SAFETY AND OPERATING GUIDELINES (continued)
• Turn the wheel off if it jams. A wheel jams when it digs too deeply into the tungsten (the motor force keeps it stuck in
the tungsten).
• Never stand or lean on the grinder. Serious injury could occur if the grinder is tipped or if the cutting tool is
unintentionally contacted.
• Keep hands away from moving parts and cutting surfaces.
6. MAINTENANCE
• Always unplug grinder before inspection.
• Keep the grinder clean for safest operation
• Remove adjusting keys and wrenches. Form a habit of checking that keys and adjusting wrenches are removed
before the grinder is turned on.
• Keep all safety guards in place and in good working order.
• Keep all parts in working
order. Check to determine that the guard or other parts will operate properly and
perform their intended functions.
• Check for damaged parts and alignment of moving parts, binding of moving parts, breakage of mounting parts
and any other condition that may affect the grinders operation. Consult DGP factory for replacement parts

• Do not use power tools in dangerous environments, such as damp or wet locations. Do not expose power tools
to rain.
• Work area should be properly lighted.
• The proper electrical outlet should be available for the tool. For 110V, a three prong plug should be plugged
directly into a three prong outlet and /or extension cord.
• Keep visitors a safe distance from work area and keep children out of work place. Use padlocks or master switches to
prevent any unintentional use of power tools.
