    • This operation should only be carried out by suitably trained personnel.

      Carefully examine the new grindstone for any signs of damage such as chips or cracks. Also look for signs of water damage (a dark stain in one area that will leave a grindstone out of balance) If the stone is damaged or you are at all unsure, DO NOT use that grindstone. Make sure that the mounting surfaces of the grindstone are clean with no grit. The mounting faces of the stone carrier should be similarly clean. Tighten the retaining nut firmly.

      ALL new grindstones should be dressed after fitting. If the grindstone runs out of balance loosen the retaining nut and rotate the grindstone on it's mounting about ¼ turn. Re-tighten the retaining nut and try again.

    • Scratch the grindstone across the top face to find 0° (zero degrees). Set the protractor to the correct angle on the protractor for that blade, rotate the blade back ½ – 1 degree to allow blade to be trued up.

    • Scratch the grindstone across the worn top face to find 0° (zero degrees). Set the protractor to 0°, rotate the blade back to the 'correct angle' on the protractor for that blade.

    • By adjusting the parallel adjustment of the mounting bar apply a parallel line of cut on the blade (The width of the ground face should be equal across the blade, either side of the centre line).

    • Angles are set taking account of the current wear of the bedknife. Required angles depend upon the size of the blade (mower size) and the ground conditions. Greater angles should be applied if conditions are dirty or if top dressing is applied.

    • Always try to copy the way they sit in their own mower. Locate off the bedbar mounting points using cones into those with threaded or plain holes or cups over those, which have round boss locations to the mower frame.

    • Lines or flats may appear but they are not detrimental to the grind.

      They may not be flats – it may be some grinding debris rolled and compacted on to the rails by the carriage bearings (hence the importance of cleaning rails as part of your routine maintenance) try wiping (or gently scraping) off the debris with the assistance of WD40 or similar product.

    • So that they do not influence the shape of or distort the bedbar/bedknife during the grind.

      The magnets are a 'load assist' or 'extra hand' device. When the grindstone motor comes on, they turn off, allowing the bedknife assembly to assume it's natural shape as removed from the mower. When the grind motor is turned off the magnets come on again to assist with unloading the assembly from the Anglemaster.

    • The knife has been set too far back resulting in not enough overhang.

    • Can be due to lots of lapping or too much tightening at one end. To true it up, grind so the thickness is the same.
