DEFECTS OR OTHER REPRODUCTIVE HARM.
THIS STATEMENT IS MADE IN COMPLIANCE TO
CALIFORNIA PROPOSITION 65.
INCORRECT USE OF THE LONG REACH AIR TOOL
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) The Long Reach Air Tools are a specialized type of
powered equipment, designed for specific job functions
and require adequate and thorough instruction
BEFORE they are operated. The size, power,
complexity and operating characteristics of these types
of powered equipment would dictate that each operator
must receive adequate, professional instruction
regarding the proper operation of the Long Reach Air
Tool before being allowed to utilize it. BEFORE
attempting to utilize a Long Reach Air Tool read this
Operator's Manual and watch the applicable Safety
and Operational Information Video Tape 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 Long
Reach Air Tool. DO NOT OPERATE THE LONG
REACH AIR TOOL UNTIL EACH OPERATOR
COMPLETELY COMPREHENDS THE CONTENTS
OF THIS MANUAL, THE APPLICABLE SAFETY AND
OPERATIONAL INFORMATION VIDEO TAPE, AND
APPLICABLE SUPPLEMENTAL INFORMATION.
2) Develop a comprehensive program for the safe
operation of the Long Reach Air Tool by its owner(s)
and/or operator(s). Such a program will include, but is
not limited to: instructional requirements for operation,
applicable OSHA requirements, local laws and
regulations, job site safety and a Long Reach Air Tool
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 Long Reach Air Tool 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 Long ReachAir Tool, contact the Customer Service
Department for specific information BEFORE
utilization. There is no charge for this service.
4) Minors should never be allowed to operate the Long
Reach Air Tool. Bystanders, especially children and
animals, should not be allowed in the area where the
Long Reach Air Tool is in use. The hole digging
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 auger and/or auger extensions.
5) Operators must be in proper 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 Long
Reach Air Tool is strenuous. If you have any condition
that might be aggravated by strenuous work, check
MDF SERIES LONG REACH AIR TOOLS FORM GOM6019801, VERSION 1.0, AUTHORIZATION: DVR, PAGE: 7

with your doctor BEFORE operating the Long Reach
Air Tool. Guard against the possibility of back related
injuries. Always lift the Long Reach Air Tool with leg
muscles and not with the back.
6) Prolonged use of the Long Reach Air Tool (or other,
similar machines) exposes the operator to vibrations
which may produce Whitefinger Disease (Raynaud's
Phenomenon). This phenomenon reduces the hand's
ability to feel and regulate temperature, produces
numbness and burning sensations and may cause
nerve and circulation damage and tissue necrosis.
Antivibration systems do not guarantee that you will not
sustain Whitefinger Disease. Therefore, continuous
and regular users should closely monitor the condition
of their hands and fingers. After each period of use,
exercise to restore normal blood circulation. If any of
the symptoms appear, seek medical advice
immediately. It is recommended that special gloves,
designed to reduce the effects of Whitefinger Disease
be worn whenever possible and practical. Contact the
Customer Service Department for additional
information. There is no charge for this service.
7) Clothing must be sturdy and snug fitting, but allow
complete freedom of movement. Never wear loose
fitting jackets, scarves, neckties, jewelry, flared or
cuffed pants or anything that could become caught on
controls or moving parts. Wear long pants to protect
your legs. Protect your hands with heavy duty, nonslip
gloves to improve your grip. Good footing is most
important when operating the Long Reach Air Tool.
Wear sturdy boots with nonslip soles. Steel-toed safety
shoes are highly recommended. Keep shoes properly
laced. Never wear tennis shoes or other, similar type
shoes which afford little or no protection. Wear an
approved safety hard hat to protect the operator'(s')
head(s) where there is a danger of head injuries. Noise
generated by the Long Reach Air Tool and the actual
operating process itself can damage your hearing.
Wear approved sound barriers (ear plugs or ear
mufflers) to protect your hearing. Continuous and
regular operators should have their hearing checked
regularly.
8) Visually inspect the Long Reach Air Tool and
accessory tools for damaged or worn parts. Look for
loose and/or damaged handle grips. Check for loose
and/or broken parts. Determine that operator controls
work freely, all safety devices are operative and
information/safety decals are readable. Check to
determine that the Long Reach Air Tool and all related
accessories are in good mechanical condition
BEFORE utilization.
9) Contact appropriate representatives to determine
if/where electrical cables, gas lines and other
hazardous items are buried under the work surface
BEFORE utilization. The Long Reach Air Tool and
related accessories are not classified as being
insulated. Contact with buried electrical cables, gas
lines and other hazardous items can result in
electrocution and/or an explosion.
10) Know how the controls operate. Know how to stop
the Long Reach Air Tool quickly in an emergency.
11) Never exceed the recommended capacities of the
Long Reach Air Tool. Refer to the Specifications
section of this manual for more detailed information.
Always utilize the correct accessory tool designed for
use with the Long Reach Air Tool. Use of an incorrect
accessory tool can result in property damage and/or
personal injury.
OPERATION.
1) Give complete and undivided attention to the job at
hand. Do not chew gum, smoke and/or use smokeless
tobacco while utilizing the Long Reach Air Tool. Do not
attempt to eat and/or drink while utilizing the Long
ReachAir Tool. Determine that eyeglasses, hearing aid
devices and other medical related devices are properly
secured. Keep shoes properly laced. Use of the Long
Reach Air Tool is strenuous and causes fatigue. Help
prevent the cause of an accident. Plan to take work
breaks as required to help maintain proper mental and
physical alertness.
2) The MDF Series Long Reach Air Tools are not
sealed or insulated. Do not operate any Long Reach
Air Tool in an explosive atmosphere or near
combustible materials. Refer to current OSHA and
National Electric Code® rules and regulations.
3) The MDF Series Long ReachAir Tools are designed
for use by one operator. Use of the Long Reach Air
Tool by more then one operator can lead to confusion
and loss of control, resulting in property damage and/or
personal injury. Never operate the Long Reach Air Tool
with an improper number of operators. If it is felt that
more than one operator is required to furnish additional
"down pressure" to the accessory tool STOP and
contact the Customer Service Department for specific
operational and service/maintenance information.
There is no charge for this service.
4) Do not operate the Long Reach Air Tool with
onlookers close by. Caution all onlookers to stand

