Load Capacity and the Lift Light
A lifter’s Load Capacity is rated at a vacuum level of 16" Hg [-54 kPa] (see SPECIFICATIONS).
After the lifter has attained this level, the vacuum pumps turn off automatically, to conserve
battery energy. At the same time, the green vacuum lift light turns on, to indicate that the lifter
is ready to lift the maximum load weight.
WARNING: Never attempt to lift load unless green lift light is illuminated.
Do not attempt to lift the load unless the lift light is illuminated; such an attempt could result in a
load release and possible injury to the operator.
Monitoring Vacuum Indicators
The low vacuum warning light and the vacuum gauge must remain completely visible to the
operator, so that they can be monitored throughout the entire lift.
WARNING: Vacuum indicators must be visible to operator throughout entire lift.
If the vacuum system experiences leakage while the lifter is attached to the load, the vacuum
pumps turn
on automatically, as required to maintain sufficient vacuum for lifting the maximum
load weight. The lift light turns
off while the pumps are running, to signal the reduction in
vacuum to the operator.
If the pumps turn on and the lift light turns off while you are lifting a load, make sure the
vacuum gauge shows a vacuum level of 16" Hg [-54 kPa] or higher. If not, move away and stay
clear of the load until it can be lowered to the ground or a stable support.
WARNING: Stay clear of any suspended load while vacuum level is lower than
16" Hg [-54 kPa].
Discontinue lifter use until the cause of the vacuum loss can be determined. If the pump runs at
intervals of ten minutes or less while the lifter is attached to clean, smooth, nonporous materials,
the leakage is likely to be in the vacuum system. In this event, perform the V
ACUUM
T
EST
(see
MAINTENANCE) and inspect the vacuum pads for damage (see MAINTENANCE: V
ACUUM
P
AD
M
AINTENANCE
: Inspection). If the vacuum loss cannot be remedied immediately, perform
inspection and maintenance as needed to identify and correct any deficiency before resuming
normal operation of the lifter.
Low Vacuum Warning Buzzer
Using the low vacuum warning buzzer requires minimal interaction from the operator. The
warning buzzer sounds an alarm until the lifter attains sufficient vacuum to lift the maximum load
weight (see SPECIFICATIONS: Load Capacity). After the lifter has attained this vacuum level, the
alarm stops sounding, to indicate that the lifter is ready to lift the load.
WARNING: Never attempt to lift load while alarm is sounding.
Do not attempt to lift the load while the alarm is sounding; such an attempt could result in a load
release and possible injury to the operator.
If the vacuum system experiences leakage while the lifter is attached to the load, the vacuum
pump turns on automatically, as required to maintain sufficient vacuum. The alarm also sounds
while the pump is running, to signal the reduction in vacuum to the operator. If the alarm
sounds while you are lifting a load, make sure the vacuum gauge shows a vacuum level of 16"
Hg [-54 kPa] or higher. If not, immediately move away and stay clear of the load until it can be
lowered to the ground or a stable support.
