TOWING A DISABLED VEHICLE
Towing a disabled vehicle should only be attempted as a
last resort, after exhausting all other options. Make every
effort to repair the vehicle, and move it under its own
power, before using the emergency towing procedures
outlined in the appropriate Owners/Operators Manual.
IMPORTANT: After the vehicle has been towed to a
secure location, reactivate the parking brake. Carefully
follow the procedures from start to finish. Consult your
local Lull distributor or the JLG service department, if
you are unsure about any part of the procedure, or for
specific instructions for your particular situation.
