GENERAL PRUNING SAW SAFETY WARNINGS
a) Keep all parts of the body away from the saw chain when
the pruning saw is operating. Before you start the pruning saw,
make sure the saw chain is not contacting anything. A m om ent
of inattention while operating pruning saws m ay cause entanglem ent
of y our clothing or bod y with the saw chain.

e) Do not operate a pruning saw in a tree, on a ladder, from a
rooftop, or any unstable support. Operation of a pruning saw in
this m anner could result in serious personal injury .
f) Always keep proper footing and operate the pruning saw
only when standing on xed, secure and level surface. S lippery
or unstable surf aces m ay cause a loss of balance or control of the
pruning saw.
g) When cutting a limb that is under tension, be alert for spring

y ou or pull y ou of f balance.
i) Carry the pruning saw by the front handle with the pruning
saw switched off and away from your body. When transporting
or storing the pruning saw, always t the guide bar cover.
P roper hand ling of the pruning saw will red uce the likelihood of
accid ental contact with the m oving saw chain.
j) Follow instructions for lubricating, chain tensioning and
changing the bar and chain. Im properly tensioned or lubricated
chain m ay either break or increase the chance f or kickback.
k) Keep handles dry, clean, and free from oil and grease.
G reasy , oily hand les are slippery causing loss of control.
l) Cut wood only. Do not use pruning saw for purposes not
intended. For example: do not use pruning saw for cutting
metal, plastic, masonry or non-wood building materials. U se of
the pruning saw f or operations d if f erent than intend ed could result in
a hazard ous situation.
Follow all instructions when clearing jammed material, storing
or servicing the pruning saw. Make sure the switch is off and
the battery pack is removed. U nex pected actuation of the pruning
saw while clearing jam m ed m aterial or servicing m ay result in
serious personal injury .
Causes and operator prevention of kickback:
K ickback m ay occur when the nose or tip of the guid e bar touches
an object, or when the wood closes in and pinches the saw chain
in the cut.
T ip contact in som e cases m ay cause a sud d en reverse reaction,
kicking the guid e bar up and back toward s the operator.
P inching the saw chain along the top of the guid e bar m ay push the
guid e bar rapid ly back toward s the operator.
E ither of these reactions m ay cause y ou to lose control of the saw
which could result in serious personal injury . D o not rely ex clusively
upon the saf ety d evices built into y our saw.

As a pruning saw user, y ou should take several steps to keep y our
cutting jobs f ree f rom accid ent or injury .
K ickback is the result of pruning saw m isuse and / or incorrect
operating proced ures or cond itions and can be avoid ed by taking
proper precautions as given below:
a) Maintain a rm grip, with thumbs and ngers encircling
the pruning saw handles, with both hands on the saw and
position your body and arm to allow you to resist kickback
forces. K ickback f orces can be controlled by the operator, if proper
precautions are taken. D o not let go of the pruning saw.
b) Do not overreach and do not cut above shoulder height. T his
helps prevent unintend ed tip contact and enables better control of
the pruning saw in unex pected situations.
c) Only use replacement guide bars and chains specied by the
manufacturer. Incorrect replacem ent guid e bars and chains m ay
cause chain breakage and / or kickback.
d) Follow the manufacturer’s sharpening and maintenance
instructions for the saw chain. D ecreasing the d epth gauge height
can lead to increased kickback.

Saw jammed in the cut
S top the pruning saw and m ake it saf e. D o not try to f orce the chain
and bar out of the cut as this is likely to break the chain, which m ay
swing back and strike the operator. T his situation norm ally occurs
because the wood is incorrectly supported which f orces the cut to

WARNING!
Consequences of improper maintenance, removal or
modication of safety features, ignition switch, hand guard
(front and back), spiked bumper, chain catcher, guide bar,
low kick-back saw chain may cause the safety features to not
function correctly, thus increasing the potential for serious
injury.
Spiked Bumper
T he integral bum per spike m ay be used as a pivot when m aking
a cut. It helps to keep the bod y of the pruning saw stead y while
cutting. W hen cutting, push the m achine f orward until the spikes
d ig into the ed ge of the wood , then by m oving the rear hand le up or
d own in the d irection of the cutting line it can help ease the phy sical
strain of cutting.
Guide Bar
G enerally , guid e bars with sm all rad ius tips have som ewhat lower
potential f or kick-back. Y ou should use a guid e bar and m atching
chain which is just long enough f or the job. L onger bars increase
the risk of loss of control d uring sawing. R egularly check the chain
tension. W hen cutting sm aller branches ( less than the f ull length of
the guid e bar) the chain is m ore likely to be thrown of f if the tension
is not correct.

