1 INTRODUCTION AND KEY FEATURES
Congratulations!
Thank you for purchasing the Magliner HD Powered Stair Climbing Hand Truck.
You have chosen a unit especially designed for carrying loads of up to 725 lbs. using
the very latest stair climber technology for negotiating different types of steps and
stairs safely and efficiently. The HD Powered Stair Climbing Hand Truck is safe and
easy to use.
Key features:
Two UP / DOWN switches - one on the left and one on the right of the handle
unit - for perfect user comfort. Ideal for both left- and right-handed operators.
Automatic braking system that ensures the main wheels stop reliably at the
edge of each step from the moment the unit is switched on.
Optimum protection against impact to the support wheels thanks to a lubricated
mechanical clutch.
Additional electronic protection prevents damage due to overloading.
Climbing speeds and two operating modes (single-step mode and continuous
mode) to perfectly match your operating style.
Excellent performance on spiral staircases.
1.1. General safety guidelines
Make sure nobody is located underneath the load.
Always secure the load with the safety belt included.
Always wear non-slip shoes. Some steps may be very smooth.
Always wear shoes with steel toecaps.
The HD Powered Stair Climbing Hand Truck may only be operated by trained
personnel.
Never reach into the unit's transport mechanism with your hands.
Plan each journey on the stairs according to the current situation before you start.
Always remove the battery pack before stowing the HD Powered Stair Climbing
Hand Truck. Firstly so the unit cannot be switched on inadvertently during transport
and secondly because the unit is 9 lbs lighter without the battery pack.

(Figure 4)
2.4.1. ON/OFF and Single-Step/Continuous mode multi-function switch (P)
The HD Powered Stair Climbing Hand Truck is ready for operation after the battery
pack has been switched on (ON/OFF switch on power pack) and you briefly press
button P. This is confirmed by the green LED display on the control unit going on.
The unit is in Single-Step mode.
If you briefly press button "P" again the unit switches to Continuous mode. This is
signalled by the LED flashing green.
Pressing the button for longer than 3 seconds switches the unit off.
2.4.2. LED display
Green light on: HD Powered Stair Climbing Hand Truck is in Single-Step mode.
Pressing one of the UP/DOWN switches (see Figure 5, page 11) starts the unit
moving. The unit switches off automatically after one climbing cycle has been
completed (raising or lowering the HD Powered Stair Climbing Hand Truck one
step).

IMPORTANT: Keep pressing the UP/DOWN switch in Single-Step mode until the
HD Stair Climbing Hand Truck reaches the next step and stops automatically. Then
release the switch. Pressing the switch again starts the unit on its next movement
cycle. If the switch is released by mistake during a cycle, simply press the
UP/DOWN button again to continue the movement. The unit continues operating
until it reaches the end of the cycle and stops automatically. Releasing the button
and pressing it again starts the next climbing cycle.
Flashing green: The unit is in Continuous mode. For users with plenty of
practice. The unit starts climbing when the UP/DOWN switch is pressed and
doesn't stop until the UP/DOWN switch is released.
Flashing red: The unit is overloaded. (The LED flashes for approx. 3 seconds
and then goes out –see also Operation section (4.2.1)
Alternating red and green: the battery pack is running low and urgently needs
to be recharged. The stair climber could manage another flight of stairs, but it is
recommended that you move down stairs and either change the battery pack or
recharge it with the quick charger supplied. In addition, an integrated beeper
provides an acoustic signal to indicate that the battery charge is low. The beep
frequency increases as the battery level depletes.
2.4.3. Speed switch
Use the speed switch to select higher or lower climbing speeds.
(Figure 4, page 9)
The lower speed or single-step mode is recommended for beginners, heavy loads
and difficult situations.

2.6. Main switch
The main switch is located on the quick-change battery pack. The power supply to the
unit can be switched off safely using the main switch (Figure E).
2.7. Switching off
The unit can be switched off in the following ways:
Removing the quick-change battery pack (see Section 3).
Using the main switch on the quick-change battery pack (see Figure E, 2.6).
Pressing multi-function switch P for longer than 3 seconds.
Leaving the unit for a period of time: The HD Powered Stair Climbing Hand Truck
switches off automatically after 10 minutes.
Using the main switch or removing the battery pack provides a higher level of
safety than switching off using switch P or leaving the unit to switch off
automatically because switch P could easily be actuated inadvertently,
causing the machine to switch on.
Figure E
Always switch off the main switch on the battery pack before stowing the
unit away.

