The pump is serviced, tested and ready for use. Nevertheless, before starting the sprayer,
we advise checking the oil level.
The oil level should be filled to the mark on the plastic tube.
When adding oil, remove cap and fill to level mark with SAE 30 weight engine oil.
CHANGING THE OIL
1. Remove the pump and drain the oil by turning the pump upside down. To do
this remove the filler cap and turn the P.T.O. shaft by hand.
2. Fill the crankcase with mineral (flushing) oil to wash all internal parts. Then
drain pump again.
3. Add new oil and at the same time turn the P.T.O. shaft by hand. When the
correct oil level has been reached, continue to turn the shaft until all the air
bubbles in the oil have disappeared.
DIAPHRAGM AND VALVE REPLACEMENT
I.
Valve & O-ring Replacement
1. Occasionally debris can cause the valves to not seat properly or damage
the o-rings. To check for this problem, follow these steps:
a. Remove the check valve manifold. (See parts list for your model.)
b. With manifold removed, valves can readily be removed and checked
for debris or wear.
To replace valves or o-rings, refer to parts list for appropriate kits.
II.
Diaphragm Replacement
1. Drain the oil from the pump. Rotate the shaft to remove excess oil.
2. Remove the pump heads.
3. Use a box wrench to remove the diaphragm retaining bolt, support
washer and diaphragm.
(
To replace diaphragms order appropriate repair kit. See parts list.)
4. Turn the crankshaft to bring the piston to its downstroke and seat the new
diaphragm into the sleeve groove. Install retaining washer and tighten bolt.
5. Refill crankcase with 30 weight oil. Rotate the shaft to distribute oil and fill
to proper level.
