Safety Standard of Machinery, Equipment and Tools Article 69
An anti-kickback preventive claw for an anti-kickback device (hereinafter referred to as the anti-kickback preventive claw) or an anti-kickback preventive roll (hereinafter referred to as the anti-kickback preventive roll) shall meet the following provisions:1. Material : It is in accordance with the SS400 set the national standard CNS 2473 " the general- structure-using rolled steel " or the equivalent or others having more mechanical properties.2. Construction:(1) The anti-kickback preventive claw or the anti-kickback preventive roll shall have the function to prevent processing material from lifting on the slope tooth side of the blade and be enough strength based on the wood-piece thickness but it is unrestricted for the anti-back preventive claw with an automatic feed device.(2) For the anti-back preventive claw with an automatic feed device, it shall have function to prevent processing material kickback and be enough strength based on the wood-piece thickness.3. The support of the anti-back preventive claw or the anti-kickback preventive roll shall have sufficient strength against the processing material bounce.4. Except the circular saw with an automatic feed device, the anti-kickback preventive device with the diameter over 450 millimeters shall use that neither the anti-kickback preventive claw nor the anti-kickback preventive roll.

供反撥預防裝置所設之反撥防止爪（以下簡稱反撥防止爪）及反撥防止輥（以下簡稱反撥防止輥），應符合下列規定：
一、材料：符合國家標準CNS2473「一般結構用軋鋼料」規定SS400規格或具有同等以上機械性質之鋼料。
二、構造：
（一）反撥防止爪及反撥防止輥，應依加工材厚度，具有可防止加工材於圓鋸片斜齒側撥升之機能及充分強度。
但具有自動輸送裝置之圓盤鋸之反撥防止爪，不在此限。
（二）具有自動輸送裝置之圓盤鋸反撥防止爪，應依加工材厚度，具有防止加工材反彈之機能及充分強度。
三、反撥防止爪及反撥防止輥之支撐部，具有可充分承受加工材反彈時之強度。
四、除自動輸送裝置之圓盤鋸外，圓鋸片直徑超過四百五十毫米之圓盤鋸，使用反撥防止爪及反撥防止輥等以外型式之反撥預防裝置。
