Service Brake
See page 49 for brake schematic.
Inspect the Service Brake DAILY. A daily Service Brake inspection performed with an empty buggy
traveling at full speed must demonstrate that when full foot pressure (125 LB.) is applied to the brake
pedal both brakes engage equally, the pedal is level with the top of the operator’s platform, the buggy
stops in 6-8’ of travel and the engine stalls.

time by running buggy, applying
brake and having an observer verify
both brakes lock up together.

that engages late in increments of
¼ turn until both brakes activate
together. Verify brake operation with
an observer (see 1 above).
