OPERATING THE M3-G
Before Starting
•
READ
engine operators manual for proper starting and running procedures.
• CHECK to assure the engine oil level is correct. Refer to the operator manual supplied by the engine
manufacturer.
• CHECK to assure the air filter is clean (replace if necessary).
• CHECK to assure the gasoline fuel tank is full and the shut off valve is open.
• CHECK to assure any valves installed on the pump intake line are open.
• CHECK to assure there is sufficient fluid in the reservoir tank, to not run the centrifugal pump dry.
• REMOVE the priming plug, check and/or fill pump casing with water, replace and tighten plug.
• CHECK to assure the ball valve connected to the filter housing marked “Drill Fluid” is closed.
• CHECK to assure the ball valve connected to the filter housing marked “ Tank Gun” is open.
• CHECK that hopper valve is closed
• CHECK that the wash wand valve is closed
Starting Engine
• Set the speed control lever 1/3 of the way towards the high-speed position.
• If the engine is cold or the ambient temperature is low, close the choke fully.
• If the engine is warm or the ambient temperature is high, close the choke lever half-way, or keep it fully
open.
• Pull the starter recoil handle slowly until resistance is felt. This is the compression point. Return the
starter recoil handle to its original position and pull swiftly. Do not pull out the rope all the way. After
starting the engine, allow the starter recoil handle to return to its original position while still holding the
handle.
• After starting the engine, gradually open the choke until fully open. Do not fully open the choke lever
immediately when the engine is cold or the ambient temperature is low, or the engine may stop.
• After the engine starts, set the speed control lever at the low speed position and warm it up without load
for a few minutes.
• Remember that the system is pumping fluid under pressure, even when the engine is idling.
• Gradually move the speed control lever toward the high-speed position and set at the required speed.
Note
: Whenever high-speed operation is not required, slow the engine to down by moving the speed control
lever to save fuel and extend engine life.
The Robin / Monarch pump used on this unit is self-priming. Priming is not required as long as the pump is
kept full of liquid.
BEFORE STARTING OR RUNNING THE ENGINE BE SURE THE PUMP IS PRIMED! This is
checked by slowly unscrewing the plug on the top of the centrifugal pump. Water will leak out as the
plug is loosened or a visual inspection can be made if the plug is removed. The centrifugal pump
WILL be damaged if allowed to cavitate or run dry.
