Q:

Is SAE 30 non-d oil an OK substitute for the (unavailable to me) 20 wt. oil for model 758 72923 humidifier?

A:

You can use 30 weight non detergent oil in the humidifier. It will work fine as long as the room temperature is above 30 degrees.

Q:

Vacuum Cleaner stops running after approximately 5 minutes. This could be the thermal protector. Should it shut off after only 5 minutes of vacuuming?

A:

Thank you for your question as to why the vacuum cleaner is stopping after five minutes.

The vacuum motor shutting down usually is an indication that there is a partial air blockage in the tubing that the dirt travels through. The air that the vacuum cleaner picks up has to travel through the vacuum and the dirt stops at the filter and the air continue on through the motor to keep it cool. If there is a restriction the motor will over heat and shut down on thermal over load and has to cool and reset before the motor will start up again.

Please make sure all the filters are clean and the dirt and air that travels in the tubing is clean and has not blockages.

If you have to replace the motor it will come with some of the plastic housings that surround it.

Take the dirt cup out of the vacuum and turn it on to see if the motor will run for more than five minutes.

Do no vacuum with the cup removed just let it run if it will.

Please let me know what you find out.

Q:

transmission noisy and seems dry. How do you add lubricant?

A:

Thank you for your question.

I can understand your concern for the noisy operation.

  • These gearcases were a factory sealed unit and not designed to be taken apart or serviced.

  • If it does not have a zerk fitting on the side of the gear case you could carefully drill the upper side of the gear case and tap a hole for a zerk fitting and then use the synthetic plastilube grease and pump it in with a grease gun.

  • You could subtitute lithium grease if you like instead of the plastilube. If you have a leaky seal at the bottom the 90 wt will just run out.

I hope this will help.

Thank you for using Manage My Life.
