1. Feeding system The Knight Trainer has been designed to operate with nylon and feather shuttlecocks with cork bases both new and used and of standard size However shuttlecocks are not perfectly consistent from one to another and from one brand to another Variations in shuttles can affect consistent feeding or shuttlecock durability Also bear in mind that bad shots result if shuttles are stuck together in the feeding tube This can happen for example if feather shuttles are pushed directly from a shuttle tube into the feeding tube without separating the shuttles The solution is simply to separate the shuttlecocks as you fill the feeding tube Misfeeds From time to time the Knight Trainer will need several attempts to grab and feed a shuttlecock Very rarely it may not grab a particular shuttle even after many attempts If this happens follow these steps o Use the remote control to turn off the feeding mechanism o Turn off the main power button o If this is the last shuttle in the tube the feathers might be pinched by the pressure of the ball preventing the last shuttle from being pulled from the tube Remove the tube and reload to start another session o Otherwise verify and correct these points if applicable Is the shuttle tube properly positioned in the holder If the tube is not properly seated correct this Is the weighted ball in place at the top of the stack of shuttles This is especially important for the last few2. Drives 1 These will be similar to smashes with appropriate adjustments made to position height angle frequency and velocity in order to create the desired training Once you have a trajectory that you like tighten or loosen the drives relative to the net by adjusting the height of the Knight Trainer rather than the angle 2 Set to a frequency appropriate for the level of the player the extent of movement and the type of shot being practiced iii Drop shots 1 Position the Knight Trainer along the back doubles service line a For crosscourt drop shots position the Knight Trainer near one side line and rotate the Knight Trainer to aim crosscourt b For straight drops position the Knight Trainer at a sideline and aim straight towards the net c If someone will manually vary the placement of the drop while a player trains place the Knight Trainer at the center of the service line Set up the Knight Trainer to send a drop to one corner and the same settings will produce a good drop shot to the other corner just by swiveling the head between shots 2 Raise to maximum height 3 Adjust velocity and angle until you have created the type of drop shot that you would like to practice 4 Set to a frequency appropriate for the level of the player the extent of movement and the type of shot being practiced Knight Trainer English Manual v4 7 doc Page 12 of 23 eZ ee User Manual os o iv Clears 1 Depending on the height and depth