•Dress Properly - Wear snug tting clothing. Always
wear heavy, long pants, long sleeves, overalls, jeans
or chaps made of cut resistant material or ones that
contain cut resistant inserts. Wear non-slip safety
footwear. Wear non-slip heavy duty gloves to improve
your grip and to protect your hands. Do not wear
jewelry, short pants, sandals, or go barefoot. Do not
wear loose tting clothing, which could be drawn into
the motor or catch the chain or underbrush. Secure
hair so it is above shoulder level. Wear hearing and
head protection.
•Heavy protective clothing may increase operator
fatigue, which could lead to heat stroke. During
weather that is hot and humid, heavy work should be
scheduled for early morning or late afternoon hours
when temperatures are cooler.
•Always wear eye protection with side shields, as
well as head and hearing protection when operat-
ing this equipment.
•Always be aware of what you are doing when using
the chain saw. Use common sense. Do not oper-
ate the chain saw when you are tired, ill, or under the
inuence of alcohol, drugs, or medication.
•Keep all parts of your body away from the saw
chain when the unit is running.
•Never let anyone use your chain saw who has not
received adequate instructions in its proper use.
This applies to rentals as well as privately owned saws.
•Before you start the unit, make sure the saw chain
is not contacting any object.
•Stop the chain saw before setting it down.
•Maintain the unit with care. Keep the cutting edge
sharp and clean for best performance and to reduce
the risk of injury. Follow instructions for lubricating and
changing accessories.
•Do not operate a chain saw with one hand! Use a
rm grip with thumbs and ngers encircling the chain
saw handles. Serious injury to the operator, helpers,
bystanders, or any combination of these persons
may result from one-handed operation. A chain saw
is intended for two-handed use.
•Do not operate a chain saw that is damaged, im-
properly adjusted, or not completely and securely
assembled. Chain should slow to a stop when the
switch trigger is released. If the chain continues to turn
after the switch trigger has been released, have the
unit serviced by an authorized service center.
•Always maintain a proper stance.
•Do not adapt your powerhead to a bow guide or
use it to power any attachments or devices not
listed for the saw.
•Do not cut vines and/or small underbrush.
•Do not operate a chain saw in a tree, on a ladder,
rooftop, sca󰀨old, or other unstable support; this
is extremely dangerous.
NOTE: The size of the work area depends on the job
being performed as well as the size tree or work piece
involved. For example, felling a tree requires a larger
work area than making bucking cuts.
•Do not force the chain saw. The job can be per-
formed better and safer at the rate for which it was
intended.
•Always use the right product for your application.
The chain saw should be used for cutting wood only.
Never use the chain saw to cut plastic, masonry or
non-wood building materials.
•Store chain saw when not in use. Chain saw should
be stored in a dry and high or locked area out of the
reach of children. When storing chain saw place the
cover on the bar and chain and store the chain saw
in carrying case.
•Battery operated units do not have to be plugged
into an electrical outlet; therefore, they are always
in operating condition. Be aware of possible hazards
even when unit is not operating.
•Save these instructions. Refer to them frequently
and use them to instruct others who may use this
product. If you loan someone this product, loan them
these instructions also.
•After each use, clean the machine with a soft dry
cloth. Remove any chips, dirt and debris in the
battery bay.
•Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
•
WARNING
To reduce the risk of injury, when
working in dusty situations, wear
appropriate respiratory protection or use an
OSHA compliant dust extraction solution.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
•
WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
•lead from lead-based paint
•crystalline silica from bricks and cement and other
masonry products, and
•arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
lter out microscopic particles.
