| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

Boredom Buster
Color: Green
This ball has been a boredom buster lifesaver. On the first day my 15 week golden retriever puppy played with it for a good 2 hours straight. I was nervous he would immediately get bored with it but nope, he searches for it every day. It has helped with his puppy teething, he's more likely to play with this ball than come up and use my hand/arm/clothes to teethe on. The battery lasts a good amount of time and is quick to charge but I did wish it lasted a bit longer. Overall I'm very happy. We live in a top floor apartment but the noise doesn't seem to be too bad for the neighbors. It's good quality and seems durable.
Edit: The velcro for the sleeve wears out within a couple uses. It keeps falling off. It was my puppies FAV thing about the toy because of the pull tag thing. So now it's ineffective for him. Not sure if there's a way to get a new sleeve or not.
