WARNING!
The vibration emission level given in this information sheet has been measured
in accordance with a standardized test given in EN 60745 and may be used to
compare one tool with another. It may be used for a preliminary assessment of
exposure. The declared vibration emission level represents the main
applications of the product. However, if the product is used for different
applications, with different accessories, or is poorly maintained, the
vibration emission may differ. This may significantly increase the exposure
level over the total working period.
An estimation of the level of exposure to vibration should also take into
account the times when the product is switched off or when it is running but
not actually doing the job. This may significantly reduce the exposure level
over the total working period.
Identify additional safety measures, such as maintaining the product and the
accessories, keeping the hands warm, and organizing work patterns, to protect
the operator from the effects of vibration.
WARNING!
Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire, and/or serious injury.
Save all warnings and instructions for future reference.
SAFETY INSTRUCTIONS FOR MANUAL CIRCULAR SAWS
Cutting procedures
a) DANGER: Keep hands away from the cutting area and the blade. Keep your
second hand on the auxiliary handle, or motor housing. If both hands are
holding the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard cannot protect you from
the blade below the workpiece.
c) Adjust the cutting depth to the thickness of the workpiece. Less than a
full tooth of the blade teeth should be visible below the workpiece.
d) Never hold pieces being cut in your hands or across your leg. Secure the
workpiece to a stable platform. It is important to support the work properly
to minimize body exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping surfaces only, when performing an
operation where the cutting tool may contact hidden wiring. Contact with a
“live” wire will also make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
f) When ripping, always use a rip fence or straight-edge guide. This improves
the accuracy of the cut and reduces the chance of blade binding.
g) Always use blades with the correct size and shape (diamond versus round) of
arbor holes. Blades that do not match the mounting hardware of the saw will
run eccentrically, causing a loss of control.
h) Never use damaged or incorrect blade washers or bolts. The blade washers
and bolts were specially designed for your saw, for optimum performance and
safety of operation.
Kickback causes and related warnings:
– kickback is a sudden reaction to a pinched, bound, or misaligned saw blade,
causing an uncontrolled saw to lift up and out of the workpiece toward the
operator;
– when the blade is pinched or bound tightly by the kerf closing down, the
blade stalls, and the motor reaction drives the unit rapidly back toward the
operator;
– if the blade becomes twisted or misaligned in the cut, the teeth at the back
edge of the blade can dig into the top surface of the wood causing the blade
to climb out of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw and position your arms to
resist kickback forces. Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the saw to jump backward, but
kickback forces can be controlled by the operator, if proper precautions are
taken.
b) When the blade is binding, or when interrupting a cut for any reason,
release the trigger and hold the saw motionless in the material until the
blade comes to a complete stop. Never attempt to remove the saw from the work
or pull the saw backward while the blade is in motion or kickback may occur.
Investigate and take corrective actions to eliminate the cause of blade
binding.
c) When restarting a saw in the workpiece, center the saw blade in the kerf
and check those saw teeth are not engaged in the material. If the saw blade is
binding, it may walk up or kick back from the workpiece as the saw is
restarted.
d) Support large panels to minimize the risk of blade pinching and kickback.
Large panels tend to sag under their own weight. Supports must be placed under
the panel on both sides, near the line of cut, and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened or improperly set blades
produce narrow kerfs causing excessive friction, blade binding, and kickback.
f) Blade depth and bevel adjusting locking levers must be tight and secure
before making a cut. If blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing walls or other blind areas. The
protruding blade may cut objects that can cause kickback.
Lower guard function
a) Check the lower guard for proper closing before each use. Do not operate
the saw if the lower guard does not move freely and close instantly. Never
clamp or tie the lower guard into the open position. If the saw is
accidentally dropped, the lower guard may be bent. Raise the lower guard with
the retracting handle and make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of the cut.
b) Check the operation of the lower guard spring. If the guard and the spring
are not operating properly, they must be serviced before use. The lower guard
may operate sluggishly due to damaged parts, gummy deposits, or a build-up of
debris.
c) Lower guard may be retracted manually only for special cuts such as “plunge
cuts” and “compound cuts”. Raise the lower guard by retracting the handle and
as soon as the blade enters the material, the lower guard must be released.
For all other sawing, the lower guard should operate automatically.
d) Always observe that the lower guard is covering the blade before placing
the saw down on a bench or floor. An unprotected, coasting blade will cause
the saw to walk backward, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after the switch is released.
Additional Safety and Working Instructions:
Wear ear protectors. Exposure to noise can cause hearing loss.
Use protective equipment. Always wear safety glasses when working with the
machine.
The use of protective clothing is recommended, such as a dust mask, protective
gloves, sturdy non-slip footwear, helmet, and ear defenders. The dust produced
when using this tool may be harmful to health. Do not inhale the dust. Use a
dust absorption system and wear a suitable dust protection mask. Remove
deposited dust thoroughly, e.g. with a vacuum cleaner.
Do not use saw blades not corresponding to the key data given in these
instructions for use.
Do not fix the on/off switch in the „on“ position when using the saw hand-
held.
Please do not use abrasion disks in this machine! Adapt the feed speed to
avoid overheating the blade tips and to avoid melting plastic materials during
cutting.

SPECIFIED CONDITIONS OF USE
This electronic circular saw can cut lengthways and miter accurately in wood.
Do not use this product in any way other than those stated in the intended
use.
ELECTRIC BRAKE
The electric brake engages when the trigger is released, causing the blade to
stop and allowing you to proceed with your work. Generally, the saw blade
stops within two seconds. However, there may be a delay between the time you
release the trigger and when the brake engages.
Occasionally the brake may miss completely. If the brake miss frequently, the
saw needs servicing by an authorized Milwaukee service facility. You must
always wait for the blade to stop completely before removing the saw from the
workpiece.
BATTERIES
Battery packs that have not been used for some time should be recharged before
use.
Temperatures in excess of 50°C (122°F) reduce the performance of the battery
pack. Avoid extended exposure to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum lifetime, the battery packs have to be fully charged, after
use.
To obtain the longest possible battery life remove the battery pack from the
charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C and away from
moisture. Store the battery packs in a 30% – 50% charged condition. Every six
months of storage, charge the pack as normal. Do not dispose of used battery
packs in the household refuse or by burning them. Milwaukee Distributors off
er to retrieve old batteries to protect our environment. Do not store the
battery pack together with metal objects (short circuit risk). Use only System
C12 chargers for charging System C12 battery packs. Do not use battery packs
from other systems.
Never break open battery packs and chargers and store only in dry rooms. Keep
dry at all times.
Battery acid may leak from damaged batteries under extreme load or extreme
temperatures. In case of contact with the battery, acid washes it off
immediately with soap and water. In case of eye contact rinse thoroughly for
at least 10 minutes and immediately seek medical attention.
No metal parts must be allowed to enter the battery section of the charger
(short circuit risk).
BATTERY PACK PROTECTION
In extremely high torque, binding, stalling, and short circuit situations that
cause a high current draw, the tool will stop for about 2 seconds, and then
the tool will turn OFF. To
reset, release the trigger. Under extreme circumstances, the internal
temperature of the battery could become too high. If this happens, the battery
will shut down. Place the battery on the charger to charge and reset it.
MAINTENANCE
Be sure to disconnect the tool from the power supply before attaching or
removing the saw blade.
Clean the tool and guarding system with a dry cloth. Certain cleaning agents
and solvents are harmful to plastics and other insulated parts.
