SOURCE: Hilti TE6A battery dril 36volts,trigger problems

what about the brushes. even if they arent worn completely down they sometimes will not have enough pressure on the commutator tabs to keep the tool running. if it works better upside down or sideways that is often an indication of faulty brushes. the springs that hold the brushes against the commutator may also be weakened to the point that they don't properly force contact. you may also have burned or blank spots on the commutator/armature.

try new brushes and make sure the associated wires arent broken, pinched or otherwise damaged. also clean the commutator with a polishing cloth or very very very fine sandpaper, being careful not to scratch, groove, or otherwise damage the tabs. also, the bearings that fit in the housing to stabilize the armature may be worn or seizing, which will cause the armature to move erratically and/or bind.

if all of these things have been done, and the problem STILL exists, then probably the motor itself (armature/field) is breaking down. the brushes and bearings at least are probably in stock at a local tool repair shop, and of course all parts can be purchased through hilti.

SOURCE: cord got cut on my dewalt screwgun. dont know how

Have you removed the old cord yet, if not make a crib sheet showing where the wires go. If the wires push into the switch use a staple and bend one of the long ends and push into hole and when pushing gently pull the cord wire out. Let me know if you need any other help

I would contact Hilti or a Hilti dealer. Here is a link to their site. You will have to remove any fasteners that hold the housings together so that you can replace the switch.

How to change the tip?

Just pull it out. If it is rusted stuck, get a pair of pliers on there and give it a yank. It will come out.

Bosch sg 45 drywall screw gun

You have to replace the entire depth guage assembly (the front plastic pieces where the bit driver is). Unfortunatly Bosch does not make the individual pieces for this gun. Any Bosch service center will be able to supply you with this piece
