Installation of Nose
To install the nose, place the Powered Stair Climber on its back-side. Locate the three bolts included in packaging and secure the nose to the fixed nose plate mounting bracket with a T-40 Torx wrench. The longer bolt goes in the middle.
Introduction
Weighing only 35 pounds, the Powered Stair Climber efficiently climbs at a
rate of up to 48 steps per minute. With capacities up to 375 pounds, we
promise the Powered Stair Climber will be faster than you are! The heavy duty
battery handles 220 steps at full load and over 300 steps with a half load on
a single charge. The Powered Stair Climber is able to go up and down stairs
depending on your delivery demands. Many options are available to customize
your Powered Stair Climber to meet your specific needs. Several noses, various
handles, and puncture proof tires are a few of the options offered.
The Powered Stair Climber has a mechanical clutch that prevents damage if the
unit is used to descend tairs with the controls in the ascend position. The
Powered Stair Climber features electronic overload protection preventing
operation with a load over the weight limit. The Powered Stair Climber has a
slow and fast ascending speed and one descending speed.

Controls
3.1 Model
3.2 Safety Flap
It may be necessary to use your foot to assist in tilting back your loaded
Powered Stair Climber. To do this, use the swing arm, a main wheel, or the
lower portion of the drive unit. The safety flap prevents your foot from
getting jammed under the swing arm by automatically ceasing all Powered Stair
Climber operation when depressed. To resume use if this occurs, release safety
flap and press the round up switch.
Caution !
Only turn main battery switch on after tilting the load.
3.3 Main Switch
The main switch is located on the battery cover and is used to turn the power
supply on and off (see section 3.1 Model).
Power can be shut off by doing one of the following:
- Turning the main switch on the battery unit
- Removing the battery
- Pressing the ascend / descend button for 3 seconds or longer
- Automatically after 10 minutes of non-use
3.4 Control Box
Indicator Light
- Constant green means the Powered Stair Climber is in ascend mode and the round up switch in the handle bar is active. The lifting mechanism operates when the round up switch is depressed and stops when released.
- Flashing green means the Powered Stair Climber is in descend mode and the round up switch is inactive.
- Constant red means the Powered Stair Climber is in descend mode and the support wheels move quickly to the descend position.
- Flashing red means the Powered Stair Climber is overloaded and the indicator light will flash for 3 seconds and shut off.
3.5 Safety Beep (high traffic areas)
Powered Stair Climbers purchased after December 1, 2016 are equipped with a
MESAL electronic card with a safety beep feature. To turn “on,” press and hold
the ascend/descend battery for approximately 30 seconds until you hear the
unit beep. Press and hold round up switch to ensure intermittent beeps while
in use have been activated. To turn “off” press and hold the ascend/descend
button for approximately 30 seconds.
3.6 Round Up Switch
The round up switch (see page 5) is active only in the ascend mode and turns
the lifting mechanism on and off. The swing arm assembly will begin to rotate
when the round up switch is depressed. Powered Stair Climbers purchased after
December 1, 2016 are equipped with a MESAL electronic card with a tilting
sensor that prevents the swing arm from moving when the unit is horizontal
(such as in storage during transport). This prevents accidental activation of
the swing arms.
Battery
Caution !
Always remove the battery when Powered Stair Climber is not in use and when
performing any maintenance procedures.
Improper installation and removal of battery will cause premature wear of
battery case and cause battery to fall out during use.
4.1 Installing the Battery
- Locate corner “A” on both sides of battery and slide into hook “B” on the inner part of the frame
- Snap battery forward to engage locking hooks
4.2 Removing the Battery
Pull battery upward to unlock. Battery must be lifted vertically to disengage
locking hook. Failure to lift vertically will wear locking clips and will lead
to battery falling out during operation. Do not hinge back. Lift straight up
to clear the locking hooks.
Charging the Battery
The battery-cells within the battery housing are maintenance-free, sealed and rechargeable. Their durability largely depends on the charge/discharge cycles. It is possible for instance to extract far more than 1,000 partial discharges from lead-acid batteries if total discharge is avoided.
- For this reason, avoid total discharge. Recharge as often as possible.
- Lead-acid batteries are subjected to ‘self-discharge’. For this reason, the snap-on battery should be recharged after a maximum of three weeks of disuse.
- The charger automatically switches to trickle charging so overcharging is not possible.
- Do not leave the battery discharged or half discharged. Always charge immediately after use.
