WARNING:
ALWAYS DISCONNECT MACHINE FROM POWER SOURCE & TURN OFF HYDRAULIC PUMP BEFORE ATTEMPTING TO PERFORM ANY REPAIRS, MAKE ANY ADJUSTMENTS OR TOUCH-UP OR SHARPEN CUTTER BLADES.

BLADE ADJUSTMENT

Upon arrival of the B & D Model "350" Horn-Master cattle dehorner you will notice that the blade setting is approximately 1 mm from closing completely. This is done to safeguard the blade edges and more so as many slaughterhouses require the horn to remain attached to the head by a piece of skin, to be finally removed with a knife over a chute or suitable place away from the sticking and dehorning area.
If your requirements differ from this method and horns have to come off by the Model "350" cutter, then the blade opening can be adjusted by loosening Part No. 7 (Blade Adjusting Nut) and screwing the cylinder complete 1/2 or full turn into Part No. 18 (Head Cylinder Mount) until blades are just touching. Once this is achieved, re-lock Part No. 7 to ensure correct clearance will be maintained.
If the blade openings needs to be increased, retract blade position to "open", remove yoke screw (20) from yoke (19), push blade out of yoke slot, then turn the cylinder counter-clockwise to desired opening, after which the blade can be returned into yoke slot and cylinder secured by nut (7). The reason for this blade being removed from the yoke is due to the fact there is a possibility that by unscrewing the cylinder you may also unscrew the yoke from the piston rod. Yoke is "loctited" on piston rod so it should not happen, however, it is better to be safe than sorry.

SHARPENING BLADES

To sharpen blades - remove Part No. 25 (Head Fixed End) and withdraw blades, leaving both blade and guides secured on Part No. 18 (Head Cylinder Mount). It is most important that both blades are re-ground as per original angle and that after grinding both blade edges meet square on, otherwise proper adjustment becomes impossible.
