The truck shall back out of the stack aisle into the main aisle,
making the 90-degree right-hand turn in one motion without going
forward, and proceed forward along the main aisle in the portion
of the course marked "C" until it reaches the third pallet area.
f. The truck shall make a 90-degree right-hand turn in one motion
without backing and pick up rated load which has been placed in
the location marked "Z". The truck shall back out into the main
aisle, making the 90-degree right-hand turn in one motion, and
proceed further along the main aisle in the portion of the course
marked `D until it reaches the portion of the course marked "E",
containing the obstacle blocks.
g. The obstacle blocks shall be traversed by the truck being driven
through this area in a straight line so that its left wheels pass
over the first block and the right wheels pass over the second
block . This part of the test may be conducted at low speed with
the transmission in low range. However, the truck shall not be
stopped prior to or while going over the blocks.
h. The truck shall proceed further along the main aisle in the
portions of the course marked "F" and "G" until it reaches the
position on the ramp labeled "Stopping Point". The driver shall
stop the truck and then resume ascending the ramp. After the top
of the ramp is reached, proceed along the main aisle in the
portion of the course marked "J", "K", and "L".
i. When the truck reaches the portion of the course marked "M", the
operator shall stop. On every other lap, the operator shall turn
off the ignition and restart the engine. On alternate laps the
operator shall engage the starter switch without turning off the
engine. After completion of this portion of the test, proceed
along the main aisle and start the next cycle. All stops shall be
at the maximum safe deceleration rate. The operator shall actuate
and release the parking brake at least once during each circuit.
j. The truck shall then reenter the portion of the course marked "A".
In portions "A", "B", "C", and "1)", the procedure shall be the
same as described in preceding paragraphs, except that the truck
shall place a test load at each point where it was previously
indicated that the truck picked one up, and pick up a load where
it was previously indicated one was placed. Maneuvers in the
balance of the course beyond the portion marked "D" shall be the
same as described in preceding paragraphs.
k. One-half of the total number of laps shall be traversed in the
opposite direction with all operations reversed accordingly. This
may be accomplished after completion of each 8-hour operating day
or multiple thereof. That is, 50 percent of the laps shall be
accomplished in the clockwise direction and 50 percent in the
counterclockwise direction or vice versa. The test course need
not be rearranged for the reverse travel.
