2. Check the On/Off Switch to switch the device on/off.
4. Switch on the device and double check its operation:-
1. Slight motor noise is normal.
2. Heating of motor is normal.
3. Heating of AC adapter is normal.
4. Dildo stroke is approximately ~ 12 cm (5”).
5. Frequency is approximately ~ 90 RPM. (Double speed version - 90-50 RPM)
5. Switch off the Knapsack device with On/Off switch after testing (and after every use!).
6. If something works incorrectly – check the device to be assembled correctly and adjust as necessary.
7. I case of any problem – see the item 10. “Possible malfunctions”

1. The Knapsack device has outer moving parts – Upper lever and Main lever with Dildo-holder. User must be careful with moving parts not to touch them during use.
2. There are several "Danger points", where body parts (hands or fingers) could be trapped by moving levers (See Pic.4). Don't touch points (1), (2), (3), (4) by hands or fingers while work of device.

   

3. Points (2), (3), (4) have lubricated axles – Don’t touch them – so as not to soil hands!

1. Knapsack device is attached to the lower part of a back and fastened with belts across the waist and legs. First time, user will have to adjust the dildo position before use! We recommend the next putting on procedure. (if somebody can help You to put it on – the procedure is very simple):
2. First, switch on a Knapsack device for a several cycles and find the position of the Main lever, when dildo is in the furthest position from the body (See Pic.5). Switch off the device at that moment to fix the Main lever at this, the furthest position.



3. Place the Knapsack on an edge of a table in vertical position, with levers down and pillow directed toward your back (See Pic.6.).
4. Fasten the Waist belt around the waist, and find the optimal belt length by moving fastener. Fasten it tightly enough, but not more than necessary.
5. Fasten left and right Legs belts around legs. Find optimum belts length with fasteners. The Knapsack is now positioned ready for testing on the body.
6. Insert a dildo as required. If dildo is too close and cannot be inserted – unfasten Waist belt and pull down the Knapsack device, holding it by Waist belt (Knapsack may be supported on a table). Insert the dildo and raise the Knapsack to previous position on the waist, and fasten Waist belt again.
7. Check that all belts are fastened firmly, but comfortably.
8. ADJUST DILDO POSITION.
1. Adopt a convenient pose and switch on the Knapsack device for one cycle, to check the dildo position (too close, or too far).
2. Dildo position may be adjusted forward-backward on a dildo-holder by screwing the Vac-U-Lock attachment on-off the bolt of dildo-holder. Up to 8 cm (4”) of adjustment is possible.
3. The upper-lower dildo position (for example, for anal use) can be adjusted by placing the Arm on the closer position on the Main Lever (There are additional adjusting hole, see Pic.2.).
9. Switch on a device and check the dildo position while in motion, and adjust as necessary until the desired position is found.
