Adjusting Feed Rate (Cutting Pressure)
To obtain desired feed rate (c utting pressure), the “hydraulic cylinder” (Fig 3, #4) and “ feed tension
spring” (Fig 3, #6) are to be adjusted together.


Feed pressure is the amount of pressure forcing the blade downward into the material.

Proper feed pressure is important. Excessive pressure can break the blade or stall the saw.
Insufficient pressure rapidly dulls the blade.

The hydraulic cylinder regulates the rate at which the blade is lowered into the material being cut.
Adjusting the
blade descend speed control knob provides an infinite choice for feed rate.

When cutting workpiece of 2 mm thick or below, please adjust the blade descend speed control
knob to between “1~2” gradually; when cutting workpiece of 3 mm and above, to “3~4” gradually.
The by-pass valve (Fig 3, #2) has been factory adjusted and should not be altered.

Using blade descend speed control knob while repositioning your workpiece: When repositioning
your workpiece, raise the saw head halfway up and turn the blade descend speed control knob
clockwise all the way pass “0” to hold the saw head in position.
Adjusting Vise
Always use the vise to clamp the work. Never hand-hold the work for cutting.
Clamp material securely by turning the vise handwheel clockwise.
