OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.
Prior to Operation
• Make sure the guards have been mounted correctly.The
saw blade guard must be in closedposition.
• Make sure the saw blade rotates in the direction of the
arrow on theblade.
• Do not use excessively worn sawblades.
Mounting the Dust Extraction Port (Fig. A, E)
Your circular saw is supplied with a dust extractionport.
To Install the Dust Extraction Port
1. Fully loosen depth adjustment lever
4
.
2. Place the shoe
5
in the lowestposition.
3. Push the dust extraction port
22
onto the circular saw
upper guard and align with the mounting holes. Secure
dust extraction port to the upper guard using the two
screws
24
provided.
Mounting and Adjusting the Rip Fence
(Fig. M)
The rip fence
26
is used for cutting parallel to the edge of
theworkpiece.
Mounting
1. Slacken the rip fence adjustment knob
25
to allow the rip
fence topass.
2. Insert the rip fence
26
in the base plate asshown.
3. Tighten the rip fence adjustment knob
25
.
Adjusting
1. Slacken the rip fence adjustment knob
25
and set the rip
fence
26
to the desired width.The adjustment can be read
on the rip fencescale.
2. Tighten the rip adjustment knob
25
Kerf Indicator (Fig. A)
The front of the saw shoe has a kerf indicator
9
for vertical
and bevel cutting. This indicator enables you to guide the saw
along cutting lines penciled on the material being cut. The kerf
indicator lines up with the left (inner) side of the saw blade,
which makes the slot or “kerf” cut by the moving blade fall to
the right of the indicator. Guide along the penciled cutting line
so that the kerf falls into the waste or surplusmaterial.
Bevel Angle Adjustment (Fig. A, I)
The full range of the bevel adjustment is from 0° to 50°. The
quadrant is graduated in increments of 1°. On the front of the
saw is a bevel angle adjustment mechanism consisting of a
calibrated quadrant and a bevel adjustment lever
10
.
Cutting Depth Adjustment (Fig. A, H)
1. Hold the saw firmly and loosen (clockwise) the depth
adjustment lever
4
and move shoe (
5
, Fig.A) to obtain the
desired depth ofcut.
2. Make sure the depth adjustment lever has been retightened
(counterclockwise) before operatingsaw.
For the most efficient cutting action, set the depth adjustment
so that one‑half tooth of the blade will project below the
material to be cut. This distance is from the tip of the tooth to
the bottom of the gullet in front of it. This keeps blade friction
at a minimum, removes sawdust from the cut, results in cooler,
faster sawing and reduces the chance of kickback. A method
for checking for correct cutting depth is shown in FigureH. Lay
a piece of the material you plan to cut along the side of the
blade, as shown, and observe how much tooth projects beyond
thematerial.
Blades

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle material.
Foreign objects in the workpiece such as wire or nails
can cause tips to crack or break. Only operate saw when
proper saw blade guard is in place. Mount blade securely
in proper rotation before using, and always use a clean,
sharpblade.

WARNING: Do not cut metal, plastic, concrete, masonry
or fiber cement materials with thissaw.
Do not use abrasive wheels or blades. A dull blade will cause
slow inefficient cutting, overload on the saw motor, excessive
splintering, and could increase the possibility of kickback.
Please refer to the table below to determine the correct size
replacement blade for your modelsaw.

Checking the Lower Guard(Fig.A)
1. Turn tool off and disconnect from powersupply.
2. Rotate the lower blade guard retracting lever
6
from the
fully closed position to the fully openposition.
3. Release the lever and observe the guard
7
return to the
fully closedposition.
The tool should be serviced by a qualified service center if it:
• fails to return to the fully closed position,
• moves intermittently or slowly, or
• contacts the blade or any part of the tool in all angles and
depth ofcut.
To Set the Saw for a Bevel Cut
1. Loosen (counterclockwise) the bevel adjustment lever
10
and tilt shoe (
5
, Fig.A) to the desired angle by aligning the
pointer with the desired anglemark.
2. Retighten lever firmly (clockwise).
