Chapter 9 – Operation

34 S2646/S3246 – 0410063EE

Figure 9.2 – Upper Controls

Note

The upper controls will not operate while the control se-

lector is in the lower position.

2. Enter the platform and lower the gravity gate. Make

certain the entry gate is securely pinned in place.

3. Pull the emergency stop button out.

4. The aerial platform may be driven and the platform

may be raised and lowered from the upper controls.

Driving

ADanger

The aerial platform can tip over if it becomes un-

stable. Death or serious injury will result from a tip-

over accident. Do not drive an elevated aerial plat-

form 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 0.76 m (30″) verti-

cal rise in 3.05 m (10′) horizontal length.

AWarning

Death or serious injury can result from improperly

driving or steering the aerial platform. Read and

understand the information in this manual and on

the placards and decals on the machine before op-

erating the aerial platform on the job.

Use the following procedure to operate the drive func-

tions.

1. Place the drive/lift selector switch (refer to Figure 9.2)

in the drive position.

2. Squeeze and hold the interlock switch against the

joystick.

• To move forward, slowly push the joystick forward.

• To move backward, slowly pull the joystick back-

ward.

Drive Range Switch

The drive range switch has two positions to select drive

wheel operation:

• High (Rabbit) – for normal driving conditions.

• Low (Turtle) – for driving on grades up to 25 percent

that require low speed and high torque operation,

where high range is not sufficient to climb the grade.

In high the machine will travel up to 3.2 km/h (2 mph)

when the platform is raised less than 2.4 m (8′) and up to

0.8 km/h (0.5 mph) when the platform is raised above 2.4 m

(8′). Place the drive range switch in high for normal ma-

chine operation.

Place the drive range switch in low, with the platform fully

lowered and the extension deck securely pinned, before

driving up a ramp to load the machine for transport.

ACaution

The extension deck is free to move when the pins

are disengaged. Make certain the pin is engaged

when the deck is extended in the working position

and when it is stowed.

Drive Speeds

The drive speed is proportional to the joystick position.

The farther the joystick is moved, the faster the travel

speed.

Drive speed ranges are interlocked through a limit switch

that senses scissors arm position. When the platform is

elevated below approximately 2.1 to 2.4 m (7 to 8 feet),

the aerial platform may be driven within the full range of

drive speeds. Above 2.1 to 2.4 m (7 to 8 feet) of elevation,

drive speed is limited to 0.8 km/h (0.5 mph).

AWarning

The potential for an accident increases when safety

devices do not function properly. Death or serious

injury can result from such accidents. Do not alter,

disable, or override any safety device.

Do not use the aerial platform if it drives faster than 0.8

km/h (0.5 mph), which is 6.7 m (22′) in 30 seconds, when

elevated above 2.4 m (8′).
