tery connection from the primer solenoid. (See Figure 3-1: “Solenoid Con-
nector Arrangement” on page 18.)

Inspect:
❑
Rotor vanes for excessive wear and scaring — replace if necessary.
❑
Inside surface the pump body for scaring or pitting.
❑
Bearings in pump head and body for excessive wear, scoring, etc.
Repair and/or replace parts as needed.
Note: Abrasives passing through the pump can damage sealing surfaces. Corrosion
and/or the breakdown of biodegradable lubricants can cause rotor vanes to stick or
break. Sand entering the pump can cause the vanes to stick or break and can dam-
ages the inside wall of the pump body. Replace defective parts.
Wherever there is a requirement for new parts, it is recommended to use only Hale
authorized replacement parts for optimum safety of the equipment and its operators
and to limit “downtime.”
