WARNING ONLY &XPERIENCED PERSONS KNOWLEDGEABLE OF MANUFACTURED HOME SETUP PROCEDURES SHOULD SET UP THIS HOME. WHEN SETTING UP THIS HOME, THE FOLLOWING PRE- CAUTIONS REGARDING JACKING MUST BE FOLLOWED: 1, Before doing any jacking, place support piers for the home in the locations under the home as specified in the home installation instructions. The experienced person setting up this home should be familiar with the National Fire Protec- tion Association Standard for Manufactured Home Installa- tions, NFPA No, 501A and the Manufactured Home Installa- tion Instructions. 2. Use a minimum of two jacks, each with a rating of at least five tons. 3. Jack only on the main chassis I-beam. Locate the jack directly under the vertical web of the I-beam. Do not jack on the seam Ooint between flanges) of a twin I-beam. 4. Use a large 3/8 inch thick steel plate, C-channel or other equivalent plate between the main chassis I-beam and the jack head to distribute the load. 5. The jack base, and any blocking must be located on firm ground. 6. Dc not operate the jacks while you are under the home. 7. Use jacks only for raising the home. Do not rely on the jacks to support the home. 8. Raise the home in small increments and provide additional blocking between the home and the piers as the home is raised. 9. Do not go under the home while it is supported on the jacks. FAILURE TO FOLLOW THESE WARNINGS MAY RESULT IN SERIOUS INJURY OR DEATH. Reminders before jacking... 1, Use only jacks in good condition with a minimum rating of 5 tons. 2. Use a steel plate (%" x 21/2" X 5") or hardwood block (4" x 4" x 12") between jack and steel ''1'' -beam to distribute the concentrated loads. (See Figure 1) 3. Use a firm support under the jack base to prevent tipping or settling of the jack. 4. Always follow the sequence of jacking outlined below to avoid overstressing structural members. The jacking procedure is as follows: 1. After the home is located in its final position, you can preliminarily level it by using the hitch jack but oniy after ade- I or-BEAM < '-3;8 X 2}iX 5" STFl:'1 PLATE 5 TON JACI< BLOCKING PROCEDURE quately blocking the home. 2. Jack up one side of the home by placing one Jack jus: forward of the front spring hanger and the other just behind the rear spring hanger. These two .iacks must be operated simultaneous- ly to raise the home. Install footings and piers: one JUst forward of the front jack and another just behind the rear jack (taking care not to exceed the correct spacing selected trom Table 1 or 2). 3. Next,iack the main "I" -beam at the front and position a pier within 1 - 0" of the end of the ''!'' -beam. At the completion of this step, this side ot the home should be approximately level. 4. Repeat Steps 2 and 3 for the other side of the home. At the completion of this step, the home should be roughly level from front to rear and from side to side. 5, Place the remaining pier supports under the main "I" -beam on each side taking care to maintain a maximum distance of no more than the spacing determined from Tables 1 or 2 with piers located within l' - 0" of each end of each "I" -beam. (See Fig. 2) 6. Level the home within reasonable tolerances, using a 6 foot carpenter's level, water level, or similar equipment. The final height adjustment is obtained by jacking the "I" -beam and placing hardwood shims between the piers and "I" -beam, or other approved methods such as adjustable piers. THIS LEVEL- ING PROCESS IS IMPORTANT FOR APPEARANCE AND IS ESSENTIAL FOR THE PROPER OPERATION OF DOORS, WINDOWS, AND THE DRAINAGE SYSTEM. 7. Within 90 days after initial set-up, the home should be relevel- ed, if necessary, to compensate for any pier settlement. Follow the procedure in Item 6 above.
