Owner's Manual Chairman Entra Maintenance

Cleaning

Clean the wheelchair often. It is especially important to clean it after it has been
used outside. Use a damp rag with a mild soap solution to wipe off dirt and dust.
NB: Do not use a hose to wash the wheelchair with water. The electronics can
be damaged.

Wheels

Check regularly that the air pressure in the tires is correct. Fill with air if necessary.
Check of brake release
Check regularly, approx. once per month, the brake release function by enga-
ging and disengaging the brake release a number of times. Check to see if chair
actually goes in and out of freewheel by pushing the chair.

Batteries

Storage
Please note that batteries discharge of their own accord and that a discharged
battery may freeze and burst when it is cold. If the wheelchair is to be stored and
not used for a long period of time, the batteries must always be charged once
per month to avoid damaging them.
NB: The temperature in the storage room should not be less than 41 F.
If your wheelchair is equipped with acid batteries, the level of acid should be
checked regularly.
If your wheelchair is equipped with gel batteries, there is no need to check the
liquid level.
The durability of the batteries depends entirely on regular charging.
