CORE AS-OIL COOLER 4L1238 - Caterpillar

Do not engage the parking brake while the machine is moving unless the primary service brake fails. The use of the parking brake as a service brake in regular operation will cause severe damage to the brake system.
When the parking brake lever is engaged the transmission is neutralized. The machine will not move.Switching the direction control lever or the direction control switch (if equipped) from NEUTRAL to either direction will not cause the machine to move until the parking brake lever is disengaged. Switching the direction control lever or the direction control switch from either direction to NEUTRAL back to either direction may cause the machine to move while the parking brake lever is engaged. Refer to Operation and Maintenance Manual, "Braking System - Test" for more information.
Moving the machine with the parking brake engaged can cause excessive wear or damage to the brake. If necessary, have the brake repaired before operating the machine.
Parking Brake - The parking brake lever is located on the left side of the seat. Use the parking brake after the machine is stopped.
