GENERAL SAFETY RULES
WARNING!
When using an electric chain saw, always follow basic safety precautions to
reduce the risk of fire, electric shock and personal injury.
READ AND SAVE ALL INSTRUCTIONS FOR FUTURE USE. Before use, be sure everyone
using this tool reads and understands this manual as well as any labels packaged with or
attached to the tool.
1. Keep Work Area Clean.
Cluttered areas invite injuries.
Do not start cutting until you have a
clear work area, secure footing, and a
planned retreat path from the falling
tree.
2. Consider Work Area Environment.
Use extreme caution when cutting small
size brush and saplings because the
slender material may catch the saw
chain and be whipped toward you or
pull you off balance.
Do not operate a chain saw in a tree
unless specifically trained to do so.
When cutting a limb that is under ten-
sion be alert for spring back so that
you will not be struck when the tension
in the wood fibers is released.
Do not expose chain saw to rain.
Do not use chain saw in damp or wet
locations.
Do not use chain saw in presence of
flammable liquids or gases.
3. Guard Against Electric Shock.
Prevent body contact with grounded
surfaces such as metal pipes or wire
fences.
4. Keep Children Away.
Do not let visitors contact chain saw or
extension cord.
All visitors should be kept away from
work area.
5. Store Idle Chain Saw.
When not in use, chain saws should
be stored in a dry, and high or locked-
up place, out of the reach of children.
When storing saw, use a scabbard or
carrying case.
6. Dont Force Chain Saw.
It will do the job better and safer at the
rate for which it was intended.
7. Use Right Tool.
Cut wood only.
Do not use chain saw for purpose not
intended, for example, Dont use chain
saw for cutting plastic, masonry, or
non-wood building materials.
8. Dress Properly.
Do not wear loose clothing or jewelry.
They can get caught in moving parts.
Rubber gloves and non-skid footwear
are recommended when working outdoors.
Wear protective hair covering to con-
tain long hair.
9. Use Safety Equipment.
Wear safety glasses, safety footwear,
snug fitting clothing, protective gloves,
hearing protection and head protection.
10. Carry the chain saw by the front
handle with the saw stopped, finger off the switch, the guide bar
and saw chain to the rear.
11. Maintain Chain Saw With Care.
Inspect chain saw cords periodically
and if damaged, have repaired by authorized service facility.
Keep cord clear of the chain and op-
erator at all times.
Never carry saw by the cord or pull it
to disconnect from receptacle.
Keep cord from oil and sharp edges.
Inspect extension cords periodically
and replace if damaged.
Keep tools sharp and clean for better
and safer performance.
Follow instructions for lubricating and
changing accessories.
Keep handles dry, clean, and free from
oil and grease.
12. Disconnect chain saw when not in
use, before servicing, and when
changing accessories and attachments, such as saw chain and
guard.
13. Outdoor Use extension cords.
Use only extension cords intended for
use outdoors and so marked.
14. Stay Alert.
Watch what you are doing.
Use common sense.
Do not operate chain saw when you
are tired.
Keep all parts of the body away from the
saw chain when the motor is operating.
Before you start the saw, make sure the
saw chain is not contacting anything.
15. Check Damaged Parts.
Before further use of the chain saw, a
guard or other part that is damaged
should be carefully checked to determine that it will operate properly and
perform its intended function.
Check for alignment of moving parts,
binding of moving parts, breakage of
parts, mounting, and any other conditions that may affect its operation.
A guard or other part that is damaged
should be properly repaired or replaced
by an authorized service center unless otherwise indicated elsewhere in
this instruction manual.
Have defective switches replaced by
authorized service center.
Do not use chain saw if switch does
not turn it on and off.
Do not operate a chain saw that is dam-
aged, improperly adjusted, or is not
completely and securely assembled. Be
sure that the saw chain stops moving
when the trigger is released.
When servicing use only identical re-
placement parts.
16. Guard Against Kickback.
WARNING: KICKBACK may occur when
the nose or tip of the guide bar touches
an object (Fig. 1), or when the wood
closes in and pinches the saw chain in
the cut (Fig. 2).
Fig. 1
Fig. 2
Tip contact in some cases may cause a
lightning fast reverse reaction, kicking
the guide bar up and back towards the
operator. Pinching the saw chain along
the top of the guide bar may push the
guide bar rapidly back towards the operator. Either of these reactions may
cause you to lose control of the saw
which could result in serious injury to user.
The following precautions should be
followed to minimize kickback:
A. Grip Saw Firmly.
B. Hold the chain saw firmly with both
hands when the motor is running. Use
a firm grip with thumbs and fingers en-
circling the chain saw handles (Fig. 3).
Fig. 3
C. Do not over reach.
D. Keep proper footing and balance at all
times.
E. Do not let the nose of the guide bar
contact a log, branch, ground or other
obstruction.
F. Do not cut above shoulder height.
G. Use devices such as low kickback chain,
guide bar nose guards, chain brakes
and special guide bars that reduce the
risks associated with kickback.
H. Only use replacement guide bars and
chains specified by the manufacturer
or the equivalent.
17. Power Supply
Connect chain saw to correct voltage,
that is, be sure that the voltage sup-
plied is the same as that specified on
the nameplate of the tool.

