3.3 BRAKING AND STEERING
OPERATION WITH SMART CASTER
TECHNOLOGY
3.3.1 Applying the Brakes
To apply the four wheel central braking
system with the pendant, press the pendant
Brake On / Off button; the LED above the
button then illuminates green (Figure 3.3-1),
and the blue caster pedals on all four corners
of the chair automatically lower to lock
(Figure 3.3-2), and all four caster wheels will
then be locked from swiveling and rotating.
Info: To prevent unintended movement, the
brakes engage automatically after the unit
has been stationary for 30 seconds.
To apply the four-wheel central braking
system manually, gently depress the blue
caster pedal at any of the four corners of the
chair until the pedal stops (Figure 3.3-2). The
remaining three pedals will then automatically
lower to lock (Figure 3.3-2), and all four caster
wheels will then be locked from swiveling and
rotating.
sNOTICE: DO NOT apply excessive force
to pedal when manually applying brakes.
3.3.2 Unlocking the Brakes
To unlock the brakes with the pendant, press
the pendant Brake On / Off button; the LED
above the button then goes out (Figure 3.3-3),
the blue caster pedals on all four corners of
the chair will then automatically rise to unlock
(Figure 3.3-4), and all four caster wheels will
then rotate and swivel freely.
To unlock the brakes manually, gently lift the
blue caster pedal at any of the four corners
of the chair until the pedal is in a horizontal
position (Figure 3.3-4); the remaining three
pedals will then automatically rise to unlock
and all four caster wheels will then rotate and
swivel freely.
WARNING: Ensure the brakes are locked
when the patient is not being transported.
sNOTICE: DO NOT apply excessive force
to pedal when manually unlocking brakes.

EPC500ST-INS-LAB-RevA21 14
3.3.3 Activating Advanced Steer Mode — Pendant
To activate Advanced Steer Mode with the pendant,
press the pendant Steer Mode On / Off button.
The LED above the button then illuminates
green (Figure 3.3-5), and the blue caster pedals
automatically rise (Figure 3.3-6) at the patient foot
end of the chair. All four caster brakes will unlock and
the chair will be ready for transport. Push the chair
forward or backward — both front casters will lock
into Steer-Lock position, which is ideal for pushing
the chair from the patient head end. The chair will
steer along a straight path, maneuver corners, and
change direction with minimal effort.
Info: The casters will lock into Steer-Lock position
when turned to 6 o’clock or 12 o’clock, with the
chair’s patient foot end being 12 o’clock.
Info: Depending upon how the casters are oriented
when they lock, they can lock into Steer-Lock
position while trailing (6 o’clock) or leading (12
o’clock). If the casters lock in opposite orientations,
steering may be more difcult.
Info: The pendant will only lock the foot end casters
into Steer-Lock position.
3.3.4 Activating Advanced Steer Mode – Manually
When pushing from the head end: Activate foot
end Advanced Steer Mode by lifting the blue pedal
upward on either head end caster until the pedal
stops (Figure 3.3-6). Both foot end pedals will then
rise to lock foot end casters into Steer-Lock position,
the head end pedals will return to neutral position
(Figure 3.3-4), and the LED above the pendant
Steer Mode On / Off button will illuminate green
(Figure 3.3-5).

LED above the button will go out (Figure 3.3-7) and
the blue caster pedals in Steer-Lock position will

Info: All four casters must be parallel to each
other in the 6 o’clock or 12 o’clock position to be
able to properly go into neutral position. Failure
to place casters in this orientation may cause the
Steer Mode On / Off button to not deactivate
Steer Mode.
3.3.6 Deactivating Advanced Steer Mode –
Manually
Depress the blue caster pedal down to the neutral
position (Figure 3.3-4) on either caster locked into
Steer-Lock position. All four casters will now rotate
and swivel freely. Depressing the blue pedal down
past neutral until it stops will apply all four caster
brakes (Figure 3.3-2), locking all four casters into
brake position.
Info: After thirty seconds of no movement, Advanced
Steer Mode automatically deactivates and all four
caster wheels lock into brake position.
WARNING: To prevent unintended movement,
activate or deactivate Advanced Steer Mode only
while the chair is stopped.
