9.1) Periodic cleaning of the unit
Competence: O - Trained operator
Frequency: Quarterly
In the operations that require the mechanical
protections disassembly, turn off before the voltage
to the electric installation.
In order to assure a reliable operating, it is necessary
a constant and careful cleaning of the unit both inside
and outside
Work phases for the cleaning:
- Open the mechanical protections by unscrewing the
xing screws.
- Turn off the voltage to the feeder removing the power
grid cable.
- Remove dust, dirt and greasiness marks.
- At the end of the operations, reconnect the general
connector and reassemble the protections.
Battery recharger:
When the battery charger reaches the yellow led (Fig.
27/a) the machine can be utilized because the battery
has reached the 3/4 of its charge.
Every 7 or 8 partial charges it’s good thing, in order
to save the battery, to carry out the complete battery
charge until the green led is reached (Fig. 27/b) (after
about 11 hours of charge).
It’s not possible to handle the machine while
the charging of the battery.

12) SHORT INSTRUCTIONS TO CORRECTLY CAR-
RY OUT THE RISE AND DESCENT OPERATIONS
WITH THE MOBILE TRACK STAIR CLIMBER
12.1) Descent
1st phase: Once the wheelchair is properly hooked (the
green lighted must be lighted up on the panel), by a soft
pressure downwards (Fig. 28/b), on the steering bar,
make the nose of the machine rise (Fig. 28/d), activating
the auxiliary wheels (Fig. 28/c). In that way it’s possible,
without any effort, move the machine to the edge of the
rst stair of the ight (Fig. 28/a).
2nd phase: Activate the descent pushbutton until the
STOP (placed on the base of the truck) coincides (Fig.
29/a) to the edge of the rst stair (Fig. 29/b).
3rd phase: turn softly the machine according to the
descent direction (Fig. 29/c) until it is leaned on the
rst stairs. Now, keeping the descent pushbutton pu-
shed (remember that the start is delayed of about one
second), the descent is started.
4th phase: When end of the ight is reached, once the
machine is at, press the steering bar downwards again
to activate the auxiliary wheels, then at the same time,
push and turn the machine placing it again on the edge
of the rst stair of the next ight (see Fig. 30), paying
attention to stop on the STOP. Now the 3rd phase can
be carried out again.
WARNING: ALWAYS HOLD THE STEERING
BAR FIRMLY!

12.2) Rise
1st phase: Remember that moving the machine on the
plane it’s required to exert a soft pressure downwards
on the steering bar (Fig. 31/b), approach the machine
to the rst stair of the ight (Fig. 31/a) taking care of
keeping the machine in axis to the staircase.
2nd phase: Now keeping the rise pushbutton pushed
(remember that the start is delayed of about one se-
cond), start the rise.
3rd phase: Once the last stair is reached, stop the
machine making the STOP (placed on the base of the
truck) (Fig. 32/a) coincide to the edge of the stair (Fig.
32/b), then lean softly the machine on the landing tur-
ning the machine as shown in Fig. 32/c.
4th phase: When the top of the ight is reached, once
the machine is at, press downwards on the steering
bar again to activate the auxiliary wheels, then, at the
same time, pull and turn the machine approaching it
again to the rst stair of the next ight, paying attention
to place it in axis to the staircase (see Fig. 33). Now,
rise the next ight or, if the nal destination is reached,
release the wheelchair.
WARNINGE: ALWAYS HOLD THE STEERING

13) REVERSIBILITY OF SAFETY COUPLINGS
In business there are not only wheelchairs equipped
with thrust handles (Fig. 34/a) but also wheelchairs in
which the rear thrust system consists of a shackle (Fig.
35/a) placed in the rear part on the seat back.
In these cases the safety couplings (Fig. 36/a), because
it is equipped with a second hole (Fig. 36/b), can be
rotated of 90° so that the red hook (Fig. 36/c) grasps
the shackle from downward and not laterally, clamping
the wheelchair to the steering bar with the same safety
of the traditional wheelchairs.
In order to carry out this operation follow this proce-
dure:
1) remove the clamping screw placed in the edge of
the steering bar (Fig.36/d) and loosen the locking
handwheel (Fig. 36/e);
2) extract the safety clamp (Fig. 36/a) toward the out-
side (Fig. 36/f);
3) rotate the safety coupling (Fig. 37/a) of 90° (Fig.
37/b), to the left for the left one and to the right for
the right one;
4) insert the rotated coupling through the hole (Fig. 37/c)
into the arm (Fig. 37/d). Screw again the setscrew
placed in the edge of steering bar arms, previously
unscrewed;
5) approach the steering bar (Fig. 38/a) to the seat back
of the wheelchair (Fig. 38/b). Pull the safety piston
(Fig. 38/c), hook the shackle (Fig. 38/d) using the
hook (Fig. 38/e) and release the piston (Fig. 38/c).

NOTE: ensure that the piston (Fig. 38/c) is placed
under the red hook (Fig. 38/e) so that it can’t be
released from the wheelchair (Fig. 38/d);
6) lock the coupling turning the handwheel (Fig. 38/f).
7) lift the arms (Fig. 38/g) until the point in which the red
hook (Fig. 38/e) is placed in contact to the shackle
(Fig. 38/d) is reached.
