Grizzly G9928 instruction manual Maintenance, Carbon Brush Replacement, Lubricating Flex Shaft

MAINTENANCE

!

Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious person- al injury.

CARBON BRUSH REPLACEMENT

Normal Carbon Brush life is 500–2000 hours, depending on use. Always replace both brushes when it is time for replace- ment.

1.Use a small screwdriver and remove the Carbon Brushes from the sides of the Motor Housing. Be careful when removing the brushes, as the brushes are spring-loaded and may spring out. If the brush does not spring out, gently remove it using the tip of the screw- driver. Examine the brush surface for scratches or breakage. If the brush is broken, replace immediately with a replacement brush from Grizzly Industrial, Inc.

2.If the brush is not broken and is dirty, remove the dirt using a pencil eraser. Gently rub with the eraser until all of the dirt has been removed. Remove all eraser dust so it will not interfere with the machine.

3.Reinstall the brushes and gently tight- en with the screwdriver.

LUBRICATING FLEX SHAFT

The Flex Shaft and Flex Shaft Housing should be lubricated after every 8 hours of use. A small amount of light lithium lubri- cant or machine oil applied to the length of the Flex Shaft is all that is needed. Too much lubricant can become messy and possibly get on your workpiece. Do not use automotive grease as it is too vis- cous.
