WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Installing Collets
MILWAUKEE Die Grinders feature a special collet
and collet nut. The collet must be attached to the
collet nut before installing the collet asembly to the
tool. Be sure that the collet size matches the size of
the mounted wheel mandrel you will use, otherwise
the collet may break.
1. To assemble, place collet on an even surface,
take nut and place over collet (Fig. 1).
Fig. 1
2. Position nut squarely over collet (Fig. 2).
Fig. 2
3. Snap nut and collet together by fi rmly applying
downward pressure onto assembly with the palm
of hand (Fig. 3).

WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
ASSEMBLY
4. To disassemble collet from nut, hold nut fi rmly
with one hand and press the collet to one side
with the other hand (Fig. 4).

Collet
Mandrel
Insert mandrel a minimum
Overhang
of 3/4" inside the collet
about 1/2"
1. Remove dust and debris from the collet body
before inserting grinding points.
2. Insert the collet with the collet nut attached into
the collet body. Thread the collet nut onto the
spindle but do not tighten it yet.
3. Clean the grinding point mandrel, then insert it a
minimum of 3/4" into the collet. The mandrel will
overhang the collet and the grinding point about 1/2".
4. Hold the spindle shaft steady with a 1/2" open
end wrench and securely tighten the collet nut
with an 11/16" open end wrench.
5. Reverse the procedure when removing the grind-
ing point.
WARNING
To reduce the risk of in-
jury, always securely tighten the collet to the
grinders and clean mandrels before inserting
them into the collet. Otherwise the high-speed
rotation of the tool could force the grinding
point to fl y out of the collet.
OPERATION
WARNING
If the grinder begins vibrat-
ing, immediately stop the motor and check to
see if the grinding point is dull. Dull grinding
points will cause the tool to vibrate and could
force the collet to fl y off the tool. Always re-
place or sharpen dull grinding points.
Grinding
Always hold the grinder fi rmly before starting the
motor. To start the motor for Cat. No. 5192, turn the
toggle switch ON. To start Cat. No. 5194, press the
paddle switch. For Cat. No. 5196, pull the trigger.

Using the Trigger Lock Mechanism (Cat. No.
5196)
The lock button holds the trigger in the ON position
for continuous full speed use.
1. To lock the trigger, hold the lock button in while
pulling the trigger, then release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock button will pop out.
Allow the motor to reach full speed and then place
the grinding point on the work surface. The tool is
designed to work most effi ciently with only light
pressure. Excessive pressure will burn the work
surface, damage the grinding point, bend the
mandrel, and cause slow grinding.
When a grinding point becomes dull, the grinder
may start to vibrate. When this happens immedi-
ately stop using the grinding point. Vibration could
loosen the collet, causing the grinding point to fl y
off the tool. Replace a dull grinding point with a new
one or use a dressing stone to sharpen the dull
point. Handle grinding points carefully. Dropping
them or dropping the grinder could cause the point
to shatter. Do not operate the grinder carelessly
because it may cause the grinding point to explode
at high speeds.
ACCESSORIES
WARNING
To reduce the risk of injury,
always unplug the tool before attaching or
removing accessories. Use only specifi cally
recommended accessories. Others may be
hazardous.
For a complete listing of accessories refer to your
MILWAUKEE Electric Tool catalog or go on-line
to www.milwaukeetool.com. To obtain a catalog,
contact your local distributor or a service center.
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.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. 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 mounting, bro-
ken 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 neces-
sary 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, spin-
dles, 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 fl ow 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 fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
