(clockwise) firmly with the blade wrench (FIG. 3).
NEVER ENGAGE BLADE LOCK WHILE SAW IS RUNNING, OR
ENGAGE IN AN EFFORT TO STOP THE TOOL. NEVER TURN
SWITCH ON WHEN BLADE LOCK IS ENGAGED. SERIOUS
DAMAGE TO YOUR SAW WILL RESULT.
When removing the blade, first unplug the saw. Engage the blade
lock and unscrew the blade clamping screw by turning it counter-
clockwise with the blade wrench.
CUTTING DEPTH ADJUSTMENT
DISCONNECT PLUG FROM POWER SUPPLY.
Hold the saw firmly as shown in Figure 4. Loosen
(counterclockwise) the Depth Adjustment Lever and move shoe to
obtain the desired depth of cut, as shown in Figure 5. Make sure
the Depth Adjustment Lever has been retightened (clockwise)
before operating saw.
Your saw is equipped with a carbide tipped saw blade for long life
and efficient cutting.
For the most efficient cutting action using a carbide tipped saw
blade, set the depth adjustment so that about one half of a tooth
projects below the surface of the wood to be cut. The height of a
whole tooth is the distance from the tip of the tooth to the bottom of
the gullet in front of it. Study Figures 5A and 5B to determine what
one half tooth means. (5A shows one half tooth projecting below
the surface and figure 5B shows a whole tooth projecting below the
surface.)
Setting the saw at the proper cutting depth keeps blade friction to a
minimum, removes sawdust from between the blade teeth, results in
cooler, faster sawing and reduces the chance of kickback.
A method of checking for the correct cutting depth is shown in Figure
6. Lay a piece of the material you plan to cut along the side of the
blade, as shown in the figure, and observe how much tooth projects
beyond the material.
NOTE: When using a non carbide tipped blade, make an exception
to the above procedure and allow a full tooth to project below the
material, as shown in Figure 5B.
