Parts of the machine which should also be inspected regularly but are not exposed to
steel shot are the control panel, motor, electric cords, dust collector hose, filters, & motors.
If any of these components show signs of wear, they should be repaired so that they are
in the same working condition as when they were new. If they cannot be repaired, then
they should be replaced immediately. Prior to any repair work, secure the machine
against unintentional switching-on. Put the machine in the safety off position. The
supplier’s operating & maintenance instructions should also be followed during service &
maintenance procedures.
Blast Wheel Removal & Installation
When the blades on the blast wheel are deteriorated by 50% or more, then the blast wheel
should be replaced. To replace the blast wheel, perform the following steps:
1. Verify that the shot blasting machine is turned off & disconnected from all power
sources.
2. Remove the feed spout & the control cage.
3. Remove the four mounting nuts, flat washers, & lock washers that secure the
control cage mounting assembly to the blast housing. Do not loosen any other
screws on the control cage mounting assembly since they are used to set the gap
between the blast wheel & the control cage. Remove the control cage mounting
assembly.
4. Remove the socket head cap screw & lock washers from the blast wheel & remove
the blast wheel.
5. Check the wheel hub for wear & replace if necessary.
6. Install new blast wheel using the new socket head cap screw & lock washers that
are included in the wheel kit. Be sure that the new blast wheel is seated properly
on the wheel hub before tightening the socket head cap screw.
7. Reinstall the control cage mounting assembly to the blast housing.
8. Install the new control cage that was included with the wheel kit. Rotate the wheel
by hand to be sure that the control cage & the wheel do no touch. The initial window
setting for the control cage should be between 8:30 & 10:30.
