Step 1:  Lets get started
Choose the collet by placing tool inside it
Wipe collet seating area clean with finger
Install collet into clamp ring
Install clamp ring onto spindle leaving it loose so tool can slip in easily for set up
Step 2: :  Centre height set up
Insert the tool into collet approximately 30mm deep and lock clamp ring using C spanner
Release spindle lock and rotate spindle till zero marks line up, hold spindle against clicker device and lock spindle
With the tool edge resting on height rest use C spanner and tighten clamp ring
Wheel choice is important in this case the cup wheel will be used for both end mill and slot drill sharpening
Step 3:  Grinding wheel change
Remove and place wheel guard to one side by undoing securing screw with a 5mm allen key
Change grinding wheel by placing spanner onto spindle and rotate wheel anti-clockwise by hand
Whilst working around tools beware of sharp edges. Place a rag over tool to prevent cuts, oops !!
Tighten the clamp ring by hand using the C spanner
Step 4:  Work holding device
Both tool and wheel must be the same centre height as rest locator. Adjust accordingly
Undo lock handles 1 and 2 and tilt head to +6 degrees and retighten lock handles
Undo swivel base locking screw on right hand and reset base to zero degrees + 20 minutes relock again
Ensure cross slide setting is at zero if not use small front handle to correct zero position
Step 5:  Sharpen the tool
Grind all four primary edges at + 6 degrees to achieve a band width of 1mm
Undo clamp levers 1 and 2 again and tilt head to + 12 degrees and relock clamp levers
Grind all four secondary edges at + 12 degrees to achieve a band width of 0,5 mm to 0,8 mm
Inspect the tool if OK, then undo clamp ring  by using Ceespanner and tap gently as tool will pop out.
Tool inspection time
1.  Inspect the primary angle to meet required measurements of 0.5 mm to 0.8 mm using either a  150 mm steel rule or a Vernier
2.  Tooling may be removed to measure more accurately due to poor ergonomics.
3. If measuring in the current set-up adjust the over head light to give better vision if require
4. Always be very careful of sharp edges on the tool as you move your hands and limbs around whilst checking and inspecting dimensions on tools.
