QUALITY ASSURANCE/ MACHINE BREAK IN
The Contec Floor Grinder is the product of extensive engineering development designed
to give long life and unmatched performance. The Floor Grinders are shipped completely
assembled.
You can help ensure that your Floor Grinder will perform at top levels by observing a
simple routing on first use. Consider that your new Grinder is like a new car. Just as you would
break in a new car to the road or any new machine to the job, you should start gradually and
build up to full use. Learn what your machine can do and how it will respond. Full throttle and
control may be used after this time period, as allowed by material. This will serve to further
break in the machine on your specific application, as well as provide you with additional
practice using the machine.
We thank you for the confidence you have placed in us by purchasing a Contec Floor
Grinder and wish you many years of satisfied use.

ROUTINE SERVICE INTERVALS
Due to the nature and environment of use, Floor Grinders could be exposed to severe
operating conditions. Some general maintenance guidelines will extend the useful life of your
machine.
• The initial service for your grinder should be performed after 25 hours of use, at which time
your mechanic (or authorized repair shop) should complete all the recommended checks in the
schedule above. The maintenance log is handy for keeping a record of the maintenance
performed and the parts used for servicing your grinder.
• Regular service according to the schedule above will prolong the life of the floor grinder and
prevent expensive repairs.
• Keeping your floor grinder clean and free from debris is the single most important regular
maintenance operation, over and above the checks in the service schedule above, that can be
performed. After each use your grinder should be cleaned to remove any dust and debris from
the undercarriage and surrounding components.
• In the Service Schedule above, items that should be checked, replaced or adjusted are
indicated by “o” in the appropriate column. For ease of recording place, a checkmark through
the “o” when the item is complete. If an item is not required or not completed place an “x”
through the “o” in the box.
• Failure to have your floor grinder regularly serviced and properly maintained in accordance
with the manufacturer’s instructions will lead to premature failure and void the warranty.

OPERATING SAFETY PRECAUTIONS
The ALPHA floor grinders are constructed according to existing safety rules and
regulations. These technical precautions should not be removed or changed under any
circumstances. While operating the machines the following points should also be kept in mind:
The instructions provided in this manual are done so to ensure the operator’s safety as well
as that of others, the equipment, and the job site. Failure to follow these guidelines can lead to
serious personal injury and even death. The operator and any service personnel should read
and understand the entire manual before working with or servicing any Contec Floor Grinder.
•The grinders should always be operated with all safety covers and technical precautions.
•During transport, cleaning, repair or maintenance the grinder must be disconnected from
the power supply. That also applies to the changing of tools.
•The safety ring (Diagram No. 17) can only be removed while operating the machine
directly against the wall. While operating the machine without the safety ring dust can be
generated. In this case the operator must wear a mask. In all other cases the grinder
must be operated with the safety ring.
•The operator should never leave the machine unattended during operation.
•Before leaving the machine, all rotary parts should be brought to a standstill. Electric
models must be disconnected from the power supply. Make sure that the machine
cannot roll or move by itself.
•After any maintenance and adjustment all safety covers must be reattached.
•Ear protectors must be worn.
•Eye protectors must be worn.
•Safety shoes with steel caps must be worn.
•In the event of a large amount of dust during operation, connect a dust collector to the
grinder.
•Depending on the floor (floor coating) grinding can produce gases. The operator must be
held responsible if these generated gases are dangerous and if protection is necessary.
Grinding floors containing asbestos is especially dangerous and can cause health
problems. Special masks must be worn which keep the breathing air clean. A dust
collector must be used and should be equipped with filters suitable for asbestos dust.
•The floor must be brushed before grinding because loose material could get into the
tools and fly away. Anchor screws and bolts coming out of the floor can also be seen
better if the floor is clean. If the grinding head hits a anchor screw or bolt then serious
damage can be caused to the machine or grinding head.

OPERATION INSTRUCTIONS
SETTING UP YOUR ALPHA GRINDER
Your Alpha Floor Grinder comes fully assembled with handle and motor fully installed.
The handle is folded to allow for easier transportation. The handle can be moved into operating
position by loosening the black knob and unfolding the handle into the up-right position. The
black knob can then be reinstalled to secure handle in place. Tooling can now be installed, and
your Floor Grinder is ready for use.
PRIOR TO OPERATION
•Make sure that all dust, debris etc., are thoroughly removed from the unit prior to
operation. Special effort should be given to the bottom of the machine where the tooling
plate is located.
•Check all bolts and screws for tightness and make sure all bolts and screws are securely
tightened. Loose bolts and screws may cause damage to the unit. Make sure tooling is
properly installed.
CHANGING OR INSTALLING TOOLING
•Tilt the machine onto the back wheels and rest it on the handlebar.
•All tool discs are fixed with three Allen screws to the tool bracket.
•Remove the screws with an 8mm Allen key.
•Check the grinding tool for wear and tear for the next application.
•Fix new tools
•Adjust the different heights of the tools by changing the position of the rear wheel swing.
The motor axis of the grinder must be 90° level to the floor.
ATTENTION: Before working on the grinder bring the motor to a total stand still and
disconnect from the power supply.
CAUTION: Tools can be hot after use.

OPERATION
Operating
After mounting the appropriate tools, the operation of the grinder can begin.
Adjust the grinder by loosening the screws of the rear wheel swing (Appendix diagram No. 3)
and changing its position in the slots so that the motor axis is 90° level to the floor. Tighten the
screws again. Connect the grinder to the mains. Lift the tool from the floor by tilting the machine
onto its back wheels. Switch the motor on.
After the motor has reached full speed, place the grinding head carefully on the floor. If the
machine is correctly adjusted (see above) it is easy to move across the floor. If the machine
pulls to the left or right, the machine must be re-adjusted by changing the position of the rear
wheel swing (see above).
Dust emission should be prevented by connecting a dust collector.
Stopping Procedure
Before finishing the grinding process the machine must be switched off and the tools must be
brought to a standstill by letting them touch the floor. Disconnect from the power supply.
ATTENTION: When switching on the motor, the machine may jump slightly due to
rotating tooling.
ATTENTION: Never switch on machine while the grinding head is on the floor.
