Dings Magnetic Group Stationary Electro Overhead Magnets - Manual (Page 10)

Revised January 19, 2011
Periodic inspection and maintenance are required. Check magnet body for oil leaks. Check
pressure relief valve (breather) on top of magnet. It should be free of dirt and obstructions. Oil
seepage from breather is no cause for alarm. It may result from overfilling.
OIL CHANGE OR REFILL
CAUTION: Allow oil to cool completely before servicing.
Oil level should appear at oil level plug hole when magnet is level. Oil should remain clear and
free of contaminants. Sludge in oil will greatly reduce service life. If oil is turbid or cloudy,
replace it. Do not mix new oil with old oil.
USE ONLY THE SPECIFIC COOLING OIL designated on the caution nameplate located on
the side of the magnet. Read this nameplate. The electromagnet contains special high
temperature cooling oil. The use of any different oil can be a fire hazard.
This magnet was originally filled at the Dings factory with the type of oil marked on the caution
nameplate. This oil is safe for use at the high temperature at which this magnet normally
operates. Do not add any amount of any other oil or liquid.
To drain oil, remove drain plug in side of magnet body near bottom. Remove fill plug in top
surface of magnet body. Drain and flush magnet clean using new oil (don’t use old oil or
cleaning solvent).
To refill, replace plug in drain hole. Remove oil level plug in side of magnet body near top.
Place magnet in level position. Fill with oil to oil level plug hole. Reinstall oil level plug and
reinstall oil fill plug. Note - seal plugs with Permatex No. 2 non-hardening. (Do not use
silicone as it is not compatible with the oil and leaks will develop).
GENERAL - Periodically check hex head set screws and bearing bolts for tightness, tighten if
loose.
