WARNING
Since the right hand push arm is spring ­
loaded to about 100 pounds and left hand
push arm is spring-loaded to about 150
pounds, a helper is needed to release push
arms from cutting unit. Sudden release of the
push arms could cause injury.
5. Have a helper push down on the right push arm while
you remove the cap screws, flat washers, lock washers
and nuts securing ball joint mount to caster arm on
cutting unit. Now the helper can carefully allow push arm
to move upward, which will gradually release the 100
pounds of spring load.
6. Have a helper push down on the left push arm while
you remove the cap screws, flat washers, lock washers
and nuts securing ball joint mount to mount bracket on
cutting unit. Now the helper can carefully allow push arm

pounds of spring load.
