Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the rotating disc.
Corners, sharp edges or bouncing have a tendency
to snag the rotating disc and cause loss of control or
kickback. 5) Do not attach woodcarving rotating discs
or toothed saw discs. Such discs create frequent
kickback and loss of control. 6) Do not use an
oversized rotating disc. Follow the ecommendations
of Werku
®
when selecting a rotating disc. A larger
rotating disc presents a laceration hazard and may
cause snagging, tearing of the disc or kickback.

USE INSTRUCTIONS.
Before starting up the circular saw, we recommend
that you carefully read all of the instructions as
indicated. Please respect all regulations regarding the
prevention of accidents, health and safety directives,
laws and applicable restrictions for work places. The
circular saw must only be used by persons who have
been instructed in its use and only for the purposes
for which it has been designed.
POWER SUPPLY.
Make sure the power supply is adapted to the
requirements shown on the information panel of the
circular saw (1). Using the motor at low voltage will
make it operate slowly. This will reduce performance
and may cause the motor to overheat.
EXTENSION CORD.
If the working area is at some distance from the power
supply, use an extension cord of enough diameter
and quality.
ATTACHING SAW DISC.
Always disconnect the plug from the power source
before making any adjustments or attaching any
accessories. Turn disc stud counter-clockwise and
remove disc stud and outer washer (2). If the shaft
moves while attempting to loosen the blade stud, strike
the wrench counter-clockwise to jar loose. Make sure
the saw teeth and arrow on the disc point in the same
direction as the arrow on the guard (3). Slide disc
through slot and mount it against the inner washer on
the shaft. Be sure the large diameter of the inner and
outer washer lay flush against the disc. Reinstall outer
washer and tighten disc stud finger tight (2).
DEPTH ADJUSTMENT.
Disconnect plug from power source. Loosen the
depth adjustment lock screw located between the
guard and handle (4). Hold the shoe down with one
hand and raise or lower saw by the handle. Tighten
lock screw at the depth setting desired.
SAFETY SWITCH.
When starting the circular saw, hold it with both hands
since the torgue of the motor can cause the circular
saw to twist. The safety switch is designed to prevent
accidental starts. To start the circular saw, press the
release button located on the handle with your thumb
and pull the trigger simultaneously (5). To switch the
machine off, release the trigger. The safety switch
will engage automatically.
CUTTING.
Disconnect the plug from the power supply before
making any adjustments. Set the depth adjustment
based on the thickness of the material to be cut (4).
With the disc barely above the material to be cut,
start the saw and allow the disc to come to full speed.
Gradually lower the disc unto the material to be cut
using the front end of the shoe as a pivot point. When
the disc starts cutting, release the lower guard. When
the shoe is resting flat on the surface being cut,
proceed cutting in a forward direction to the end of
the cut. Allow the disc to come to a full stop before
removing it from the cut. Never pull the machine
backward since the disc will climb out of the cut and
kickback will occur (6). Turn the circular saw around
and finish the cut in a normal manner, sawing forward.
