Figure 1-6. Press and hold the brake release button to
move the arm. When you release the button, the brakes
will re-engage and hold the arm stationary.
NOTE
There are two
holes in the arm
extension for the locking pin,
one at each end. Do not hold
the pin when you are sliding
the extension out. The pin
snaps into the hole to prevent
the extension from coming all
the way out of the arm.

the locking knob counter-clockwise and pull out the
locking pin. Pull the arm extension out to the position
you want, then tighten the locking knob to secure it.
When you pull the extension out to the end of travel,
the locking pin will snap into the hole at the end of the
extension.
