Introduction
This manual provides information necessary for the installation and
operation of the SAF-HOLLAND®CBX69 trailer air suspension
and slider system. Although the images throughout this manual
depict the CBX69, there is no difference in fit or function
between the models in the CB Series.
The CBX69 suspension includes premium 5.75" diameter axles.
For axle end and/or brake servicing information or component
replacements, refer to Drum Brake Manual XL-TA10006OM-en-US,
Disc Brake Manual XL-SA10059OM-en-US or contact Customer
Service at 888-396-6501.
This suspension uses air drawn from the tractor air system to
pressurize the air springs. The height control valve (HCV) regulates
the air pressure required for varying loads while maintaining the
design ride height. This suspension can provide a cushioned ride
throughout the load range, from empty to fully loaded.
The suspension also provides excellent side-to-side and
axle-to-axle loading which helps equalize and control braking.
Read this manual before using or servicing this product and
keep it in a safe location for future reference. Updates to this
manual, which are published as necessary, are available on
the internet at www.safholland.us.
When replacement parts are required, SAF-HOLLAND®highly
recommends the use of only SAF-HOLLAND®Original Parts.

General Safety Instructions
Operational and Road Safety Instructions
Before operating vehicle, ensure that the maximum permissible
axle load is NOT exceeded and that the load is distributed
equally and uniformly.
Make sure that the brakes are NOT overheated from
continuous operation.
Failure to minimize the use of brakes during
overheating conditions could result in
deterioration of brake efficiency which,
if not avoided, could result in death or
serious injury.
The parking brake MUST NOT be immediately applied when
the brakes are overheated.
If the parking brake is immediately applied
to the brakes when overheated, the brake
drums or discs could be damaged by different
stress fields during cooling.
Observe the operating recommendation of the trailer
manufacturer for off-road operation of the installed axles.
IMPORTANT: The definition of OFF-ROAD means driving
on non-asphalt/non-concrete routes, e.g.
gravel roads, agricultural and forestry tracks,
on construction sites and in gravel pits.
IMPORTANT: Off-road operation of axles beyond
the approved application design could
result in damage and impair suspension
system performance.
Follow the recommended routine maintenance and inspections
described in this manual. These procedures are designed so
that optimum performance and operational safety are achieved.
In the event of suspension air pressure loss, quickly reduce
speed as safely as possible and remove the vehicle from
traffic. If unable to remove vehicle from traffic, follow DOT
safety requirements regarding emergency situations.
Contact a qualified towing and/or service company to assist
in repairing the vehicle or to move it to a qualified repair facility.
DO NOT operate the vehicle in the absence of suspension
air pressure; however in the event of an air system failure
while in service, an internal rubber bumper built into the
air spring will make it possible to temporarily operate the
vehicle at reduced speed determined by road conditions.
Operating the vehicle without proper air
pressure can cause tire failure, fire, or loss
of vehicle control which, if not avoided,
could result in death or serious injury.
1. Safety Instructions
General and Servicing Safety Instructions
Read and observe all Warning and Caution hazard alert
messages. The alerts provide information that can help prevent
serious personal injury, damage to components, or both.
Failure to follow the instructions and safety
precautions in this manual could result in
improper servicing or operation leading
to component failure which, if not avoided,
could result in death or serious injury.
All maintenance should be performed by a properly
trained
technician using proper/special tools, and safe procedures.
NOTE: In the United States, workshop safety requirements
are defined by federal and/or state Occupational
Safety and Health Act (OSHA). Equivalent laws may
exist in other countries. This manual is written based
on the assumption that OSHA or other applicable
employee safety regulations are followed by the
location where work is performed.
Properly support and secure the vehicle from unexpected
movement when servicing the unit.
Failure to properly support and secure the
vehicle and axles prior to commencing work
could create a crush hazard which, if not
avoided, could result in death or serious injury.
If possible, unload the trailer before performing any
service procedures.
After re-positioning the brake chamber, slack adjuster and/
or ABS system as instructed in this manual, always consult
the manufacturer’s manual for proper operation.
Service both roadside and curbside of an axle. Worn parts
should be replaced in sets. Key components on each axle’s
braking system, such as friction material, rotors and drums
will normally wear over time.
Follow all manufacturer’s instructions on spring pressure
and/or air pressure controls.
Failure to follow manufacturer’s instructions
regarding spring pressure or air pressure
control could allow unexpected release of
energy which, if not avoided, could result
in death or serious injury.
DO NOT paint the wheel contact surfaces between the wheel
and hub.
IMPORTANT: The wheel contact surfaces MUST be clean,
smooth and free from grease.
Failure to keep wheel and hub contact surfaces
clean and clear of foreign material could
allow wheel/hub separations which, if not
avoided, could result in death or serious injury.
Only the wheel and tire sizes approved by the trailer builder
can be used.