WARNING!
Improperly connecting the
grounding wire can result in the
risk of electric shock. Check with
a qualified electrician if you are in
doubt as to whether the outlet is
properly grounded. Do not modify
the plug provided with the tool.
12
7
Never remove the grounding
prong from the plug. Do not use
the tool if the cord or plug is damaged. If damaged, have it repaired
by a MILWAUKEE service facility
before use. If the plug will not fit
the outlet, have a proper outlet
installed by a qualified electrician.
Grounded Tools:
Tools with Three Prong Plugs
Tools marked Grounding Required have
a three wire cord and three prong grounding plug. The plug must be connected to a
properly grounded outlet (See Figure A). If
the tool should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away from
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool.
The green wire in the cord must be the
only wire connected to the tool's grounding system and must never be attached to
an electrically live terminal.
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and
ordinances. The plug and outlet should look
like those in Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked Double Insulated do not require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with the
applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code.
Double Insulated tools may be used in either of the 120 volt outlets shown in
Figures B and C.

EXTENSION CORDS
Grounded tools require a three wire extension cord. Double insulated tools can
use either a two or three wire extension
cord. As the distance from the supply outlet increases, you must use a heavier
gauge extension cord. Using extension
cords with inadequately sized wire causes
a serious drop in voltage, resulting in loss
of power and possible tool damage. Refer
to the table shown to determine the required minimum wire size.
The smaller the gauge number of the wire,
the greater the capacity of the cord. For
example, a 14 gauge cord can carry a
higher current than a 16 gauge cord. When
using more than one extension cord to make
up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord
for more than one tool, add the nameplate
amperes and use the sum to determine the
required minimum wire size.
Guidelines for Using Extension Cords
If you are using an extension cord out-
doors, be sure it is marked with the
suffix W-A (W in Canada) to indicate that it is acceptable for outdoor
use.
Be sure your extension cord is prop-
erly wired and in good electrical
condition. Always replace a damaged
extension cord or have it repaired by a
qualified person before using it.
Protect your extension cords from
sharp objects, excessive heat and
damp or wet areas.

accessory other than those specifically recommended for use
with this saw may be hazardous.
Cutting with the chain saw
This chain saw is designed to cut wood
and wood products only. Do not use this
saw to cut wood or wood products if nails,
screws, metal plates, or any other material other than wood is in the material. You
may damage the tool and may cause personal injury.

Tighten retaining nut firmly with the
wrench provided.
4. Run the saw without cutting, unplug
the saw and recheck the tension before use.
NOTE: Too much tension will burn the
guide bar and damage the chain. Too
little tension will allow the chain to leave
the guide bar and may cause personal
injury. A new chain will stretch when
used and will require readjustment later.
Using the chain saw
Always be sure of your footing and hold
the chain saw firmly with both hands while
the motor is running.
Chain oil (Fig. 12)
Fig. 12
A
Proper lubrication prolongs chain and guide
bar life. In warm weather use a SAE-30
weight oil. In colder weather use SAE-20
or SAE-10 weight oil. Use only clean oil to
prevent damage to the automatic oiler. Unscrew the cap (A) and fill oil tank before
use.
Automatic oiler
Catalog number 6215 Chain Saw is
equipped with an automatic oiler. The oiler
is preset at the factory to provide continuous guide bar lubrication while the saw is
running. To check if oiler is working properly, hold the nose of the chain saw about
4" from the log and run the chain saw. If
the oiler is working properly the log should
be spotted with oil.
Chain brake (Fig. 13)
The chain saw is equipped with a brake
that is actuated by the movement of the
hand guard/brake. The movement of the
hand guard/brake opens a spring loaded
switch that interrupts the power and mechanically stops the chain until the hand
guard/brake is returned to the operating
position.
NOTE: Do not attempt to remove the chain
brake from the saw. Using the chain saw
without a chain brake will prohibit the users
ability to stop the chain abruptly and may
increase the risk of personal injury.

