card and operating manual.

SAlways follow instructions in the material supplier’s

Material Safety Data Sheet (MSDS) or material

information sheet.

SEven 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.

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: Risk of electrical shock. Failure to

observe may result in personal injury or death.

WARNING: Disconnect equipment from line

voltage.

WARNING: Hot! Risk of burns. Wear

heat-protective clothing, safety goggles, and/or

heat-protective gloves depending on the symbol or

symbols shown.

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

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.
