PROCEDURES

Before entering the vehicle or vehicle body,
read and follow OSHA regulations concerning
entry and working in “CONFINED SPACE”
OSHA 1910.146 and “LOCKOUT/TAGOUT”
OSHA 1910.147. Follow OSHA regulations
while performing any work on the vehicle. The
vehicle must be disabled by the following steps
before performing any work on the vehicle:
1. Place the transmission in NEUTRAL.
2. Set the parking brake.
3. Shut the engine OFF.
4. Lock cab doors, keep the key in your
