DANGER
Support the load before disengaging
the Rail Brake. Failure to support
the load may result in serious injury
or death.
NOTE: Rail brakes are factory set to fully disengage
at 4.1 bar [60 psi]. However, a supplied air pressure
of 5.0 bar [72 psi] will ensure a minimum of .05 mm
[.002”] facing clearance on each side of the rail. The
additional clearance at 5.0 bar [72 psi] will help reduce
facing drag caused by rail irregularities.
The Rail Brake is equipped with one air inlet port used to
disengage the brake (Refer to Figure 1 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.

Air-inlet Port (M5 x .8)
(use customer-
supplied air fitting)
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 6.9 bar [100 psi] air pressure.

AIR CONNECTIONS
CAUTION
Do not use rigid pipe or tubing when
connecting directly to the Brake.
Prevent unshielded air hoses from
rubbing on metal surfaces or edges,
as this will cause rapid deterioration of
the hose.
