Introduction
Congratulations on your purchase of a MaddogTM Mixer - the world’s best portable
cement mixing system - designed specifically for mixing various types of aggregate by
the construction professional!
The MaddogTM portable mixing system comprises a unique, portable hand-held cement
mixer that integrates with a specialized tub and can thoroughly mix cement, grout, stucco
and mortar quickly and easily at virtually any job site. The MaddogTM mixing system is
available in both a gas-powered and electric-powered models.
The MaddogTM portable mixing system offers a complete portable “mixing system”
(MPMS) that combines the portability and performance of a hand-held aggregate mixer
and a specially designed mixing tub that acts as a convenient carrying case. The entire
system weighs less than 40 pounds and can fit in the bed of a truck, or the trunk or back
seat of most sedans. The tub’s design allows for precise batch mixing of all types of
bagged aggregate and specialty materials commonly found in the construction trades.
Consistent blending of materials is achieved through the interaction of the unique mixing
blades and the shape of the interior of the mixing tub.
The MaddogTM portable mixing system has the ability to adapt to the size of the mixing
job through either the rapid replenishment of mix in the tub, or the utilization of
additional tubs, such that one tub is being poured while the additional tub is being mixed.
The ability to more precisely match the amount mixed with the demands of the job
enables MaddogTM portable mixing system to provide an immediate cost reduction and
labor savings to the end user. Extensive marketing and field research has shown that the
MaddogTM portable mixing system fills an important niche between two existing mixing
technologies: the inexpensive, but very unproductive paddle mixers and the far more
expensive traditional tow-behind drum mixers that most contractors detest.
The MaddogTM portable mixing system provides a truly simple, but unique design
concept that will absolutely revolutionize the cement mixing world.

Operating Instructions
Now you’re ready to use your Maddog™ Portable Mixing System. Watch the
instructional video on the website at www.MaddogMixer.com
Special Mixing Note: Always add the water into the
tub BEFORE adding your dry materials. If the dry
ingredients are added first, you may have
inconsistent mixing with unmixed materials at the
bottom of the tub.
With the engine running, and both hands on
the handles, squeeze the throttle trigger
gradually to increase the engine speed and
engage the blades. NOTE: This step must
be repeated each time your mixer trigger is
released.
Maddog™ is designed so the blades naturally pull the mixer forward in the mixing tub.
Simply glide the mixer back and repeat this forward and back motion until your materials
are thoroughly mixed.
