29. Level the unit. Diagram 20. To keep the unit stable, the EFX
®
5.21i has adjustable
rear pads and, at the front of the base assembly, a height adjuster. Check to make
sure that the unit does not wobble from side to side or front to back.
Important: If the unit is placed on a slightly, uneven surface, adjusting the rear
pads can help, but will not compensate for extremely uneven surfaces.
a. To remove any side to side movement or wobble, rotate the rear pads.
Diagram 20, #2.
b. To counteract any rocking (front to back) motion, ask your assistant to grasp the
upper handrails so that he or she can raise the front of the unit off the floor. See
Diagram 20, #1. Use a crescent or combination wrench to loosen the nut.
Refer to Diagram 20, #3.
• Turn the height adjuster clockwise to raise the height of the front end.
• Turn the height adjuster counterclockwise to lower the height.
Once you have the proper height adjustment, use the wrench to turn the nut
counterclockwise and tighten it securely against the base tube. Diagram 20, #3
c. Have your assistant carefully lower the unit onto the floor.
30. Clean the ramp. Diagram 21. Wipe the ramp and foot pedals with a soft cloth
dampened in a diluted solution of mild soap and water.
