SAFETY PRECAUTIONS
DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV #4 (05/28/09) PAGE 11
GRINDER. Guide against the possibility of back
related injuries. Always lift the SURFACE
GRINDER with leg muscles and not with the
back.
6) Prolonged use of the SURFACE GRINDER (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.
Anti-vibration 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 circul
ation. If any of the symptoms
appear, seek medical advice immediately.
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, non-slip
gloves to improve your grip. Good footing is
most important when operating the SURFACE
GRINDER. Wear sturdy boots with non-slip
soles. Steel-toed safety shoes are highly
recommended. 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
engine of the SURFACE GRINDER and the
actual 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 SURFACE GRINDER,
components, tools and accessories for damaged
or worn parts. BEFORE each use:
a) Disconnect the engine spark plug wire or
power source cable.
b) Clean and remove all accumulated foreign
matter from the wheels and determine that
each rotates freely.
c) Clean a
nd remove all accumulated foreign
matter from inside the mainframe area.
d) Inspect the V-belt drive for proper tension,
wear and general condition. Replace each
component as necessary.
e) Inspect the multi-accessory discs and
gimbal head assemblies for excessive wear
and structural integrity. Replace each
component as necessary. The multi-
accessory discs rotating at high speed
during the specific process can be subject to
high wear rates if the installed attachment is
not properly maintained and/or replaced at
regular service interva
ls.
f) Determine that operator controls work freely,
all safety devices are operative and
information decals are readable.
g) Check to see that the SURFACE GRINDER
and all related accessories are in good,
mechanical condition BEFORE utilization.
h) Reconnect the spark plug wire or power
source cable as applicable.
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
SURFACE GRINDER and related
accessories
are not 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 engine or electrical motor quickly in an
emergency. Always start the engine or electric
motor according to the instructions as outlined in
this manual to minimize the possibility of
unexpected contact with the work surface.
Unexpected contact with the work surface can
cause loss of machine control, and the
possibility of property damage and/or personal
injury.
11. Ground the DFG20E or DFG30E electrically
powered SURFACE GRINDER motors securely.
Determine that any "grounding" wire and/or
device is, in fact, properly grounding the motor.
Failure to properly ground the motor m
ay cause
an electrical shock and/or electrocution,
resulting in property damage and personal,
injury including death. Electrical wiring and all
connections should be performed by a qualified
electrician. Depending upon the wiring
configuration, the electric motor is designed to
operate from either 115 or 230 volt, AC power
sources. Determine that the electric motor
voltage switch is properly selected according to
the intended and/or available power source.
Operating the electric motor from an improper
voltage/amperage power source can result in
property damage and/or personal injury.
