The service information is intended for use by a service technician who is familiar with proper and safe procedures to be followed when repairing electrical appliances and who is equipped with proper tools and testing devices. Repairs attempted or made improperly can result in personal injury or property damage. Hazards may develop from improper assembly or adjustments. While making repairs, persons not having the proper background may subject themselves to the risk of injury or electrical shock which can be serious or even fatal.
IMPORTANT - NOTE TO THE CONSUMER
If you perform service on your own Broan products, you must assume responsibility for personal injury or property damage which may result.
The specification label with model and serial numbers is located on the inside of the cabinet. It is visible after opening the drawer.
DO NOT use plastic bags other than those which have been designed for use in this compactor. Unauthorized bags may become caught in the mechanism.
With the drawer extended to the second stop, release the container latch and swing open door. Slide bag into drawer from front to back. Fold bag over top rim of drawer on all sides.
Press bag into all corners of the drawer. Smooth and shape the bag carefully - this will prevent the bag from being torn by the ram during compaction.
When transporting compactor, the ram should be electrically or
manually extended down into the drawer, preferably against a
load of stacked newspapers or other suitable material. If this is
not done, damage to the trunnion nut may occur.
Never transport compactor on its back or front. Damage to the
gearbox may occur. If it cannot be transported upright, it is

1.Remove motor, gearbox, spocket, and screw guard.
2.Use 13/16" wrench to remove bolts securing links to motor trunnion.
When reinstalling, bolts torque to 45 foot pounds.
1.Line up one of the 3/8" holes in the sprocket with the 3/8" hole in bottom center of gearbox. Insert 3/8" steel pin or bolt through sprocket hole into front and rear gearbox holes.*
2.Loosen and remove 15/16" nut on the drive screw. When reinstalling torque to 65 foot pounds and apply Locktite® to threads.
*If the sprocket is too damaged to be able to use on of the holes to secure it, chip away the remaining sprocket, remove the drive pin and then insert a screwdriver through the hole to provide a means of keeping the drive screw from turning.
1.Turn sprocket until two holes in sprocket line up with socket head cap screws.
2.Remove socket head cap screws and tip gearbox/motor assembly to remove chain. NOTE: The screws thread into 2 nuts which rest in slots in the motor trunnion. Be careful not to lose the 2 nuts when the screws are removed.
When reinstalling socket head cap screws, be sure Locktite® is applied to the nuts.
Chain Derailment: Loose chains. Sometimes a chain will derail because trash which flew up above the ram during compacting fouled the chain. Newspaper or a paper bag should be placed on top of glass bottles before compacting to prevent this.
If continual derailment of the chain is a problem, inspect both sprockets for worn or missing teeth.
Inspect gearbox mounting and mounting plate. If the mounting screws are loose, gearbox movement may be the cause. If the gearbox mounting plate is bent where it meets the motor trunnion,eitherstraightenorreplace the gearbox.
Somechainloosenessisnormal and may increase as the compactor is used. Seldom does the chain “stretch” to the point where it is too loose.
