1. Place the machine on a firm, level surface.
2. Use an inclinometer to ensure that the chassis is level from front to rear and side to side.
3. Deploy the maintenance brace (see “Blocking The Elevating Assembly” on page 2-8).
4. Disconnect the switch leads and connect a multimeter to the switch.
• The switch contacts should be OPEN (no continuity).
• Push the lever down to close the switch contacts. If there is no continuity, the switch is defective.
5. Connect the switch leads, store the maintenance brace and lower the work platform.
6. Elevate the work platform not more than 1 m (3 ft.).
7. With the Platform/Chassis switch on CHASSIS, push the Tilt Sensor base to test the alarm circuit.
• If the alarm does not sound, the switch is out of adjustment.
8. Turn the Drive Speed Switch to HI SPEED and attempt to drive the machine.
• If the machine will drive faster than 0,8 km/h (0.5 mph), the switch is out of adjustment.
9. Lower the work platform completely.
