My Dewalt DW718 miter saw stopped running. Then, after troubleshooting, it came on although it ran erratically. I could see some sparking just under the motor endcap. (Also, the brake has been not been working well lately.)
I took it apart to see if there are any electrical connections in that area. There are not- only the brushes.
You can adjust the tension of the bevel adjustment from slipping by removing the 330045-13 which holds the 618236-00 handle on top of the housing. Then
adjust the handle back until you can lock it and the bevel you have set does not slip. If you have any other questions please let us know.
Take the screw and washer out of the end of the shaft.Heat the pulley with moderate amount of heat or enough to soften up the loctite on the shaft. Put the screw 3/4 of the way back into the shaft and with a pair of gloves and a mallet tap on the screw and pull on the pulley and generally that will allow the pulley to come off. Hope that helps.Good luck.
Dewalt doesn't offer a complete motor assembly as a whole unit, but you can purchase the parts separately, such as the armature,field,brushes etc. Make sure you get the correct type number off of the saw when ordering parts for your saw. This will ensure that you will receive the right parts for your saw.
I need to remove the pin holding the Locking Lever (DW718-Page B-Part #117). Which direction do I drive the pin to remove it? Is the end with the "teeth" on the right or on the left when you stand in front of the saw?
Hi, I have a DW718 miter saw that is unwell! When I pull the trigger, the blade spins as if the belt was slipping, but I've checked the belt & it's good & the tension is fine. Does anybody have any suggestions on what the problem could be???
Thanks for your time!
Hi I have a dewalt dw 718 mitre saw that is faulty. the saw starts in gears 1 to 3 runs for a short time then cuts out at the 110 transformer box . it will not start at all in gears 4 and 5.any ideas on what the problem is would be most appreciated thank you
I am not sure if I understand your gear problem or the transformer..do you have the Dewalt saw connected to a special application of some sort..what you are describing doesn't match up to a condition a DW718 might have..:confused:
do you have any more info?

the transformer is a 110 single socket and works fine with other tools. the saw is quite a new saw so i doubt if it is down to wear and tare. the saw seems to struggle for power in the lower settings before going off but is tripping the transformer box when it does go off. i have checked for obvious loose connections etc but nothing sticks out

The saw does draw a lot of amperage upon start up [about 25 amps and then a steady draw of around 10 to 15..give or take] this may have an negative effect on the transformer..also most house or shop outlets have 115 to 120 volts on average [if the saw has inadequate voltage supply over time the windings may have been damaged ] you may want to try and operate the saw out of a regular outlet to see if it still has issues..also check to see if anything else is running on the transformer box that may cause an overload..
Are the lower settings on the box for different speeds..? This will be problematic for a higher amperage tool..:(
hope this is helpful..?
I have a Mitre saw with blade wobble due to the inner retainer and the gear wear. They both have grooves and I believe they need to be changed.
Would anyone know how to seperate the gear from the gear plate? Not sure of exact names of gear etc.
Any help would be very much appreciated!
Usually the blade wobble is isolated to the inner bushing [it will wear a groove in it] # 26..part # 644999-00 and sometimes the shoulder on the spindle will round off..#28 part # 393702-00
Most of the time replacing the inner bushing will solve the problem [try that first :)]
Gear wear will just be noisy on start up and running and shouldn't effect blade wobble..
The plate can be carefully removed with a screwdriver blade prying..[the spindle and gear are one assembly.].

It doesn't look possible because of the front motor mount plate.it may be a different configuration..also probably not economical..
Best on this one to just repair or replace the parts that you need for the dw708..:)
