Apply pipe sealant to pressure gauge assembly and tight-
en into hole. Pressurize motor housing to 10 P.S.I. Use
soap solution around the sealed areas above the oil level
and inspect joints for "air bubbles". For sealed areas
below oil level, leaks will seep oil. If, after five minutes,
the pressure is still holding constant, and no "bubbles" /
oil seepage is observed, slowly bleed the pressure and
remove the gauge assembly. Replace oil. Leak must be
located and repaired if pressure does not hold.
Seal Chamber Pressure Test
Set pump on its side with fill plug (13) downward, remove
plug (13) and drain all oil from seal chamber. Apply pipe
sealant to pressure gauge assembly and tighten
into hole in seal plate (15). Pressurize seal chamber to 10
P.S.I. and check for leaks.
Oil Replacement Motor Housing
Remove pipe plug (30) from motor housing (28).
Drain all oil (if not already done so) from motor housing
(28) and dispose of properly per Local Code. Set pump
upright and refill with new cooling oil, see "Cooling
Oil" chart. Fill to just above motor (2.1L) as an air space
must remain in the top of the motor housing to compen-
sate for oil expansion. Apply pipe thread compound to
threads of pipe plug (30) then assemble to motor housing
(28).
Oil Replacement Seal Chamber
Drain all oil (if not already done so) from seal chamber
and dispose of properly per Local Code. Place pump on
its side with plug (13) upward, and refill with new oil (.4L),
see "Cooling Oil" chart. Apply pipe sealant to threads of
pipe plug (13) and assemble.
DO NOT overfill oil. Overfilling of housing
with oil can create excessive and dangerous
hydraulic pressure which can destroy the
pump and create a hazard. Overfilling
oil voids warranty.

WARNING
disconnect and lock out electrical power to
pump.
Cutter Disassembly
Lay pump on its side and remove the cutter retaining
screw (3) and washer (4). A small amount of heat may be
needed to loosen screw. DO NOT overheat. Wedge a flat
screwdriver between rotating (6) cutter and stationary
cutter (8) and remove screw. Remove the rotating cutter
(6) and square key (5) by sliding straight off shaft (22).
Be careful not to misplace shim washers (7), as these are
needed to properly space rotating cutter (6) from station-
ary cutter (8).
CAUTION
removed before removing volute.
Volute - Remove hex bolt (29) from volute (9).
Stationary Cutter - To replace or remove the stationary
cutter (8) remove plate (2) by removing screws (1).
Impeller - Remove impeller (10) by turning counter-clock-
wise while holding the motor shaft stationary with a
screwdriver. Do Not store pump without impeller in
place.
Outer Seal- Handle seal parts with care. Remove spring
and rotating portion of seal (12) from shaft. Examine all
seal parts. Inspect contact faces for signs of uneven wear
tracks on stationary face, chips and scratches on either
seal face. DO NOT interchange seal components, replace
the entire shaft seal (12) if necessary.
Seal Plate - Remove screws (14) from seal plate (15).
Remove seal plate (15) and o-ring (16) from bearing plate
(17). With flat screwdriver, press out seal (12) stationary
member. Inspect o-ring (16) for cuts or abrasions.
Checking Capacitors When Equipped - Remove cap
screws (1) from cord cap (45). Check motor capacitors
(36) & (38) by placing a screwdriver with an insulted
handle across both terminals and to ground to discharge
the capacitor then remove. Connect Ohm meter, set on
high scale to terminals. If needle moves to zero then
drifts back, the capacitor is good. If needle does not
move or moves to zero and does not drift back, replace
the capacitor.
