Snorkel S2545 - Manual (Page 41)

The rails are free to move when the foot is
completely off its rest. Uncontrolled movement
of the rails can cause personal injury. Do not
move the foot more than a quarter inch (6 mm)
to offset the detent pin and the hole.
2. Pull one of the detent pins down and pull
back on the guardrail about 1
4
″ (6 mm) or just
enough to offset the pin from the hole.
Repeat this step for the detent pin on the
other side of the entrance.
3. Stand facing the rear of the platform, grasp
the top rail and pull backward.
4. Lower the guardrails to the platform floor.
Use the following procedure to raise the extension
and main platform rails.
1. Carefully lift upward on the rails.
2. Push the rails forward firmly to automatically
seat the detent pins into their holes.
3. Check the detent pins to make sure they are
properly seated.
4. Install the snapper pins with the head to the
outside of the platform.
■ 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 pin protrudes through an
opening in the brake disc to prevent movement
(refer to Figure 9.7). A flow control valve slows
the pin movement to allow the aerial platform to
stop before the parking brakes engage.
Figure 9.7—Mechanical Brake
This system operates automatically to stop and
hold the aerial platform when the drive controls
are released or power is interrupted. Manually
disengage the brakes before towing or winching
the aerial platform as described under Towing in
Chapter 11—Emergency Operation.
■ Swing-Out Trays
Batteries and hydraulic components are enclosed
in swing-out trays (refer to Figure 9.8) on each
side of the chassis.
Figure 9.8—Swing-Out Tray
The tray on the right side of the chassis contains
the electrical panel for the lower controls, the
hydraulic directional control valve, the
free-wheeling valve, reservoir, pump, and the
hydraulic fluid filter. The tray on the left side
contains the four batteries and the charger.
The aerial platform can tip over if it becomes
unstable. Death or serious injury can result
from a tip-over accident. Do not open the
swing-out trays when the platform is raised
more than nine feet.
To open a tray, pull up on the latch, step down on
the pothole protector skid, and swing the tray
open.
If the platform is raised to approximately 24
″ and
the pothole protection skids are down, the trays will
swing out without lowering the skids.
