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

•Release both hydraulic relief levers.

•From the rear push on the frame and try to move the Z-Series.

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.
