Park Brake Adjustment
When park brake is in the engaged position the
distance between the trunion and the bolt head
at the rear of the assembly should measure 1/8”
to 1/4” and the spring should measure 1.25”. To
adjust the gap between the trunion and the bolt
head loosen the nut against the yoke then turn
the bolt head the proper direction to achieve the
proper gap. To adjust the length of the spring
turn the nut against the spring the proper direc-
tion to lengthen or shorten the spring. This
adjustment is the same for both sides. FIG - 8
• If brake lever trys to catch as you engage the
brake the spring needs to be tightened. When
you change the spring length you also have to
maintain the 1/8” to 1/4” gap between the bolt
head and the trunion.
NOTE: Do not force the brake lever into the on
position if it is catching this will cause damage
to the brake assembly.
• If brake squeaks while the machine is in use.
The spring may be to tight or the gap between
the bolt head and the trunion may be to large.

By moving the levers an equal amount forward
or back the machine will move in a straight line
in that direction. FIG - 11
Movement of either lever forward will cause the
right or left wheel to rotate in a forward direc-
tion. To stop movement pull both levers into the
neutral position.
To turn right while moving in a forward direction
pull the right lever back towards the neutral
position, this will slow the rotation of the right
wheel and cause the machine to turn in that
direction.
To turn left while moving in a forward direction
pull the left lever back towards the neutral
position, this will slow the rotation of the left
wheel and cause the machine to turn in that
direction.
To zero turn pull one lever back beyond neutral
while holding the other slightly ahead of neu-
tral. NOTE: The direction of the zero turn will
be determined by which lever is pulled back
beyond neutral. Thus left lever back, left zero
turn and opposite for right zero turn. Use extra
care when using this maneuver the machine
can spin very rapidly if one lever is posi-
tioned to far ahead of the other.
