Trouble Shooting
Dumbbell Handle Will Not
Insert Easily Into Weight
Plates - Sticking
Nautilus Health & Fitness Group
Explanation: The dumbbell handle should slide into the weight plates with little to no additional force
required. If the dumbbell will not insert into the standing weight plates and resistance is felt, there is
likely something incorrect about the set up.
Problem: The extra force required to insert the dumbbell handle is not correct and the cause must be
determined and fixed in order for the dumbbell to operate correctly.
The following information will help you determine what may be causing the handle to stick, how to
resolve it and to return the unit to proper functioning condition.
Assure that both adjustment knobs
are set to the 5 lbs selection.
Completely remove
handle from dumbbell
base while set at 5
lbs. Did any weight
plates get lifted with
the dumbbell handle?
YES
Carefully pull on the weight plate(s) that were lifted
with the handle, they should not be attached to the
handle, you should be able to pull them free.
Reinstall the removed plates back into
the base. Be certain that the plates are
installed in the base with the “selection
tongue” facing away from the dumbbell
handle, as pictured in the owner’s
manual page 6.
NO
Confirm that all weight plates are
installed into base with the “selection
