Daily Shutdown

When you are through using the MD2 valve, the outlet to

the mixer should be cleaned and protected from dr ying

or crystallization.

1. Remove and properly dispose of the static mixer.

2. Dispense a shot of material into a waste container

to clear any crossover in the nosepiece.

3. Wipe the nose with a clean rag being careful not to

let the materials contact each other.

4. Install the PTFE night cap (1:1 valves - 15K652,

10:1 valves - 15K628) and retaining nut (15K688).

Preventive Maintenance

There is a grease filled secondary seal/bearing area on

each valve shaft. Every 10,000 cycles, or twice each

month, new grease should be flushed across this area.

To grease the valve:

1. Remove the zerk grease fitting from each side of the

front or back of the valve.

2. Pump grease (115982) with grease gun (117792)

across the valve until clean grease comes out of the

other side.

3. Reinstall the zerk grease fitting.
