Goff 2460, Operation And Maintenance Manual

SUGGESTED MAINTENANCE SCHEDULE
1.
Blast Wheel Wear Parts
- Inspect Daily
Replace when wear parts are deeply grooved or worn to half original thickness.
2. Blast Wheel
- Balance & Noise - Daily
Testing for balance is done by running the blast wheel with the blades in position and
then without blades. A vibrating wheel indicates improper balance or possible motor
failure.
3. Blast Pattern
- Weekly
If improperly directed the blast pattern will cause an increase in blast time as well as
abnormal wear on the equipment. The blast pattern should always be checked after blade
replacement or any change in abrasive being used.
4. Fans
&
Motors
- Monthly
Check for proper rotation. Improper rotation could cause a loss in power or severe
damage to motor or machine. Keep motors free of oil, dust, dirt, water and chemicals as
much as possible. Inspect motor bearings and lubricate when necessary. BE CAREFUL
NOT TO OVER LUBRICATE. The greatest cause of motor bearing failure is over
greasing not under greasing.
5.
Screens
- Daily
A hole in the abrasive screen could allow large materials to re-circulate and reach the
blast wheel causing severe damage.
6. Roller Chain and Sprockets
- Inspect Monthly
Maintain light film of oil - Replace when stretched beyond "take-up". Replace sprockets
when teeth are worn.
7.
Separator Air Flow
- Daily
This is done by inspecting the abrasive. If it is dirty or dusty, increase the air. Dirt and
dust allowed to build up in the abrasive will use up power in the blast wheel causing a
decrease in cleaning quality.
8. Elevator Belts, Buckets and Pulleys
- Inspect Weekly
Replace belts when worn and/or frayed or when stretched to point where belt will not
"take-up" or will not track.
Replace buckets when cracked or worn where 60% capacity cannot be held. Replace
pulleys when lagging is worn
9.
Dust Collector
- Daily
Inspect fan, blower, duct work, housing and filters. Improper operation of the dust
collector causes a build up of dust on the working parts of the machine and causes work
environment hazards. Refuse from the dust collector should be inspected daily for any
traces of good usable abrasive. The dust collector should keep machine dustless but
should not draw out any usable abrasives.
