Hydra Sprayer Manual 8
Maintenance & Cleaning
1. Periodically check the pump oil level (G) If it is
below the indication add oil though the filler (H).
Use only Shell “Tellus #32” hydraulic oil or
equivalent.
2. Periodically lubricate the grease fittings on the
wheels (I &J) with a good grade of bearing grease to
extend the wheel bearing life.
3. Replace the spray gun tip every season. As the hole
in the tip gets larger the spray pressure drops and
degrades the quality of the spray. (K)
4. Thoroughly clean the in-line filter, tank and
machine on a weekly basis. (L)
5. To drain tank, rotate the drain valve (M) 180° until
the arrow on the valve handle indicates the direction
of flow is out the drain hose. *After draining, turn
the valve back to the Spray position. This
ensures that upon refilling the tank- the chemical
will not drain out of the unit.
