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.

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

long cotter pins.

engages late.
Turn nut (16) clockwise on brake that
engages late in increments of ¼ turn until
both brakes activate together. Verify brake
operation with an observer (see 1 above).

tion away from brake bands.
