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.

- 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.
