Emergency Lowering Valves
In the event of a power failure, the emergency lowering
valve on the ram can be used to lower the booms.
This process involves assistance from the ground.
• Operate the lower ram valve first because it is clos -
er to the ground
• Press on the lowering valve button to initiate lower-
ing and faciliate access to the top ram valve.
Note
Each emergency ram valve will automatically close
when the button is released.

Danger
If the emergency lower is used due to a machine
defect, do not use the machine. Contact your local
Snorkel representative.
Warning
If the emergency lower is used, the top and bottom
booms must be fully extended then fully lowered
before work can continue.

Figure 4.3 – Outrigger Location & Bubble Indicator
When the outriggers are securely under load, the LED
lights on the ground control station begin to illuminate
showing a green colour as shown in Figure 4.4.

Load/Not Under Load
The bubble indicator as shown in Figure 4.3 must be
used always to ensure the aerial platform is level on
the ground and safe to use.
Danger
The aerial platform can tip over if it becomes unsta -
ble. Death or serious injury will result from a tip-over
accident. Do not drive or position the aerial platform
for elevated use within 4 ′ (1.2 m) of any drop-off, hole,
or other tip-over hazard.
Emergency Slew
The emergency lowering lever may be used to lower
the platform if there is a malfunction in the hydraulic or
electrical system.
In the event of a failure, the machine can be manually
slewed by moving the slew platform clockwise or anti-
clockwise by inserting the slew lever into the insert and
rotating the gearbox (refer to Figure 4.5).
The slew lever for the aerial platform is located on the
side of the chassis as shown in Figure 4.5.
