PERATION
Using the Vacuum Loss Warning Buzzer does not supersede any safety practices required by the
lifter’s manufacturer. The operator must continue to respect all cautionary statements in the
lifter instructions, even after the Warning Buzzer is installed.
WARNING: Warning Buzzer does NOT supersede required safety practices.
Operate the vacuum lifter as directed in its operating instructions. The Warning Buzzer begins
monitoring the lifter’s vacuum level when the lifter attaches to a load. If the lifter fails to reach
or maintain sufficient vacuum to lift the maximum load weight (see lifter specifications), the
Warning Buzzer sounds an alarm. If the lifter subsequently attains this vacuum level, the alarm
stops sounding.
WARNING: Do not attempt to lift load if alarm is sounding.
If the alarm is sounding, do not attempt to lift the load; such an attempt could result in a load
release and possible injury to the operator.
If the alarm sounds while you are lifting a load, make sure the lifter's vacuum gauge shows the
minimum lifting level or higher, as defined in the lifter's operating instructions. If not,
immediately 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 alarm is sounding.
Discontinue lifter use until the cause of the vacuum loss can be determined. Using the lifter on
contaminated, rough or porous surfaces may result in a vacuum loss, due to leakage between
the vacuum pads and the load. Since the alarm may sound in such circumstances, consult the
lifter’s operating instructions to determine whether the lifter can be used to lift the load. If the
vacuum loss is due to any other cause, perform inspection and maintenance as needed to
identify and correct any deficiency before resuming normal operation of the lifter.
Note: Under normal circumstances, the alarm does
not sound while the lifter is being attached to
the load; however, the alarm does sound briefly while the load is being released in the regular
way. This sound is normal for a Warning Buzzer that is working correctly; it simply indicates the
loss of vacuum that occurs when the load is being released.
While the lifter is attached to a load, the battery indicator light automatically signals the condition
of the Warning Buzzer’s battery: A green light indicates that the battery is in good condition,
whereas a red light indicates that the battery needs to be replaced. If a red light is showing,
replace the battery as directed in B
