OPERATION
4. PLACE WORKPIECE
Place the workpiece flat on the table with one edge se-
curely against the fence. Turn on the laser to see where
the cut will land on the material (See Page 17 “Using
the Laser”).
Warped Boards:
If the board is warped, place the
convex side against the fence (Fig. 17 - 1). CAUTION:
The board could break and jam the lade if the concave
side is placed against the fence
Long Boards:
When cutting long workpieces, support
the opposite end of the material with the support table, a
roller stand or a work surface that is level with the saw table.
5. SECURE WORKPIECE
Secure the workpiece with the clamping device on the
fixed table whenever possible to prevent the material
from moving during the cutting operations. Position
the clamp (Fig. 17 - 2) in the position that does not
interfere with the travel of the saw. Tighten it in place
with the two clamp lock screws. Lower the clamp knob
(Fig. 17 - 3) to clamp the workpiece and tighten.
3. SLIDING FUNCTION
For materials width<4 inches (100 mm)
When cutting materials with a width less that 4 inches,
the sliding mechanism isn’t necessary. Loosen the slide
lock knob (Fig. 16 - 1) and use the operating handle to
push back the saw arm. Tighten the slide lock knob.
For materials width >4 inches (100 mm)
When cutting materials with a width longer that 4 inch-
es, the saw arm will need to slide to cut through the
workpiece. Loosen the slide lock knob so the saw arm
can slide through the entire workpiece.
NOTE:
When cutting metal, it is very important to clamp down the workpiece as any movement of the metal
workpiece will cause damage to the blade.
6. SELECT THE SUITABLE SPEED
Select the suitable speed for the material being cut. Do not change the blade speed while the miter saw is running.
1. LOW SPEED: 2000 RPM, recommended for cutting mild steel.
2. HIGH SPEED: 4500 RPM, recommended for cutting wood, plastic, aluminum, bronze alloy and copper alloy.
