SPECIFIED CONDITIONS OF USE
This electronic circular saw can cut lengthways and mitre accurately in
wood, plastic, and aluminium.
Do not use this product in any other way as stated for normal 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 misses frequently, the saw
needs servicing by an authorized service facility.
You must always wait for the blade to stop completely before removing the
saw from the workpiece.

BATTERIES
New battery packs reach full loading capacity after 4 - 5 chargings and
dischargings. Battery packs which 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 life-time, the battery packs have to be fully charged, after
used.
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.
BATTERY PACK PROTECTION
In extremely high torque, binding, stalling and short circuit situations that
cause high current draw, the tool will vibrate for about 2 seconds and then
the tool will turn OFF.
To reset, release the trigger.
Under extreme circumstances, the internal temperatur of the battery could
become to high. If this happens, the battery will shut down.
Place the battery on the charger to charge and reset it.
BATTERY PACK PROTECTION LI-ION BATTERY
The battery pack has overload protection that protects it from being
overloaded and helps to ensure long life.
Under extreme stress the battery electronics switch off the machine
automatically. To restart, switch the machine off and then on again. If the
machine does not start up again, the battery pack may have discharged
completely. In this case it must be recharged in the battery charger.

SAFETY INSTRUCTIONS
Cutting procederes
Danger: Keep hands away from cutting area and the blade. Keep
your second hand on auxiliary handle, or motor housing. If both hands
are holding the saw, they cannot be cut by the blade.
Do not reach underneath the workpiece. The guard cannot protect you
from the blade below the workpiece.
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.
Never hold piece 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.
Hold the power tool by insulated gripping surfaces, only when
performing an operation where the cutting tool may contact hidden
wiring. Cutting accessory contacting a „live“ wire may make exposed metal
parts of the power tool „live“ and could give the operator an electric shock.
When ripping always use a rip fence or straight edge guide. This
improves the accuracy of cut and reduces the chance of blade binding.
Always use blades with correct size and shape (diamond versus
round) of arbour holes. Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of control.
Never use damaged or incorrect blade washers or bolt. The blade
washers and bolt 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.
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 backwards, but kickback forces can be controlled by the operator, if
proper precautions are taken.
When 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.
When restarting a saw in the workpiece, centre the saw blade in the
kerf and check that saw teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from the workpiece as the saw
is restarted.
Support large panels to minimise 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.
Do not use dull or damaged blades. Unsharpened or improperly set
blades produce narrow kerf causing excessive friction, blade binding and
kickback.
Blade depth and bevel adjusting locking levers must be tight and
secure before making cut.
If blade adjustment shifts while cutting, it may
cause binding and kickback.
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
Check lower guard for proper closing before each use. Do not operate
the saw if lower guard does not move freely and close instantly. Never
clamp or tie the lower guard into the open position. If saw is
accidentally dropped, 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 cut.
Check the operation of the lower guard spring. If the guard and the
spring are not operating properly, they must be serviced before use.
Lower guard may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
Lower guard function
Lower guard may be retracted manually only for special cuts such as
“plunge cuts” and “compound cuts.” Raise lower guard by retracting
handle and as soon as blade enters the material, the lower guard
must be released. For all other sawing, the lower guard should operate
automatically.
Always observe that the lower guard is covering the blade before
placing saw down on bench or floor.
An unprotected, coasting blade will
cause the saw to walk backwards, cutting whatever is in its path. Be aware
of the time it takes for the blade to stop after switch is released.
WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised 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 tool. However if the tool is used for different applications, with different
accessories or 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 tool 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 to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm,
organisation of work patterns.
