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 (15) downward, remove
plug (15) and drain all oil from seal chamber. Apply pipe
sealant to pressure gauge assembly and tighten
into hole in seal housing (16). Pressurize seal chamber to
10 P.S.I. and check for leaks.
Oil Replacement Motor Housing
Remove pipe plug (15) from motor housing (19).
Drain all oil (if not already done so) from motor housing
(19) 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 (2.3L) 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 (15) then assemble to motor housing
(19). Check that o-ring (12) is in place and does not need
to be replaced. Reassemble cord cap to motor housing.
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 (15) upward, and refill with new oil
(.75L), see "Cooling Oil" chart. Apply pipe sealant to
threads of pipe plug (15) and assemble to intermediate
coupling (21B)
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.

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 cutter and shredding ring and
remove screw. With a hammer and punch, tap the cutter
(5) counter-clockwise to remove.
CAUTION
removed before removing volute.
Volute - Remove hex bolt(1) from volute (7).
Shredding Ring - To replace or reverse the shredding
ring (6) remove plate (2).
Impeller - Remove impeller (9) 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 (10) 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 (10) if necessary..
Seal Plate - Remove cap screws (14) from seal plate (11).
Remove seal plate (11) and o-ring (12) from seal housing
(16). With flat screwdriver, press out seal (10) stationary
member. Inspect o-ring (12) for cuts or abrasions.
Checking Capacitors - Remove cap screws (32) from cord
cap (33). Check motor capacitors (24) & (30) with an Ohm
meter 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.
