TROUBLE SHOOTING
NOTE: Most common cause of failure to run is due to hardened mud and sand at impeller. Remove strainer to check.
MOTOR WILL NOT RUN:
1. Poor connection at battery.
2. Impeller locked with foreign material.
3. Insufficient impeller clearance.
4. Damaged power cable or loose connection internally in motor assembly.
5. Bad switch or circuit breaker. Connect power leads direct to motor leads to check.
6. Worn motor brushes or out of position to make contact with armature.
PERFORMANCE LOW:
1. Strainer screen partially plugged.
2. Impeller rubbing. Check freeness of rotation with screwdriver inserted through hole in base plated into slotted end of
shaft.
3. Battery not fully charged.
4. Discharge restriction such as kinked hose or excessive discharge head.
Motor runs backwards:
1. Check wiring for correct polarity.
SERVICE AND REPAIR INSTRUCTION
DISASSEMBLY: Impeller and shaft seal can be inspected and serviced from lower end of pump by removal of 4
capscrews securing base plate, strainer screen, and suction cover. Screwdriver slot is provided in end of motor shaft to turn
shaft while holding impeller for removal. This permits removal of impeller without disassembly of upper motor housing to hold
motor shaft. Alternately, there is a shaft extension with two flats on the rear of the motor for use when the impeller is difficult
to remove. The upper motor cover must be removed to expose this shaft extension.
To service motor remove 4 hex nuts and bump top cover free from housing tube. Raise sufficiently to disconnect power
cable connections. Slide housing tube up from pump casing and motor will be exposed for service or removal.
When servicing and replacing the impeller or suction cover, follow these instructions: The impeller has been revised to
typically require 1 shim (previously 7). The suction cover has been revised to require 1 gasket.
IMPORTANT: Make certain that wire leads are installed per diagram below. Install top cover as indicated by arrow and
instruction on top of cover. Make sure wires do not contact motor shaft when installing motor cover.
