MAINTENANCE
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.
REPLACEMENT ACCESSORIES
Should you need to order replacement
parts for your Model G9928, please refer
to the following parts diagram and list.
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.
Disconnect power to the machine
when performing any maintenance,
assembly or adjustments. Failure to
do this may result in serious person-
al injury.
