INTRODUCTION
This manual provides you information necessary for the
installation, adjustment, inspection, and safe operation of the
Holland air release feature for Trailer Sliding Suspensions.
No more pulling. New Air release effectively retracts and engages
slider pins with the pull/push of a knob. For added simplicity,
the Air Release operates with a proven design air brake chamber
just like current braking systems.
NOTES, CAUTIONS,
AND WARNINGS
You must read and understand all of the safety procedures
presented in this manual before starting any work on
the suspension.
Proper tools must be used to perform the maintenance and
repair procedures described in this manual. Many of these
procedures require special tools.
No training is required and faster slide relocation is enabled by
the simple switch operation.
Failure to use the proper equipment could result in
personal injury and/or damage to the suspension.
To adjust the slide, the driver must park on level ground and set
all the brakes.The driver reloactes the stop bar to the desired
location and pulls out the Air Release knob located on the front
of the slider. The air brake chamber then releases the pins and
locks in the out position to allow movement.When pins have
released the driver slowly repositions the tractor until slide
contacts the manual stop bar. Set tractor brakes after positioning
is complete. Push in the knob and pins automatically engage and
lock into place.
Safety glasses must be worn at all times when
performing the procedures covered in this manual.
The driver must check to ensure lock pins extend through upper
rail.As an added measure of safety, the stop bar must be relocated 1 hole behind slider before operating the vehicle.
For added driver safety, the Air Release only works when the
parking brake is set and is connected to the air supply with a
valve to prevent draining.
Air Release is available on all models of Holland slides - new and
retrofit. Optional manual back up also is available.

NOTE:
The pull handle must be removed from the slider
frame prior to the Air Release installation.
2.
For a CB400/4000 suspension locate the actuator chamber
bracket and weld in place as shown in FIGURE 3. For a
mechanical suspension locate the actuator chamber bracket
as shown in FIGURE 4.
3.
Locate the Spring Brake Cam as shown in FIGURE 3 and
FIGURE 3A for the CB400/4000 and tack weld in place. If
you have a Mechanical Suspension, refer to FIGURE 4 and
FIGURE 4A.
NOTE: The spring brake actuator rod and clevis should be
horizontal when attached for the CB400/4000
Suspension. Pay close attention to the spring brake
cam angle prior to finish welding.The cam pin must
be lower than the tube for ease of rotation proper
