I can't loosen the the sleeve that holds the bit and therefore I can't change my bits.

Inserting the bit should be the same on all versions of the Makita 3612 router. It does depend on the bit size. Press the shaft lock to keep the shaft from turning. I think the lock is close to the handle on one side of the router when you hold the router with the bit/collet up. For small shaft bits, insert the appropriate collet sleeve into the collet cone. Then insert the bit completely into the sleeve. For larger shaft bits, insert the bit completely into the cone. Use the wrench to tighten the collet nut securely. Unlock the shaft lock. Do not over-tighten or leave the bit loose in the collet cone/sleeve. Over-tightening can break the collet cone. Leaving it loose can result in the bit flying out of the collet cone. Either way, injuries can occur. To remove a bit, loosen the collet nut and then remove the bit (or bit and collet sleeve).

The manual is available on the product page: https://www.makitatools.com/products/details/3612 . The direct link to the manual is https://cdn.makitatools.com/apps/cms/doc/prod/361/df12a409-2bd0-48c3-aa38-d635a480a76e_3612_IM.pdf . See page 8.

I hope this helps.

Hopefully you don't have the wrong shank jammed in this because it can be a costly repair.
- Using a screwdriver, pull off the rubber dust cap #21 at the end of the nose & slide it out of your way.
- The shell #22 will also slide up out of your way
- Using a pick or small screwdriver, remove the snap ring #143 at the end of the nose & slide the 2 metal #144 & 1 rubber washer #31 out of your way
Slide the spacer tube #24 & stop sleeve #25 out of your way
Now you can access the 2 pawls #26 that hold the bit in place - you will have to assess what is jammed from here .
As I said, if you have a spline bit jammed in this SDS nose you may be looking at a whole new barrel because even if you extract the bit most of the time is does damage to the bit sleeve in the barrel.

2. Thanks to Danny Paccho I purchased a wrench to use in removing the sleeve from Geers Plumbing


3. Then , removed the \'87 Price Pfister faucet housing from the basin by disconnecting the 2 pipes under the basin and removing the top basin nut; inserted the wrench into the top, turning counter-clockwise until it locked (er tightened a bit) and hammered it out ,gently?, to not damage the escutcheon threads , or the basin nut.
   

On this particular tool, you can't really tighten the bit in the anvil like a bit in a drill chuck. The bit is free floating but held in place by a small steel ball. The steel ball is held in place by the sleeve that slides up and down to release the ball so the bits can be changed. The sleeve is held down by a spring. Bits falling out can be caused by: Using bits without the groove in the bottom of them for the ball to catch in, dirt in the bottom of the anvil so the bit can't seat properly, the ball is missing or stuck, the spring is broke or binding, or the sleeve is bent or too dirty to slide up and down freely. Use compressed air to clean the anvil well and WD40 to clean and lube it further. If bits still fall out you'll have to take it apart and see if the ball, spring or sleeve need to be replaced.

if this is an SDS try grabbing the bit with some vice grips and jiggling it back and forth. DO Not do this when its plugged in or has a battery hooked up. (your model # did not mach an online search so I don't know what you've got. Also a bit of WD-40 or the like may help loosen it up.

Is it possible to grip each part with a pliers and twist and pull at the same time to release the bit? Let some oil run into the collet before you do this.

I usually switch it into reverse and hold the chuck at the same time. It should loosen and the bit will come out. You can also hold the part next to the chuck and turn the chuck clockwise to loosen the bit. To insert a new bit, just do it the opposite way.

I'm sorry but I can't send a diagram via this site. I have no idea where I can get a diagram either.

But, to replace the throttle grip on your Softail, you'll see the not only are you replacing but you're replacing the throttle sleeve as well. This actually makes it easier.

To replace the grip, first loosen the throttle and idle cables as loose as you can at the adjusters close to the throttle grip. Then remove the screws that hold the two halves of the throttle switch housings together. Carefully seperate the housing halves as much as the wires will allow.

You'll see the cables coming up and connecting to the throttle sleeve. Each cable will have a ball and a ferrell on it. Work both cables loose and slide the throttle sleeve off the handlebar.

Now, lubricate the inside of the new throttle sleeve, the cable area of the throttle sleeve and the handlebar with fresh white lithium grease. Slide the throttle sleeve up on the handlebar and work the cables back into the throttle sleeve. Be careful not to lose the ferrells. They must be in there for the throttle to work properly.

Once you get the cables installed into the sleeve, put the switch housings together and install the bolts. Before tighten the bolts slide the throttle up onto the handlebar until it stops. Then back if off about 1/8 to 1/4" or so. Tighten the bolts. Readjust the cables leaving just a bit of slack in the throttle cable.

With the engine off, twist the throttle to wide open throttle and let go of the throttle grip. The throttle should snap shut. If not, loosen the cables a bit or back the throttle grip a bit further off the handlebars. The throttle grip must work correctly or serious injury or death may result. This job must be done correctly. It's not difficult just make sure it's right.

Good luck

My husband explained this, via phone ..... made it simple....... grab the silver ring area beneath the black top area where the drill bit is located. Hold the silver area firmly, while you twist the black top. You will see the release, then remove drill bit. Laymen's terms, but it worked!!

hi this should be reletively easy hold the end black bit with the sivler bit holde coming out not the black bit next to the yellow case on drill you hold the black part thats at end of drill by where the bit goes into not the black bit near the trigger hope i explain this ok.
Hold this bit tight then put drill in reverse then press trigger a couple of times it might be tight but shouldnt be that tight it wont undo.
1 put in reverse
2 hold black plastic piece near where drill bit goes into
3 press trigger few times
4 this should undo it allowing you to put a bit in
make sure its in reverse else you will just tighten it up more let me know if you need further assistance ok
