishes or high spots. Remove
1/32” (1mm) of material per pass.
If the machine is forced into the work surface it
can cause unnecessary vibration and noise. The
expected results will not be attained.
As with any mechanical equipment, an ounce of
prevention is worth a pound of cure. You can pre-
vent most problems and need for repair with routine
preventative maintenance. Much like maintaining
your automobile, many preventative measures are
simple visual checks of oil, lters, lubrication points,
loose hardware and leaks.
Seals around the skirt assembly are provided for
dust control, worn, broken or maladjusted seals
will not provide this control.
Guards are provided for personal as well as ma-
chine safety and protection. They are intended to
be in place at all times during storage, turn around,
operation and only removed for servicing. Foreign
objects could fall into the works of the machine
unnoticed and cause personal injury and damage
when the machine is turned on.
Most parts of the machine cannot be seen from
the outside. For a complete breakdown of the
machine, any single component or troubleshooting
refer to the following pages for detailed informa-
tion.
System Checklist:
Begin with this simple checklist:
1. Is the source power what it should be or is the
voltage too high, too low or nonexistent?
2. Is the drive system loose or worn?
3. Are the insert mounted rmly on the disc?
4. Are any of the insert missing or damaged
and all of the same type.
5. Are the lubrication points lubricated properly?
6. Is all the hardware tight?
7. Are the inserts wearing evenly?
Common Problems:
If you have checked these items and a problem
still exists, you should analyze the nature of the
problem and the possible causes. While we will
not cover all of the possibilities, these are the most
common problems and their probable causes.
Excessive Noise:
Excessive noise is most often caused by loose
components of the machine to include bolts or
any adjustable function that is not tightened after
adjustment is made.
Excessive Vibration:
Vibration can be caused by a loose motor mount,
out of balance grinding disc or missing and worn
inserts. Motor and drive shaft sheaves out of align-
ment.
Leaking Lubricants:
Leaking lubricants can be caused by over heating,
worn or bad bearings and over lubrication.
Loss of Power:
A loss of power can be caused by over tightened
belts, low voltage, defective wiring or pushing the
machine into the work to forcefully and/or adding
to much weight to the machine.
Poor Grinding or Cutting:
Worn or missing inserts. Mixed inserts on the same
disc. Wrong insert for the type of surface you are
working on or the type of material you are trying
to remove. Is the right machine being used for the
job?

PROCEDURE FOR LUBRICATING FLANGE BEARINGS
To grease the ange bearings attach the grease gun to the grease ttings as shown in the above photos
and give only two (2) pumps on the grease gun weekly. If excessive over lubrication is done grease will
leak onto the work surface causing possible damage and wasted cleanup time.
If using a vacuum for dust control attach it to the vacuum port located on the rear of the handle securing
it as shown in photo above.

PROCEDURE FOR ADJUSTING OR REPLACING DRIVE BELT
To adjust the drive belt loosen four (4) bolts securing
the motor mount to the frame.
Slide the motor mount to the rear of the machine to
increase belt tension.
Tighten the four (4) bolts loosened earlier maintaining
pressure on the motor mount to prevent loosening.
To replace the belt, remove the hood by removing two
(2) bolts, one on each side of the machine.
Loosen the four (4) bolts as in the rst step and slide
the motor mount all the way forward.
Remove the belt from the motor and driven shaft
sheaves as shown in the photo on the left.
Reverse the previous step to install new belt. Slide mo-
tor mount towards the rear of the machine and adjust
belt tension, tighten all four (4) bolts as explained above.
Replace hood and tighten bolts.
NOTE:
While cover is removed check to see if there are any
remnants of grease from servicing on any of the sur-
faces, remove and dispose of properly.
