As with all machinery, proper attention and
maintenance is the key to long component life,
maximum performance, and safe operation. By
spending a few minutes reading and following these
preventive measures, you should reduce the downtime
and prolong the life of your system.
It is important to understand that these maintenance
schedules are minimum recommendations. Anyone
who maintains or services a stretch wrap machine
must first satisfy himself/herself as to the schedules of
preventive maintenance based on cycling operation
and environmental locations.
WARNING! All maintenance operations require
the equipment to be powered down and
locked out for personnel safety.
LOCK-OUT/ TAG-OUT PROCEDURES
Be sure that anyone performing any type of
maintenance on this equipment is familiar with and is
adhering to the lock-out/tag-out procedures set forth by
the General OSHA or the State OSHA guidelines.
VISUAL CHECKS
Visual checks should be conducted at least once per
month:
1. Keep the machine and surrounding area as clean
as possible, especially near moving components.
2. Check for loose hardware, especially set screws
located in: sprocket hubs, bearing hubs, and
flanges.
3. Check for oil leaks around the speed reducers.
4. Check for dry seals at the bearings.
5. Check for chain wear and proper tension on the
power roller stretch sprockets. The correct amount of
chain tension can be checked by pulling the chain
taut and having 3/8" slack.
6. Check for loose electrical connections and for
frayed cords and cables. Replace immediately any
damaged cords and cables.

MAINTENANCE
TURNTABLE BELT ADJUSTMENT

loosen the four motor flange (M10) screws. Turn the
(M10) bolt on the adjuster tab until the belt is tensioned.
Retighten the four motor flange screws.

FILM CARRIAGE LIFT CHAIN ADJUSTMENT
Refer to figure below to adjust the film carriage lift
chain. First, loosen nut (M12) on the adjustment bracket.
Turn the bottom bolt until desired tension is achieved.
Retighten nut (M12). Note that the driving chain
and adjustment bracket should be parallel with the
moveable pulley base.
SPROCKET AND CHAINS
All sprockets should be inspected for wear, and chains
should be checked for proper tension and lubrication
on a periodic basis. Failure to do so will lead to
premature sprocket failure. Any general-purpose chain
lube should be sufficient for lubrication. Replace chain
guards when preventative maintenance is complete.
