PROCEDURE TO RE-ASSEMBLE MACHINE
1. Turn the stairclimber drive screw (20) so the ballnut (19) is positioned
approximately halfway along the drive screw (20). Slide the outer frame over the
inner frame from the handle end.
2. Grip the drive screw (20) and rotate to engage the coupling (22) with the spline
on the stairclimber motor. The bearing retainer can now be fastened to the inner
frame with ¼” bolts (23) and nuts (24).
3. Re-assemble the toeplate to the outer frame with four ¼” carriage bolts and nuts.
4. Re-attach the load carriage motor with two ¼” bolts and nuts.
5. Pass the guarded wire assembly back through the hole behind the load carriage
motor and re-connect the wires to the motor. Replace the three wire assembly
clips retaining the wire assembly to the outer frame.
6. Turn the load carriage drive screw (20) so the ballnut (19) is positioned
approximately halfway along the drive screw (20). Slide the load carriage frame
over the carriage inner frame from the handle end.
7. Grip the drive screw (20) and rotate to engage the coupling (22) with the spline
on the load carriage motor. The bearing retainer can now be fastened to the
carriage inner frame with ¼” bolts (23) and nuts (24).
8. Reset the circuit breaker and operate.
9. Adjust ballnut locknuts properly. Tighten ballnut locknut (15) hand tight only, then
tighten the set screws (16).
10.
Test the machine for smooth operation.
NOTE: Ballnuts must spin in the ballnut bracket when machine is operated to its limit in
either direction. Re-adjust the ballnut locknut (15) if necessary.
11. Test the machine for proper brake action. This test should be performed with a
minimum load of 300lbs (140Kg). Braking of the load should be heard to start
immediately upon release of the switch.
12.
Re-install the motor guard and then the screw guard.