4. Operation
4.1. Climbing UP stairs
Fit battery pack, switch main switch to ON, press briefly on multi-function switch P until
the LED display goes permanently green (Single-Step mode, refer to Section 2.4.1.),
or flashes green (Continuous mode).
The HD Powered Stair Climbing Hand Truck is now ready for operation.
Pressing one of the UP/DOWN switches Q (Figure 5, page 11, left and right of
handlebar, arrow upwards points towards operator) starts moving the lift arm with the
support wheels and lifts the unit onto the next step. The cycle is repeated until the
switch is released (Continuous mode, LED flashes green). In Single-Step mode the
unit stops when the main wheels reach the next step.
Important:
As soon as the main wheels have "landed" on the next step, always draw the
unit away from the edge of the step and contacts the step above.
4.2.Climbing DOWN stairs
Fit battery pack, switch main switch to ON, press briefly on multi-function switch P until
the LED display goes permanently green (Single-Step mode, refer to section 2.4.1.), or
flashes green (Continuous mode).
The HD Powered Stair Climbing Hand Truck is now ready for operation.
Pressing one of the UP/DOWN switches Q (Figure 5, page 11, left and right of
handlebar, arrow downwards points away from operator) starts moving the lift arm with
the support wheels and lowers the unit onto the next step. The cycle is repeated until
the switch is released (Continuous mode, LED flashes green). In Single-Step mode
the unit stops when the main wheels reach the next step.
4.2.1. Overload
If the unit is overloaded the drive motor stops and the LED flashes red for 3 seconds
before going out. The unit has to be switched on again.
If the power of the battery pack is running out then the overload signal will be
displayed even on loads below the specified capacity.
Important:
As soon as the main wheels have landed on the step, always push the
HD Powered Stair Climbing Hand Truck to the edge of the next step.
The brake wheels stop the unit reliably on the edge of the step.

Page 15
4.2.2. The HD Powered Stair Climbing Hand Truck is not a rubber mat!
Never throw a load onto the HD Powered Stair Climbing Hand Truck. We recommend
that this kind of loading method is avoided because it causes higher wear and may
damage the unit’s control unit as a result of vibrations.
4.2.3. Do not ride over curbs at an angle
Always ride over curbs or similar edges with both wheels contacting the edge at the
same time. This will prevent damage to the drive unit.
4.2.4. Operation on spiral staircases
Please observe the following points when operating the stair climbing hand truck on
spiral staircases:
The HD Powered Stair Climbing Hand Truck moves inwards when climbing up, so:
For climbing UP start on the outside of the staircase.
The HD Powered Stair Climbing Hand Truck moves outwards when going down, so:
For climbing DOWN start on the inside.
If you start moving too close to the banisters/wall then shift the unit to the side by
reversing (on a landing or wider step if possible) and start again at a tighter angle.
5. How the HD Powered Stair Climbing Hand Truck edge braking
system works:
5.1. Enabling the system:
The edge braking system is enabled automatically as soon as the HD Powered Stair
Climbing Hand Truck is switched on using the "ON/OFF" switch (Figure 4, page 9). This
ensures that the brake blocks inside the rims of the main wheels block the main wheels
as soon as the unit approaches the edge of a step. The brakes are released mechanically
as soon as the main wheels contact the next step. The brake system remains active and
engages automatically when the main wheels approach the edge of the next step.
5.2. Deactivating and blocking the edge braking system:
The edge braking system is blocked if the HD Powered Stair Climbing Hand Truck is
switched off using the "ON/OFF" switch (Figure 4, page 9 - LED is no longer green or
flashing) and the unit is parked on its toe plate.
The HD Powered Stair Climbing Hand truck then no longer stops automatically at
the edge of a step.

