Blades are loose, howndo i tighten them - Casa Vieja Probe White Ceiling Fan

Most have lugs the blade fit in and washer on bolt.

Loosen the knob at the rear of the top arm - turn it counterclockwise several turns. The blade should now be loose. Push the "blade end" of the top arm down slightly with one hand while you unhook the top of the blade. Lower the blade a little to unhook it from the bottom arm.

Replace the blade. Hook it onto the lower arm first - you can look underneath to see what you're doing. The blade's teeth should point DOWNWARD - it's easy to accidentally install it the wrong way, so check that now. Again push down slightly on the end of the upper arm, then hook the top of the blade into the upper arm's blade holder. It should how stay in place, but loosely.

Now return to that tensioning knob at the top rear. Tighten it slowly until the blade is BARELY tight, not loose. Tighten the knob 1/2-turn to one full turn tighter to tension the blade.

check for a spring loaded idler pulley that keeps tension on the belt out of place.

sometimes it is the blade and not the clipper

if the blade is unbalanced it will not stay tight and should be replaced then with a block of wood to hold the blade from turning tighten the replacement blade

could be quite a few things, first try another blade and try and notice which pulley it rools off of first. If the back pulley look for a loose axle. If the front also look for a loose axle, bent housing ( from hitting work) or the shaft that tightens the blade might have a bent tang. If the front seems to be a problem you can loosen the axle and shim the backside, Also look at the condition of the tires for excess wear.

Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

put a little bit off LOC-TITE on screw, worked for me

Usually there is a button to press that locks the shaft arbor and then you use a wrench to tighten OFTEN is a left hand thread!

Check for lock button behind the blade guard toward the motor.
