MINIMIZE ACCELERATION DURING PIVOTING MOVEMENT.

• To drive straight forward or reverse, move the control-
lers for both tracks at the same time, direction and posi-
tion.
• Always fully widen the track prior to driving, if possible,
for easier steering and increased stability.

path is firm, level and uniform.
