Lanyard Anchors

There are two lanyard anchors at the left front of the
platform (refer to Figure 8.12).
To inspect the lanyard anchors:
1. Visually inspect the lanyard anchors to make sure
they are in place and are not deformed.
2. Look for visible cracks in the welds and at the weld
to parent material joints. A bright light may be used
to provide adequate visibility of the inspection area.

Use the following procedure to operate the machine from
the upper controls:
1. Make sure the battery disconnect is plugged in.
2. At the lower controls, twist the emergency stop button
clockwise and turn the start switch on.

Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
4. Press either the drive or platform select button and
test the interlock by moving the joystick without en-
gaging the interlock switch. If movement occurs the
interlock is not functioning properly. Do not operate
the machine until the problem is corrected.
5. Test the operation of each control in both directions
from the upper controls.
• Press the drive select button and test the operation
of the joystick in both directions. The joystick should
only operate the drive functions.

tion of the joystick in both directions. The joystick
should only operate the platform functions.
6. The maximum travel speed is interlocked through a
limit switch at the front of the chassis that senses the
position of the platform.
• When the platform is raised approximately 1' (0.3
m), the machine should travel in low speed only.
• To operate in high speed the platform must be fully
lowered in the stowed position.

Emergency Stop

To test the emergency stop button from the upper
controls:
1. At the lower controls, twist the emergency stop button
clockwise and place the control selector switch in the
upper control position.
2. At the upper controls, push the emergency stop but-
ton inward to turn off electrical power.
3. Verify that the upper control platform and drive func-
tions do not operate.
Horn Button
The machine may be equipped with an optional horn.
Operate the horn button (refer to Figure 8.15) to ensure
that it sounds to warn personnel in the area.

Placards and Decals

To inspect the placards and decals:
1. Inspect all safety and operational placards and de-
cals. Make certain they are in place, in good condi-
tion, and are legible.
2. Clean the placards and decals with soap and water,
and a soft cloth if the words or pictures cannot be
seen.
Caution
Solvents may contain hazardous ingredients. Follow
the manufacturer's label for proper use and disposal.
Wear protective gloves and splash-proof safety
glasses when using solvents.
3. Remove wet paint overspray using a natural biode-
gradable solvent and a soft cloth.
4. Replace any missing or illegible placards or decals
before operating the aerial platform.
Placard and decal kits are available from Snorkel.
The safety related placards and decals are illustrated on
