DESCENDING STAIRS
1. Press ascend/descend button briefly again until
indicator light flashes green. Unit is now in descend
mode. Support wheels will move to descend position
automatically. Round-up switch is now inactive.
2. With support wheels in descend position, powered
stair climber can be rolled over step and support
wheels will lower unit onto next step down.
3. When main wheels land on lower step, support
wheels automatically rotate to descend position for
descent onto next step, all within approximately half
a second.
CAUTION! As soon as powered stair climber rolls
off step, ensure main wheels are kept against
the rise until support wheels reach descend
position.
• During descent, indicator light changes to constant
red. After reaching descend position, indicator light
changes back to flashing green.
• Just before swing arm reaches descend position,
support wheels reach upper edge of stair and lift
unit approximately half an inch.
• For closed risers with low steps, support wheels may
touch stair riser and unit could move approximately
3-4" forward. This is normal as unit prepares to
advance to next step.
• It is unnecessary to press round-up switch
to descend stairs. Support wheels operate
automatically at a set speed.
IMPORTANT OPERATOR INFORMATION
• When ascending, load balance changes as soon
as support wheels start lifting load.
• Care should be taken
at the point where
support wheels take
load during ascent.
A forward
movement of unit
can be stopped
by tilting handle
backward.
(See Figure 9)
• To eliminate any
major forward
movements, lower
unit backward
about 15° before support wheels begin to lift.

OPERATION CONTINUED
Figure 9
• Do not overload unit. Exceeding load capacity
activates overload mode, causing it to stop and
lower main wheels slowly to lower step. Indicator
light flashes red for about three seconds after which
ascend/descend button will need to be reset.
CAUTION! Once battery is discharged, unit
goes into overload even with loads below
specified capacity.
• Never throw loads onto unit. Impact could result in
fracturing drive unit. If necessary, to load unit in a
horizontal position, ensure support wheels are raised
between main wheels and carefully place item on
unit. (See Figures 10-11)

Loading
• During normal operation, locking hooks securely
hold battery. A strong, vertical pull is required to
remove it. Moving backward very quickly and
striking a high step or similar equipment abuse
could result in battery ejecting from its location.
Powered stair climber will cease operation. Failure
to negotiate steps "square-on" will damage
underside of drive unit. (See Figure 12)
