The IHMEE is fitted with a parking brake system that is
spring-operated and locks all four wheels. The PARK
BRAKE lever is mounted on the console on the right side
of the operator's seat.
To engage the parking brake, move PARK BRAKE
lever (1) from OFF to ON and simultaneously raise lever
to hold it in locked position.
The IHMEE is fitted with a separate proportional braking
system for use when towing a trailer. When a trailer is
attached to the IHMEE, trailer service brakes are coupled
to the vehicle's foot brake and parking brake. Normal
operation of the foot brake causes the trailer service
brakes to be applied at the same time. Use of the IHMEE
parking brake also applies the trailer's service brakes.
The trailer parking brakes are operated using a
spring-loaded lever, attached to the front of the side
console. To prevent the trailer from overrunning the
IHMEE, the trailer parking brakes should be applied
before the vehicle brakes are applied. The trailer parking
brakes may also be used to slow the vehicle on long
declines.
To activate the trailer brakes, move TRAILER
EMERGENCY BRAKES lever (1) to ON position.
