M3-G
Filter / Shear System
The filter / shear system on the M3-G is an integral part of the mixing system and to operate efficiently
requires daily cleaning of the stainless steel internal filter /shear. The filter / shear system is a two-piece unit
consisting of an outside housing and an internal filter / shear. The filter / shear will trap any debris, such as
parts of bags, stones, leaves grass etc. The proper procedure for cleaning the filter shear is to close any
valve(s) in the suction line, from the reservoir tank to the pump, remove the 5 inch Snap Lock coupler at the
left end of the filter housing, remove the 3 inch Snap Lock coupler at the discharge port of the centrifugal
pump. You will now be able to remove the internal filter / shear from the housing, after the internal filter /
shear has been removed, you will see on the end of the filter / shear a cover plate. Remove the cover plate and
wash out the filter / shear with clear water. Reinstall the cover plate on the filter, reinstall the filter in the
housing (Note the small block on the bottom of the screen, this is placed on the bottom of the filter housing to
line up the 5 inch Snap Lock coupler and gasket) do-not
clamp the 5 inch coupler until the 3 inch coupler and
gasket are properly lined up. After all pieces are correctly lined up, clamp the 5 inch coupler 1
st
and 3 inch
coupler 2
nd
and reinstall the safety pins.
NEVER attempt repairs or disassembly without shutting off the unit. Serious personal injury will
result.
TRAPPED fluid may be present and will spill out when piping, pump front cover or filter/shear is
removed.
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.
BEFORE starting or restarting the engine and centrifugal pump, make sure the butterfly valve on the
pump intake line is open.
CARE must be taken that the coupler gaskets are properly installed or a leak may develop.
Pressurized Wash Wand
The wash wand is a maintenance tool used to clear obstruction and build-up in the jetting TEE under the
hopper. The wand uses the fluid circulating thru the system and the pressure of the pump to produce a
concentrated stream of fluid to aid in dislodging build-up around the jetting nozzle and hopper valve. DO
NOT use the wash wand as a pry bar or scraper as damage may occur. Let the force of the fluid stream do
the work. To use the wash wand properly, first place the wand inside of the hopper, slowly open the valve
and direct the fluid stream down into the throat of the hopper. Caution should be taken to keep the wand out
of the stream exiting the jetting nozzle, as splash back will occur. After using the wash wand, it should be
stored back into its holder.
The wash wand may also be used to obtain a fluid sample for testing purposes. This will give the same
sample as the “Drill Fluid Out”. Caution should be taken, as the flow will have to be reduced. To get a good
sample, place the wand inside the hopper and open the valve slowly. Let fluid flow out of the wash wand to
remove all other fluid in the hose (approx. 20 sec.). Now take the sample, close the valve and return the wash
wand back to its holder.
DO NOT position any part of your body over the hopper when cleaning with the wash wand.
