Priming
Before the pump can develop suction
or “lift” at the water source, the pump
impeller must rst be primed by lling
the pump housing with water. Once the
water pump has been primed, addi-
tional priming should be required only
if the pump has been drained or other-
wise emptied.
Remove the ller plug at the top of 1.
the pump housing. Use care not to
lose the sealing ring beneath the
ller plug.
CAUTION!
Never allow the pump to run dry!
Operation without water can perma-
nently damage the pump seals.
Fill the pump housing through the 2.
priming port with clean water until
water overows from the ller plug
hole on the pump body.
Replace and securely tighten the 3.
ller plug.
IMPORTANT!
A damaged or missing ller plug
seal may allow air to leak into the
pump housing. Air leakage can lower
performance!
WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa
requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause
performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including,
but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel
lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain
up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood
alcohol) is NOT approved.
Hybrid 4
TM
Mixture Oil - Engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards must be
used. Shindaiwa highly recommends using Shindaiwa Red Armor
TM
engine oil in all Shindaiwa Hybrid 4
TM
engines to
protect the engine from harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa
Red Armor
TM
engine oil exceeds ISO-L-EGD and J.A.S.O. M345/FD performance requirements. Engine problems
due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certied
oil will void the engine warranty.
Mixing Fuel
Examples of 50:1 mixing quantities
IMPORTANT!
Shindaiwa Red Armor
TM
engine oil may be mixed at 50:1 ratio for application
in all Shindaiwa engines sold in the past, regardless of ratio specied in those
manuals.
IMPORTANT!
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30)
days, ninety (90) days when a fuel stabilizer is added. Use of unmixed, improp-
erly mixed, or stale fuel, may cause hard starting, poor performance, or severe
engine damage and void the product warranty. Read and follow instructions in
the Long Term Storage section of this manual.
