After the battery is fully charged (in approx 16 hours), the charger turns off automatically and
the blue light on the battery gauge turns on. Replace the battery whenever the operating time
between recharging is no longer satisfactory (see REPLACEMENT PARTS LIST).

Each power loss warning buzzer is powered by an independent battery, which can be tested
while the lifter is not running or attached to a load: Press the battery test switch on the
corresponding pad channel as shown and listen for the alarm. If the alarm does not sound, the
battery must be replaced. Press the power loss warning battery holder inward, causing it to
release, and slide the battery tray out as shown. Install a new 9-volt battery according to the
polarity markings and retest the warning buzzer.

Pad to Load Friction Coefficient
The friction coefficient represents the lifter's ability to resist load slippage (Note: Flat
lifters are exempt). The Maximum Load Capacity assumes a friction coefficient of 1.0 (see
SPECIFICATIONS). This rating is based on testing of clean, new, standard rubber vacuum pads
on clean, dry, regular glass. If the lifter is used under other conditions, a qualified person must
first determine the effective lifting capacity.
Exposure to heat, UV light or chemicals can cause vacuum pads to deteriorate. Standard rubber
pads should be replaced on a regular basis (at least every 2 years), to prevent deterioration of
the friction coefficient.
Pad Inspection
Inspect each vacuum pad for the following deficiencies routinely
(see preceding I
NSPECTION
and T
ESTING
S
CHEDULES
), and correct
them before using the lifter.
• Contaminates on the pad face (1) or sealing edges (2) (see Pad
Cleaning discussion to follow).
• Filter screen (3) missing from pad face (see REPLACEMENT
PARTS LIST).
• Nicks, cuts or abrasions in sealing edges of vacuum pad (see
REPLACEMENT PARTS LIST). 3 2
