When bagging machine parts break, do you call a repairman—only to spend money and waste time? Actually, replacing easy-to-wear parts of a bagging machine is something beginners can do themselves, and it saves a lot of money. Today, we’re sharing these tips with you!

First, the sealing strip. It’s like the weatherstripping on doors and windows. When it wears out, buy one online for about $2 and install it yourself in 5 minutes—no extra tools needed.

Next, the feeding rollers. If they’re scratched, they’ll cause bagging to go off-track. First, wipe them clean and see if they still work. Don’t replace them unless you have to—avoid waste.

Then, the photoelectric sensor. If it’s dirty, it will malfunction. Wipe it with an alcohol pad, and it’ll work like new—no need to replace the whole thing.
