FIGURE 1 - Typical Installation
2. For a permanent installation, mount the unit on a foundation that will support the weight of the pump and engine
and also provide stability while the pump is running. For most permanent installations, it is advisable to bolt the unit
directly to the foundation.
NOTE: Setting and/or shifting during operation can cause piping to place excessive strain on the pump and may
damage the pump case. Set the pump on a hard level surface.
3. Connect suction hose (not included) to the pump suction. The hose must be rated to hold the suction pressure and
prevent collapse while the pump is running.
4. Make the suction hose a continuous rise from the water source to the pump. High spots can trap air and also
make priming difficult. Make sure all connections are tight and free of air leaks.
NOTE: Suction hose must be at least as large as the pump suction port in order for the pump to operate properly.
5. Install the strainer (provided with the pump) on the other end of the suction hose and secure it with a hose clamp.
NEVER OPERATE THE PUMP WITHOUT THE STRAINER INSTALLED.

7. Tighten the clamp securely to prevent the discharge hose from disconnecting under high pressure.
INSTALLATION REQUIREMENTS
• Use reinforced hose to make the suction connection.
• Hose must be strong enough to not collapse during operation.
• Suction screen area must be at least four times suction pipe area.
• All suction hose must slope up toward suction port.
• Supportthehoseandttingstoreducestrainonthepumpcase.
• Depth of suction port must be at least (4) times the diameter of the suction hose to avoid forming vortexes....
EXAMPLE: 2” Pipe x 4 = 8” minimum depth.
NOTE: Do not start or run the pump dry or damage to the mechanical seal will result.
NOTE: Add engine oil before startup.

the pump will reprime automatically at each subsequent start-up. If the pump is used in portable applications and
the water has been drained from the pump case, re-prime before start-up.
2. Toprime,removethewaterlterplug6(seepage6)fromthetopdischargeportandllthepumpwithwater.
Replace the plug and start the pump. The pump will require a few minutes to evacuate air from the suction line.
After several minutes of operation, the pump will be fully primed and pumping water. Priming time will vary
depending on the length and diameter of the suction line.

REPAIR AND MAINTENANCE
MAINTENANCE OF SPARK PLUG (MODEL F6RTC)
To ensure the normal operation of the engine, ensure the spark plug is always clean and properly adjusted as the
steps below show:
1. Remove the spark plug by twisting counterclockwise.
2. Gently remove any carbon deposits from the plug.
3. Ensure the clearance is between 0.6~0.8mm.
MAINTENANCE BEFORE A LONG-TERM SHUTDOWN
If the engine will not be used for a long period of time, perform the following maintenance steps on the engine before
shutdown:
1. Unscrew the fuel switch, unscrew the oil drain bolt at the bottom of the carburetor, and tighten the bolt after
complete release of fuel in the tank and carburetor.
2. Unscrew the oil drain bolt at the bottom or the crankcase to completely release the lubricating oil in the crank
case, and then tighten the oil drain bolt.
3. Perform the following maintenance steps on the engine cylinder:
o Remove spark plug
o Pour a teaspoon (5cc) of clean engine oil into the cylinder.
o Pull the start handle several times to distribute the oil in the cylinder.
o Reinstall the spark plug.
o Pull the handle slowly until resistance is felt and the notch on the starter pulley aligns with the hole at the
top of the recoil starter cover. This will close the valves so moisture cannot enter the engine cylinder.
Return the start handle gently.
4.Wipeotheoilstainanddustontheexternalsurfacewith
a cleaning cloth and remove the dirt between the
coolingns,soastokeepthegasolineengineclean.
After cleaning, store the engine in a clean, dry and
ventilated location.
THE SPARK PLUG MUST BE SECURELY TIGHTENED IN THE ENGINE. OTHERWISE, THE COMBUSTION
CHAMBER WILL NOT BE AIRTIGHT DURING OPERATION. THE LEAKAGE OF COMPRESSED AIR WILL REDUCE
ENGINE POWER AND SERIOUS LEAKAGE WILL LEAD TO ENGINE FAILURE.
