USERS MANUAL
This owners manual is written to familiarize opera-
tors with the safe and efficient operation of the Chief
EZ Liner S21M System. The S21M machine features
a unique multiple/simultaneous pulling method to
return the vehicle’s damaged structure and sheet
metal to its original position.
The S21M feature three towers at the front, with the
capability of adding one or two optional towers at the
rear providing 360 degree access to the vehicle. The
machine tilts hydraulically for either drive on or
winch positioning of the vehicle.
The S21M is Chief ’s new “millennium” edition. Like
the S21 system, each tower features a 10 ton hydraulic
cylinder with a 10 inch stroke. The cylinders in the
S21M system; however, feature a larger diameter pis-
ton.
