General Maintenance
Safety Decal Locations
Check condition of all safety decals. Replace any
decals that are missing or damaged. Clean dirt or
debris from all decals that are illegible (Figure 12).
Routine Inspection
Perform all maintenance inspections or service
requirements with the sandbagger attachment
on the ground and the host vehicle engine OFF.
Contact with moving parts can cause serious
injury or death.
Every ten hours of operation:
1.
Inspect the four belt screen shields (Figure 2).
DO NOT operate without proper shields in
place. DO NOT replace belt shields with
standard belting. Replace with factory
supplied belting only. Contact with moving
parts can cause injury. Rocks jammed or
wedged between screen due to missing belt
shields can cause damage to screens and
drive mechanism.
2. Inspect elastomer springs for looseness.
Replace if there is no preload noticeable on
springs (Figure 9). Preload is correct when
elastomer spring expands against spacer ring.
Should it be necessary to replace elastomer
springs refer to Disassembly Procedures.
It is not necessary to remove screens or
screen supports to check elastomer springs for
preload. Contact with moving parts can cause
injury, be sure equipment is OFF before
performing inspection. Preload is checked by
using a small bar between the screen and
auger flight (Figure 15).
3.
Inspect the screen support isolators. Replace
if isolators have broken or deteriorated (Figure
14).
Every 40 hours of operation:
1.
Remove motor housing inspection cover
and check motor drive mechanism for;
Leaks - tighten or repair.
Sand entry into housing - inspect for broken or
worn push rod boots or for damaged or worn
auger drive shaft seal (Figure 15).
Slack in push rod joints*
Loose shaker bearing mechanism.*
* NOTE: Contact with moving parts can cause
injury, be sure equipment is OFF before performing
inspection. Slack or looseness is checked by using
a small bar between the screen and auger flight
(Figure 15).
