Checking and Replacing the Diaphragm
Note! It may be necessary to bleed the sprayer after changing the diaphragm, see
"pressure relief procedure".
Please follow these steps;
1. Remove the 4 bolts (A) on the manifold.
2. Remove the manifold and set aside.
3. Remove the diaphragm (B) by lifting an edge and working it out, away from the housing.
4. Insert the new diaphragm and repeat the above in reverse order.
Transporting/Storage
1. Clean the machine and spray system.
2. Switch the machine ON for a few seconds and press the spray gun trigger until any fluid remaining
in the machine is ejected, then switch OFF immediately.
3. Disconnect the high pressure hose and spray gun connections.
4. Store the machine and accessories in a place that does not reach freezing temperatures or near
regular heat sources as it may dry the pump seals. Do not allow high pressure hoses or tubes to
become kinked or pinched when storing.
