Store flat and keep dry and covered prior to
installation. Installing siding wet or saturated may
result in shrinkage at butt joints. Carry planks on
edge. Protect edges and corners from breakage.
James Hardie is not responsible for damage caused
by improper storage and
handling of the
product.
OUTDOORS
1. 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.

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.

• HardiePanel vertical siding may be installed on flat vertical wall applications only.
• For larger projects, including commercial and multi-family projects, where the span of the wall is significant in length,
the designer and/or architect should take into consideration the coefficient of thermal expansion and moisture
movement of the product in their design. These values can be found in the Technical Bulletin “Expansion Characteristics
of James Hardie
®
