Repair

Pressure Relief Procedure

Trapped pressure can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

1. Engage the trigger lock.

2. Shutoff the pump:

a. For air-powered pumps, close the bleed-type

master air valve.

b. For hydraulic-powered pumps, close the supply

line shutoff valve first, then close the return line shutoff valve.

3. Disengage the trigger lock.

4. Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.

5. Engage the trigger lock.

6. Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

Disassembly

Lay out all the removed parts in sequence, to ease reassembly.

Packing Repair Kits are available. For the best results, use all the new parts in the kit. Kit parts are marked with an asterisk, for example (3*). These kits can also be used to convert the lower to different packing materials. See pages 14-17.

1. Flush the pump, if possible. Stop the pump at the bottom of its stroke. Relieve the pressure, page 5.

2. Disconnect the lower from the motor. See your separate pump assembly manual.

3. Place the lower lengthwise in a large vise, with the jaws on the outlet housing (7) as shown in F on the cylinder (8) flats. Loosen, but do not remove, the packing nut (2).

4. Unscrew the intake valve (18). Be careful to catch the intake ball (17) as you remove the intake valve so it does not fall and suffer damage. Remove the seal (30). Inspect the ball and seat (D) for wear or damage.

IG. 1, or

7. If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.
