These safety alert symbols identify important safety messages in this manual. When you see these symbols, be

alert to the possibility of personal injury and carefully read the message that follows.

Do not allow anyone to operate the SURFACE GRINDER without first reading this Operator Manual and

becoming familiar with its operation. The manufacturer of the SURFACE GRINDER has gone to great extremes to

provide the owner(s) and/or operator(s) with the finest equipment available for its intended job function of

removing covering materials from concrete and wood floor surfaces. Yet, the possibility exists that the SURFACE

GRINDER can be utilized in and/or subjected to job applications not perceived and/or anticipated by the

manufacturer. Such misuse and/or misapplication of the SURFACE GRINDER can lead to the possibility of

serious damage, injury or even death. It is the responsibility of the owner(s) and/or operator(s) to determine that

the SURFACE GRINDER is being utilized and/or operated within the scope of its intended job function. It is the

responsibility of the owner(s) and/or operator(s) to establish, monitor and constantly upgrade all safety programs

and/or practices utilized in and for the operation of the SURFACE GRINDER. The purpose of such programs is to

provide for owner(s') and/or operator(s') safety. Operators must be instructed to recognize and avoid unsafe

conditions associated with their work (29 CFR 1926.21 (b)(2)) and/or applicable updated revisions. It is the

responsibility of the owner(s) and/or operator(s) to determine that no modifications and/or alterations have been

made to the SURFACE GRINDER. Modifications and/or alterations can lead to the possibility of serious damage,

injury or even death. It is the responsibility of the owner(s) and/or operator(s) to make this Operator Manual

available for consultation during all phases of operation. Refer to OSHA 2207 and/or applicable updated revisions

which contains all OSHA job safety and health rules and regulations (1926 and 1910) covering construction.

CAUTION

NOTICE TO OPERATORS

DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV. #4 (05/28/09) PAGE 8

The concept of powered SURFACE GRINDER has been successfully utilized for many years as a practical

solution to many types of surface preparation requirements. The basic concept is proven and well

accepted within the associated marketplaces. Use of a SURFACE GRINDER requires strenuous work

activity. This type of work activity can be considered to be greater in magnitude than that experienced

with the use of many other types of both light construction and lawn and garden related equipment. This

type of work activity should only be attempted by operators of adequate physical size and stature, mental

awareness and physical strength and condition. The body parts most noticeably affected during any

specific process are the arms, hands, wrists, shoulders, lower back and legs. The process can also

produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body

parts. Back related pain can be a side effect of utilizing a SURFACE GRINDER. An operator with a chronic

back related problem or a history of back and/or other medically related problems should not attempt to

utilize the SURFACE GRINDER. Use of the SURFACE GRINDER may only aggravate this and any other

medically related problem. Because of the diverse type of prevailing job applications, job site conditions,

operator experience levels and operator physical characteristics, no warranty, guarantee, representation

and/or liability is made by the manufacturer as to the absolute correctness or sufficiency of any

operational procedure, operational position and/or technique. There is no absolute guarantee that an

operator of any given experience level, physical size and/or physical condition will be immune to the

possibility of and/or probable physical side effects of the normal use of the SURFACE GRINDER. Each

potential operator must be made aware of and assume the operational and physical liability described

and/or associated with the use of the SURFACE GRINDER. Improper use of the SURFACE GRINDER can

result in property damage and/or personal injury, including death. Each potential operator not willing to

assume the operational and physical liability described and/or associated with the use of the SURFACE

GRINDER, should not operate it. Proper levels of operator experience, skill and common sense are

essential for maximizing the safe and efficient operation of the SURFACE GRINDER.

SAFETY PRECAUTIONS

DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV #4 (05/28/09) PAGE 10

THE FOLLOWING SAFETY PRECAUTIONS

PROVIDE SOME COMMON SENSE GUIDES TO

PROMOTE SAFETY AND EFFICIENCY WITH THE

SURFACE GRINDER. NO WARRANTY,

GUARANTEE OR REPRESENTATION IS MADE

BY THE MANUFACTURER AS TO THE

ABSOLUTE CORRECTNESS OR SUFFICIENCY

OF ANY INFORMATION OR STATEMENT. THESE

SAFETY PRECAUTIONS ARE INTENDED TO

DEAL PRINCIPALLY WITH COMMON

PRACTICES AND CONDITIONS ENCOUNTERED

IN THE USE OF THE SURFACE GRINDER AND

ARE NOT INTENDED TO BE ALL INCLUSIVE.

