a. Telescope boom to full extension.
b. Lift boom up until 1000 lb. (454 kg for ANSI markets and
450 kg for CE and Australia markets) light comes on.
c. Lift boom down using auxiliary power until 500 lb. (227
kg for ANSI markets and 230 kg for CE and Australia
markets) light comes on. Boom angle must be 45
degrees to 50 degrees (place angle indicator on base
boom between boom pivot pin and lift cylinder attach
pin).
d. Lift boom up until 1000 lb. (454 kg for ANSI markets and
450 kg for CE and Australia markets) light comes on.
Boom angle should be 55 degrees to 64 degrees.
NOTE: If limit switch settings need to be changed, you will need to
recheck that the 500 lb. (227 kg for ANSI markets and 230 kg for
CE and Australia markets) light comes on at 45 degrees to 50
degrees when lifting down.

Main Boom Length Switch.
a. Lift main boom to approximately horizontal.
b. Telescope boom out until 500 lb. (227 kg for ANSI mar-
