BRAKE SYSTEM Manual adjustment of automatic slack adjusters is a dangerous prac- tice that could have serious con- sequences. It gives the operator a false sense of security about the effectiveness of the brakes. Con- tact the Service Department at your dealership if the stroke exceeds the above specifications. A stroke ex- ceeding these values may indicate a problem with the slack adjuster or the brake foundation. WARNING! 5 5-70 Y53-6077-1B1 (03/17)
