Smallest Weight Plate
(1.25lbs) Lifting With Handle
When Not Selected
Nautilus Health & Fitness Group
Explanation: Due to the very low weight of the smallest weight plate (1.25 lbs) it is possible that this
plate, in some circumstances might be lifted with the dumbbell when it should not be. This is not
desirable since the plate is not actually selected by the inner discs and is therefore not retained and
could fall from the handle.
Problem: User removes handle from base and smallest plate (1.25 lbs) is lifted when it should not be.
Examples are the 5 lbs / 10 lbs / 20 lbs settings; these selections do not involve the 1.25 lbs plate.
The following information will help you determine what may be causing the problem, how to resolve it
and to return the unit to proper functioning condition.
Determine conditions under which the smallest
weight plate (1.25 lbs) is incorrectly selected
when the handle is removed from the base.
Does it happen at the 5 lbs or 10 lbs or 20 lbs or
all three?
Set the handle to 5 lbs for both
adjustment knobs. Remove handle from
base. Rotate handle position and
reinstall the handle so that the
adjustment knobs are now on the other
side of the dumbbell.
Repeat first test to see if smallest plate is still incorrectly
selected on the same side of the dumbbell as before. If
the plate that was a problem before, is no longer a
problem the issue may reside with the handle not the
plate
Since the plate that was sticking is no
longer sticking after rotating the
handle we must test the opposite
side. Check the opposite side to see
if the small plate on that end is
incorrectly selected and picked up
with the handle
NO - plate no longer sticking
YES - still problem
The problem may be resolved by applying a light coat of silicon
lubricant such as Schwinn Fit-Tech Lube to the outer surface of
the plastic. If this fails to resolve problem then:
REPLACE 1.25 LBS WEIGHT PLATE
Since the sticking problem has moved
with the position of the dumbbell
handle it seems the problem is a
tolerance issue with the handle. The
problem may be resolved by applying
a light coat of silicon lubricant such as
Schwinn Fit-Tech Lube to the outer
surface of the plastic. If this fails to
resolve problem then:
REPLACE HANDLE
YES - sticking
Example of 1.25 lbs plate wedged in backwards.
Selection tongue on wrong side and only held in
with friction. User can simply pull plate out by
hand.