Page 16
NOTE:
It is a good idea to deactivate the brake system on uneven ground because
bumps or dips in the ground would otherwise cause the main wheels to be
stopped if one of both of the edge brakes were activated.
IMPORTANT:
Make sure that the system is switched on again before starting each movement
downwards to the next step.
This is indicated by the LED changing to green or flashing green (see section
2.4.1. for operating modes). Only then is the edge braking system enabled.
5.3. Automatic switch-off after extended period of no operation
Please note that the HD Powered Stair Climbing Hand Truck switches off automatically to
save the battery pack after approx. 10 min without the UP/DOWN switch being pressed).
The edge braking system is also deactivated (providing the unit is parked on the toe
plate).
IMPORTANT:
Always check the status of the LED when starting moving again after a pause
(LED must be green or flashing green). Only then is the edge braking system
engaged.
NOTE:
Do I have to make sure the edge braking system is activated on every step?
No, you only have to approach the edge of the step.
Hand width rule: It is enough to position the HD Powered Stair Climbing Hand
Truck roughly one hand width away from the edge of the step (distance between
point main wheels contact step and edge of step, i.e. approx. 2.75” –3.15”). Now
you can start the next lifting cycle and the unit will land safely on the next step.

Page 17
5.4 How to test the step edge braking system
Correct functioning of the step edge braking system is essential for safe operation of the stair
climbing system.
It is therefore essential that you check the function of the step edge braking system each time
before you use the stair climbing system.
1) Test the step edge braking system (without load):
a) Tilt the HD Powered Stair Climbing Hand Truck back until it is at an angle of approx.
45°. (Photo 1)
b) Switch on the stair climbing system by pressing the main switch.
c) When you push the unit forward, the step edge braking system should engage to
brake/stop the main wheels of the stair climbing system.
d) If the brakes do not engage uniformly (uneven braking on left and right wheel), do not
use the HD Powered Stair Climbing Hand Truck for climbing stairs until it has been
checked by an authorised Sano technician.

6. Charging the quick-change battery pack
The lead gel cells inside the battery pack are maintenance-free, gas-tight and
rechargeable. Their service life depends largely on the charging/discharging cycles.
For example, it is possible to partially discharge lead batteries 1000 times, drawing
more than 200 times the full capacity of the battery, providing the battery is never fully
discharged.
Avoid discharging the battery completely. Charge the battery pack as often as
possible.
Lead batteries are susceptible to self-discharging. It is therefore necessary to
recharge the quick-change battery pack after 3 weeks, even if it has not been in use.
The charger unit supplied switches over automatically to compensation charging so it
is not possible to over-charge the battery.
Do not leave the quick-change battery pack discharged or half discharged. Always
recharge the battery immediately.
If the batteries should become damaged it is possible to have them replaced in any
reputable mechanical workshop. The old lead batteries are fully recyclable and are
not to be disposed of.
The ideal temperature for charging is between 68 and 77° F. Temperatures that are
too cold or too hot will affect the battery's capacity.
If the battery pack is not fully charged, or it loses its charge suddenly, not only
will the speed of the HD Powered Stair Climbing Hand Truck be slower, but its
capacity is reduced as well. This means that overload may be displayed even
with a relatively light load. See Operation [4.2.1]

6.1. Charger unit
The battery charger supplied is extremely powerful thanks to an automatic 2-stage system
and digital control technology. The first stage is quick charging and the second stage is for
maintaining the charge. You can also check whether the battery pack is charged or not.
Features clear LCD display and pivoting mains adapter.
6.1.1. Testing the battery pack
Simply connect the charger to the battery pack (without the charger being connected to the
mains). After approx. 9 seconds one of the following test results is displayed (static voltage
of battery pack):
100% - fully charged battery pack ready for use
80 %
50%
20% battery pack needs to be charged
0% - flat
6.1.2. Charging
1. Connect the charger to the battery pack
2. The static voltage of the battery pack is displayed
3. Connect the charger to the mains
4. The charging procedure starts
The charging status of the battery pack is indicated by flashing bars:
fully charged, 100 %
approx. 80 %
approx. 50 %
0-20%

Page 20
Compensation charging
When the battery pack is fully charged the charger switches go compensation
charging mode. The display shows the battery symbol with 4 bars.
If the charging procedure does not start there are two possible causes:
Display: Symbols and flash alternately ... battery is connected the wrong way
round
Display: Symbols and flash alternately ... Contact between charger
and battery pack has been interrupted –there is a contact problem.
Check the charger cables, contacts, battery pack, etc.
6.1.3. Safety systems - technical data