Beware of Kickback (Fig. 15 & 16)
"Kickback" is the term used to describe the
sudden, rapid backward and/or upward
motion of the chain and guide bar. Pinch
Kickback (Fig. 15) is the rapid backward
movement of the saw which can occur
when the wood closes in and pinches the
moving saw chain in the cut along the top
of the guide bar. Rotational Kickback
(Fig. 16) is the rapid upward and backward motion of the saw which can occur
when the moving saw chain near the upper portion of the tip of the guide bar contacts an object, such as a log or branch.
Fig. 15
Pinch Kickback
APPLICATIONS

B
10 11
Fig. 16
Reducing the chance kickback
Use recommended guide bar and chain,
others may not reduce kickback.
Make sure chain is sharp and properly
lubricated. Dull, improperly sharpened,
and/or unlubricated chains can cause
kickback.
Allow saw to come to full speed be-
fore applying it to the cut.
Keep saw running when removing it
from the cut.
Reducing the chance of pinch kickback
Always try to cut in a downward motion,
with the bottom side of the chain and guide
bar. This will reduce the chance of kickback in two ways:
If you are cutting downward on
branches or bucked logs , the cut will
tend to open up as you go and reduce
the chance of pinching the chain and
guide bar.
Rotational
Kickback
If the guide bar and chain are pinched
the saw will tend to be pulled into the
wood and not thrown toward you.
Reducing the chance of rotational
kickback
Do not cut with the tip of the guide bar.
Check the work area and avoid acci-
dentally brushing the tip against wood.
Cut one piece of wood at a time and
check to make sure that while cutting
one piece that the nose doesn't accidently come in contact with another
piece of wood or other obstruction.
Preparing for Kickback
The operator should do everything possible to reduce the chance of kickback (see
above). The operator should also do everything possible to be prepared for kickback if it occurs.
Correct grip (Fig. 17)
The correct grip will help the operator keep
control of the saw. Fig. 17 shows the correct grip on the saw with the thumb and
fingers encircling the front handle.
Fig. 17
Body position (Fig. 18)
Plant feet firmly on solid ground.
Hold saw with left arm straight with
elbow locked.
Stand to left side of
cut, out of the kickback path of the
saw.
Cut within a com-
fortable controlled
reaching distance
at chest height or
below.
Fig. 18
Basic cuts
1. Support log in a stable position.
2. Check for adequate clearance for cut.
3. Allow saw to come to full speed before cutting.
Overbucking, or cutting down through
log (Fig. 19)
1. Place lower end of spiked bumper
against the log.
2. Pivot saw into the cut and allow it to cut
its way down.
3. Reposition spiked bumper lower down
and repeat working down the log until
through the cut.
Fig. 19
Underbucking, or cutting up from the
bottom of a log (Fig. 20)
Most cuts should be made according to the
overbucking instructions. But, in some situations, it may be necessary to cut with the
top of the guide bar.
1. Be prepared for a "pushing" action from
the saw. Keep in mind instructions
listed under "preparing for kickback".
2. Allow saw to come to full speed.
3. Lift the saw into the cut in a controlled
motion.
Fig. 20
Felling a Tree
Work area (Fig. 21)
Do not fell trees by roads, power lines,
or buildings without permission from
appropriate authorities. Traffic control
or other preparations may be necessary. If a felled tree contacts a power
line do not go near it. Notify the power
company and provide a warning for
others.
Keep bystanders, coworkers, pets etc.
at a distance at least twice the height
of the tallest tree being felled.
Fig. 21
When bucking and felling operations are
being performed by two or more persons at the same time, the felling operation should be separated from the
bucking operation by a distance of at
least twice the height of the tree being
felled.
Check intended cut area for nails, fence
wire, stones etc. and remove these
materials before cutting.
Retreat path (Fig. 22)
Before beginning to fell a tree, clear
retreat paths (A) at 45º angles to the
line of the fall (B).
Fig. 22
A
B
A
The operator should be on the uphill
side of the terrain when felling a tree.
Toward the end of the cut, be prepared
for the tree to roll or slide down the hill.
The wind speed and direction and the
shape of the tree and its limbs will affect the direction of the fall. If unsure
of any this information, call a professional for help.
Notching (Fig. 23)
1. Make a lower horizontal notching cut
about 1/3 of the way through the tree
(A). This will help to avoid pinching of
the saw chain or guide bar when the
second cut is made.
Fig. 23
2. Make an angled cut to finish the notch
(B).
Felling back cut (Fig. 24 & 25)
1. Make a horizontal felling back cut 2"
above the initial notching cut so that
there will be a 2" "hinge" (A) created in
the tree. Do not cut through the hinge.
The hinge prevents the tree from twisting and falling in the wrong direction
when felled.
Fig. 24
2"
NOTE: When cutting larger diameter
trees, as the felling back cut
progresses, drive nonmetallic (wood
or plastic) wedges into the felling back
cut (B). These wedges help to keep
the felling back cut open and reduce
the risk of the tree "leaning back" onto
the guide bar and chain. Continue to
add wedges as needed until felling back
cut creates the 2" "hinge".
Fig. 25
B.
A.
A
2"
2. Usually the tree will begin to fall as you
