MAINTENANCE

WARNING!

To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disassemble the tool or try to do any rewiring on the tool's electrical system. Contact a MILWAUKEE service facility for ALL repairs.

1.Remove the motor and bit.

2.Tip the Dymorig on its back so that the wheels point down.

3.Remove the old gasket.

4.Squeeze a continuous bead of rubber cement (Cat. No. 44-22-0060) in the entire bottom of the groove.

5.Place the new gasket (Cat. No. 43-44-0605) into the groove making sure it is pushed in completely.

Maintaining Tools

Keep your tool in good repair by adopting a regular maintenance pro- gram. Before use, examine the general 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 mount- ing, broken parts and any other condition that may affect its safe opera- tion. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a dam- aged 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 MILWAUKEE service 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

Lubricating Rack and Pinion

Maintain a light coat of MILWAUKEE Type "E" Grease on the rack and pinion gears to reduce friction and wear.

Lubricating the Spindle for Dymodrills with a Shear Pin

Before each use, clean and lubricate the spindle or spindle sleeve with MILWAUKEE Type "E" Grease to prevent the spindle from seizing during coring.

1.To maintain the spindle on shear pin models, remove the retaining ring with a screwdriver. Then remove the spindle sleeve.

2.Remove dust and debris from the inside and outside diameter of the spindle and spindle sleeve and from the water hole in the spindle. Place a light coating of MILWAUKEE Type "E" grease on the spindle.

3.Replace the spindle sleeve onto the spindle. Make sure the spindle sleeve rotates freely on the spindle. Then replace the retaining ring.

Replacing Vacuum Pad Gaskets

For Cat. No. 4115, 4125 & 4130 only.

Through normal use, the rubber gaskets on the underside of the vacuum pads can become worn, requiring replacement. If replacement is re- quired, take the pad to an authorized service center or replace the gasket as follows:

1.Remove the old gasket and thoroughly remove the old glue from the groove.

2.Squeeze a continuous bead of rubber cement (Cat. No. 44-22-0060) in the entire bottom of the groove.

3.Immediately place a new gasket (Cat. No. 43-44-0570) in the groove and press firmly in place.

4.Turn the pad over and place the gasket side on a smooth flat surface and apply pressure to all edges of the pad.

5.Allow cement to dry for 24 hours before using.

For Cat. No. 4120 only.

With normal use, the rubber gasket on the underside of the base can become worn, requiring replacement. If replacement is required, take the base to an authorized service center or replace the gasket as follows:

6.Stand the Dymorig upright again.

7.Reinstall the motor and bit.

Cleaning the Filter on the Vacuum Pump

Periodically clean the filter felts to keep the vacuum pump operating efficiently. To clean the filter felts, remove the plastic jar and remove the felts from the plastic tube. Remove dust and debris from the felts and clean the plastic jar. Then replace the felts on the plastic tube and posi- tion the jar onto the filter assembly.

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 thinner, 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.