6. Welding Standards
6.1 Scope
The SAF®suspension has been designed to be installed on a
trailer with no welding required. When welding is required for
suspension repairs, observe the requirements below. Customers
may not weld on an SAF®suspension without our prior approval,
including the application of the American Welding Society standards
by SAF-HOLLAND®engineering. This specification applies to
all components supplied by SAF-HOLLAND®, and its products.
The customer assumes all responsibility for weld integrity if
weld material and procedure differ from those listed below.
6.2 Workmanship
All welding on SAF-HOLLAND®products MUST be performed
by a welder qualified according to the appropriate AWS
standard for the weld being made or an equivalent standard.
It is the responsibility of the customer to provide good
workmanship when welding on SAF-HOLLAND®products.
6.3 Material
Items to be welded that are made from low carbon or high-strength
alloy steel are to be welded with AWS filler metal specification
AWS A5.18, filler metal classification ER-70S-3, ER-70S-6 or
equivalent unless specified on the installation drawing.
NOTE: Any substitution for filler material from the above
standard MUST comply, as a minimum, with the
following mechanical properties:
Tensile Strength - 72k psi (496 MPa)
Yield Strength - 60k psi (414 MPa)
$IBSQZ7/PUDIGUMCT/tNBUo F (-17.7o C)
% Elongation - 22%
The recommended welding gas for gas metal arc welding
(GMAW) is 90% Argon / 10% CO2. If a different gas is used,
welds MUST comply with penetration requirements illustrated
(Figure 4). Where the installation drawing specifies different
than above, the drawing shall prevail.
6.4 Procedures
Tack welds used for positioning components are to be
located in the center of the final weld, where practical. Tack
weld should be completely fused to the finish weld. DO NOT
break arc at the end of the weld. Back up all finish welds
at least 1/2" (12.7 mm) or a sufficient amount to prevent
craters at the end of the weld. Where weld is illustrated to go
around corners, it is assumed the corner represents a stress
concentration area. DO NOT start or stop weld within 1" (25.4 mm)
of the corner. Particular care should be taken to prevent
undercutting in this area.
6.5 Weld Size
If weld size is not specified, the effective throat of the weld
MUST be no smaller than the thinnest material being welded
(Figure 10).

Installation Instructions
7. Standard Air Control
System Installation
1. If NOT already present, install air reservoir, mud flap and
stinger brackets. Grind off paint and prepare all surfaces
for welding. Refer to welding standards detailed in
Section 6 of this manual.
2. Install the air reservoir to the air reservoir brackets.
3. Plumb the air control system as illustrated (Figure 11).
The air control system of the CBX69 suspension uses air drawn
from the tractor air system to pressurize the suspension’s air
springs. The suspension, working with the air control system,
provides optimum suspension performance only when all air
control system components are installed and operating properly.
IMPORTANT: Make certain that all air lines and valves
are free from obstruction through the full
operational range of the suspension.
IMPORTANT: A pressure protection valve (PPV) MUST
be attached to the air reservoir in order to
maintain proper air pressure (Figure 11).
IMPORTANT: The air pressure protection valve maintains
safe brake pressure. Approximately 85 psig
(5.9 bars) opens the valve, and 65 psig
(4.5 bars) closes the valve.
NOTE: When installing pressure protection valve, use
a drop of oil or loctite to lubricate threaded
connections. DO NOT use a pipe compound or
teflon tape as they may clog the valve.
A height control valve (HCV) is used to regulate the air
pressure required for varying load capacities (Figure 11).
Optional Air Release System
If your CBX69 was ordered with a slider pull pin air release
system, the air release control valve and the actuator will
need to be plumbed (Figure 11.A).
Optional PosiLok™System
If your CBX69 was ordered with a PosiLok™anti-dock walk
system, the PosiLok™actuator will need to be plumbed
(Figure 11.B).

