SAFETY PRECAUTIONS

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 circulation. 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 and 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 intervals.

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 may 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.
