For ECS Handles: To lock the drive levers in "neutral lock", squeeze the drive
levers to the "neutral" position. See Figure 17 (b). Place thumbs on the inner
thumb lobe of the neutral lock /park brake latches and rotate them to the "neutral"
position. See Figure 17 (c). Release the drive levers.
To lock the drive levers in "park brake", squeeze the drive levers farther to the
"brake" position. Place thumbs on the inner thumb lobe of the neutral lock/park
brake latches and rotate them to the "park" position. See Figure 17 (d). Release
drive levers.
POTENTIAL HAZARD
If the neutral lock/park brake latches are not completely
engaged the drive levers could unexpectedly slip into the
forward drive position.
WHAT CAN HAPPEN
If the drive levers slip into the drive position, the unit could lurch
forward and cause injury or property damage.
HOW TO AVOID THE HAZARD
Be sure the drive levers are securely seated at the bottom of the
"neutral" or "park" areas of the neutral lock latches.
To place the drive levers in the "drive" position, slightly squeeze the drive levers
while placing thumbs on the outer thumb lobe of the neutral lock/park brake
latches (or the index finger on the front lobe) and rotate them from under the drive
levers. Slowly and carefully release the drive levers. See Figure 17 (a).
