BLADE II SAW: SAFETY General Warnings WARNING HIGH VOLTAGE ELECTRICITY! May cause serious personal injury or death. Ensure only qualified electricians perform electrical service work. WARNING Read the equipment manual, safety labels, and all safety information provided before operating or maintaining this equipment.
Page 15: Lockout/Tagout
BLADE II SAW: SAFETY Lockout/Tagout Lockout/Tagout Guidelines Lockout/tagout all energized systems before performing maintenance on them. All lockout/tagout guidelines must be met according to OSHA 29 CFR 1910.147. A specific procedure should be included in your company’s energy control program. This manual is not intended to replace your company’s de- energizing or lockout/tagout procedure required by OSHA, but merely to provide general guidance.
Page 16 BLADE II SAW: SAFETY Electrical Lockout/Tagout Procedures Working on a Machine Outside the Machine’s Main Electrical Enclosure If you are working on the electrical transmission line to the machine, follow the procedure on page 8. Before performing maintenance on any machine with electrical power, lockout/ tagout the machine properly.
Page 17: Electrical Lockout/Tagout Procedures