- 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 optimum temperature for charging is 68 – 77 °F (20 – 25 °C). Too cold or too warm has a negative effect on the capacity. If the battery has not been fully charged or tends to lose charge too rapidly, this will reduce the speed and capacity of the Powered Stair Climber and it may go into the overload mode as a result, even with light loads
Caution !
Do not leave the battery completely discharged or half charged. Keep fully
charges at all times
5.1 Battery Chargers
There are two optional DC chargers and one AC charger available from Magline
for your Powered Stair Climber. The AC charger is included with each new
Powered Stair Climber purchase. Prior to every use, check your battery charger
for any damaged wires.
AC Charger with U.S. Blade (part number 045141K) This charger comes standard
with every Powered Stair Climber purchase.
The charger unit supplied is extremely powerful. An LED display clearly
indicates the charge status. The charge display shows whether the battery is
fully charged or not. It is advised to make sure that the battery is fully
charged before using the Powered Stair Climber.
The charge status is displayed as follows by an LED:
- If the LED is constantly red, the battery is charging.
- If the LED is constantly green, the battery is fully charged. The charger unit can remain connected after the battery is fully charged (green light) without causing any damage to the battery. The charger consumes minimal power in this standby mode (when the battery is fully charged), keeping the battery fully charged and extending its service life. All of these factors are achieved by an electronic circuit that controls and regulates the charging current sent from the charger unit to the battery being charged.

Operation
6.1 Ascending/Descending Stairs
Press ascend / descend button briefly until the indicator light shines green
continuously (see section 3.4 Control Box). The Powered Stair Climber is now
in the ascend mode. Select high or low speed.
Pressing the round up switch in the upper handle operates the support wheels
and will lift the Powered Stair Climber over the step continuing until the
button is released.
As the main wheels rest on the stair, immediately pull the Powered Stair
Climber back to touch the rise of the next step up.
Caution !
Holding the Powered Stair Climber too flat on stairs with open risers can
result in partially trapping the support wheels under the stair. This may
cause excessive pressure on the drive unit and cause unit to go into overload
mode and shut down. To resume use, press the ascend / descend button to reset.
With the support wheels in the descend position, the Powered Stair Climber can
be rolled over the step and the support wheels will lower the Powered Stair
Climber onto the next step down. When the main wheels land on the lower step,
the support wheels automatically rotate to the descend position for the
descent onto the next step, all within approximately half a second.
During the descent, the indicator light changes to constant red. After
reaching the descend position, the indicator light changes back to flashing
green.
Caution !
As soon as the Powered Stair Climber rolls off the step, be sure the main
wheels are kept against the rise until the support wheels reach the descend
position.
Just before the swing arm reaches the descending position, the support wheels
reach the upper edge of the stair and lift the Powered Stair Climber
approximately half an inch.
In the case of closed risers with low steps the support wheels may touch the
stair riser and the Powered Stair Climber could move approximately 3 to 4
inches forward. This is normal as the Powered Stair Climber prepares to
advance to the next step.
It is unnecessary to press the round up switch to descend the stairs. The
support wheels operate automatically at a set speed.
6.2 Important Operator Information
When ascending, the balance of the load changes as soon as the support
wheels start lifting the load.
Care should be taken at the point where the support wheels take the load
during ascent. There is a forward movement of the Powered Stair Climber. This
is easily compensated by tilting the handle backwards.
To eliminate any major forward movements, lower the Powered Stair Climber
backwards about 15° before the support wheels begin to lift.
Do not overload the Powered Stair Climber. Exceeding the load capacity
activates the overload mode causing the Powered Stair Climber to stop and
lower the main wheels slowly to the lower step. The indicator light flashes
red for about 3 seconds after which the ascend / descend button will need to
be reset.
Caution !
Once the battery is discharged, the unit goes into overload even with loads
below the specified capacity.
Never throw loads onto the Powered Stair Climber. The impact of throwing loads onto the Powered Stair Climber could result in fracturing the drive unit. If necessary to load the Powered Stair Climber in a horizontal position be sure the support wheels are raised between the main wheels and carefully place the item on the Powered Stair Climber.
During normal operations, the battery is held securely in place by locking hooks. A strong, vertical pull is required to remove it. Moving backwards very quickly and striking a high step or similar equipment abuse could result in the battery ejecting from its location. If this happens, the Powered Stair Climber will cease operation. Failure to negotiate steps “square-on” will damage the underside of the drive unit.
CE Marking
All Powered Stair Climber battery chargers meet the fundamental
requirements of the Low-Voltage and Electromagnetic Compatibility Directive
and is thus CEmarked.
