Pump Service - STA-RITE HC-01 Owner's Manual

LUBRICATION
Motor is lubricated at factory for life of bearings. Pump seal
is water cooled and self lubricating.

PUMP SERVICE

Motor has auto-reset thermal overload. If motor overheats,
overload will cut off power to prevent damage and will reset
after motor cools. If overload trips repeatedly, check pump
for cause (low voltage, clogged impeller, etc.).
Hazardous voltage. Can shock, burn, or
cause death. Disconnect motor from electrical power
before servicing pump.
Always replace BOTH brushes - to avoid fire hazard,
never replace just one.
Motor Brush Replacement:
Replace brushes when they wear down to 1/2" length.
1. Unplug pump from power outlet.
2. Unscrew brush caps (Key No. 6, Figure 2) and remove
brushes (Key No. 7).
3. Install new brushes and brush caps.
NOTICE: When reinstalling the same brushes that were
removed, replace on same side of motor that they were
on originally. Match curve on ends of brushes to curve
on commutator.
