Platform; Raising And Lowering; Brakes; Swing-Out/Slide-Out Trays - Snorkel TM12 Series Operator's Manual

Note
Holding the steer switch down too long may result in
a sharp turn. This is especially true when driving and
steering at the same time. It may be easier to turn the
wheels in small increments using a series of quick taps
on the steer switch.
2. Set the steer wheels straight ahead after completing
a turn. The steering wheels are not self-centering.

Platform

Use care when entering and exiting the platform to avoid
slipping and/or falling. Securely close the safety chain
when the platform is occupied.

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. Press the platform select button (refer to Figure 9.2).
2. Squeeze and hold the interlock switch against the
joystick.
• To raise the platform, slowly pull the joystick back
until the desired speed is reached.
• To lower the platform, push the joystick forward.

Brakes

Each rear wheel is equipped with a mechanical spring-
applied, hydraulically released parking brake. When
the drive control is in neutral, a spring-activated brake
actuator presses the park brake shoe (refer to Figure 9.3)
against the wheel to prevent movement.
Parking Brake
Figure 9.3 – Rear of Chassis
This system operates automatically to stop and hold
the aerial platform when the drive control is released or
power is interrupted.
