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, check the feel of the movement of the machine. If the rod
seems to stick or hesitate at full extension, the piston may be bottomed-out against the
end housing. If the piston is bottomed-out, lengthen the rod three full turns down (pg.
13 maintenance manual).
SPRING PINS
1. When installing the spring pin 3/16 X 7/8 (item # 11) into the front frame (item # 4),
line up the hole in the front frame with the hole in the exercise arm pivot shaft (item #
12). Drive the spring pin in until the end is 1/16” into the front frame.
