****** CAUTION ******
BEFORE STARTING THIS MOTOR, DISENGAGE THE
MOTOR/PUMP COUPLER (LOVE JOY) AND CHECK THE
MOTOR FOR PROPER ROTATION. IF THIS STEP IS NOT
FOLLOWER, THE IMPELLER MAY BECOME SEPARATED
FROM THE SHAFT AND CAUSE SUFFICIENT DAMAGE TO
THE PUMP AND IMPELLER AND OR PERSONAL HARM.
To disengage the coupler, remove the guard, loosen the setscrew on each
coupler and slide the couplers back away from each other and TIGHTEN the
setscrews back up. Remove the black insert. Reinstall the guard, and then
switch the motor on/off and as the shaft slows down, you will be able to see the
rotation direction. If the need be, change the wiring to provide the proper
rotation.

Operators Manual
Congratulations on your acquisition of the world renowned M4 Mixing System. You have acquired the
fastest and most efficient mixing system manufactured for mixing Bentonite drilling slurry (mud). As a
manufacturer of HDD support equipment, we are well aware of the extreme conditions that HDD
equipment is exposed to on a daily basis. Surface To Surface Inc. strives to overcome these conditions,
with better design and manufacturing practices. Please feel free to call our toll free number
(1-800-567-0978) if you have any questions or concerns about your M-4.
Thank you, for choosing the M4 series mixer.
The M4 mixing unit was designed to mix dry or liquid drilling products with clean
water, into a slurry. The slurry is continually circulated through the mixing cycle until it
reaches the desired consistency. The operator can then transfer the final product to a holding
reservoir or directly to the drilling equipment.
The M4 mixing unit consists of an electric powered centrifugal pump, filter/shear unit,
venturi mixing tee assembly, dry hopper with a table, a set of tank internal jets.
These components are all mounted on a frame type skid, built for lifting or solid mounting.
For ease of interpretation, looking at the mixing unit hopper straight on will be considered
looking at the front of the unit. Hence the other long side, will be the rear and the ends will be
right or left end.

Features and Benefits M4-E Mixer
The M4-E universal mixer is designed around the time proven M series mixers of STS. Powered by a 20 hp
Teco/Westinghouse electric motor, driving a 4” centrifugal pump, it makes effective use of the proprietary 4 point
mixing system. The M4-E can be used as a new installation or retrofitted into an existing system of tank(s). Since the
unit is connected by hose and not hard pipe, the placement of the mixer verses the tank(s) is less restricted and a
configuration to suit the needs of the contractor are easier to achieve. The small size also makes it a portable,
independent unit that is easier to transport from site to site.

Description, Care and Maintenance

M4-E
Description, Care and Maintenance
Electric Powered Centrifugal Pump
Care and maintenance of the motor and pump are covered in this manual and/or the manufacturer
operator’s manuals supplied and should be read and understood. We suggest the following daily checks be
carried out prior to using the system. Visually check all electrical connections and wiring for pinches, frays
and loose or damaged parts. Check that all guards are in place and the condition of the drive coupler and
bearing block seals. Check the motor’s cooling fan cover and fins are clean and clear of debris. Check the
pump seal grease cup is full (see grease cup instructions Fig.5). Check that any water intake valve(s) are
open and the reservoir tank has sufficient liquid to supply the centrifugal pump.
The pump is connected to the motor with a drive coupler, that should be visually inspected. . The
bearings in the bearing block are factory greased to provide constant lubrication. The pump is the primary
component that will see the most wear due to the nature of the material it is handling therefore it will require
regular checks, adjustments and maintenance.
There is a section of this manual dedicated to the pump itself and should be read and understood
which will help should any problems or concerns arise in the field.
The pump should never be allowed to start or run dry, as this WILL damage the internal pump seal (grease
seal) and render the unit inoperable until the seal is fixed.
To prime the pump or check to visually see if the pump is primed, slowly undo the plug (priming
port) on top of the pump beside the discharge elbow (see Fig.4) and stop after about 3 turns. If the pump is
primed, fluid & air will escape from around the plug threads. This indicates that the pump housing is full,
and the plug can be tightened back up. If no fluid is escaping from around the threads, completely remove
the plug. Drill fluid or water can be poured into this opening to fill the pump cavity, and a visual of the fluid
level inside the pump can be made. The level should be approximately to the top of the pump housing.
Another way to prime the pump is to have the reservoir tank FULL of fluid, and standing off to the
side of the hopper, rotate the hopper valve SLOWLY to the open position. As the valve is opened, you will
hear air escaping followed by fluid, into the hopper itself. Close the valve as the fluid enters the hopper. This
means the fluid in the tank has filled the pump cavity of the pump and flowed from the outlet of the pump to
the remaining piping on the unit.
CAUTION
IMPROPER INSTALLATION OF THE
MECHANICAL or GREASE SEAL
will result in leakage and possible
damage to the seal. All maintenance,
operating and repair of this unit, must be
done per the instructions in the operators
manual for safety and reliability.
IN AN EMERGENCY
shut off all power (switch)
to halt the motor, pump, and fluid flow
DANGER
NEVER ATTEMPT REPAIRS
OR DISASSEM BLY
without shutting off the motor and
disconnect ing/lock- out t he power source.
Serious personal injury will result.

BEFORE STARTING THE MOTOR,
