The safe operation of your HDR is your responsibility. Read this manual and
the truck manufacturer’s manual and thoroughly understand them. You
can be held legally responsible for injuries or damage resulting from unsafe
operating practices.
The manufacturer’s recommendations for operating this wrecker can help
you avoid unsafe practices and their bad consequences. These
recommendations are contained in this manual.
Jerr-Dan Corporation is not responsible for the results of any unsafe practice
of wrecker operators or for the failure of the wrecker of its accessories
resulting from improper maintenance.
The danger from a vehicle does not cease when it is disabled or wrecked.
Recovering or towing vehicles can be dangerous too! The danger threatens
wrecker operators and everyone else close by. As a wrecker operator you
must develop an awareness of the hazards involved. You must use every
safeguard within reason to prevent injuries.
For each step in operating your wrecker develop the habit of asking yourself
if it is safe to proceed. Carefully check all rigging before starting a heavy lift
or pull.
We cannot warn you of all the possible dangers you will encounter, but we
will tell you of the most common hazards that we know about. We also
recommend that you receive specialized and advanced training from a
professional Towing and Recovery instructor before operating any recovery
equipment.
To alert personnel to hazardous operating practices, safety messages are
used throughout the manual. Each safety message contains a safety alert
symbol and a signal word to identify the hazard's degree of seriousness.
CAUTION:
Identifies when a potentially hazardous situation exists and may
result in a minor or moderate injury or property damage.
