S u p p o r t t h e l o a d b e f o re
disengaging the Rail Brake.
Failure to support the load may
result in serious injury or death.
NOTE: For faster engagement and disengagement,
install the valve close to the Rail Brake. Increasing air
pressures will also speed the disengagement time, but
do not exceed 8.3 bar [120 psi] air pressure.
The Rail Brake is equipped with one air inlet port used to
disengage the brake (Refer to Figure 2 for location).
NOTE: Clean air is important for proper Rail Brake
functioning. Debris inside the Rail Brake may inhibit
performance and/or decrease product life.
1. Route clean air to the Rail Brake using soft lines.
Supply adequate air pressure to ensure complete
disengagement.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8373.1: 2001
Class 4.4.3 quality.

CAUTION
CAUTION
Do not use rigid pipe and
tubing when making air line
connections. Doing so will
result in damage to the product
or system.
While the lubricated air will
keep the seals well lubricated,
it may wash away the factory
applied lubrication over time.
For this reason, once lubricated
air is used with a Nexen Rail
Brake, it must always be used.
Discontinuing use of lubricated
air may cause seal failure.
