MQ41TDH TRASH PUMP — PARTS & OPERATION MANUAL — REV. #3 (04/02/07) — PAGE 15
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 1) and fill pump case
with water. If the pump case is not filled with water before
starting, it will not begin pumping.
MQ41TDH — PRE-SETUP (PUMP)
NOTE
Pump case must be filled with water
before using pump. Otherwise pump will
not be able to begin pumping.
WARNING
DO NOT open fill cap if pump
is hot! Water inside may be
under pressure.
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 1) 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 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 1) 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.
6. Make sure the suction strainer (Figure 1) 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.
NOTE
Suction and discharge hoses are available
from Multiquip. Contact your nearest dealer
for more information.
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.
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.
