Stainless Steel Pump
Instruction Manual
Read these instructions and the instructions covering the operation of the engine before
starting the engine. Do not operate the engine until you have put oil in the engine
crankcase. It is wise to check the oil level each time the gasoline tank is filled. If the pump
is used only occasionally, check oil and gasoline before
starting engine.
Do not run the pump dry. Always fill the pump body with
water (or liquid to be pumped) before starting pump. It
is not necessary to drain the pump body after use,
unless there is a danger of freezing.
Use a regular grade of gasoline (unleaded and
uncolored if available). Remove the engine
cylinder head after 100 hours of operation and
remove the carbon and lead deposits from the
combustion chamber and top of the piston.
Make certain 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.
Always place the pump as close to the liquid to be pumped
as
as possible. Keep the suction line short and with few bends.
Keep the pump and engine on a level foundation. A poor foundation
and a heavy suction hose (made heavier when “primed’ full of
liquid) could result in a pump “down the hole”.
There are important instructions regarding
preparing the engine for long periods of idleness.
(Read the engine instruction manual). Under these
conditions, drain the pump completely, turn the engine
over a few times and leave all plugs (filter and drain) out of
the pump. Always try to store the unit in a heated and dry
building.
When pumping dirty water or other liquids containing
solids, always use a pump strainer on the end of the
suction line. There are no points on the pump which need
lubric tion.
lubrication. The shaft seal is self-lubricating, and designed to handle clean or dirty liquids.
