Position cutting station so that airﬂow blows dust away from the user and others near the cutting area.2. Cut using one of the following methods: a. Best: Circular saw equipped with a HardieBlade® saw blade and attached vacuum dust collection system. Shears (manual, pneumatic or electric) may also be used, not recommended for products thicker than 7/16 in. b. Better: Circular saw equipped with a dust collection feature (e.g. Roan® saw) and a HardieBlade saw blade. c. Good: Circular saw equipped with a HardieBlade saw blade. INDOORS DO NOT grind or cut with a power saw indoors. Cut using shears (manual, pneumatic or electric) or the score and snap method, not recommended for products thicker than 7/16 in. - DO NOT dry sweep dust; use wet dust suppression or vacuum to collect dust. - For maximum dust reduction, James Hardie recommends using the “Best” cutting practices. Always follow the equipment manufacturer’s instructions for proper operation. - For best performance when cutting with a circular saw, James Hardie recommends using HardieBlade® saw blades.- Go to jameshardiepros.com for additional cutting and dust control recommendations. CUTTING INSTRUCTIONS STORAGE & HANDLING: IMPORTANT: The Occupational Safety and Health Administration (OSHA) regulates workplace exposure to silica dust. For construction sites, OSHA has deemed that cutting ﬁber cement with a circular saw having a blade diameter less than 8 inches and connected to a commercially available dust collection system per manufacturer’s instructions results in exposures below the OSHA Permissible Exposure Limit (PEL) for respirable crystalline silica, without the need for additional respiratory protection. If you are unsure about how to comply with OSHA silica dust regulations, consult a qualiﬁed industrial hygienist or safety professional, or contact your James Hardie technical sales representative for assistance. James Hardie makes no representation or warranty that adopting a particular cutting practice will assure your compliance with OSHA rules or other applicable laws and safety requirements. RES20-0116 GENERAL FASTENING REQUIREMENTS Fasteners must be corrosion resistant, galvanized, or stainless steel. Electro-galvanized are acceptable but may exhibit premature corrosion. James Hardie recommends the use of quality, hot-dipped galvanized nails. James Hardie is not responsible for the corrosion resistance of fasteners. Stainless steel fasteners are recommended when installing James Hardie® products near the ocean, large bodies of water, or in very humid climates. Manufacturers of ACQ and CA preservative-treated wood recommend spacer materials or other physical barriers to prevent direct contact of ACQ or CA preservative-treated wood and aluminum products. Fasteners used to attach HardieTrim Tabs to preserva- tive-treated wood shall be of hot dipped zinc-coated galvanized steel or stainless steel and in accordance to 2009 IRC R317.3 or 2009 IBC 2304.9.5 • Consult applicable product evaluation or listing for correct fasteners type and placement to achieve speciﬁed design wind loads. • NOTE: Published wind loads may not be applicable to all areas where Local Building Codes have speciﬁc jurisdiction. Consult James Hardie Technical Services if you are unsure of applicable compliance documentation. • Drive fasteners perpendicular to siding and framing. • Fastener heads should ﬁt snug against siding (no air space). • NOTE: Whenever a structural member is present, HardiePlank should be fastened with even spacing to the structural member. The tables allowing direct to OSB or plywood should only be used when traditional framing is not available. HardieSofﬁt® Panels SF1204 P2/3 04/19 Figure 5 • For wood frame construction a minimum 4d common nails spaced 8 in o.c. at panel edges and intermediate framing members spaced up to 24 in on center are suitable in most locations*. • For conventional 20ga - 16ga steel frame construction a minimum No. 8-18 x 0.323 in HD x 1 in long ribbed bugle screws spaced 6 in o.c. at panel edges and intermediate framing members spaced up to 24 in on center are suitable in most locations*. *Minimum Basic Wind Speed differs by locality. Where speciﬁed levels of wind resistance are required, refer to applicable Building Code Compliance Reports. FASTENER REQUIREMENTS Figure 6 Self-adheringmembrane Step flashing Housewrap Drip edge Kickoutﬂashing Self-adheringeaves membrane Because of the volume of water that can pour down a sloped roof, one of the most critical ﬂashing details occurs where a roof intersects a sidewall. The roof must be ﬂashed with step ﬂashing. Where the roof terminates, install a kickout to deﬂect water away from the siding. It is best to install a self-adhering membrane on the wall before the subfascia and trim boards are nailed in place, and then come back to install the kickout. KICKOUT FLASHING Figure 6, Kickout Flashing To prevent water from dumping behind the siding and the end of the roof intersection, install a "kickout" as required by IRC code R905.2.8.3 : “...ﬂashing shall be a min. of 4” high and 4” wide.” James Hardie recommends the kickout be angled between 100° - 110° to maximize water deﬂection PNEUMATIC FASTENING James Hardie products can be hand nailed or fastened with a pneumatic tool. Pneumatic fastening is highly recommended. Set air pressure so that the fastener is driven snug with the surface of the siding. A ﬂush mount attachment on the pneumatic tool is recommended. This will help control the depth the nail is driven. If setting the nail depth proves difﬁcult, choose a setting that under drives the nail. (Drive under driven nails snug with a smooth faced hammer - Does not apply for installation to steel framing).
