for a complete unit:
■
GP344 engine-driven pump
Spark plug wrench ■
Install the Suction and Discharge Hoses
Spanner ■
3mm Hex Wrench ■
4mm Hex Wrench ■
Parts bag including: ■
1.0" hose clamps (3 each) ■
hose ttings and gaskets ■
(2 each)
■
strainer
garden hose adapter (use gar- ■
den hose only to discharge
water!)
CAUTION!
This pump is intended for pump-
■
ing fresh water only.
■
Ingested debris can damage the
pump impeller and seals.
■
Never operate the pump if the
strainer is missing or damaged.
Assemble a barbed hose tting, 1.
ring nut, and gasket as shown, and
thread the completed hose tting
assembly onto the pump suction
port.
Push a 1.0" suction hose (not pro-2.
vided) over the suction hose tting on
the pump body, and secure with a 1.0"
hose clamp as shown. Working at the
opposite end of the suction hose, use
a second 1.0" hose clamp to install and
secure the suction strainer.

IMPORTANT!
Place the pump as close to the water
source as possible. Increases in suction lift will lower pump performance.
Do not exceed maximum suction head
of 26 feet.

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, additional priming should be required only
if the pump has been drained or otherwise 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.
IMPORTANT!
A damaged or missing ller plug
seal may allow air to leak into the
pump housing. Air leakage can lower
performance!
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.
CAUTION!
Never allow the pump to run dry!
Operation without water can permanently damage the pump seals.

Mixing Fuel
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 4TM 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 ArmorTM engine oil in all Shindaiwa Hybrid 4TM engines to
protect the engine from harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa
Red ArmorTM 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.
IMPORTANT!
Shindaiwa Red Armor
in all Shindaiwa engines sold in the past, regardless of ratio specied in those
manuals.
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, improperly 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.

Handling Fuel
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow ames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before starting the engine.
Mixing Instructions
1. Fill an approved fuel container with half of the required amount of gasoline.
2. Add the proper amount of engine oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Add remaining gasoline, close fuel container, and
remix.
IMPORTANT!
Spilled fuel is a leading cause of hydrocarbon emissions.
Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage.
