3. Belt Inspection - Inspect the belts for
cracks, damage, glazing or any other
defect. Replace as necessary. Replace the
belts as a set and adjust the new belts as
outlined in “Adjusting Belt Tension” on
page 75.
4. Regular Stuffing Box Lubrication Check
- Remove stuffing boxes, clean power -
frame bore, lubricate with anti-seize
or petroleum jelly, and replace stuffing
boxes.
Winterizing The Unit
Severe damage can result if the waterblast
unit is not protected from freezing condi-
tions. The stuffing boxes hold water that can
freeze causing damage to the stuffing boxes,
uni-valves, plungers and manifold. To prevent
freezing drain the water from all hoses, charge
pump and tanks, and add anti-freeze to the
stuffing boxes.
If the unit is to be idle for any period of time
that would allow freezing in the pump or pip-
ing, utilize the following procedure:
1. Drain the water from the tank.
2. Disconnect the water supply suction line
and high pressure discharge hose from the
manifold.
3. Drain the manifold of water and close the
drain.
4. Assemble pipe fittings into a funnel as -
sembly as shown in (Figure 44).
5. Install the assembly on the suction side
of the manifold.
6. Pour a glycol based anti-freeze solution
into the funnel as shown in (Figure 45).
Approximately 0.5 gal. (2 L) of anti-freeze
is required.
7. Place the override switch in the ON posi-
tion to bypass the low water shutdown.
8. Before starting the engine, check the area
in the path of the discharge fitting on the
manifold. Ensure the area is clear. Anti-
freeze will be discharged from the dis-
charge fitting during this procedure.
