Step 1.
Insert one end of the cord into the hole in the rotor (fig. 1). Proceed to turn the rotor forward with your thumb, while maintaining pressure on the cord between your other fingers to make sure there is no slack as it winds up around the rotor groove (fig. 2).

Step 2.
When there are only about 3 inches of cord remaining, stop winding and hold the ball with the digital counter (tip) buried into the palm of the hand that you are going to spin the NSD Power® ball up with (usually right if right handed, left if left etc.). The exposed rotor will be facing the ceiling at this stage (fig. 3).

Step 3.
Hold the cord firmly and give it a quick, sharp tug away from the ball (as if starting a lawn mower!). Really let rip here, (don't be afraid of it!). But ensure that you always pull it straight out to minimise the opportunity for the cord to jam in between the rotor mechanism and the outer shell if pulled sideways. The rotor should now be spinning at between 2400 & 3000 rpm.

Step 4.
Immediately turn your hand over (so that the exposed part of the ball is now facing the ground) and begin to rotate your wrist (not your arm!) in a slow circular motion (fig. 4) as if you were slowly stirring a large pot with a long wooden spoon or waxing a car. The proper motion required to do this involves absolutely no movement of your arm - just the wrist joint!

Step 5.
The secret to easy starting of the ball is to begin slowly - i.e., after giving the ball a good spin with the cord, begin your wrist movement in slow, wide lazy turns (6-8 inches in diameter - about 1 turn per second). Don't start with fast, short wrist movement as you will be out of sync with the slow spinning rotor and will find it difficult to properly increase the speed. (In this manner, you will hear the rotor ’slapping’ noisily in the sphere as it struggles to find momentum).

Step 6.
As you slowly build up the rotor's speed, you will find that the pressure acting on your wrist and arm will increase proportionally as gyroscopic forces build within the Powerball®. Respond by reducing the diameter of your turning circles (3-4 inches) and increasing their speed (3-6 times each second) - the shorter the circle the wrist goes through in an effort to spin the ball, the faster you will drive the rotor and, consequently the harder it will be to do! To achieve those really high speed runs, (12,000 rpm+) it’s all about practice - not that this is going to be difficult, because your new Powerball® is totally addictive and you will find it hard to put it down once you perfect the technique!

1. Total Accumulated Revolutions
Press the ’FCN’ button to reveal the "total revolutions" mode on the display. This mode calculates the accumulated rotor revolutions during a session and records each 100 rotations as one unit - for example 7240 revolutions will display as 72.

2. ’Real Time’ Revolutions
Press the ’FCN’ button to reveal the "current revolutions" mode on the display. This counter setting allows real time monitoring of the rotor’s RPM (revs per minute) speed.

3. The Highest RPM
Press the ’FCN’ button to reveal the "high speed" mode on the display. While the rotor is stationary, this counter setting will automatically display the highest RPM ever achieved on the ball.

Once the rotor is in motion however, the mode automatically changes to the "high speed - action" setting. This will effectively record the highest score achieved during the current session.

If this is a higher score than the current record held in the counter’s memory, then the display will flash and the new score will automatically overwrite the old high score once the rotor stops turning. If the score is lower than the current high score in the counter’s memory, then it will remain on the display until the rotor stops and revert back to the "high speed" mode once again.

4. The Physical Strength Index
Press the ’FCN’ button to reveal the "strength index" mode on the display.

This setting will begin to record the number of actual revolutions made during the 30, 60 or 90 second interval immediately after the rotor is set in motion. The display begins counting down and continues until the last 5 seconds - whereby the accumulated revs will appear. This is a superb test of your strength as you need to keep the rotor spinning at the highest possible revs for a period of 30/60 or 90 seconds in order to achieve a maximum score!
