Grinder should Be Maintained properly
• 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
at: (805) 498-3837.
Work area should Be ready for the Job
• Keep work area clean.
• 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, master
switches, and remove starter keys to prevent any unintentional use of power tools.
