t u m
the knob of the flow control valve to
1-2; if the workpiece thickness is bigger than 3 mm, set the knob to 3-4.
While settling the cutting material, the sawhead can be held at the middle position of the whole
rising distance by turning the flow control valve to the zero position.
CAUTION :
If the sawhead is forced downward by external force, the hydraulic cylinder will be damaged.
By-Pass Valve has been properly adjusted in factory, please DO NOT reset it.
PRESET ADJUSTMENTS: (Do not adjust unless necessary)
1. Place a level on the bed (No. 4 in Fig) to obtain the leveling, as shown in Figure below.
2. Loosen the lock nut

The saw bow should stop simultaneously or slightly before the screw in the above figure hits the bed.
This automatic stop is activated by the lower limit switch. These two stopping mechanism are both
pre-adjusted Please do not re-adjust unless necessary.
Limit Switches and Automatic Shut-off:
In manual mode, the motor shuts off immediately after the blade has cut through the material. In auto
mode, it shuts off when the last cut is executed. The shut off is activated by depressing the lower limit
switch just before the head comes to rest to a horizontal stop. The upper limit switch also has the same
function, however it is designed to be adjusted easily to save downfeed air time. If you are
encountering incomplete cut-off of the stock, it may be the lower l i t switch has moved due to
-
constant use. You may adjust the height of the stopper (beneath lower limit switch) for minor
