In addition to these Operating Instructions, general and legal regulations
regarding accident prevention and environmental protection must be complied
with per local regulations.
Such duties may, for example, relate to the handling of hazardous substances,
or the provision and wearing of personal protection equipment, as well as
compliance with traffic regulations.
The Operating Instructions must be supplemented by other instructions,
including the duty to supervise and report incidents relating to particular
working practices, for example work organization, work procedures and
personnel safety.
Personnel entrusted with working with the machine must read and understand
the Operating Instructions before starting work, paying specific attention to the
Safety information. To read these instructions after work has commenced is too
late. This particularly applies to incidental activities such as setting up the
equipment, carrying out maintenance work or training staff to work with the
Indicates where consultation with the manufacturer is
required.
Instructions relating to periodic checks.

machine. Personnel must also read all supplemental manuals from other
manufacturers.
From time to time the working practices of the operators are to be checked by a
supervisor, especially regarding awareness of safety and hazards.
Observe all applicable local, state and Federal safety regulations that pertain to
the equipment, the products being operated and the substances being removed
from the surface.
Operators must tie back long hair and avoid wearing loose clothing or jewelry,
including rings. There is a risk of injury by items getting caught, or being drawn
into moving machinery.
The use of appropriate gloves and non-skid footwear are recommended when
working with this machine.
Follow the OSHA and other applicable regulations for approved respiratory
protection standards when operating this machine in a dry operation with a dust
collector to avoid possible airborne contaminants. Grinding and cutting
concrete produces dust that may generate airborne respirable crystalline silica
which can lead to silicosis and death.
Do not use in dry operation without an approved dust collector system to
reduce or eliminate the escape of potentially hazardous or nuisance dust into
the environment.
All safety and hazard notices at or on the machine must be kept complete and
legible.
If safety-critical changes occur to the machine or its working method, the
machine must be shut down immediately. The cause of the fault must be
established and remedied.
This applies in particular to the fitting and adjustment of safety devices.
Use personnel protection equipment as required by OSHA and
other local regulations! Take notice of all safety and hazard
notices on the machine!

Before starting the machine, survey the work area for hidden obstructions
and/or uneven cracks or joints.
Do not expose machine to rain or use in standing water conditions.
Keep work area well lit.
Do not allow machine to cross over the edge of the concrete slab or work
surface.
Keep work area clean. Cluttered work areas and debris buildup on floors
creates an unsafe work environment.
Avoid flammable liquids or gases. Power tools produce sparks during
operation and when starting or stopping electric motors. Never use machinery
in dangerous sites containing materials that are combustible or explosive.
Keep children and visitors away from the work area at all times.
Refer to the MSDS of all substances in and around the machine and follow the
appropriate safety guidelines associated with the use/exposure of the
substance.
Never pull machine by power cord, run over cord with machine or forklift, or pull
on cord by extending machine distance from power source too far. Connect
power cord to power source and power cable extensions with approved plugs
All persons in the proximity of the machine must wear OSHA
approved ear and eye protection, as well as safety shoes. In
addition, the machine operator must wear close fitting protective
clothing.

from machine before turning it on.
Watch what you are doing. Use common sense. Do not operate machine
when you are not fully alert.
Do not operate machine while under the influence of drugs, alcohol, or any
medication.
Before any use of the machine, check for damaged parts that should be
replaced. Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting of cutter on diamond tools and any other condition
that may affect machine operation. A guard, power switch or other part that is
missing or damaged should be properly repaired or replaced by an authorized
service center. Do not operate machine if power switch does not turn machine
on and off.
Do not remove guards or covers that have been factory mounted. They
perform important safety roles. Keep them in the proper positions.
Extra care must be taken to ensure that tools are correctly mounted on the
correct holders and that tool holders and mounting brackets are secured in their
proper position. Damage to the tools, holders and floor surface and/or injury

engineering regulations.
2.6 DEFINITION OF THE SAFETY OFF POSITION
2.7 GENERAL SAFETY CONSIDERATIONS
Any machine, if it is not used according to regulations, may be
hazardous during operation, set-up and servicing. The machine
owner is responsible for compliance with the safety regulations
during operation and maintenance, and for the use of safety
devices supplied with the machine, as well as the provision of
appropriate additional safety devices!

The electrical components of the equipment must be inspected regularly.
Defects such as loose connections or scorched cables must be replaced
immediately. Call a skilled electrician or our Customer Service.
A second person must be in attendance while the electrician is working on the
equipment.
The work area must be secured against any third party entering the work area,
by means of a red and white safety chain and a danger sign. Use only tools that
are insulated against electricity.
Only start work after you are familiar with the electrical engineering regulations
that apply to the local area.
Only use multi-meters that complies with the regulations when troubleshooting.
From time to time check multi-meters to ensure that they are operating
correctly.
Before connecting machine to a power source, be sure the voltage supplied is
the same as that specified on the nameplate of the machine or motor. A power
source with voltage greater than that specified for the machine can result in
serious injury to the user and damage to the machine. If in doubt, do not plug
in machine. Using a power source with voltage less than the nameplate rating
is harmful to the motor.
2.8 ELECTRICAL ENGINEERING REGULATIONS
Work on electrical equipment may only be performed by a skilled
electrician or by trained persons under the supervision of a skilled
electrician, as well as in accordance with the local electrical
engineering regulations.
Use only extension cables, used for extending the main cable, that
are sized and marked in accordance with the overall power
consumption of the machine and the U. S. National Electric Code
guidelines.

It is important that the operator understands the electrical requirements for
using extension cords. The length of extension cord should be limited to the
electric
supply limitations and should never exceed 100ft in length. In addition, you
should only use (3) three conductor cords on the single-phase machines. Make
sure that any extension cord used is in good condition. Disconnect the power
source and replace or repair damaged cords and plugs before starting the
machine.
When using an extension cord, be sure to use a cord heavy enough to carry the
current the machine will draw. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. See Section 3.0 for the
table showing the correct size and type of conductor to use, depending on cord
length
and nameplate ampere rating. If in doubt, use the next heavier gauge. As the
gauge number decreases, the cord thickness increases.
When a machine is used with any extension cord, be sure to use plugs and
receptacles rated for proper voltage and amperage as prescribed by the
National Electric Code. Make sure that all extension cords are wired the same,
matching wire colors and that the ground wire (green) is secured in its proper
position.
