Question and Answers

Q:

I just purchased a new house. The sellers did not leave the code for the keypad, how do I reset?

A:

Thank you for your question on the resetting of the key less entry code.

You will have to rest the memory of the door opener.

You will need a ladder for getting up to the motor unit on the opener.

Push and hold the learn button on the motor unit next to the little yellow l.e.d. for at least 6 seconds or until the little l.e.d. light goes out.

Then push but do not hold the learn button and put in you new 4 digit number on the number pad and push and hold the enter button for a few seconds until the work light on the motor unit flashes once. You will have about 30 seconds to do the programming before it times out.

Then push the learn button so the light comes on and program your remotes. Again with each remote the work light should flash once.

This process should program all your remotes and key less entry pad.

Charis, I recommend clearing all the codes as stated above. Then program the remote that is not working first. If it will not program but all the others do, I suspect a problem with that remote. You can try swapping out the battery from another remote first. If that remote this will not work, I recommend replacing the remote. Please let me know what happens, after trying this. Thank you for using Manage my life. Mark.

Q:

McCulloch MAC 160S Chainsaw

A:

Thank you for your question.

 

I am sorry you are having a problem with the chain saw. If the chain will not tighten when you loosen the nuts and turn the adjusting screw, I suspect the adjustment pin on the clutch cover is broken or not positioned in the bar. I found a video that shows how to replace the adjustment pin. The video also shows how the pin should fit into the bar. Click here to watch the video. 

 

I hope this is helpful. Please let me know if you need further assistance.

Q:

McCulloch Mac 2816 weed wacker

A:

Thank you for your question.

I am sorry you are having a problem with the trimmer. If you have installed a module and still do not have spark I recommend removing the kill wire and check for spark with a new plug. If you still do not have spark double check the air gap between the module and the magnet on the flywheel. The air gap should be set between .010 to .012. Then check for spark. If there still is no spark, the problem is either a weak flywheel magnet or defective module. If the magnet holds a screwdriver, it should be fine.

I hope this is helpful. Please let me know if you need further assistance.

Thank you for using Manage my life.

Thank you for the reply. If the kill wire is removed from the module, when you are checking for spark it will not matter if it is frayed. You can repair the wire later once you have spark. If the magnet is fine and the air gap is set, you should have spark. If you do not have spark I suspect a defective module. I know it is not likely but everything else is fine. Just make sure you are using a know good plug and it is grounded to a clean ground when checking for spark. I hope this is helpful.

A:

By what you have stated you have done, I suspect the module is defective. If you happen to have the old module, you might want to install it and check for spark with the kill wire disconnected. If you have spark, repair the kill wire. If you do not have spark I recommend replacing the module.

A:

The coil has to be having a good connection to the engine block. This is important for the module to generate the spark. By everything you done so far, I suspect the problem is a defective module. I know it seems unlikely but the checks done point to the module.

A:

We are missing something somewhere. Try to set the air gap at .012. While tightening the screws, make sure the module does not turn away from the flywheel. Then check for spark with out the spark plug. To do this, insert a screwdriver where the spark plug would go. Then hold the shank of the screwdriver about a 1/8 inch or so from the block. While holding the screwdriver in this position, turn the engine over. You should see a spark jump from the shank to the block. If you get spark the plug is causing the problem. Please let me know what you find.
