Do not run for more than 1 hour at a time, this apparently damages the machine.
Use the basket to hold items when possible.
Do not use without at least 7cm of fluid in the tank.
The more items in the tank simultaneously, the longer it will take to clean them.
Keep the lid on during use to reduce splashing.
Don't immerse the machine or the power cord in liquid.
Don't touch the power cord with wet hands.
Do not fill while plugged into the mains.
Don't get water over the control panel, or if you do, wipe it off.
Take care when removing items from the cleaner as the water can get hot.
If using solvents other than distilled water, place the items you are cleaning and the solvent in a ziploc bag, and then place the bag in the water.
