3-12 ADJUSTING ADJUSTMENT ARMS
There are two sets of adjustment arms con-
necting the upper deck to the lower deck. Each
arm must be unlocked as it is adjusted and locked
when it is in position. (See Section 3-9) for opera-
tion of hydraulic and air lock controls).
3-12.1 Hold the LOCK CONTROL in the un-
lock position (See Figure 3-2) and joggle the
TRAILER TILT CONTROL for that arm until
it unlocks.
3-12.2 Continue to hold the LOCK CONTROL
in the unlock position as the arm is raised or
lowered.
3-12.3 When the arm reaches the desired po-
sition, release the LOCK CONTROL and
joggle the TRAILER TILT CONTROL until
the arm is locked in position.
3-12.4 Verify that the arm is locked by looking
through the window on the arm to see if the
cogs are engaged (See Figure 3-5) .
WARNING
DO NOT PUT FINGERS OR OBJECTS
INTO THE LOCK WINDOW. VISUALLY
CHECK THE LOCK ONLY. USE HY-
DRAULIC CONTROLS TO ENGAGE
COGS.
3-12.5 If the lock is not correctly engaged, jog-
gle the TRAILER TILT CONTROL until the
cogs engage.
3-12.6 The adjusting arms are controlled by slave
cylinders that can get out of time, allowing one
side to be higher than the other side. When one
side is more than 1/4" higher than the other
side, the cylinders must be re-timed. Extend the
cylinders all the way out then continue to hold
the valve open for 5 to 10 seconds, which forces
cylinder pistons to the same extended position.
