TO LIFT AND MOVE THE LOAD

Positioning the Lift Bar

WARNING: Lift bar must be oriented vertically to lift

load.

Never lift the load from a flat position with the lift bar latched parallel to

the load. Always disengage the tilt latch (see TO TILT THE LOAD to

follow) and raise the lift bar to a vertical orientation before attempting to lift.

Load Capacity and the Warning 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 pump turns off automatically, to conserve

battery energy. At the same time, the low vacuum warning light turns off, to indicate that the

lifter is ready to lift the maximum load weight.

WARNING: Never attempt to lift load while red warning light is illuminated.

Do not attempt to lift the load while the warning 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

pump turns on automatically, as required to maintain sufficient vacuum for lifting the maximum

load weight. The low vacuum warning light also turns on and remains illuminated while the

pump is running, to signal the reduction in vacuum to the operator.

If the pump and warning light turn on 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 VACUUM

TEST (see MAINTENANCE) and inspect the vacuum pads for damage (see MAINTENANCE: VACUUM

PAD MAINTENANCE: 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.
