How should a bit be installed in the 2904-20 keyless chuck?
Remove the battery before changing bits. For a drill bit, center it in the chuck jaws and lift it about 1/16 inch from the bottom; for a driver bit, let the jaws grip the hex section. Turn the sleeve clockwise until the chuck ratchets and cannot turn farther. The manual says that ratcheting during opening or closing is part of the lock and is not a fault.
How do I enable, disable, or check AutoStop on the 2904-20?
The drill ships with AutoStop enabled. To change its state, put the control switch in the center lock position and pull the trigger five times: the light dims out when disabled and flashes when enabled. The manual also says the chosen state persists across battery changes and describes a hand-rotation check in which an enabled tool flashes and shuts off.
How should the side handle be fitted and used?
Milwaukee directs users to use the side handle, brace the tool securely, and confirm that the handle is tight before each use. The handle hooks fit the slots on the gearcase ring; it may be positioned on top and point left or right, then tightened securely. Remove the battery before fitting or repositioning it.
What drilling and driving capacities does Milwaukee specify for the 2904-20?
The operator's manual rates the 2904-20 for up to 1/2-inch steel, 1-1/2-inch flat or auger bits in wood, a 3-1/2-inch hole saw, 5/8-inch screws, a 2-9/16-inch self-feed bit, and 5/8-inch masonry. These are manufacturer-listed application capacities, not a substitute for using a bit rated for the material and speed.
What routine cleaning and inspection does the 2904-20 require?
Keep the vents clear and the tool dry and free of oil or grease; use mild soap and a damp cloth rather than gasoline, paint thinner, chlorinated solvents, ammonia, or similar cleaners. Milwaukee also calls for regular inspection for abnormal noise, binding, misalignment, or broken parts, with service-center inspection after roughly six months to one year depending on use.
Are major wear or drive components listed as service parts for the 2904-20?
Yes. Milwaukee's exact 2904-20 service-parts bulletin lists a 1/2-inch keyless chuck, a chuck screw, a gearbox service assembly, an electronic service assembly, a rotor service assembly, a side-handle assembly, and a belt-clip kit. The operator's manual nevertheless directs users not to disassemble the tool and to use a Milwaukee service facility for repairs.
