7. Adjusting the glass guard
Move the glass guard: top position for diagonal cuts,
central position for 0° cuts, bottom position when a guide
rail is used.
OPERATION
WARNING
○ Pull out the battery after completing operation.
○ Never touch the moving parts.
○ Do not fi x and secure the lock-off button. Besides, keep
your fi nger off the trigger switch when the power tool is
being carried around. Otherwise, the main body switch
can be inadvertently turned ON, resulting in unexpected
accidents.
○ Do not use any abrasive wheels.
○ Use only blade diameter specifi ed on the product
nameplate.
○ Should the saw blade be stopped or make an abnormal
noise during operation, turn off the switch immediately.
CAUTION
○ To extend the lifetime, the lithium-ion battery equips with
the protection function to stop the output. Therefore, if
the tool is overloaded, the motor may stop. However,
this is not the trouble but the result of protection function.
In this case, release the switch of tool and eliminate the
causes of overloading.
○ Take care not to lock the motor. If the motor is locked,
immediately turn the power off . If the motor is locked for
a while, the motor or battery may be burnt.
○ Before use, check to see if the lock-off button moves
smoothly.
1. Check if saw blade is tightened
While the saw blade is tightened securely for immediate
use when it is assembled at the factory, be sure to check
it out again for caution's sake. A saw blade fi xing screw
can be tightened when it is turned clockwise.
Use the provided hexagonal bar wrench to check it
out. For further details, refer to the item of PRIOR TO
OPERATION.
2. Switching on and off
When the lock-off button is pushed forwards, the motor
section can be moved downwards. The saw blade then
emerges from the guard.
<Switching on>
Push the lock-off button forwards and hold, then actuate
the trigger switch.
<Switching off >
Release the trigger switch.
3. Rotational speed preselection
Select the speed at the dial. For recommended speeds,
see Fig. 18.
4. Working Directions
WARNING
○ Do not switch the machine on or off while the saw blade
is touching the workpiece.
○ Let the saw blade reach its full speed before making a
cut.
○ When sawing, never remove the machine from the
material with the saw blade turning.
Allow the saw blade to come to a standstill.
○ If the saw blade blocks, turn the machine off immediately.
○ Do not set the machine down until the saw blade has
come to a standstill.
<Plunge cuts>
The motor section is in the upper position, the saw
blade does not project from the base. Hold the machine
tightly with both hands and place with the base onto the
workpiece. Switch on the machine. Lower the motor
section slowly to the set cutting depth and then move
slowly in cutting direction.
<Sawing along a straight line>
The cutting indicator is used here. The left edge (marked
red) indicates the direction of the cut if the saw blade is
held vertically. The right edge indicates the direction of
the cut if the saw blade is held at 45°. (Fig. 17)
<Sawing along a guard rail secured on the workpiece>
In order to achieve an exact cutting edge, you can attach
a guard rail to the workpiece and then guide the hand-
held circular saw by means of the base along this guard
rail.
CAUTION
○ To avoid abnormal heating of the blade tip or damage to
the saw blade, do not twist or apply excessive force to
the saw blade when cutting. Let the blade move forward
smoothly.
○ In the situation where the circular saw is continuously
operated while replacing the battery with stocked spare
batteries one after another, the motor tends to overheat.
Therefore, whenever the housing becomes hot, give the
saw a break for a while.
○ Avoid cutting operation in a state where the base bottom
is afl oat from the material being cut. Otherwise, the
motor can get locked.

MAINTENANCE AND INSPECTION

WARNING
Be sure to turned off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the saw blade
Since use of as dull saw blade will degrade effi ciency
and cause possible motor malfunction, sharpen or
replace the saw blade as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Motor unit maintenance
The motor winding is an important part of this tool. Avoid
damaging and be careful to avoid contact with cleaning
oil or water.
After 50 hours of use, clean the motor by blowing into the
ventilation holes of the motor housing with dry air from an
air gun or other tool (Fig. 23).
Dust or particle accumulation in the motor can result in
damage.
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun or other tool to clean the lower guard,
ventilation holes or other parts of the product.
4. Cleaning the inside of the guard
Regularly check and clean to make sure that sawdust
and other residue do not collect inside of the saw cover.
Always remove the saw blade when checking and
cleaning (Fig. 24).
5. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
6. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
