'''Coolant''' | |||
Coolant to water concentration must be checked at [SCHEDULE] | |||
[https://tormach.com/docs/download/assetlink/asset_id/24 | Portable refractometer instructions] | |||
Tank capacity: 6.5 Gallons / 24L | |||
Coolant must be: | |||
*Biodegradable | |||
*Synthetic | |||
*Water based | |||
*NO OIL | |||
*Should be compatible with both ferrous metals and aluminum. | |||
Currently selected coolant: | |||
*Qualichem XTREME CUT 250C | |||
*Source: torontolube.com, Alan at customerservice@torontolube.com - 1 gallon jug is all we need, which is below their minimum quantity - but they made an exception. | |||
*Dilute to 8-10% by adding concentrate to tap water (not the other way around!) | |||
