Magliner Powered Stair Climber User Maintenance Manual page 32

If the motor can be heard running but the swing arm with support wheels does not
move, inspect the drive chain (see page 9). If the drive chain is in place, then the
sliding clutch must be re-adjusted. (see Fig. 5b on page 10)
24.3 My Powered Stair Climber Will Not Lift Full Capacity
A. Charge the battery fully. When charging with DC charger (part number 930114), be
sure the main switch on battery is in the on position (see Fig. 1b on page 5).
B. Be sure no more than capacity is loaded on the Powered Stair Climber.
C. Make sure the battery contacts on both the Powered Stair Climber and the battery
(part numbers 004120 & 004121) are clean. It may be necessary to replace if
corroded beyond what can be cleaned.
D. Check battery voltage with an Ohm Meter. (see page 5)
24.4 My Powered Stair Climber Runs Very Slow
A. Charge the battery fully. When charging with DC charger (part number 930114), be
sure the main switch on battery is in the on position (see Fig. 1b on page 5).
B. Make sure the speed switch on the control box is switched to "fast" speed, which is
indicated by two solid parallel lines.
If you toggle between slow (one solid line) and fast (two solid lines) and there is no
difference in speed, pull out the control box and test with an Ohm Meter by
removing control box and popping out toggle speed switch with a flat screwdriver.
Place one prong on each of the two wires. If reading is OL, replace the control box
(see page 7). If reading is not OL, replace main wiring harness.
