Warning: Always relieve hydraulic pressure before disconnecting any hydraulic fitting or opening any pressurized port.

Press the Pump key to stop the pump.

Trigger the guns until hot melt no longer flows from the guns.

Use an 8 mm (5/16-inch) hex-head wrench or an adjustable wrench to loosen (counterclockwise) and then remove the filter.

Properly dispose of the old filter.

Confirm that the O-ring on the new filter is in good condition (100-mesh filter is P/N 1028305).

Note: 50- and 150-mesh filters are also available (P/Ns 1021941 and 1034720).

Screw the filter into the pump body and then tighten the filter to 4.5 N•m (40 in.-lb).

To avoid the problems that can occur when different hot melt materials are mixed or when hot melt char forms in the tank, clean the tank when:

- changing to a different type of hot melt

- excessive char builds up inside the tank

NOTE: The tank cleaning procedures provided in this section require that an appropriate flushing material be used.; The flushing material should be compatible with both the previous adhesive and the new adhesive, if applicable.

To clean the tank when changing hot melt

1. Operate the melter normally until the tank is empty.

2. Press the Pump key to stop the pump.

3. Allow the melter to heat or cool to the temperature recommended by the manufacturer of the flushing material.

4. While wearing the appropriate protective equipment, wipe any residual hot melt from the inside of the tank.

To prevent components from overheating due to heat build-up or loss of air circulation, regularly remove any hot melt that collects on the exterior of the melter, hoses, and guns.

If hot melt inadvertently spills inside the melter’s interior spaces, the side panels can be removed in order to clean out the spilled hot melt.

WARNING: Risk of electricution and fire! Do not clean the melter with a direct stream of water or steam.; Use only water or an appropriate, non-flammable cleaning solution that is applied using a clean cloth.

Cleaning the melter using a direct stream of water or steam or a flammable solvent can result in property damage and personal injury, including death.

To clean the exterior of the melter:

- Use only cleaning compounds that are compatible with polyester.

- Apply cleaning compounds using a soft cloth.

- Do not use pointed or sharp tools to clean the exterior surface.;

Warning: De-energize the melter before starting the procedure. Refer to Section 1, Safety.
