Stop the engine, remove the key from the ignition,
and engage the parking brake.

Release the parking brake and try again to move
the Z-Series by pushing.

necessary).
Adjusting Brake Force
Place the Z-Series on level surface without the
brake engaged and place blocks behind the
wheels.
Turn the engine OFF and remove the key from the
ignition.
From underneath the Z-Series directly behind the
caster wheel pivot bar, locate the brake rods. There
is one on the right and one on the left.
See Figure 11.
The factory sets a 1/16 gap minimum between the
brake arm and frame of the Z-Series. More
adjustment may be necessary
If increased force is needed, then rotate brake rods
clockwise.
If decreased force is needed, then rotate brake rods
counterclockwise.
Repeat process on the other brake rod.
Check the operation of the brakes before operating.
If the adjustment does not help, see your dealer.
