  trAled by the boom, stick, grapple, and
  stabilizer con- trol levers mounted on the
  operator's platform.

OPERATING SUGGESTIONS A control lever operating
diagram (shown on Page 2) is located in fro nt of
the control levers. Study this diagram car efully
to become familiar w ith the con- trol s IM PORTA
NT W hen wo rk ing I he Knuc kl eboo m Loader
for the first time, become familiar with its op-
eration. Drive the truck to a safe open area free
of obstructions and overhead wires. Lower both
stabiliz- ers to the working position. Operate
the control levers slowly at first. Remem- ber
that two levers can be used at the same time.
Note that the speed of the cylinder movement de-
pends on how far the control lever is moved.
Operate all functions sever al times before doing
any actual loading. For a sMOOth, safe, efficient
operation, deve- Iop an operatin g technique that
utilizes two or more functions at the same
time. Avoid abrupt Knu c kleboom Loader actions
such as drop and catch . This tends to produce
instability. U se extreme care when swinging the
boom forward to prevent damage to the truc k When
loading, position Knuc kleboom Loader as close to
stoc k pile as possible to assure m aximum
loading without ch angin g position.
