Safety Standard of Machinery, Equipment and Tools Article 50
A hand-fed planer except a portable shall have a cutter contactpreventive device complying with the following provisions. It might be exempted from a part or all of them if it has equivalent or more performance accredited from the inspection agency.1. It has a guard to cover the portion except the wood-piece being planned.2. It has strength to withstand deflection and distortion.3. It has function to prevent bolts, pins and others of the hinge in a self-adjusting contact-preventive device from loosening or dropping out.4. A self-adjusting contact-preventive device shall be used for those pushing a wood-piece by hands. If most wood-pieces with a same form, a same planning width and no risk of hands contacting with the shaper, a fixed cutter contact-preventive device can be used too but it is unrestricted for the cutter contactpreventive device used in a spindle shaper.The cutter contact-preventive device for the hand-fed planer shall make the gap between the low-edge of a cover and a material-fed table be less than 8 millimeters.

攜帶用以外之手推刨床，應具有符合下列規定之刃部接觸預防裝置。
但經檢查機構認可具有同等以上性能者，得免適用其之一部或全部：
一、覆蓋應遮蓋刨削工材以外部分。
二、具有不致產生撓曲、扭曲等變形之強度。
三、可動式接觸預防裝置之鉸鏈部分，其螺栓、插銷等，具有防止鬆脫之性能。
四、除將多數加工材料固定其刨削寬度從事刨削者外，所使用之刃部接觸預防裝置，應使用可動式接觸預防裝置。
但直角刨削用手推刨床型刀軸之刃部接觸預防裝置，不在此限。
手推刨床之刃部接觸預防裝置，其覆蓋之安裝，應使覆蓋下方與加工材之進給側平台面間之間隙在八毫米以下。
