Failure to follow jacking wamings and procedures may result in �° Hun MHCsSS serious injury or death. Please read the Jacking Safety Precautions before lifting the 1/15/09 home with jacks. • No one should be under the home's I-beams while the jacks are being oper- ated perated or while the home is supported only on the jacks. • Use jacks only for raising the home.Do not rely on the jacks to support the home. • If possible, raise the home only on one side so that the other Side is in contact with the ground.Leave the hitch connected to the vehicle or other stabilizing equipment. • Obey all OSHA regulations. • Make sure adequate safety cribbing(Figure 17)is in place whenever the home is placed on jacks. • Use a minimum of two commercial quality jacks,each with a rating of at least 12 tons. • Jack only on the main chassis I-beam,centering jacks directly under the beam. • Do not jack on a seam(joint between flanges of twin I-beams). • To distribute'the concentrated loads from jacks to i-beam,place a minimum 318-inch'thick steel plate,a C-channel,;a 11/2-inch'thick hardwood block or a • commercial jacking plate,between the main chassis I-beam and the jack head. • Locate the jack base on firm ground.Never jack on freshly disturbed soil or where an underground sewer pipe may be located. • Use a firm support under the jack base to prevent tipping or settling of the jack.. A minimum 16"x 16"or larger wood or rigid fiberglass pad is recommended. Never use concrete blocks as a support for a jack. Follow the jacking sequence outlined below to avoid overstressing structural members: 1. Block wheels. Block the wheels so the house does not roll. 2. Install cribbing. Install safety cribbing(Figure 17). Figure 17.Stack 4"x 6"by 5' fl ' ' - '• long timbers as shown to form r-" safety timbers.

Locate one jack at the hitch and level the section length- 0— wise wise(such that the front and rear of the section are at the same height). 4. Locate frame jacks. Place a minimum of one jack just forward of the first to spring hanger and another just behind the last spring hanger of the I-beam on the side of the home that is lowest(making sure not to place jacks where the piers will go). Place jacks no more than 20 feet apart and no more than 20 feet from each end of the I-beam. 5. Lift the home.Operating the jacks simultaneously(or sequentially in very small increments), lift the home section until it is slightly higher than the final desired pier height. z ROLLER SYSTEMS When using a roller system,comply with the equipment manufacturer's directions and the following sequence: 1/9/2009 9:22 Ali Skyline Corporation (4-48 PG. 1) 31 PFS certifies this document is current as of 12-16-09. , V•:.\\,,wN‘4, • 1.

Roll home.Roll the home into place over the foundation. 5. Remove bump blocks.Remove the blocks before installing the next section of a multi-section home. CRANES When using a crane,follow these guidelines: • Position the home section(s)and crane(taking the boom reach into consid- eration)such that they do not have to be repositioned during the set. • Use enough properly sized straps to maintain balance of the home and to prevent damage to the structure. • Place straps under walls or posts,including temporary posts used to support the opening. Do not position lifting straps under marriage wall openings. • Use a properly sized spreader bar to maintain a vertical lift,to avoid placing compression forces on the eaves and to reduce any tendency to slip. • Connect a rope to at least one point on the home so it can be controlled while aloft. • Make provisions to retrieve the straps/cables after the home is set. If using a cradle system, notch the sill plate where the straps will fall. For a sling sys- tem, notch and reinforce the home's rim joist to keep the strap from slipping and allow the strap to be removed after the home is set. • Always set the home section farthest from the crane first so that subsequent section(s)need not be lifted over previously set sections. \‘‘ Q,vN ;• kr•Vi. 2,1 , yk,\ STEP 4.

DETERMINE TIE-DOWN CONFIGURATION There are two primary tie-down configurations:the near beam and the far beam meth- ods. Skyline Corporation use the near beam method for all Wind Zone I applications. The near beam method is also used at Wind Zones II and III,except when a unit has a 5 • in 12 roof pitch,and then the far beam method is used. The two methods are described below: • • Near Beam Method.Connect an anchor strap from the anchor head to the beam closest to the anchor.(Figure 71). In addition for Wind Zones II and II, connect a vertical sidewall strap from the sidewall of the home to the anchor head using a double-headed anchor. • Far Beam Method. Connect an anchor strap from the anchor head to the out- side beam.(Figure 71). In addition for Wind Zones II and II,connect a vertical sidewall strap from the sidewall of the home to the anchor head using a double- headed anchor. The far beam method is only required for double wide units at Wind Zone II or III with a 5/12 roof pitch.

Configure skirting.Run the skirting along the perimeter of the home's heated,conditioned space. Do not enclose with skirting areas under recessed entries,porches,or decks(whether constructed as part of the home or added on site)unless skirting is of the fully vented type and installed so as to allow water to freely flow out from under the home. 2. Fasten skirting.Recess the skirting under the siding or trim and attach it to the home in a manner that prevents water from being trapped between the siding or trim and the skirting. For wood,aluminum,or fiberglass skirting, in- stall a skirt rail (lumber strip)under the floor inset at least 1-1/2 inches from the edge of the siding for attachment of the skirting.Allow for frost heave when installing skirting in areas subject to frost. 3. Provide ventilation. Unless the skirting has integral ventilation openings that meet the following ventilation requirements,install equally sized ventilation openings on at least two opposite sides of the foundation.Size ventilation area to equal at least one square foot or each 150 square feet of under-floor area(or for each 1,500 square feet if a ground moisture retarder is installed according to STEP 2. INSTALL GROUND MOISTURE RETARDER, p.96). Place vents as high above the ground as practical. 4. Install access. Provide an access opening not less than 18 inches wide and 24 inches high and located so that any utility connections located under the home are accessible. 5. Extend vents,drains,and inlets. Run appliance exhaust vents,combustion air inlets,and air conditioner condensation drains through the skirting to the —I outside and terminate each as instructed in the sections of this manual corre- sponding to each appliance. STEP 4. ASSEMBLE OPTIONAL WIND PROTECTION SHUT- TERS r- If desired, prepare temporary protective window covers for use during severe wind storms and hurricanes according to Figure 97,Table 27,and the procedure below. 1. Assemble extension framing using with two 16d common nails at each con- nection. 2. Assemble shutter panels as shown in Figure 97. 3.
