LOOSE SELECTOR DIAL

Speed selector may have failed.

could be a loose contact on the speed selector..

Here's what you need to do first. Check and make sure the bottom nut on the agitator shaft or planetary shaft is tight (This is the part that the attachments afix to). NEXT, take off the lid exposing the top area. THEN tighten up the largest nut (TIGHTENING is in reverse! SO - TO tighten turn nut to the LEFT). When the nut is tight, then turn on the mixer in 1st gear. IF you still do not have 1st gear, then turn off unit and THEN loosen (By turning to the right) this nut by a 1/4 turn or so, then turn on mixer again -- check for 1st gear. If after loosening this nut to where there is no resistance at all and you still do not have 1st gear, then you may have a sheared KEY on one of the gears that controls 1st gear! Did you hear anything pop or break before this happened? Let me know.

First, you may want to adjust the mixer's speeds:

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Second, if the mixer won't run:
Remove the Control Plate Assembly (36), the Phase Control Board (39)
and the motor Governor Assembly (35). Inspect for loose connections,
burnt or damaged components. If they seem to look OK, re-assemble
them and test the mixer. If the motor still won't run, then I might suspect
a defective Phase Control Board (39).

Inspect all the moving parts: Speed Lever, Speed Link, etc. and
make sure nothing is loose, bent or broken. Tighten all the screws
if necessary. Finally, adjust the mixer speeds if needed:

Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

Hello Ldl,

I understand that you are having a problem with you 5 quart commercial mixer by hobart. The 1 and 2 are the same speed and you are not getting 3. You also would like to know what oil to use in your machine and how to fill the unit.

To answer you speed question first. The speed is adjusted by the bolt located in the middle of the planetary (the part that turns underneath of the head the attachments hook to). If this bolt is tightened all the way up or to lose it will not allow you to achieve all of the speeds. You will have to adjust this screw many times and turn the machine on to check you speeds. Eventually you will achieve all three speeds.

Before I answer how you lube the machine you need to know what kind of lube to use. The gear box uses a 90 weight gear oil and the planetary uses 140 weight gear oil (grease).

Lubing the gear box with top cover:
1. Remove the top of the gear box (the cover)
2. There is a Round plate with three bolts (do not remove) in this plate there is a disc (looks like a cap seal) use a small screw driver to pry this disc out carefully you will have to put it back once you are done lubing the unit.
Lubing with out a top cover:
1. Remove the switch and gear selector (remember position of gear selector)
2. Fill thru whole in side behind plate removed

Lubing planitary:
1. Remove drip ring
2. Remove the planetary (unscrew bolt in middle)
3. Remove key located in the side of shaft
4. Lube and put back together

Loosen the two planetary nuts, should be a thin nut and an acorn nut. With these loose make sure the large nut on top of the transmission is tight. Push the planetary all the way up on the shaft and turn the thin nut up until snug. Back the thin nut off 1/4 turn. Hold the thin nut in position and lock the acorn nut against it. The planetary must have a very small amount of up and down play.

Lay the mixer on its side and look up through the base. You willnotice a small set screw. This holds the pin tight. If the set screw gets loose the pin willl begin to move out and the head will wobble. Simply tighten the set screw. I just did this to my Kitchenaid mixer 10 minutes ago and it now works fine.

You can download the manual for your specific model there, and most of them that I saw included at least basic maintenance like oiling and greasing locations. Good luck!

If you can unplug the mixer and test resistance between leads of the selector switch. The resistance should vary from high to low as you move the selector from low to high. If cord and all else looks good and switch is bad replace the switch.
