Snorkel X33BE-sn10131+V-1 - Manual (Page 21)

The DRIVE (forward) and the platform-lowering
alarms beep at one beep per second. DRIVE (re-
verse) beeps at two beeps per second. The level
sensor alarm is a high-low warbling sound.
❑ Lowering
The lowering alarm warns people near an RT that
the platform is coming down and the scissor arm
assembly is closing.
❑ High temperature
The high-temperature alarm warns you that the en-
gine is overheating. When the alarm sounds you
should immediately lower the platform completely
down then turn the engine off until the condition
that caused the overheating has been corrected.
(See Automatic Shut-Offs & Circuit Breakers chap-
ter 5 for more information.)
❑ Low oil pressure
The low pressure alarm warns you that the engine
oil pressure is near the lower limit for safe operation
of the engine. When the alarm sounds you should
immediately lower the platform completely down
then turn the engine off until the condition that
caused the low oil pressure has been corrected.
(See Automatic Shut-Offs & Circuit Breakers chap-
ter 5 for more information.)
❑ Drive (reverse)
The DRIVE (reverse) alarm alerts people that the
RT is traveling backward along the ground. This
a larm beeps twice as fast as the DRIVE (forward)
❑ Drive (forward)
The DRIVE (forward) alarm alerts people that the
RT is traveling forward along the ground. This
alarm beeps half as fast as the DRIVE (reverse)
alarm.
■ Guardrails
Figure 2.4 - Guardrails
The guardrails help protect you from falling off the
platform. Be sure the guardrails are properly in-
stalled and that the gate is in place.

2. Safety Devices
The LOAD SENSING alarm also emits a high-low
warbling sound, as does the alarm that sounds
when the scissor stack stops descending at 1
metre from stowed position
❑ Load sensing system
The load sensing system sounds an alarm and
illuminates a lamp to warn the operator that the
platform is overloaded.
The alarm will sound and the overload light
(see
figure 2. 3) will illuminate as soon as the overload
point is reached.
Figure 2.3 - Platform Overload Light
NOTE:
When the alarm sounds all platform movement
[drive forward / reverse and lift up / down is
prevented.
The alarm and function interlock will be active
until the load is reduced.

When the plat form is ap proximately 1 metre from
the stowed po sition the plat form will stop low ering
and a warn ing alarm will sound. This alarm will con -
tinue to sound un til the joy stick is re leased and the
preset time pe riod has elapsed.
NOTE 1:
This is intended to prompt, and allow time for the
operator to check that no person has any
appendage in the scissor arm mechanism.
NOTE 2:
The joystick must be released and then reapplied
once the preset time period has elapsed before
the platform will continue to descend.