4. Ensure the linkage assembled to the height control valve (HCV)
and suspension is of the appropriate height (Figure 12).
IMPORTANT: A 15" linkage is used for ride heights of
16", 16.5"-17". A 16" linkage is required
for 18" ride heights (Figure 16).
Failure to match the linkage length to the
design ride height could result in improper
suspension height which, if not avoided,
could result in damage to trailer components.
5. Connect service and emergency gland hand lines to the
slider and allow the suspension to air up.
6. Measure the ride height of the suspension (Figure 13)
with a tape measure.
7. Compare the measured suspension ride height value to
the appropriate value (Table 1). Ensure your measured
ride height value is within ±1/4" (6 mm).
IMPORTANT: If your measured ride height value is NOT
within ±1/4"(6 mm); use the table to verify
the linkage length (Table 2 and Figure 12),
and the hole location where the top mounting
stud of the height control valve (HCV) is
bolted to the mounting bracket (Figure 14).
8. Visually check all air control system fittings for air leaks
by applying a soapy water solution and checking for
bubbles at all air connections and fittings.

9. SwingAlign™Axle Alignment
IMPORTANT: Axle alignment can only be achieved if the
lockpin holes are the same distance from the
kingpin, left and right. Axle alignment should
ALWAYS be done while the trailer is empty.
9.1 Alignment Preparation
1. Pull the trailer in a straight line for a sufficient distance
to ensure there are no binds in the suspension.
2. Lock the trailer brakes and pull the trailer straight forward
so the locking pins rest against the rear of the holes in
the body rails.
3. Disengage the trailer parking brakes and ensure the
trailer is empty.
4. Manually measure or use an optical device specifically
designed for alignment measuring to determine the following:
a. Measure the distance from the king pin to
the centerline of the front axle spindles. It is
recommended that spindle extensions be utilized.
b. Dimensions A and B (Figure 15) MUST be equal to
within 1/8" (3 mm).
c. Measure the distance from the centerline of the front
axle spindles to the centerline of the rear axle spindles.
d. Dimensions C, D, E and F (Figure 15) MUST be
equal to within 1/16" (1 mm).
9.2 Alignment Instructions
1. Using the measurements from Step 4, align each axle. Align
by rotating the alignment bolt head using a 1-3/8" socket
wrench on the front face of the roadside frame bracket.
Rotate clockwise to move axle forward (A Arrows);
counterclockwise to move axle rearward (B Arrows)
- (Figure 16)"QQSPYJNBUFMZGUMCT/tNXJMM
be required.
IMPORTANT: DO NOT loosen the pivot bolt.
IMPORTANT: Two scribe lines on the side of the frame
bracket indicate maximum adjustment for axle
alignment. If the edge of the visible washer
touches either scribe line the SwingAlign™
axle alignment adjustment is “out of stroke”
(Figure 17). Inspect and repair trailer
components as necessary and realign.
IMPORTANT: The SwingAlign™design maintains proper
alignment without welding and without
loosening of the pivot connection. DO NOT
weld alignment bolt or pivot bolts
(Figure 17). If connection requires
tightening, use a 1-11/16" socket wrench

Step 6.
If lock pins fail to disengage, proceed to Step 5.
5. If the QWIK RELEASE®pull handle is in the notch 2
position but the lock pins fail to retract and are still
in the engaged position, the QWIK RELEASE®pull
arm is in an armed, ready to unlock position.
NOTE: The QWIK RELEASE®torsion spring will
automatically retract the lock pins when
the pressure on the lock pins is released.
a. Release the tractor brakes.
Failure to verify the area is clear of
others before moving the vehicle could
result in death or serious injury.
b. Gently rock the tractor and trailer fore and aft while
listening for the lock pins to disengage.
c. After the “metallic clang” of the lock pins disengaging
is heard, reset the tractor brakes, and visually verify
that the lock pins have been properly disengaged.

