can split the pump body or damage the hose.
8.
When the suction strainer is likely to clog with muck and roots,
prepare a bed of stones on which to rest the strainer; or tie the
strainer so that it stays off the bottom; or tie it in a basket or pail (see
illustration).
9.
When pumping liquids (such as Liquid Fertilizer) containing solids,
the time required to prime will increase and the pumping volume
(gallons per minute) will decrease as the proportion of solid matter in
the liquid to be pumped is increased. The viscosity or thickness of
the liquid also will affect the priming time and the pumping volume.
Any consistency of liquid which increases friction and drag in the
pump and lines will retard the output.
10. The rubber molded check valve in the “chimney” of the pump volute
will seal off the pump to retain liquid in the suction line so that the
pump will start pumping immediately after short periods of shut-
down.
11. When the pump is used only now and then, it is a good idea to check
that the unit is ready for operation by (a) checking the level of oil in
the engine crankcase and (b) filling the pump with liquid.

INSTRUCTIONS
1.
When pumping dirty water or liquids
containing solids, always use a pump strainer on the end of
the suction line.
2.
Make sure that all hose and pipe connections are air tight. An air
leak in the suction line may prevent priming and will reduce the
capacity of the pump. Also be sure that the filler plug on top of
the pump and the drain plug at bottom rear are air tight.
3.
Always place the pump as close to the liquid to be pumped as
possible but not in an enclosed area. Keep the pump and
engine on a level foundation. When the suction
hose is hanging down a steep bank or into a hole, the weight
of the hose and the liquid in it can pull the pump into the liquid. To
prevent “walking” and possible loss of the pump, tie it
down.
4.
Always be sure the pump contains liquid before you start the
engine. In freezing weather, always drain liquid from the pump after
use. After refilling pump in freezing weather, crank engine very
slowly so you can feel whether pump is free to run before you crank
to start the engine. If pump is frozen, thaw it out slowly. (Do not use
fire to thaw pump).
5.
If pumping liquid is contaminated with mud or detergents (many
rivers and lakes contain detergents) which will churn into suds in the
pump, it may be necessary to prime the pump with clean water (tap
water). Once primed, the pump will handle the contaminated liquid.
6.
Maximum volume is achieved by:
(a)
Keeping lines as straight as possible, and avoiding kinks and sharp
bends in the hoses.
(b)
Making the vertical suction lift distance as short as possible (see
illustration).
(c)
Using large diameter suction and discharge lines (The larger the
diameter the lower the friction).
(d)
Using as few connectors, elbows and adapters as you can get away
with.
(e)
Maintaining the pump and associated equipment in good operable
condition.
7.
If flexible hose must be laid across a roadway, protect it with
planking. Instantaneous shut-off pressures, applied when a vehicle
runs across an unprotected hose, will cause pounding. Pounding
