Bench Grinder - Scantool
Induction Required
This equipment requires an induction prior to use. For your own safety and to avoid damage to the equipment do not attempt to use it until you have been inducted.It's a two part induction. There is an in-person induction which will take no more than an hour. Please read the wiki before your in-person induction. Once you complete the quiz (on the enrollment portal pc), you should be able to turn on the bleepy box

Instructions
Before starting the motor check:
End shields are secured to the main wheel guard by screws, which must be secured at all times. Wheel can be revolved freely by hand. The toolrests are in position, adjusted to within 3mm (1/8“) of the periphery face of the wheel, and firmly secured. The protective eyeshields fitted to Bench Grinders are clean and secured in the correct position, or that recommended and approved type of protective goggles, with clean lenses, are worn before operating the machine. All adjustments and checks are made with the machine disconnected from the power supply.
When starting and using the machine:
Check that the wheel, especially a new replacement wheel, is in sound condition by allowing the machine to run up to maximum speed and remain there for at least 30 seconds before it is put into use. During this check make sure that all personnel are standing clear of the machine. Allow the machine to run up to full speed before applying the workpiece to be ground. Feed the workpiece smoothly onto the grinding wheel and avoid harsh intermittent pressure and bumping onto the wheel. Always apply light but firm pressure, and allow the wheel to rotate at the maximum possible speed. Avoid excessive pressure as this will tend to decrease the wheel speed and the amount of stock removal, cause uneven wear onthe grinding wheel. Do not arrest the wheel by applying pressure to it at the conclusion of the grinding operation. Always allow the machine to run down freely to rest. The machine can be operating max. 30 min/hour.
Wheel Care
Store spare grinding wheels flat on a firm surface with a layer of compressible material between the wheels and the storage surface. Similar material should be placed between wheels when a number are being stored. As the grinding wheel is used it will wear. it is recommended that the wheel is replaced when the diameter has been reduced approximatcly 25% below the original size (e.g. 300 mm to 225 mm : 200 mm to 150 mm : 150 mm to 112 mm : and 12.5 mm to 94 mm). Wear on the wheel can cause eccentricity leading to machine vibration and bouncing of the workpiece. Unless this condition is corrected it can result in further damage to the wheel and possible harm to the rotor bearings. To obtain wheel balance and good efficient grinding action the wheel must be redressed. A suitable wheel dressing tool is avaiable under the part number 1168
General Maintenance
Always disconnect the machine from the power supply before making any adjustment to the wheels or any other attachment. Check the supply cable and replace any damaged length. Replacement cables must be of the same current rating as that originally fitted. The earth wire must always be connected an d maintained. Keep the area around the machine as clean as possible. Replace damaged tool rests and eyeshields. Failure to do this can cause accidents. Bearings should be regreased when a major overhaul of the machine is carried out.
Clean up
Sweep down the area to remove dust to debris from the grinding
