IX. MAINTENANCE (Continued)

C. GEAR BOX

The gear box contains the worm-and-pinion gear that transmits power to both the 41/2" and 10" wheels. The gears should be lubricated with a light gear grease after every 300 hours of use. Inspect the gears for wear or damage during each lubrication. To lubricate:

1.Remove gearbox cover. Figure 7.

2.Apply a light coating of grease to the gears.

3.Re-attach cover.

Figure 7. Gear Box cover removed.

The motor of the Slow-Speed Grinder operates at high speeds. DO NOT attempt to inspect or lubricate the gears while the machine is running. Turn off the machine and disconnect it from its power source before servicing. Failure to do so could result in serious personal injury.

D. WATER RESERVOIR

A constant supply of water is essential for optimum 10" wheel performance. Change the water

in the reservoir once a week to avoid clogging the aluminum oxide wheel. A drain plug at the bottom of the reservoir can be removed to flush out the reservoir and remove sediment. Figure 8.

Drain

DO NOT attempt to use the 10" grinding wheel without filling the reservoir with water. Overheating caused by lack of lubrication could damage the grinding wheel, as well as the tool or blade you are grinding. Ensure that the reservoir is filled with clean water. Sediment-filled water can clog the wheel and lessen the grinder’s ability to work effectively.

DO NOT allow the grinding wheel to stay immersed in water for long periods of time without running. The water can cause the wheel to become waterlogged and unbalanced and may cause sections of the wheel to break off when the wheel is started. Always drain the reservoir when the grinder will not be used. Serious personal injury may occur.
