Raising And Lowering; Lowering Interrupt; Overload Protection; Extending - Snorkel S3219E Operator's Manual

Be sure the fold down guardrails are up and the hardware
is securely tightened, anytime the machine is not being
transported.

Raising and Lowering

The raise speed is proportional to the joystick position.
The farther the joystick is moved, the faster the platform
raises. There is only one lowering speed.
1. Place the drive/lift selector switch (refer to Figure 3)
in the lift position.
2. Squeeze and hold the interlock switch against the
joystick.
To raise the platform, slowly pull the joystick
backward, until the desired height is reached.
To lower the platform, push the joystick forward.

Lowering Interrupt

When the platform is lowered to about 1.8 m (6 ) lowering
stops. The platform will not lower for five seconds regard-
less of the joystick position.
Center the control in neutral to reset the lowering function,
then continue to lower the platform.
When the platform is below 1.8 m (6 ) and the control is
moved to lower the platform, there is a 1.5 second delay
before movement begins.

Overload Protection

When the load in the platform is near or at rated capac-
ity, an alarm will sound and the red light on the upper
controls will flash.
The alarm and light warn the operator that the platform
is close to becoming overloaded. All functions remain
fully operational.
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not exceed the capacity values indicated
on the platform rating placard.
If the platform is fully lowered and is overloaded, when
it is elevated just past 1.8 m (6 ), a control module will
stop the lift and drive functions and the alarm will sound
and the warning light will flash. The platform can still be
lowered to remove the excess load.
If the platform is elevated just past 1.8 m (6 ) and material
is added to the platform overloading it, a control module
will stop the lift, drive and lower functions and the alarm
will sound and the warning light will flash. In this case,
remove the load in excess of rated capacity and cycle
the emergency stop button at the upper controls to return
to normal operation.

Danger

Extending

The platform can be extended and securely locked into
position.
Use the following procedure to extend the platform:
1. Enter the platform and close the gate.
Caution
The extension deck is free to move when the exten-
sion handle locks are disengaged. Personal injury may
result from accidentally extending or retracting the
deck. Make certain both extension handle locks are
fully engaged when the deck is extended in the work-
ing position and when it is stowed. Do not attempt to
extend or retract the platform unless the aerial platform
is on a level surface.
2. While facing the front of the platform, grasp the
platform extension handles, raise them and push
the extension deck forward to extend the deck. Fully
lower the handles at the mid or front position and
ensure they are locked in their lowered position.
3. Try to move the rails back and forth to make sure the
platform extension deck is locked in position.
Use the following procedure to retract the platform:
1. Enter the platform and close the gate.

Driving and Steering

Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive on
grades that exceed 25 percent.