MDF SERIES LONG REACH AIR TOOLS FORM GOM6019801, VERSION 1.0, AUTHORIZATION: DVR, PAGE: 8

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 and foreign objects
clear of the accessory tool.
5) Do not utilize a shovel and/or foreign object to
remove loose material from around the work area while
the Long Reach Air Tool is in use. Such a practice can
result in the shovel and/or foreign object to become
entrapped by the accessory tool, leading to property
damage and/or personal injury.
6) Operate the Long Reach Air Tool only in a well
ventilated area. Dusts created as a by product of the
operating process can be hazardous. Breathing these
dusts can result in property damage and/or personal
injury. Operate the Long Reach Air Tool only
when/where visibility and light are adequate for the job
at hand. Work carefully. Always hold the Long Reach
Air Tool firmly with both hands. Wrap your fingers
around the barrel, keeping it cradled between your
thumbs and fingers. Always make sure the handle
grips are in good condition and free of moisture, pitch,
oil or grease. Wear gloves to improve your grip. Never
leave the Long Reach Air Tool operating unattended.
7) Stop the Long Reach Air Tool when moving it on the
job site. Allowing the Long Reach Air Tool to remain
operating while moving it substantially increases the
potential for property damage and/or personal injury.
Special care must be exercised on slippery conditions
and on difficult, uneven surfaces. Watch for cracks,
high spots and other, surface irregularities. Keep
proper footing and balance at all times. The normal use
of the Long Reach Air Tool is on level surfaces. Other
terrains can be dangerous and should be avoided.
Only properly trained operators should attempt these
techniques.
8) Because the Long Reach Air Tool is classified as a
low cost, hand held, portable type machine, it is limited
in the number of practical and/or suitable job
applications. A particular job site, actual surface
conditions, job specifications and operator
skill/common sense may dictate that a different type of
machine (with characteristics of higher purchase cost,
being mounted to a carrier vehicle, with greater
horsepower and less mobility), method and/or process
be utilized to properly complete the job with the degree
of efficiency and safety required. Contact the Customer
Service Department for specific information regarding
suitable job applications, job site surface conditions
and operator experience/skill/common sense
recommendations for the Long Reach Air Tool
BEFORE utilization. There is no charge for this service.
MAINTENANCE, REPAIR AND STORAGE.
1) Use only genuine, approved replacement parts and
accessories for maintenance and repair. Use of parts
and accessories manufactured by others can result in
property damage and/or personal injury.
2) Follow the Service instructions as outlined in the
appropriate section of this manual.
3) Always stop and disconnect the compressed air
source BEFORE checking or working on the Long
Reach Air Tool.
4) Always properly maintain the Long Reach Air Tool.
Frequently check all fasteners and individual parts.
Built in safety features are effective only if they are
maintained in good working condition. Replace any
questionable part or assembly with a genuine, factory
approved, replacement part. Do not forsake proper
maintenance for the price of a few replacement parts.
Proper maintenance does not cost...it actually pays
dividends. Do not attempt any maintenance repair
work not described in this manual. Have such work
performed at your dealer's service facility.
5) Determine the throttle control is not damaged and
allows for complete freedom of movement to allow it to
perform its intended job function. Do not operate the
Long Reach Air Tool with a damaged throttle control.
6) Maintain all safety and operation decals in proper
condition. If any decal becomes damaged and/or
unreadable, replace with a genuine, factory approved,
replacement part only.
7) The Long ReachAirTool may utilize self locking type
hexagon head nuts to minimize the effects of vibration.
Replace all self locking hardware with genuine, factory
approved, replacement parts only.
8) Replace the accessory tool when signs of excessive
wear is seen. When such components are not replaced
at proper intervals, excessive wear will occur. Utilizing
accessory tools that are past their useful service life or
that have not been properly maintained can result in
substandard productivity, excessive property damage
and/or personal injury. Accessory tool service life can
be greatly extended with a consistent maintenance
program.
