Owner’s Manual for Water Pump 7
Section 3 Operation
Operation and Use Questions
If you have any problems operating your water
pump, please call Generac customer service
at 1-888-GENERAC (888-436-3722).
Placing Water Pump for Use
It is a violation of California Public Resource
Code, Section 4442, to use or operate the
engine on any forest-covered, brush-covered,
or grass-covered land unless the exhaust
system is equipped with a spark arrestor, as
defined in Section 4442, maintained in
effective working order. Other states or federal
jurisdictions may have similar laws. Place the
pump on a level surface free from any
obstructions or potential hazards. The pump
should be placed close to the water level to
ensure maximum performance.
Only operate water pump outdoors in a well
ventilated area. Never operate water pump
indoors, or in a confined space. Be aware
of building openings and ventilation
systems where exhaust may enter during
use.
Keep at least five (5) ft (152 cm) of
clearance on all sides of water pump
including overhead.
Verify water pump is placed on level
ground to avoid tipping during operation.
Submerge strainer.
NOTE: Suspend the strainer if there is any
mud or sand present at the bottom of the
water.
Place discharge hose in appropriate
location to drain water. Verify that the hose
opening is unobstructed.
Figure 3-1. Five Feet of Minimum
Clearance
Pump Output
See Figure 3-2. Pump output will be affected
by the type, length, and size of the suction and
discharge hoses. Suction head is the distance
(A) from the water intake to the suction port.
The pumping height, total head, is the
distance (B) from the water intake to the point
of discharge. As total head increases, the
pump output decreases. The discharge
capacity is greater than the suction capacity.
Therefore, it is important to keep the suction
head less than the total head. The time
required to draw water from the source to the
pump (self-priming time) can be decreased by
minimizing the suction head.
Figure 3-2. Pump Output
High Altitude Operation
This equipment produces maximum suction lift
at elevations below 1000 ft (305 m). For every
increase of 1000 ft (305 m) above sea level:
the engine will lose about 3% of its power
total head will be reduced by about 10 in
(25 cm).
Lower atmospheric pressure results in slower
engine speeds and reduced water flow
through the pump.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.

Storage
Refer to the following list to prepare
equipment for storage.
DO NOT place a storage cover on a hot
water pump. Allow equipment to cool to
room temperature before storage.
DO NOT store fuel from one season to
another unless properly treated.
Replace fuel container if rust is present.
Rust in fuel will cause fuel system problems.
Cover equipment with a suitable protective,
moisture resistant cover.
Store equipment in a clean and dry area.
Always store water pump and fuel away
from heat and ignition sources.
Prepare Fuel System for Storage
Fuel stored over 30 days can go bad and
damage fuel system components. Keep fuel
fresh, use fuel stabilizer.
If fuel stabilizer is added to fuel system,
prepare and run engine according to "Starting
the Engine" Run engine for 10-15 minutes to
circulate stabilizer throughout fuel system.
Adequately prepared fuel can be stored up to
24 months.
NOTE: If fuel has not been treated with fuel
stabilizer, it must be drained into an approved
container. Run engine until it stops from lack
of fuel. Use of fuel stabilizer in fuel storage
container is recommended to keep fuel fresh.
1. Change engine oil.
2. Remove spark plug.
3. Pour a tablespoon (5-10cc) of clean
engine oil or spray a suitable fogging
agent into cylinder.
4. Pull starter recoil several times to
distribute oil in cylinder.
5. Install spark plug.
6. Pull recoil slowly until resistance is felt. This
will close valves so moisture cannot enter
engine cylinder. Gently release recoil.
Change Oil
Change engine oil before storage. See
Change Engine Oil
Prepare Water Pump for Storage
Protect equipment from freezing
temperatures. Failure to do so will
permanently damage pump and render
equipment inoperable. Freeze damage is not
covered under warranty.
Protect equipment from freezing temperatures
as follows:
1. Shut engine off by turning engine start
switch to OFF.
