CAUTION

A damaged pressure control can cause poor sprayer performance and may damage other parts of the sprayer damaging the pressure control.

Use a nylon spray hose (99) that is at least 15 m (50 feet) long.

Never use a wire braid hose. It is too rigid to absorb the pulsations of the fluid in the hose.

Never install a shutoff device between the fluid filter and the main hose. See Ref. B in Fig. 1.

The motor operates and the pump strokes, but the fluid output is low or there is no fluid output.

Check to see if the spray tip is worn.

Check the motor brushes for these problems: Loose electrical leads or terminals, a brush which is worn to less than 10 mm long, a broken or misaligned spring, brushes which are binding in their holders. Refer to page 12.

Check the armature of the motor for electrical shorts by using an armature tester (growler).

Check to see if the pump continues to stroke when the gun trigger is released.

Check to see if the intake valve ball and the piston ball are seating properly

Check for leaks around the throat packing nut which may indicate that the packings are worn or damaged.

NOTE:

Replace the brushes when they have worn to about 10 mm in length. Always check both of the brushes. A Brush Repair Kit, part number 222–157, and a new spring clip, part number 110–816, may be purchased separately

NOTE: The replacement brushes may last only half as long as the original brushes. To maximize the life of the brushes, allowing

Remove the hose (47).

Remove the intake screen (99).

Push the retaining spring (35) up and push out the pin (20).

Installing the pump

Screw the pump into the bearing housing (27) until the pin holes in the connecting rod assembly (29) and the displacement rod (224) are aligned. Install the pin (20).

Continue to screw the pump into the bearing hous ing until the top threads of the pump cylinder are even with the face of the bearing housing and the pump outlet faces straight back.
