• Close the fuel cock before filling the fuel tank. (EW220R,EW320TR)
• Do not fill above the top of the fuel filter screen (marked LEVEL), or the fuel may overflow when it heats up later and expands. (EW220R, EW320TR)
• When filling the fuel tank, always use the fuel filter screen.
  Wipe off any spilled fuel before starting the engine.

CHECK PRIMING WATER

It is recommended that the water chamber of pump casing should be primed with full of water before operating.

WARNING

Never attempt to operate the pump without priming water or the pump will overheat. Extended dry operation will destroy the mechanical seal. If the unit has been operated dry, stop the engine immediately and allow the pump to cool before adding priming water.

1. STARTING

(a) Open the fuel cock. (EW220R,EW320TR)
(b) Set the speed control lever to the idling position (L). (EW120R)

Set the speed control lever 1/3 of the way towards the high speed position. (EW220R,EW320TR)

(c) Turn the STOP SWITCH to the position "I" (ON).

If the engine is cold, or the ambient temperature is low, close the choke lever fully.
If the engine is warm or the ambient temperature is high, close the choke half-way, or keep it fully open.

(e) Pull the starter handle slowly until resistance is felt. This is the "compression" point. Return the handle to its original position and pull swiftly.

Do not pull out the rope all the way. After starting the engine, allow the starter handle to return to its original position while still holding the handle.

(f) After starting the engine, gradually open choke by turning the choke lever and finally keep it fully opened. Do not fully open the choke lever immediately when the engine is cold or the ambient temperature is low, because the engine may stop.

2. RUNNING