Operation Instructions
FLIPPER PLATE IN THE
ENGAGED POSITION
13. PosiLok™Anti-Dock Walk (Optional
Equipment)
The CBX69 suspension can be equipped with SAF®PosiLok™
which provides enhanced trailer stability during loading and
unloading operations. If the trailer air control system employs
a “spring brake priority” type arrangement, potential field
service issues may arise due to operational misuse, such as:
Moving a trailer before the air springs have been
properly inflated.
Use of yard hustler equipment.
Heavy load operations, such as paperhaul, with the slider
in the full forward position.
Engaging the emergency trailer brakes at a high rate of
speed (greater than 5 mph) to move the slider position.
Use of an auxiliary suspension dump valve with excessive flow.
Going in and out of ramped docks with slider all the
way forward.
SAF®PosiLok™system will properly support the trailer during
normal operations and is designed to bend or buckle when
subjected to overloading or other operational issues to
protect the trailer sub-frame.
The PosiLok™is engaged when the flipper
plates are in the down position.
1. Release air pressure from the trailer brake system or
disconnect the glad hand. This engages the parking
brakes and causes the PosiLok™actuator to engage,
which rotates the rod so the flipper plates swing down
into an engaged position (Figure 25).
The PosiLok™is disengaged when the flipper
plates are in the up position.
1. When the parking brakes are disengaged, the primary height
control valve (HCV) takes full function. When the system
has sufficient air pressure in the suspension air springs,
the actuator extends, rotating the rod so the flipper plates
swing up away from the load pads into a disengaged
position (Figure 26). The vehicle is now ready for movement.
IMPORTANT: DO NOT operate vehicle (put in motion) if
flipper plates are trapped in the down position
(Figure 27). Refer to the troubleshooting
section of Installation and Operation
Manual XL-AS20001BM-en-US. Available at
www.safholland.us or contact SAF-HOLLAND®
Customer Service at 888-396-6501.
Failure to adequately raise flipper
plates could result in trailer, suspension
component, and cargo damage.

Maintenance and Service Schedule
14. Routine Maintenance and
Daily Inspection
1. Daily or before each trip, check the suspension to be sure
it is fully operational.
2. Inspect all decals to ensure they are clearly legible and
intact. Clean with a terry cloth towel, soap and water.
3. Visually inspect air springs for sufficient inflation and
that the suspension is at proper ride height. For ride
height details and measurements, refer to Section 8
of this manual.
4. Inspect the slider lock pins and slider pull handle for
signs of excessive wear, bending or binding.
5. Inspect the front and rear hold down clips to ensure that
they are correctly secured around the body rails.
14.1 Initial Three (3) Months or 5,000 Mile
(8,000 km) Service Inspection
1. Suspension ride height (underside of frame to centerline
of axle) MUST be within ±1/4" (6 mm) of recommended
design height. For instructions on measuring ride height,
refer to Section 8.
An improperly set ride height could result
in suspension component damage and/or
poor vehicle ride performance.
2. After first three (3) months or 5,000 miles (8,000 km)
of service, whichever comes first, inspect bolts and nuts
at the pivot connections to ensure they are properly
torqued. Check all other nuts and bolts for proper torque,
refer to the specifications listed in Section 15. Re-torque
as necessary thereafter.
3. With the vehicle on a level surface and air pressure above
85 psig (5.9 bars), verify that all air springs are of sufficient
and equal firmness.
NOTE: Check all air control system fittings for air leaks,
by applying a soapy water solution and checking
for bubbles at all air connections and fittings.
14.2 Routine Physical Inspections
Every 100,000 Miles (160,000 km) or one (1) year, whichever
comes first.
Check all other suspension components for any sign of damage,
looseness, torque loss, wear or cracks. Repair, tighten or
replace damaged part(s) to prevent equipment breakdown.
14.3 Visual Inspection Procedure
IMPORTANT: A schedule for physical and visual inspections
should be established by the operator
based on severity of operation or damage
to the vehicle could occur.
IMPORTANT: During each pretrip and safety inspection
of the vehicle, a visual inspection of the
suspension should be done or damage to
the vehicle could occur.
Visually check for:
Loose, broken or missing fasteners. Repair or replace
as needed.
Loose, damaged, or missing fasteners
can cause loss of vehicle control which,
if not avoided, could result in death or
serious injury.
Air springs – clearances, wear damage, and proper inflation.
Shock absorbers – leaking or damaged.
Cracked parts or welds.
Also:
Check the slider locking pins, slider pull-bar mechanism
and slider wear pads for signs of excessive wear or
binding, refer to Section 11 (Figure 18). Repair or
replace as needed.
Inspect the structure of the slider box and cross members
for damage, refer to Section 11 (Figure 18). Repair or
replace as needed.
Inspect the front and rear hold down clips to make
certain the clips are secured correctly around the body
rails, refer to Section 11 (Figure 18). Torque all 1/2"
