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 

could 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.
