General Safety Instructions

1.  General 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 repair and 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.

NOTE:

  Before rebuilding the HOLLAND

®

 Fifth Wheel 

review the model number on the serial tag. This 
rebuild procedure applies only to the FW35TT/
XA-351-TT and FW67/XA-351-UBT elevating fifth 
wheel top plates.

IMPORTANT: 

All maintenance MUST be performed 
while the tractor is uncoupled from  
the trailer.

IMPORTANT:

  These instructions apply to the proper 

rebuild of FW35TT/XA-351-TT Series and 
FW67/XA-351-UBT elevating fifth wheel 
top plates only. There are other important 
checks, inspections, and procedures not 
listed here that are necessary, prudent, 
and/or required by law.

 

For proper installation procedures, refer to Installation 
Manual XL-FW10008BM-en-US available on the internet 
at www.safholland.us.

IMPORTANT:

  Prior to operation of the fifth wheel, verify 

that the fifth wheel has been properly 
installed on the vehicle.

Failure to properly repair and install the 
fifth wheel could adversely affect 
performance resulting in tractor trailer 
separation which, if not avoided, could 
result in death or serious injury.
