Operational Tips - Grizzly G0767Z Owner's Manual

Adjusting Abrasive Belt Tracking
Adjustments to the abrasive belt tracking are
made with the machine running. These adjust-
ments are made in small amounts to make sure
the belt does not track too far from the center,
which could damage the belt and machine.
To adjust abrasive belt tracking:
1. Make sure belt and deburring station covers
are closed and secured.
2. Have another person position his hand
over emergency stop button to quickly
turn machine OFF and prevent damage if
abrasive belt moves too close to side of
machine.
3. Connect machine to power, turn it ON, and
observe to which side abrasive belt tracks.
— If abrasive belt tracks to the left (as viewed
from front of machine), rotate tracking
adjustment cap screw (see Figure 27)
counterclockwise in small amounts until
abrasive belt tracks in center.

Operational Tips

• Hot particles flying off of abrasive belt travel
very fast—prepare for this! Wear proper per-
sonal protective equipment.
• Grinding metal produces flying sparks. DO
NOT allow anyone to stand in path of sparks.
DO NOT grind near flammable materials or
combustible fumes.
• When grinding against the profile roller, make
sure all covers are closed securely and spark
shield is properly positioned.
• Use multiple light passes instead of a few
heavy passes to increase the life of abrasive
belt and decrease the need to deburr along
notch edges.
• Make sure the tube is firmly secured in the
vise and any tube longer than 3' is supported
at the opposite end by another person.
• Tube will get hot as you continue grinding
operations. Cool it frequently by quenching in
water or quenching salt solution.
• Change belts frequently and use the correct
grit for best performance.
• DO NOT force or jam tube into abrasive belt.
• When deburring, hold tube securely with both
hands. Use rest when possible to support the
tube.
• Concentrate on task at hand. STOP grinding
if you become distracted.
• When not in use, release abrasive belt
tension to increase life of belt.
