8 Depress spindle lock and securely tighten the bolt.
9 Make sure that the arrow on the blade and the teeth are
rotating counterclockwise.
10 Release spindle lock. Check to be sure that it has fully
released by manually rotating the blade.
11 Replace chip collection unit and securely latch.
(FIG. 1)
(FIG. 2)
12 Replace hex key to holder.
MAKING A CUT
Where possible, always clamp the work piece on a rigid
1
support.
2 Before starting the saw motor:
• Place front edge squarely on the work piece.
• Ensure that the blade is not touching the material to be cut.
• Sight the cutting line with the line of the cut guide.
3 Allow the machine to come to full start.
4 Introduce the blade slowly so as not to damage the teeth
of the blade. DO NOT FORCE THE TOOL. Allow the speed of the
saw blade to do the work.
5 Using both hands, move the saw forward through the work
piece. Applying more pressure on the tool will not improve
cutting performance, but will reduce blade life.
SIGHT LINE NOTCH
1 Use the sight-line notch at front of base plate as guide. (FIg. 5)
The notch represents the kerf of the cut.
(FIG. 3)
(FIG. 4)
2 Align your cut line to the left or the right center of the sight line notch. (Depending on the nal length of the cut piece
required)

3 Laser Beam follows the angle of the base plate.
4 Alight laser beam with your cut line.
5 After completing the cut depress the laser power
switch to disconnect power to laser.
DANGER
LASER RADIATION
Avoid direct eye contact
with light source.
Do not point laser at anyone.
Never look into the laser light.
ALIGNMENT TIPS FOR LASER SIGHT GUIDE
Do not turn on saw
for this adjustment!
Serious injury could result.
(FIG. 6)
Turning the laser o does not turn
power o to the saw.
(FIG. 7)
1 Find a square, at work piece of either steel or plywood
and place the work piece on a table. (Fig. 7)
2 Push the blade guard up and away from the blade.
3 Place the saw on the top of the work piece.
The blade should touch the edge of the work piece. (Fig. 7)
ADJUSTING FOR PARALLEL
Depress power laser power switch. If the laser line does not
line up with the edge of work piece then:
a. For small adjustments use a M2 hex key and loosen
or tighten the screw adjustment. (Fig. 8) to bring
the beam back to parallel.
b. For larger adjustments use a small at head screw
driver to the slot in the front of the light (Fig. 9)
to realign the beam. Then use the M2 hex key and
loosen or tighten the screw in order to do the nal
positioning. (Fig. 10)
c. The laser light and the 2 sight line markings, on the
base plate should now be in the same plane.

MACHINE PREPARATION and OPERATION (Cont.)
ADJUSTMENT OF THE CUTTING DEPTH
With power to the saw turned “OFF”:
1 Release the lock to adjust to the required cutting depth.
(Fig. 11)
2 Make sure that the blade protrudes at the maximum
cutting depth that the saw is capable of in the material
being cut.
3 Tighten to lock into position. Check to ensure that the
lock will not loosen while being used.
NOTE: Metal cutting blades work best while having the maximum
amount of blade engaged in the cutting action. This distributes the
cutting load among the teeth on the blade. This is the opposite of
how a wood cutting blade is used, where minimal blade protrusion
allows the operator to make a cut while minimizing the potential for
the blade to become bound in the cut and produce material tearout.
EXCEPTION: Metal grating is best cut by having the blade protrude
very minimally beyond the depth of the grating. The interrupted cuts
that occur when cutting grating are very hard on the blade and
carbide tips.
BEVEL CUTTING ADJUSTMENTS
(g…)
(FIG. 11)
Adjusting a saw with the power
connected could lead to an injury
if the saw started suddenly.
Never connect the saw to a power
source until all adjustment steps
are completed.
Do not use machine for
plunge cutting.
Serious injury could occur.
1 Loosen bevel handle (Fig. 12)
2 Adjust to the required cutting angle by lining up the bar
on the bevel handle with the degree needed on the scale.
3 Tighten bevel handle.
For certain compound cuts it
may be necessary to manually
retract the guard to allow the
blade to enter into and / or through the cut. Be extremely careful when
PARALLEL BLADE GUIDE
making these cuts,as the guard will not protect you from injury.
PARALLEL BLADE GUIDE
To set the guide:
1 Loosen the retaining screw. (Fig 13)
2 Slide the guide up snugly against the side of the work piece.
3 Using a measuring tape, check that the distances from the
front and the back of the blade to the edge of the blade
guide are equal. This will ensure that the guide is parallel
to the blade. The guide should be parallel to the blade,
and not to the base of the tool, to avoid damage to both
blade and motor.
4 Retighten the screw.
