5) Replace Hose only when it stops heating
6) Replace In-Line Filters after 150 Hours
7) Replace Gun Head only when it stops heating
8) Change Module Every 1,000 Hours
9) Replace Nozzle Every 120 Hours

First and foremost, your melter adhesive filter should be flushed once a day. Cleaning your melter filter can be dangerous so always remember to wear safety glasses and heavy duty gloves. This will help to prevent any injuries that might be caused by splashing hot melt adhesive during the flushing process.
The first thing you must do is heat your system to its operating temperature. This is very important to prevent damage to the filter screen. Next, you will need to reduce your pump air pressure to zero at the air regulator. Then, you must relieve the system pressure by triggering any and all guns. This will now relieve trapped hydraulic pressure. After all system pressure is released, you can open the manifold drain valve. Using a screwdriver, open the valve over an open container. You then want to slightly increase pump pressure until a steady flow of adhesive comes from the drain. Continue to allow material to flow until it appears clean and free from any foreign matter. Once the adhesive appears to be clear, shut off the air pressure to the pump and close the manifold drain valve. You now have successfully cleaned your melter filter.
The importance of a clean filter when operating your melter system is imperative to running a high-quality machine. Many people wonder if they should clean their filters or if they should buy new. The easiest way to tell if your filter should be replaced is if you have used it for longer than 200 hours. Every high-quality filter, even when cleaned daily, will only last up to 200 hours of operating time.
If you do need to replace your filter please follow the below steps.
- Heat the system to operating temperature.
- Reduce your pump air pressure to zero and trigger all guns to relieve trapped hydraulic pressure.
- Loosen the filter with a socket type wrench.
- Wearing Kevlar gloves, carefully pull the filter assembly out of the manifold.
- Remove the screw in the back of the filter assembly and discard the filter screen.
- Replace the filter screen and reinstall screw.
- Inspect o-rings for damage and replace if necessary.
- Slide the filter assembly back into the manifold and tighten until it seats.
Make sure that you purge the manifold by opening the drain valve and increasing the pump air pressure slightly until a steady flow of hot melt is released from the drain. Close the drain valve and your machine is ready to operate with your new filter.

Hot melt systems are an important investment that will increase the efficiency of your business. Like with any important investment, you want to protect it and get the most out of it. A consistent preventative maintenance program is the key to ensuring efficient productivity and increasing the life of the system.
As with any product used daily, normal wear and tear can cause reduced efficiency. Over time hot melt systems naturally see decreased bead accuracy and restricted adhesive flow. By checking the system and cleaning regularly, you are more likely to maximize productivity.
INCREASED MACHINE LIFE
The more comprehensive your maintenance plan, the longer your system will last. You will get the most for your money by responding immediately to slowed pump strokes, pneumatic gun misfires, and clogged nozzles.
SAVE TIME AND MONEY
A rule of thumb is to replace any component $100 or less, instead of trying to troubleshoot the component and fix it. Studies continue to show that a company saves the most by focusing on troubleshooting and fixing the most costly equipment.
LIMIT DOWN TIME
Replace consumable parts on a regular schedule to avoid unplanned down time. Once a packaging line goes down the average cost/lost to a company is $10,000.00 per hour.
To help you, here are some standard maintenance tips to ensure you get the most out of your melter.
1. Clean and purge your hot melt unit every 500 hours and/or each time you change adhesives.
2. Check all fastenings and hose fittings to your machine and make sure they are secure and tight.
3. Clean attached components monthly.
