4. For safe operation

5. Set up

Hose clamps are not completely tight.
Please tighten hose clamps prior to using.
Hose clamps are left loose to extend life of gaskets and
fittings.

Oil cap gasket before using and lubricate weekly so the
gasket will seal properly and prevent chemical leaks.

Oil check valve and maintain breather hole clear of
debris. Your failure to oil may can cause the tank to
collapse and crack due to vacuum created by pump
lubricate with "3 and 1" oil.

Make sure to insert the locking pin for the pump handle in its
(only) CORRECT POSITION.

The pin limits the pump stroke for optimum performance
without see page. Observe Fig. 1 exactly. (Fig. 2 and 3 spell
trouble.)

For best results and to maintain a good seal, re-grease piston
sleeve periodically with vaseline or similar light lubricants.

HOW TO ASSEMBLE

1. Attach spray wand to spray gun and tighten firmly.
2. Take pump handle RMKIT 7 and insert into the tube on the

pump lever RMKIT 5 ("T" shape lever on sprayer), you will
notice holes drilled through both sides of both the pump
handle and the pump lever. Align these holes, take the "R"
pin provided and place through the holes. This affixes the
handle in place and is ready for use.
For storage reverse process and then place "R" pin through
the pump lever RMKIT to keep from losing "R" pin.

3. Instructions for installing shoulder strap plastic buckle:

First put the sprayer on a hard flat surface, take the white
plastic buckle and while holding the sprayer up slightly,
place buckle under the tubular metal frame. Slowly push
down forcing the frame into the buckle. Repeat the same
procedure for other side.