complete the felling back cut. However
if it does not, remove the saw and drive
nonmetallic wedges (B) into the felling
back cut until the tree begins to fall.
3. Remove the saw from the cut, stop the
motor and put the saw down. Watch
out for falling limbs and move away
from falling tree following the retreat
path. Watch your footing as you move
away from the tree.
Limbing a tree (Fig. 26)
"Limbing" is removing the branches from a
fallen tree.
1. Cut the smaller upper limbs of the tree
first and let the larger lower limbs hold
the tree off of the ground.
2. Cut limbs under tension in a direction
so that the tension causes the cut to
open up rather than pinch the chain
and guide bar.
Usually this means cut limbs under tension from the bottom (A).
Fig. 26
A
3. Do not remove the larger supporting
limbs until the tree is bucked into shorter
logs. See directions below.
B
12 13
Bucking a log
When bucking a log, (cutting it into lengths)
it is important to make sure your footing is
firm and your weight is evenly distributed.
In general, try to have the log raised and
supported near the cut. Having the log
raised and supported near the cut will reduce binding and kickback.
If bucking log on hill (Fig. 27)
The operator should be on the uphill side
of the cut so when the cut off piece rolls,
it rolls away from the operator. Do not let
the chain come into contact with the
ground. Toward the end of the cut reduce
cutting pressure, maintain firm grip, and be
prepared for log to roll away from the saw
and the operator.
Fig. 27
After completing the cut, wait for the saw
chain to stop before moving the saw. Always stop the motor before continuing to
another tree.
If log supported along entire length
(Fig. 28)
If log supported along entire length, such
as on the ground, cut from the top (A) roll
log over and finish the cut. Rolling the log
over and finishing the cut from the top will
prevent the cutting into the ground where
the dirt and stones will dull the chain.
Fig. 28
A
If log supported on one end (Fig. 29)
If log supported on one end cut 1/3 of the
way through the log from the bottom (A)
and finish the cut from the top (B). Cutting
this way will make the cut off portion fall
away cleanly and easily.
Fig. 29
B
A
If log supported on both ends (Fig. 30)
If log supported on both ends cut 1/3 of the
way through the log from the top (A) and
finish the cut from the bottom (B). Use extra caution to make sure that the chain saw
does not bind up in the cut.
Fig. 30
A
B
MAINTENANCE
Under normal usage, your chain saw will
require regular inspection and maintenance.
Examine the saw for dirt and debris that
might prevent safety and anti-kickback devices from working properly. Inspect the
saw and its safety devices to determine
that it will operate properly. Failure to follow the maintenance procedures indicated
below or the removal of safety devices
may increase the risk of injury.
Cleaning guide bar, chain and chain
brake
Remove the guide bar and chain after each
use or as needed to clean out chips and
debris from the sprocket area. Clean guide
bar groove, soak in light oil and wipe clean.
Clean out chips and debris from the chain
brake after each use or as needed. Check
the brake for normal operation before each
use. See "Cleaning" for further cleaning
instructions.
Sharpening chain (Fig. 31 & 32)
Use a 5/32" diameter round file to sharpen
cutter links (A).
Fig. 31
Fig. B shows the link from the front.
Fig. C shows the link from the top.
Fig. 32
A
A
Setting the Depth (Fig. 33)
The front part (A) of the cutter link is designed to limit the depth of cut of the tooth.
Fig. 33
A
If the tooth is limited too much, the chain
saw will not cut as effectively as it
can.
If the tooth is not limited enough, the
tooth will take too big a bite and contribute to kickback.
File the front of the cutter link so that it is
.025" lower than the cutting tooth.
The Clutch (Fig. 34)
This chain saw is equipped with a disc
clutch designed to protect the motor from
overload. It has been preset at the factory.
The clutch should slip when the saw is
bogged down in a cut. If the clutch slips
during a normal cut, or does not slip when

Replacing the chain
To replace the chain, refer to instructions
under Assembly. Use only Low-Kickback
saw chains that meet the ANSI B175.12000 kickback requirements, other chains
may not reduce kickback. Refer to your
MILWAUKEE catalog for proper replacement parts.

4. Rotate the adjusting bolt flange (A) so
that the mark on the flange (B) lines up
with the next reference mark on the
thrust washer (C).
If the clutch is slipping during a normal
cut, tighten the adjusting bolt flange to
the next mark clockwise (E).
If the clutch is not slipping when it
should, for example when the saw is
bogged down in a cut, loosen the adjusting bolt flange to the next mark counterclockwise (D).
5. Replace the sprocket cover and make
a few test cuts and readjust if necessary.
Tighten the clutch only enough that it
will not slip during a normal cut, but slips
when the saw is bogged down. If repeated slippage occurs after adjusting,
take the chain saw to an authorized
MILWAUKEE repair facility for adjustment or repair.
Inspecting guide bar (Fig. 35)

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, 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 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
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.
