Make a habit of inspecting your Surface Grinder each time you use it. Check for the following con- ditions and repair or replace when necessary:
1.Loose mounting bolts.
2.Worn switch.
3.Worn or damaged cords and plugs.
4.Damaged Grinding Wheel.
5.Any other condition that could hamper the safe operation of this machine.
Table
The table and other non-painted surfaces on the Model G5963 should be protected against rust and pitting. Wiping the table surface with a slight- ly oily rag will protect bare metal surfaces from moisture.
Periodically lift the sliding table off of the ways and make sure the V-grooves and the helical gear underneath are free of debris and metal dust. Wipe the V-grooves of the table and the saddle down with way oil (Mobil Vactra #2 or equivalent) prior to reassembly.
The grinding wheel should be inspected before every use. Use the ring check method noted in the Grinding Wheel section in Operations to veri- fy the structural integrity. If using coolant during grinding, always run the wheel for 5-10 minutes at the end of the operation to remove any coolant from the wheel. Take care in storing grinding wheels to keep them free from potential damage by being dropped, or having other items drop on them.
Lubrication
Besides the one-shot lubrication system, the Model G5963 features factory-sealed bearings. A sealed bearing requires no lubrication during its lifetime. Should a bearing fail, your surface grinder will probably develop a noticeable rumble, which will increase when the machine is put under load. If allowed to get worse, overheating of the journal containing the bad bearing could occur. If the bad bearing is not replaced, it will eventually seize - possibly doing damage to other parts of the machine. Bearings are standard sizes and can be replaced through Grizzly.
