Joint Tune-Up

IS A JOINT ON YOUR MOUNT NOT UNLOCKING LIKE IT USED TO?

-ie seems frozen - stuck - not releasing - hoop operation no longer unlocks the joint easily -

.....it might be time to tune your Joint-Release Adjuster!

Background:

The Joint-Release Adjuster (JRA) was implemented (starting from Serial # 1480) to provide a simple way for you to give the joints a tune-up after extended use.

Is This What You Need?

The JRA does not affect locking strength – only the trigger for unlocking
If your Mount’n Mover has no problem releasing, but does not stay locked -  the JRA will not help. Please Contact Us
When you depress the hoop completely, and neither joint unlocks -- the release mechanism may have worn out - the JRA will not helpContact Us
This feature is only available for the elbow and shoulder. If the wrist joint is not functioning correctly, please Contact Us

LETS BEGIN:

Tools Required: 1/16” hex key (included with every Mount’n Mover)

Approximate Time Required: 15 minutes

In this example the Elbow joint won't unlock, we will adjust the elbow joint's JRA

Step 1: Move Unaffected Joint to Unlocked Position

Move the joint you aren't adjusting to a non-locked position (this isolates the problem joint so it can be adjusted)

Move the unaffected joint to a non-locked position.
In this example the Elbow needs the tune-up, so we unlock and move the Shoulder.

Shoulder moved out of lock position

Step 2: Test the Hoop for Droop

When the unaffected joint is in an unlocked position the hoop should droop/sag slightly - this indicates wear in the unlock mechanism .

If the joint does not droop Contact Us

Confirm that when the unaffected joint is out-of-lock
the Hoop droops or sags slightly. Push the Hoop up. It should drop slightly when you take your hand away

Step 3: Remove the Plastic Cover

Remove the black plastic cover over the problem joint.

Using the 1/16” Hex Key, turn the set screw counterclockwise until the screw is completely out
Remove the black plastic cover by tipping it up and pull back
Set the cover aside for now

Remove the black plastic cover from the problem joint

Step 4: Adjust JRA Screw

Find the JRA Screw in the exposed joint.
Insert the 1/16" Hex Key into the JRA Screw (found in the center of the open joint)
Keeping an eye on the hoop, slowly tighten the JRA-screw clockwise (You may feel some resistance from the loctite used to protect the screw from vibrating loose)
Watch for the hoop to move up as the JRA-screw tightened (this should be a difference of 1/16-1/8 in)

Adjust the JRA-screw (slowly turn clockwise)

Make sure to just eliminate droop in the hoop lever.

Adjusting the JRA too far may result in poor locking strength.
Please test the joint after each adjustment. Only adjust each joint so the Hoop can unlock both the elbow and shoulder joint (simultaneously and independently).

Step 5:

Test the joint to ensure the problem is resolved, then replace the black plastic cover
For the Dual Arm Mount'n Mover, repeat this process for the other joint as needed

Adjustment complete for this joint. Test to make sure joint locks and unlocks readily.
