4.1 

KNOW THE RULES & YOUR EQUIPMENT.

Most job sites have rules governing equipment use & maintenance. 
Before starting at a new work location, check with the supervisor or 
safety coordinator. Ask about any rules or regulations you need to 
abide.

OSHA enforces federal laws within the United States that apply to the 
safe operation, application, & maintenance of equipment on job sites. 
It is the employer’s responsibility to comply with these laws. 

Do not operate this machine unless you have read the operations and 
maintenance manual carefully.

Do not operate this machine unless you have received operational and 
maintenance training from a U.S.SAWS representative or from an autho-
