ACCESSORIES
WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.
WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.
Typical Operation
1.Check the work surface to make sure it is clean and free of foreign materials.
Paint, rust, scale or uneven surfaces decrease the holding strength of the magnet. Chips, burrs, dirt and other foreign materials on the surface of the magnetic base will also decrease holding power. Use a smooth, flat file to keep the magnet clean and free of nicks.
The electromagnetic drill press attaches mag- netically to 3/8" or thicker ferrous stock. Do not use on stock less than 3/8". The magnetic base WILL NOT hold on nonmagnetic grades of stain- less steel.
2.To install/remove cutter:
A.Raise the drill motor to its highest position. Tighten stop knob.
B.Insert cutter into drill spindle with the two (2) flats of the cutter aligned with set screws. Make sure the center pin is inserted into the cutter. NOTE: Cutter should be fully seated into drill spindle.
C.Tighten set screws with 3/16" hex key provided.
D.Loosen the stop knob.
E.Reverse procedure to remove cutter.
NOTE: Do not remove cutter unless slug is removed. Slug may eject unexpectedly. Avoid contact with cutter tips. Periodically inspect the cutter tips for loose or damaged tips.
3.Plug in tool to power source.
WARNING
•Do not use cutting fluid in an overhead or any other position that allows cutting fluid to enter motor or switch enclosure.
•Wet connections are shock hazards. Prevent cutting fluid from traveling along cord and contacting the outlet, extension cord connections or tool plug. Each time tool is plugged in, elevate extension cord or gang
box connections and ar- range a drip loop. If plug or connections get wet, turn power off to outlet before unplugging tool.
4.Move the spindle up so the cutter and center pin are above the work surface.
WARNING To reduce the risk of injury, do not hold workpiece by hand.
5.Position the tool so the center pin is directly over the desired cutting location. Push the magnet switch to the “ON” position. The magnet indicator light will turn on.
WARNING To reduce the risk of injury, always use a safety strap when drilling over- head or on a vertical surface.
6.Useasafetystraponverticaloroverheadsituations.
A.Route the safety strap, ring side first, through the lower slot, and wrap it tightly around a solid, rigid structure as shown. Make sure the strap is not twisted.
B.Hook the safety strap snaphook provided to the ring. Eliminate any slack in the strap.
C.When using on a vertical surface, secure the safety strap with a
NOTE: Do not clamp to the strap. This may damage the strap and cause it to break.

C-clamp
7.With the drill on/off switch in the "OFF" position, fill the cutting fluid reservoir with cutting fluid through the slots in the drill spindle .
Fig. 6
The cutting fluid reservoir will empty as the center pin contacts the work surface. When notching or slotting, it is required to spray cutting fluid directly to the cutter and work piece with the supplied hand pump. Keep hand pump away from moving parts. Failure to use the lubricant properly will cause cutter damage.
The use of HAWG WASH® cutting fluid is recommended for long life of these cutters. The operator is responsible for the application of lu-
not use cutting fluids. Use only lubricant pastes or sprays recommended for high speed cutting. Do not allow lubricant pastes and sprays to enter tool.
8.Start the drill motor by pulling the drill on/off switch to the "ON" position.
WARNING To reduce the risk of injury, always keep hands, rags,
clothing, etc. away from mov- ing parts and chips. Do not try to remove chips while the cutter is rotating. Chips are sharp and can pull objects into moving parts.
9.These units have a 8:1 feed ratio: i.e. for every pound applied to the handle, you create eight pounds on the drill point. Even large bits only re- quire a small amount of pressure on the handle. Example: 20 Pounds on the handle creates 160 Pounds on the drill point.
When feeding the cutter into the material, apply only enough force to produce a curled chip. Ap- plying too little force will result in small broken chips and increased cutting time. Applying too much force will cause overheating of the cutter resulting in short cutter life. Overheating of the cutter can be noticed when cutter and chips turn brown or blue. Excessive force can cause the cutter to slow down to a point where cutting time will increase. The use of cutting lubricants will reduce cutting heat and increase cutter life Use less feed pressure when slotting or notch- ing because there is less support for the cutting edges in these situations.
WARNING Excessive force will break magnet free.
10.Keep constant pressure throughout the entire operation to prevent chips and burrs from falling under the cutting edges. Cutting debris under the cutter can make cutting difficult or impossible.
11.When the cut is complete, withdraw the cutter while the drill spindle is still rotating.
12.Stop the drill motor by pushing in the drill on/ off switch to the "OFF" position.
13.When the drill spindle has stopped rotating, use a pliers to remove cutting debris and chips from the cutter and spindle. Use care to avoid damaging the cutter teeth.
14.If the slug is still present in the cutter, rotate the feed handle to highest position. This will eject the slug from the cutter. The center pin is spring loaded. Provide protection from ejected slug for people and property below cutting area.
15.Make sure you have a firm grip on the tool before turning off the magnet. Push the mag- net switch to the "OFF" position. The magnet indicator light will turn off.

MAINTENANCE
WARNING To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disas- semble the tool or try to do any rewiring on the tool’s electrical system. Contact a MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the gen- eral condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage. Check for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT USE” until repaired (see “Repairs”). Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced. After six months to one year, depending on use, return your tool to the nearest MILWAUKEEservice facility for the following:
•Lubrication
•Brush inspection and replacement
•Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)
•Electrical inspection (switch, cord, armature, etc.)
•Testing to assure proper mechanical and electrical operation
WARNING To reduce the risk of injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to flow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean your tool since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include: gasoline, turpentine, lacquer thin- ner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the nearest service center.
