Maintenance

stop spraying or dispensing and before cleaning,
checking, servicing, or transporting equipment.

Clean Static Mixers

See F . 1 on page 9. Typically, two static mixer
IG

These housings use plastic mix elements, available in a
package of 25 (Part No. 248927).

union will compress the tube and make it
impossible to remove the mix element.

2. Remove mixer housings (J) from whip hose (K).
3. Place flats of mixer housing (J) in a vise. Push mix
element (P) out of the inlet end.
4. If necessary, use a 1/2 in. drill bit to drill out old
material and the mix element from the inlet end,
down to the internal shoulder at the outlet end.
