PNEG-720-G2 12" and 16" Series II Sweep 87
Is there any maintenance I need to perform on the electrical system?
None of the electrical components require maintenance. Be sure to disconnect and lock out the power
before servicing the equipment, entering the bin or resetting the motor overloads.
Does any part of the Series II Sweep need lubrication?
The fluid level of each of the gear reducers must be checked before operation. These reducers may
have been shipped dry and require oil before operation.
A complete lubrication section is provided in the Owner’s Manual, which shows the type and amount of
lubricant to be used and which components need to be lubricated.
What maintenance should I perform and how often?
Follow the lubrication instructions in the Owner’s Manual. Also visually inspect the sweep before
operation.
What should I visually inspect?
Starting from the drive end of the sweep:
Inspect the head jack, caster mounting channel and head casters. Look for any bent or damaged
components.
Inspect the motor covers. They should be in good shape and should be used properly. If the covers are
not used, the material will work its way into the motor cooling slots and when the sweep is started, the
motor fan and housing will be destroyed.
Inspect the belt guard for damage. Make sure there is no material inside the belt guard. The drain pan
at the bottom of the guard can be used if required.
Inspect the drive belts, sheaves and bushings. Check the belts for proper tension. Sheaves and
bushings should be tight.
Inspect the intermediate jacks for any broken or damaged components. Check the jack wheels for
damage. The jacks should operate freely.
Inspect each of the screw flight bearings and hangers for damage. Check to see if the bearings need to
be replaced. All hardware should be tight.
Inspect the screw flights for damage or excessive wear. Check to see if the screws are rusted or pitted.
Inspect the end bearing for damage.
Inspect the end caster (if one was originally supplied) to confirm it is working properly or if it needs to
be replaced.
Inspect the tractor drive chain guard for damage. Make sure there is no material (grain) inside the
chain guard. If there is any material (grain), drain pan which is at the bottom of the guard can be
used to empty the guard.
Inspect the drive chain for damage and proper lubrication. Check for proper tension and confirm the
sprockets and bushings are tight.
Inspect the tractor drive tires for damage or tread wear. Be sure the lug nuts are tight and tires are
installed with the tread direction as shown in the manual.
Inspect the bearings for damage or excessive wear. Replace if necessary.
Inspect the tractor drive motor and gear reducer for damage or excessive wear.
Make sure all hardware is tight.
Inspect the sweep structure for damaged or bent components.
