Hazard Alert Messages
8 Maintenance
Read and observe all Warning and Caution hazard alert messages in
this publication. They provide information that can help prevent
serious personal injury, damage to components, or both.
WARNING
To prevent serious eye injury, always wear safe eye protection
when you perform vehicle maintenance or service.
During lubrication procedures, if grease flows from the seal
near the camshaft head, replace the seal. Remove all grease
or oil from the camshaft head, rollers and brake linings.
Always replace linings contaminated with grease or oil, which
can increase stopping distances. Serious personal injury and
damage to components can result.
ASBESTOS AND NON-ASBESTOS
FIBERS WARNING
Some brake linings contain asbestos fibers, a cancer and lung
disease hazard. Some brake linings contain non-asbestos
fibers, whose long-term effects to health are unknown. You
must use caution when you handle both asbestos and
non-asbestos materials.
