SUPPLEMENTAL WARNINGS
The following are commercial warnings from Chapter 1l. These are subject to copyright protection and will
not always conform to the Government’s standards.
WARNING
AUTOMATIC SLACK ADJUSTERS
• Make sure the wheels are chocked before servicing the semitrailer. Release the parking brake and check that
the push rod is fully released. If the push rod is not fully released, the ASA cannot be installed properly.
Semitrailer movement may cause injury or death to personnel and damage to the equipment.
• DO NOT use an impact wrench or permanent internal damage will occur!
WARNING
BEARING REMOVAL AND INSTALLATION
Do not use compressed air to spin bearing rollers as injury to personnel may result if cage does not retain the
rollers.
WARNING
ENHANCED EASY-STOP TRAILER ABS WITH PLC
• To prevent serious eye injury, always wear safe eye protection when you perform vehicle maintenance or
service.
• The ABS is an electrical system. When you work on the ABS, take the same precautions that you must take
with any electrical system to avoid serious personal injury. As with any electrical system, the danger of
electrical shock or sparks exists that can ignite flammable substances. You must always disconnect the battery
ground cable before working on the electrical system.
• Release all pressure from the air system before you disconnect any components. Pressurized air can cause
serious personal injury.
• You must use a Schedule 80 hex nipple (3/4 in. NPTF) to mount the ECU/single modulator valve assembly
securely to the air tank to avoid possible serious personal injury and damage to the component.
WARNING
KINGPIN MAINTENANCE AND REPLACEMENT RECOMMENDATIONS
When welding, use a procedure which assures a sound, good quality weld which protects the welding
operator and others. Overwelding may cause distortion and damage and underwelding may not develop
sufficient strength. A low hydrogen process and AWS 370XX filler metal are recommended. Take
precautions to ensure that the vehicle electrical system is not damaged by the welding.
WARNING
LANDING GEAR
Ensure the landing leg scissor assembly retaining (locking) pins do not present a contact hazard to
personnel. The pins can extend outward and cause injury to personnel.
