REMOVE AND REPLACE EDGE RAIL CONVEYOR CHAINS AND RAILS
REMOVE CHAINS
1. At the off-load end of the oven, remove the chain guard from each rail by removing the button head
screws with a 1/8" hex key.
2. Run the conveyor until the master link for one of the chains comes up just under the rail. Remove the
master link from the chain and unthread the chain from all of the sprockets that it wraps around on its
way under the oven. Make sure that the chain is off the drive sprocket and tie-wrap it to the idler shaft
just below the end of the oven.
3. Go to the on-load end of the oven and remove the chain guards. Pull the chain out of the rail and let it
drop down. Tie wrap the end of the chain to the idler shaft below the end of the oven.
4. Repeat steps 2. and 3. to remove the chain from the remaining edge rail(s).
