4.2 STAIRS/GROUND TRANSFER/LOADING/UNLOADING SELECTION SWITCHES
“STAIR” mode
In case that the “Stairs” mode is selected, the Travelling
Wheels (front wheels) will be off the floor and the Floor will
be slightly tilted, making the machine ready for going
up/down the stairs. During ascent or descent, the tilt angle
of the Floor is automatically adjusted in accordance with the
stair angle to keep it within a safe range.
“GROUND” mode
In case that the operator presses the Travelling Switch after
selecting the “GROUND” mode, the Travelling Wheels (front wheels) touch the floor, enabling the machine to travel
on flat ground with the assistance of an operator.
“TRANSFER” mode
In case that the “TRANSFER” mode is selected on flat surface, the floor will be lowered, making the machine ready
for loading/unloading the wheelchair.

“STRAIGHT” mode
The RAIL FRAME Switch is NOT used under
normal conditions. This switch is ONLY used when
the rail is bent unexpectedly while travelling on the
stairs. In such case, selecting the “STRAIGHT”
position causes the rail to extend, enabling the
machine to move smoothly on the stairs.
“BENT” mode
The RAIL FRAME Switch is NOT used under normal conditions. Usually, the rail is bent automatically before the machi-
ne reaches the landing in ascent, or before the machine enters the stairs in descent; once the rail is bent, the “BENT”
green lamp illuminates to indicate that the bending has been completed. However, the switch is ONLY used when
ascending/descending the following:
• Stairs with five steps or less;
• Open stairs; or
• Stairs made of aluminum, etc.
4. DESCRIPTION OF PARTS
4.1 KEY SWITCH
The Key Switch on the operation panel turns the
power on and off.
Turning the Key Switch clockwise turns the power on,
and turning it counterclockwise turns the power off.

4.6 BATTERY GAUGE INDICATION
• When Key Switch is set to ON, Battery Gauge indication may differ from its
previous indication when the power was last turned on.
• The Battery Pack can be recharged when the Battery Gauge indication has
decreased even if only slightly. Charging at frequent intervals will extend the
battery life.
CAUTION
• Do not turn the Key Switch on when the battery is being charged.
• Doing so causes the Battery Gauge to indicate the Battery Pack is fully
charged even when the charging process has not yet been completed.
This results in shorter operating time.
• To confirm a fully charged Battery Pack, be sure to check it via the
Charger’s full charge indication.
• Battery Gauge indication may not accurately correspond to the actual
remaining operating time regarding battery capacity depending on the
usage conditions, usage environment, and the degree of deterioration of
the battery.
• When the Key Switch is turned on, the Battery Gauge indication may
differ from its previous indication when the power was last turned off.
CAUTION
