Stow SFG10E manual Safety Precautions

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 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 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 disc and gimbal head assembly for excessive wear and structural integrity. Replace each component as necessary. The multi-accessory disc 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 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

SAFETY PRECAUTIONS

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 electric motor quickly in an emergency. Always start the 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 electrically powered SURFACE GRINDER motor 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. The electric motor is designed to operate from a 115 AC power source.

12)When operating the SURFACE GRINDERs on a surface containing water or other electrically conducting liquid, special precautions must be taken to minimize the possibility of operator electrocution. Once such precaution is to wire and operate the electric motor from a clean, 20 Ampere, 115 Volt AC power source in conjunction with a ground fault circuit interrupter (GFCI). A GFCI is a safety device that disconnects power from a circuit to a load when a potentially dangerous condition occurs. The GFCI opens the circuit when the fault current flow from a power line to a ground exceeds the safe limit for humans.

The GFCI protects against harmful electrical shock to a person caused by contact with a defective electrical product. A GFCI differs from a fuse or circuit breaker. A fuse or circuit breaker opens the circuit when the total current flow in the power line exceeds the safe limit of the power line. They are designed to protect against fire caused by overheating of the power line. Use of a GFCI gives on the job protection from electrical shock hazards caused by ground faults in commercial, industrial and residential applications.They are simple and easy to use: plug a portable GFCI into any suitable, grounded extension cord and plug the SURFACE GRINDER into the GFCI for automatic protection against ground faults.

For specific information, consult current National Electrical Code® publications and OSHA publications 210-22D (or current revision) for construction sites and 555-3 (or current revision) for use around any area containing water.

13)Never exceed the recommended capacities of the SURFACE GRINDER. Refer to the Specifications sections of this manual for more detailed information
