SECTION 2—SAFETY INSPECTION/TROUBLESHOOTING
21
WARNING
When performing STEPS 5 and 6 ensure feet are clear from casters and wall other-
wise injury may result
5. Sit in wheelchair and place feet against a wall, workbench or other stationary object.
6. Turn the power ON and carefully push the joystick forward, trying to drive the
wheelchair through the stationary object.
NOTE: This puts a heavy load on the batteries as they try to push through the stationary object. If
the wheels spin, have two (2) individuals (one [1] on each arm) apply as much downward pressure
as possible on the arms of the wheelchair.
7. Read the meter while the motors are straining, no longer than 3-4 seconds, to
determine the voltage under load.
NOTE: If the voltage drops more than 2 volts from a pair of fully charged batteries while under
load, they should be replaced regardless of the unloaded voltages.
