The forks can be connected to the carriage by one of
two types of hooks and lock pins. See Figure 5. These
lock pins are installed through the top fork hooks and
fit into slots in the top carriage bar. Adjust forks as
far apart as possible for maximum support of load.
Hook forks will slide along the carriage bars to adjust
for the load to be lifted. Raise lock pin in each fork
to slide fork on carriage bar. Make sure lock pin is
engaged in carriage bar to lock fork in position after
width adjustment is made. See Figure 6.
