IMPULSE DRIVE - OPERATION MANUAL 21
Frequently Asked Questions and Possible Answers
Why has there been a sudden loss of power?
1. Undercharged batteries. Check the BATTERY indicator. The BATTERY indicator
indicates the charge condition of the batteries while you are driving. The indicator will
not indicate the “true condition” of their capacity until the bed has been setting on, in
an idle condition, for several minutes. The green area corresponds to a good charge.
The red area corresponds to a low charge, or a deep cycle discharge condition. It may
be possible to drive the bed with the batteries in a deep cycle charge condition, but once
they drop below a certain level of power they will fail and you will be stranded. If,
while you are driving, the indicator falls into the red area charge the batteries as soon as
possible. Charging will bring deep cycle discharge condition batteries up to full charge.
You will not receive maximum battery life if the batteries are routinely run to the deep
cycle discharge condition.
2. Circuit breaker on breaker box. An “Open” circuit breaker indicates some type of
drive system overload. Consult with your dealer to determine the problem.
3. Excessive weight on the bed. Remember that the Tri-Flex II takes a maximum of a
1000 lbs. (454 kg.) patient.
4. There may be other motor or driving mechanism malfunctions. Consult with your
dealer.
Will leaving the batteries for a long time damage them?
Yes. Storage of batteries is very important to their life span. The very best way to
maximize battery life is to store them in a fully charged condition in a cool place with the
charger connected. If the charger cannot be always connected then periodically (every 1-2
months!) charge to keep the batteries in the full charge condition. Do not store in cold or
freezing temperatures. Batteries should never be subjected to freezing temperatures. Under-
charged batteries can be ruined quickly in freezing conditions.
