CYLINDER ADJUSTMENT
NOTICE: CYLINDERS ARE FACTORY-ADJUSTED AND REQUIRE NO
FURTHER ADJUSTMENT UNLESS THEY ARE REPLACED. Please contact
KEISER if you have any questions concerning adjustments or repairs.
1. Check the condition of the rubber crutch tips that the exercise arms rest against.
These must not be worn or damaged in any way. If they are worn replace them
before attempting to adjust a cylinder.
2. With the resistance at zero, disengage the arm lock shaft so the exercise arms can
move independently. Remove the crutch tips from the arm stop shafts and loosen the
jam nuts on the adjustable arm stop and cylinder shafts.
3. Push the right exercise arm back towards the arm stop shaft. NOTICE: BE
CAREFUL NOT TO SCRATCH OR DENT CHROME. Turn the right cylinder shaft
as needed to bring the arm to a point just touching or slightly away from the stop
shaft. Tighten the right cylinder shaft jam nut.
4. Increase the resistance very slightly (just enough to hold the exercise arm in the
starting position) and turn the left cylinder shaft to a position where the arm lock shaft
engages easily. Turn the adjusting screw in the left stop shaft to the same position as
the right (touching or slightly away from the exercise arm). Tighten the jam nut on
the stop shaft.
5. Decrease the resistance back to zero and replace the crutch tips. Test the adjustment
by doing several repetitions on the machine at different resistance checking for a
“bottomed-out” cylinder (which feels hesitant or sticky), then try the arm lock at
several resistances. If the arm lock does not work smoothly at all resistances, adjust
the arm stop in or out slightly as needed.
