PAGE 16 — QP-301TH TRASH PUMP — PARTS MANUAL — REV. #4 (10/05/05)
Before Starting
1. Read safety instructions at the
beginning of manual.
2. Place pump as near to water as
possible, on a firm flat, level surface.
3. To prime pump, remove fill cap (Figure 2) and fill pump casing
with water. If the pump casing is not filled with water before
starting, it will not begin pumping.
QP-301TH — PRE-SETUP (PUMP)
4. Check for
leaks
between pump and engine. If water is leaking
between the pump and engine housing, the seal inside the
pump may be worn or damaged. Continued operation of the
pump is not recommended. Further usage of the pump under
these conditions may cause severe water damage to engine.
Hoses and Clamps
1. Check that all hoses are
securely
attached to the pump.
Make certain suction hose (Figure 2) does not have any air
leakage. Tighten hose clamps and couplings as required.
2. It is recommended that 2 clamps be used when securing the
suction hose to the inlet side (suction) of the pump.
3. Remember suction hoses must be
rigid
enough not to
collapse when the pump is in operation.
4. Check that
the
discharge
hose (Figure 2) is not restricted.
Place hose so that it lays as straight as it is possible on the
ground. Remove any twists or sharp bends from hose which
may block the flow of water.
CAUTION :
Pump casing
must
be filled with water
before using pump. Otherwise pump will not
be able to begin pumping.
DO NOT open
fill cap
if pump is hot! Water
inside may be under pressure.
WARNING :
NOTE
Suction and discharge hoses are
available from Multiquip. Contact
your nearest dealer for more
information.
5. The discharge hose is usually a
collapsible
(thin-walled)
hose, however if a thin-walled discharge hose is not avail-
able, a rigid suction hose can be substituted in its place.
6. Make sure the
suction strainer
(Figure 2) is clean and
securely attached to the water end of the suction hose. The
strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.
CAUTION :
The strainer should be positioned so it will
remain completely
under water
. Running the
pump with the strainer above water for long
periods can damage the pump.
CAUTION :
DO NOT pump flammable fluids, corrosive
chemicals or fluids containing toxic substances.
These fluids can create potentially dangerous
health and environmental hazards. Contact
local authorities for assistance.
CAUTION :
This pump uses a water-cooled
mechanical
seal
to prevent water from seeping into the
engine. The passage of water through the
pump casing lubricates the seal and prevents
it from overheating.
NEVER!
operate the pump
without water in the casing as this will cause
damage to the mechanical seal.
