GENERAL NOTES:
1. THE CHARTS SHOWN HEREIN ARE FOR THE REQUIRED NUMBER OF TIE DOWNS
ON THE SIDES OF THE MANUFACTURED HOME.
2. TIE DOWNS ARE REQUIRED AT EACH CHASSIS BEAM, EACH END OF)EACH
TRANSPORTABLE SECTION OF THE MANUFACTURED HOME AND CAN BE ANY
OF THE TYPES SHOWN HEREIN.
3. COMBINATIONS OF THE DIFFERENT TYPES OF TIE DOWNS CAN BE USED.
4. IN THE EVENT AN EARTH AUGER CANNOT BE INSTALLED DUE TO AN
OBSTRUCTION, USE OF CROSS DRIVE ANCHORS IS PERMITTED, PROVIDED (2)
CROSS DRIVES ARE INSTALLED FOR EACH EARTH AUGER THAT CANNOT BE
INSTALLED.
5. FOR ALL TIE DOWN INSTALLATIONS, THE MFG'D HOME CHASSIS MEMBERS ARE
SHOWN AS "I" BEAMS. FOR ILLUSTRATION PURPOSES ONLY. CHASSIS BEAMS
CAN ALSO BE "C" SHAPED OR "RFC" SHAPED.
6. END TIE DOWNS CAN BE LOCATED WITHIN 24" OF EITHER SIDE OF CHASSIS
BEAM AXIS AS SHOWN.
C` �I
18 MIN. 1
7. THE SIZES, TYPES, LENGTHS, ECT. OF MATERIAL SHOWN HEREIN ARE
MINIMUM. LARGER, LONGER, HEAVIER MATERIALS SUPPLIED BY MINUTE -MAN
PRODUCTS. MAY BE USED AT THE SAME SPACING & LOCATION SHOWN.
8. ALL PARTS ARE STAMPED MMA- WITH THE APPROPRIATE PART NUMBER.
9. THIS TIE DOWN SYSTEM CAN BE USED WITH 10' WIDE MANUFACTURED HOME
SECTIONS WITH 100" CHASSIS CENTERS PROVIDED THE HEIGHT FROM GRADE TO
THE BOTTOM OF THE CHASSIS BEAM DOES NOT EXCEED 19".
10. TIE DOWN STRAPS IN THE LONGITUDINAL OR TRANSVERSE DIRECTION CAN BE
BOLTED TO THE HITCH ATTACHMENT PLATE THAT IS WELDED TO THE CHASSIS BEAM.

INSTALLATION INSTRUCTIONS
FIRST CHECK FOR UNDERGROUND UTILITY LOCATION:
EZDH EARTH AUGERS
1. SEE DETAIL THIS BOOKLET FOR INSTALLATION INSTRUCTIONS.
EARTH AUGERS
1. INSTALL AUGERS INTO SOIL WITH CONSTANT DOWNWARD PRESSURE TO MINIMIZE SOIL DISTURBANCE
LEAVING APPROX. 12" OF SHAFT EXPOSED.
2. INSTALL STABILIZER PLATE - DRIVE FLUSH WITH GROUND SURFACE.
3. COMPLETE TURNING AUGER INTO GROUND UNTIL AUGER HEAD IS FLUSH WITH GROUND SURFACE AND TOP
OF STABILIZER PLATE.
CROSS DRIVE ANCHORS
1. CROSS DRIVES ARE USED WHERE HARD ROCKY SOIL OCCURS. IF THE GROUND SURFACE IS OTHER THAN
ROCK OR - MIN 2.5" ' ASPHALT, INSTALL MMA-SD2 STABILZER PLATE, OR PLACE 12"x12"x12" DEEP CONCRETE.
CONCRETE SLAB ANCHORS
1. CONCRETE SLAB TO BE MINIMUM 3 1/2" THICK AND IN GOOD CONDITION.
2. MINIMUM SLAB AREA REQUIRED FOR EACH ANCHOR IS 28 SQ. FEET.
3. DRILL PROPER SIZE HOLE IN SLAB MINIMUM 4" FROM ANY EDGE.
ALL APPLICATIONS
1. ATTACH STRAPS TO CHASSIS BEAM IN MANNER SHOWN.
2. INSERT STRAP THROUGH SPLIT NUT, CUT OFF EXCESS STRAP AND TIGHTEN UNTIL SNUG.
THIS PLAN MAY BE USED FOR MANUFACTUED HOMES PLACES IN FEMA FLOOD HAZARD
ZONES A, AE & AH, PROVIDED THE GROUND ANCHORS ARE THE MMA -650, 50" EARTH
AUGERS. UNDER FLOOR VENTS AT THE PERIMETER SKIRTING SHALL BE PLACED WITH
THE BOTTOM OF THE VENT MAX 12" ABOVE THE UNDER FLOOR GROUND SURFACE

INSTALLATION INSTRUCTIONS
1. THE DRIVE MACHINE IS STARTED AND THE ANCHOR IS TURNED INTO THE GROUND TO A POINT WHERE THE TOP
(STABILIZER HEAD PLATE) IS FLUSH OR SLIGHTLY BELOW GROUND LEVEL. THIS INSURES THAT THE E -Z ANCHOR
STABILIZER WILL BE AT ITS REQUIRED INSTALLATION POSITION.
2. FOR THE E -Z ANCHOR/STABILIZER TO ACHIEVE FULL POTENTIAL, INSTALL THE ANCHOR VERTICALLY WITH NO
DEVIATION GREATER THAN 10 DEGREES. NOTE: A SLIGHTLY GREATER ANGLE MAY BE USED TO START THE
ANCHOR TO AVOID CONTACT WITH THE HOME & STRAIGHTENED AS THE ANCHOR IS GROUND SET.
THE SPLIT BOLT IS INSERTED, STRAP FASTENED, AND TIGHTENING ADJUSTMENT MADE.
NOTE: WITH MACHINE INSTALLATION, A MINUTE -MAN ADAPTER DESIGNED TO FIT BOTH THE ANCHOR HEAD
AND DRIVE MACHINE SHAFT IS AVAILABLE. INSTALLERS DO NOT NEED ADDITIONAL OR SPECIAL EQUIPMENT
FOR E -Z ANCHOR INSTALLATION.
