	The turbine bearings in the BenchJewel Rotary are traditional bearings that are more durable than oil less type bearings. Traditional bearings require oil. If you are working on a project and are working it hard it is recommended to give the bearings a drop or two of oil every few hours.
	Use the supplied oiler to deliver a drop or two of oil. To do this: 1:Turn the ring to match the red dot on the body with the lubrication hole. 2: Place a drop of oil by inserting the oil dispenser to the lubrication hole. 3: Next rotate the ring to un-match the red dot on the body with the lubrication hole, and the tool is ready to go back to work.
	Oil does come with the handpiece, however if you run low more can be purchased. Use the this to refill the oil dispenser that came with hour handpiece. Rotary Oil, 1oz $10.00
	To insert a bur. Insert the shank of the bur in the nose hole. Place supplied insert tool over the bur. Use it to push the bur the rest of the way in. To removed a bur use the push plunger on the end of the handpiece to push the bur out. Be sure the shank of the bur is clean and rust free. If there is corrosion or damage to the shank of the bur do not insert it as it could damage griper in the handpiece.
	Be aware that continuous hard side pressure on a bur without oiling every few hours will shorten the life of the turbine bearings. Generally cutting background out as shown in the video above on this page by Steve Lindsay is considered fairly gentle use. Be careful not to drop the handpiece. If it were to land on the nose it could damage the \ bearings or collet nose, requiring the handpiece to be returned for repairs.
