13. Always secure the steeringwheel with a steering wheel strapfor any front or rear tow.

14. With the vehicle in neutral andthe parking brake released, youcan move the vehicle safely up,down, in or out. All of thesemovements are hydraulicallycontrolled.

15. Power retract the under lift untilthe casualty vehicle is aboutthree (3) to four (4) feet from theback of the recovery vehicle.Leave enough room to maneuveraround corners without cornerbinding or causing contactbetween the two (2) vehicles. Besure that the fly boom isextended at least four (4) in.from the middle boom sectionto ensure unobstructed cross-bar pivoting.

16. Raise the casualty vehicle into towing position observing the far end forsufficient ground clearance. It is possible to set the rear of a front liftedvehicle completely onto the ground, causing damage. Take irregularroad surfaces into consideration.

NOTE:

When towing, the Underlift Boom should be as close to horizontalas possible. You will have better turning and manueveringcapabilities and it will prolong the life of your under lift and pivotpin.

CAUTION:The tire lift and grid tubes must be in their outermost positions forstorage on the under lift when folded up in the travel position toavoid damage to the body.

CAUTION:Retighten the tie-down straps periodically during a tow as the tiressettle into the grid from towing.

5-376-000037REV. 6 - 03/08

OperationPage 8

CAUTION:

The use of secondary tie-down chains is recommended. Fit thesecondary tie-down chains to the axle (not to any part of thesuspension or body which will rise and fall with the suspension)arranged so as to hold the wheel down in the grid and prevent itfrom jumping up, forwards, or backwards. Use load binders asrequired.

CAUTION:The use of trailer brakes or secondary braking devices while towingis recommended.

CAUTION:Do not tow any vehicle without safety chains being installed.

CAUTION:

Always follow the chassis manufacturer's recommended proceduresfor towing. Remove drive lines and drive shafts as directed. Manyvehicles can be severely damaged unless these components areremoved prior to towing.

CAUTION:

All products are subject to age, wear and deterioation, all of whichcause a reduction in the products breaking strength capacity. It isrecommended that all products be regularly inspected. Any worn,deformed, misused or overloaded products should be replacedimmediately.
