Storage of batteries
If not in use, batteries should be reloaded at least every 3 month. A very long storage time
can cause that the batteries cannot be activated any more. This storage time varies
according to previous operation, the loading state and the storage conditions.
For these reason only fully recharged batteries should be stored. Storage should occur
distant to the charger and as cool and dry as possible.
Important:
The electric discharge of the batteries increases significantly with higher
temperatures. E.g. at 38° the batteries are empty after 5 month while at 10° only 8 % of
the loading capacity would get lost. Batteries can be stored at temperatures down to -20°.
Rubber crawler
Parallelism
It is important that the lugs of the rubber crawlers are parallel to assure that they both
touch the steps simultaneously.
Attention:
If they are not parallel the
Stairmax
may not climb the stairs in a straight way
and this can lead to a loss of balance. If the parallelism is not given please inform your
Stairmax
supplier for adjustment of the rubber crawlers.
Cleaning of the rubber crawlers
To achieve a maximum of friction between the rubber crawlers and the steps it is important
that the rubbers crawlers (and the steps) are clean and free of oil or dirt. The rubber
crawlers can be cleaned with wet towels or mild cleaning agents. It has to be assured that
cleaning agents don’t damage the rubber. We advise, independently of the steps, to clean
the rubber crawlers at least 2 times a year. Please also thoroughly clean the stairs
regularly.
Use of new rubber crawlers:
The rubber crawlers contain steel-wires that impede the overstretching of the rubber.
These wires are covered by a thick rubber layer. The rubber crawlers are extremely
durable but should be exchanged if they have cracks or cuts or other signals of damage.
Exchange is also necessary if the rubber lugs are worn off and significantly smaller
compared to their initial state.
