DANGER

The aerial platform is not electrically insulated. Death or serious injury can result from contact with,or inadequate clearance from,an energized conductor.

Do not go closer than the minimum safe approach distance as defined by the Mini mum Safe Approach Distance section in Chapter 3–Safety.

Regard all conductors as energized. Allow for electrical wire sag and aerial platform sway. If the platform, booms, or any part of the aerial platform contacts a high-voltage electrical

conductor, the entire machine can become electrically charged. Ifthathappens,remain onthe machineand donot contactanyotherstructure orobject.This

includestheground, adjacentbuildings,poles,andany otherobjectsthat are notpartofthe aerial platform.

Such contact could make your body a conductor to the other object, creating an electrical shock hazard resulting in death or serious injury.

If an aerial platform is in contact with an energized conductor the platform operator must warn groundpersonnelinthevicinityto stay away.Theirbodies can conduct electricity creating an electrical shock hazard resulting in death or serious injury.

Do not approach or leave the aerial platform until the electricity has been turned off. Donot attempttooperatethe lowercontrolswhentheplatform,booms,oranypartof theae

rial platform isincontactwitha high-voltage electrical conductor or ifthereisanimmediate danger of such contact.

Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizingthat deathor seriousinjurycanresultfromcontactwithanenergizedconductor.

Battery posts, terminals and related accessories contain lead and lead components, chemicals knownto the State of California to cause cancer and birthdefects or other reproductive harm. Wash hands after handling.

Driving and Steering

DANGER

The aerialplatformcan tip over ifitbecomesunsta ble. Death or serious injury can result from a tip-over accident. Do not drive an elevated aerial platform on soft, uneven, or sloping surfaces. Do not drive a fully stowed machine on grades that exceed 25 percent.

A fully stowed machine may be operated on grades up to 25 percent. A grade of 25 percent is a 30″ (7.62 m) vertical rise in 10′ (3.05 m) horizontal length.

DANGER

Death or serious injury can result from improperly driving or steering the aerial platform.Read and un derstand the information in this manual and on the placards and decals on the machine before operat ing the aerial platform on the job.

The blue and yellow arrows on the chassis indicate the direction the chassis will move when the drive or steer control is moved toward the corresponding color.

When the machine is in the stowed position, with the booms centeredbetweenthe rear wheels, the direction of drive and steer control movement corresponds with the direction of chassis movement.

When the turntable is rotated from the stowed position, withthebooms toeither sideofor infrontofthechassis, the direction of control movement does not correspond with the direction of chassis movement.

To avoid confusion, always drive to the work area or movebetweenworkareaswiththeturntableandbooms in the stowed position. After arriving at the work area, the booms may be positioned to the side or the front of thechassis forfinalpositioning.Alwayslookin thedirec tion ofmovementas indicated by the directional arrows on the chassis.

Front

Use the following procedure to operate the drive and steer functions.

1. Determine the desired drive range for the specific driving conditions.

●

Use high range when traveling across firm, flat, levelsurfaces.High range can only be activated when the booms are stowed. High range is for high speed, low torque operation.

●

Use low range for dr iving on loading ramps or other steep grades and when safety considerations demand slow deliberate machine movement. Low range is for low speed, high torque operation.

2. Step down on the platform foot switch.

3. Pushthedrivejoystick forwardto move thechassis forward,the direction of the bluearrow.Pullthejoy stick backward to move the chassis backward, the directionof theyellowarrow.Thedr ivespeedis pro portional to the joystick position.

4. To stop drive motion, return the joystick to neutral.

5. Place the steer switch in the color-coded direction necessary toturnleftor right asindicatedby thear rows on the chassis.

Note The steering wheels are not self-centering. Set the steeringwheelsstraightaheadaftercompleting aturn.

6. Afterdriving tothedesiredlocation,releasethefoot switch,orpushthe emergency stop button toapply the parking brakes.

Drive Speeds

The drive speed is proportional to the joystick position. The farther the joystick is moved, the faster the travel speed.

Always slow down and shift the drive system to low range before traveling overrough terrain or any sloped surface.

TB37 – 0172094 page 8 - 3

Page 41

Chapter 8. Operation

Drive speed ranges are interlocked through a limit switch that senses the main boom position. When the boomiselevated,onlythe slowestdr ive speedwillwork regardlessofthedriverange switchposition.Toavoid a sudden speed change from high to low elevated boom speed, always bring the machine to a stop before rais ing the booms from the stowed position.

DANGER

Thepotentialfor anaccidentincreases whensafety devices do not function properly. Death or serious injury can result from such accidents. Do not alter, disable, or override any safety device.
