Maintenance
Make certain that
unit is
disconnected from power source
before attempting to service or
remove any component.
POWER CORD REPLACEMENT
Periodically inspect power cord and
replace whenever abrasion, cracking,
softening, or other signs of
deterioration are found.
Refer to Figures 2 and 3.
1. Place unit on workbench in upright
position.
2. Remove two fasteners (Ref. No.
39) which hold outer cord retainer
(Ref. No. 38).
3. Remove fasteners(s) (Ref. No. 5)
at handle (Reef. NO. 6) to free
wire loom (Ref. No. 2).
4. Remove three fasteners (Ref. No.
36) to detach handle and outer
shell (Ref. No. 37). Shell can now
be slid off towards top of pump.
5. Clean dirt and rust from around
wire cover (Ref. No. 7).
6. Remove two fasteners (Ref. No.
4) which hold inner cord retainer
(Ref. No. 3).
7. Remove four fasteners (Ref. No.
10) which hold wire cover in place.
8. Carefully pry cover from unit with
screwdriver.
IMPORTANT:
Be careful to keep rust
and other debris from falling into motor
housing during cover removal.
9. Take note of proper wire
configuration and connect new
power cord (Ref. No. 1) in
identical fashion.
If unsure about
above information
or wiring diagrams, consult an
electrician familiar with motor
wiring.
10. Clean sealing flanges if necessary
and reassemble pump in reverse
order.
IMPELLER INSPECTION /
REPLACEMENT
If pump develops poor performance
characteristics, impeller may be worn
or clogged.
IMPELLER INSPECTION
Refer to Figure 3.
1. Place unit on workbench in
horizontal position and clean rust
and buildup from around pump-to-
motor flange.
2. Remove four short fasteners (Ref.
No. 15) which attach base (Ref.
No. 30) to unit.
3. Pry base off with screwdriver. Rap
down on pump body with soft
mallet if necessary to separate
parts.
4. Inspect impeller (Ref. No. 26). If
clog is found, remove debris and
reassemble in reverse order. If
damage to impeller is found, such
as pitting, deep grooves, or
breakage, proceed to next section.
IMPELLER REPLACEMENT
5. Remove impeller fastener (Ref.
No. 28) by unscrewing in