PROPER LEVELS OF OPERATOR EXPERIENCE,

SKILL AND COMMON SENSE ARE ESSENTIAL

FOR SAFE AND EFFICIENT OPERATION.

THE ENGINE EXHAUST FROM THIS PRODUCT

CONTAINS CHEMICALS KNOWN TO THE STATE

OF CALIFORNIA TO CAUSE CANCER, BIRTH

DEFECTS OR OTHER REPRODUCTIVE HARM.

THIS STATEMENT IS MADE IN COMPLIANCE TO

CALIFORNIA PROPOSITION 65.

INCORRECT USE OF THE SURFACE GRINDER

CAN RESULT IN PROPERTY DAMAGE,

PERSONAL INJURY OR EVEN DEATH. TO

REDUCE THIS POSSIBILITY, GIVE COMPLETE

AND UNDIVIDED ATTENTION TO THE JOB AT

HAND AND FOLLOW THESE SAFETY

PRECAUTIONS:

PREPARATION.

1) This SURFACE GRINDER is specialized type of

powered equipment, designed for aspecific job

function and requires adequate and thorough

instruction BEFORE it is operated. The size,

power, complexity and operating characteristics

of this type of powered equipment would dictate

that each operator must receive adequate,

professional instruction regarding the proper

operation of this SURFACE GRINDER before

being allowed to utilize it. BEFORE attempting to

utilize this SURFACE GRINDER, read this

Operator's Manual, the applicable Safety and

Operating Information Video Tape and the

material supplied by the engine manufacturer to

familiarize each operator with its correct

operating procedures. Avoid the urge not to take

the necessary time to read this Operator's

Manual before operating the SURFACE

GRINDER. DO NOT OPERATE THE SURFACE

GRINDER UNTIL EACH OPERATOR

COMPLETELY COMPREHENDS THE

CONTENTS OF THIS MANUAL AND THE

APPLICABLE SAFETY AND OPERATIONAL

INFORMATION VIDEO TAPE.

2) Develop acomprehensive program for the safe

operation of the SURFACE GRINDER by its

owner(s) and/or operator(s). Such aprogram will

include, but is not limited to: instructional

requirements for operation, applicable OSHA

requirements, local laws and regulations, job site

safety and aSURFACE GRINDER maintenance

program. Constantly examine and upgrade this

program to guarantee owner(s) and/or

operator(s) safety. Each operator must be fully

instructed regarding the specifics of this safety

program.

3) Determine that the SURFACE GRINDER is in its

original, factory configuration and has not been

modified in any manner. Many modifications can

result in potentially dangerous configurations

that can lead to property damage and/or

personal injury. If there are any questions about

possible modifications made to the SURFACE

GRINDER, contact the Customer Service

Department for specific information BEFORE

utilization. There is no charge for this service.

Do not operate the SURFACE GRINDER

without the use of the original equipment V-belt

guard. Use of the SURFACE GRINDER without

an approved belt guard can lead to property

damage and/or personal injury.

4) Minors should never be allowed to operate the

SURFACE GRINDER. Bystanders, especially

children and animals, should not be allowed in

the areawhere the SURFACE GRINDER is in

use. The grinding process can result in flying

particles being emitted at high velocity and

striking the operator and/or onlookers. This can

lead to the possibility of property damage and/or

personal injury. Keep all body parts, loose

clothing, foreign objects and onlookers clear of

the rotating discs, multi-accessory attachments

and flying particles.

5) Operators must be in adequate physical

condition, mental health and not under the

influence of any substance (drugs, alcohol, etc.)

which might impair vision, dexterity or judgment.

Working with the SURFACE GRINDER is

strenuous. If you have any condition that might

be aggravated by strenuous work, check with

your doctor BEFORE operating the SURFACE
