Liftkar PTR I 18
4.5 TILTING ANGLE SENSOR
Your LIFTKAR PTR is equipped with a tilting angle sensor, which detects the inclination of the LIFTKAR PTR on
stairs. In the case that the stair angle exceeds 35°, the device clearly reduces its driving speed and the LED on
the handle unit illuminates permanently red. In the event of an extreme stair angle, the unit stops climbing
upstairs. (A warning tone as well as the red illuminated LED signalizes this condition.)
It is still possible to move downstairs in creep speed in order to bring the PTR out of the danger zone onto the
next landing.
Never move on stairs with an inclination of more than 35°.
The integrated tilting sensor does not substitute a check of the stair angle by the operator before the first
movement.
4.6 BATTERY STATUS WARNING
In case of low battery level, the LED on the handle unit starts flashing red/ green, as well as an alternating
warning tone alerts the operator. It is still possible to drive 3-4 levels after the first alert.
4.7 RECOMMENDATION FOR CHARGING THE BATTERY PACK
The lead gel cells inside the battery pack are maintenance-free, gas-tight and rechargeable. Their service life
depends largely on the number of 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. The battery pack also needs to be looked after in that it
must always be fully-charged. Completely discharging the battery will shorten its service life. Lead-gel cells
have a long service life if they are regularly fully charged as soon after use as possible. That is why the
battery pack should be connected up to the power connector cord after each use.
If the lead acid batteries have been damaged, they can be replaced at authorized SANO dealers. The old lead
batteries are fully recyclable and are not hazardous waste. If the batteries should become damaged it is
possible to have them replaced in a workshop of authorized SANO partners. The old lead batteries are fully
recyclable and are not to be disposed of.
The ideal temperature for charging is between 20 and 25° C. Temperatures that are too cold or too hot will
affect the battery's capacity.
NOTE
If the battery pack is not fully charged, or it loses its charge suddenly, not only will the speed of
the Liftkar PT be slower, but its capacity is reduced as well. This means that overload mode may
be reached even with a relatively light load.
