Care and Maintenance of your Molspin equipment
This page covers:-
Spinner Magnetometers (Minispin and Large Sample MiniSpin
Demagnetizers (Standard and High Powered)
Spinner Magnetometer
Dos and Don'ts:-
Do protect the spinner from rain or very high humidity - it is not waterproof!
Do take care to ensure the charger is used in a dry environment.
Do protect the spinner from abrasive or corrosive particles.
Don't drop your spinner. It is ruggedised but it is also a sensitive instrument!
Don't allow the leads or the plugs to get wet - you will get some odd readings.
Don't put items other than the samples in the spinner.
Don't put magnets or magnetized tools in the spinner.
Cleaning the equipment:-
The outside of the equipment can be wiped down with a soft damp cloth. Obstinate marks can normally be removed with a little abrasive cleaning cream like Cif. Bleaches or acidic cleaners should not be used.
The inside of the shield should be monitored to prevent the build up of particles or other dust/detritus. Such materials may interfere with the results you obtain and should be removed. Do this gently using a vacuum cleaner hose attachment.
Maintenance:-
Your spinner should require little or no maintenance. The only item that does is the lower bearing of the rotating mechanism which should be given a drop of oil every two to three months. Too much oil will affect the operation of the spinner. To add a drop of oil to the lower bearing:-
- Remove the spinner from the protective enclosure.
- Loosen the screws holding the rotation sensors (either side of the toothed metal plate) and move the assembly aside.
- Loosen the screw holding the restrictor collar and move it down the rotating shaft.
- Raise the entire shaft assembly to expose the bearing and a drop of multi-purpose light oil. Do not use heavy oils.
- Replace the shaft assembly and ensure the bearing is correctly seated ensuring the drive belt can be fitted.
- Replace the restrictor collar and tighten the retaining screw.
- Replace the rotation sensor and ensure the toothed wheel is as deep in the sensors as possible without preventing free rotation.
- Tighten the rotation sensor screws.
- Manoeuvre the belt into the groove at the bottom of the white plastic boss under the toothed wheel.
- Keeping the belt in the groove on the white plastic boss, fit the belt into the groove on the motor pulley.
- Check the instrument functions correctly. If not adjust the rotation sensor position.
- Return the spinner to its protective enclosure.

Demagnetizers
Dos and Don'ts:-
Do protect the demagnetizer from moisture or very high humidity - it is not waterproof!
Do operate in a dry environment - it is mains powered.
Do ensure the vacuum cooling system is used whenever the unit is operated.
Do be careful when moving or handling the demagnetizer - it is very heavy!
Do check that the tumbler system operates freely and does not catch on the coil former.
Don't operate the unit with the top (shield) off the unit.
Don't put items other than the samples in the demagnetizer.
Don't put metal objects, tools, magnets or magnetized tools in the demagnetizer.

Maintenance:-
Your demagnetizer should require little or no maintenance. The only item that may do is the vacuum cleaner collection container. This should be emptied when a reduction in vacuum power is detected or the shielded coil on the top becomes too hot. To empty the vacuum cleaner, follow the instructions provided or this link.
Pulse Magnetizer
Dos and Don'ts:-
Do protect the pulse magnetizer from moisture or very high humidity - it is not waterproof!
Do operate in a dry environment - it is mains powered.
Do be careful when moving or handling the pulse magnetizer - it is very heavy!
Don't operate the unit outside of its protective container.
Don't put items other than the samples in the pulse magnetizer.
Don't put metal objects, tools, magnets or magnetized tools in the pulse magnetizer.
Don't attempt to service this equipment - dangerous voltages and currents inside!
