Series 3500/3700 Hot Melt Material Applicator
Please Note
The operator’s card contains only information necessary for daily operation and maintenance. For other information, refer to the product manual.
A copy of this operator’s card and an order form for another operator’s card are included in the Introduction part of the operating manual.
WARNING: Allow only qualified personnel to operate and maintain the unit. Observe the safety instructions in the operating manual and the safety symbols.
Safety Symbols
The following symbols warn against dangers or possible sources of danger. Become familiar with them! Failure to heed a warning symbol could lead to personal injury and/or damage to the unit or other equipment.
WARNING: Failure to observe may result in personal injury, death, or equipment damage.
WARNING: Risk of electrical shock. Failure to observe may result in personal injury or death.
S Always follow the instructions given in the operator’s
card and operating manual.
S Always follow instructions in the material supplier’s
Material Safety Data Sheet (MSDS) or material information sheet.
S Even at recommended operating temperatures, hot
melt material may release vapors. Exceeding prescribed processing temperatures for long periods of time can result in dangerous decomposition by-products. Remove vapors by drawing them off with an exhaust system.
WARNING: Hot! Risk of burns. Wear heat-protective clothing, safety goggles, and/or heat-protective gloves depending on the symbol or symbols shown.
WARNING: Pressurized system or material. Release pressure. Failure to observe may result in serious burns.
WARNING: Disconnect equipment from line voltage.

25 mm 50%
Startup
1. Check the adhesive level. Add adhesive to tank if the level is below 50% of its holding capacity. Fill to within 25 mm (1 inch) of tank top.
2. Close the lid immediately to prevent contamination of the adhesive.
3. Set the circuit breaker to ON. Refer to “Overview of System Components,” item 2.
4. Check the temperature settings for all zones (channels).
5. Wait for “System Ready” indicator to become illuminated.

Daily Startup/Shutdown
Startup (contd.)
6. Set the air pressure controls for the proper pump and gun pressure.
7. Proceed with normal operation.
8. Check the adhesive level periodically. Refill the tank before the level drops below 50% of its holding capacity.
WARNING: When the tank lid is open, hot melt vapors may be released.
Shutdown
1. Reduce the pump air pressure to “0.”
2. Trigger all guns to relieve trapped hydraulic pressure.
3. Set the circuit breaker to OFF.
4. To prevent accidental gun triggering: a) Reduce automatic gun air pressure to “0” or; b) Place the trigger safety on manual guns to the locked position.
WARNING: Never hang a handgun by its trigger. The gun can accidentally discharge material, resulting in burns.
Daily Maintenance
1. Clean the exterior surfaces of the applicator and guns.
2. Check the o-rings and gaskets for leaks.
3. Flush the manifold filter. a. Reduce the pump air pressure to “0.” b. Trigger all guns to relieve trapped hydraulic
pressure.
c. Turn the filter assembly center screw to DRAIN
(CW).
d. Open the left side drain valve over a container
(CCW).
e. Increase the pump air pressure until a clean
steady flow of hot melt material flows from the
drain. f. Close the drain valve. g. Reduce the pump air pressure to “0” and repeat
the procedure for the right side drain valve.
