MAINTENANCE

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.

TURNTABLE BELT ADJUSTMENT

Refer to figure below to adjust the turntable belt. First, 

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.
