The following maintenance should be carried out monthly, or more frequently during times of heavy usage.

All maintenance should be recorded in the maintenance log book kept in the rear of the machine.
Check water level on gauge on the rear of the chiller. Top up if needed using de-ionised water. A container of "Just Add Water" is available behind the laser.
Open the filter/vents on each side of the chiller and vacuum or brush clean of dust.

Wipe all mirrors and lens clean using soft glasses (spectacles) cloth. If there are an stubborn marks on the lens or mirrors a little isopropyl alcohol may be used.
Take care when handling the lens, as these are easily broken if dropped.

Follow the beam alignment guide on the Just Add Sharks site to check and adjust alignment of the mirrors.
