(3) Please watch over the obstacle or personnel that may be on the way of moving the
machine.
(4) Place the machine on a horizontal foundation. Use anchor bolt and nut to fix the
machine.
3.3 Connecting Electric Power
Note:
(1) Assure the main power switch is at “OFF” position and the saw blade motor
speed select switch is at “OFF” position before connecting the machine to
electric power source
(2) Do not install saw blade on the main shaft when checking the rotational
direction of the main shaft.
(1) Only qualified electrician can connect electric power.
(2) The voltage, amperage and protection capacity of the power source shall meet the
requirement of the machine.

9
(3) Check the rotation of the saw blade shaft (arbor). Change over two conductors in
junction box if the direction of rotation does not consist with the direction of the label
on the saw blade safety cover.
3.4 Filling coolant
(1) Pour the diluted sawing oil on the table of the machine. The solution will flow into
the coolant tank.
(2) The dilute ratio (water: oil) is 5:1 for hard or high alloy steel and 10:1 for mild steel.
3.5 Procedure to install the stopper
(1) Mount the stopper arm at the “0” point on the stopper support beam as illustrated on
following figure1.
(2) Put the stopper support beam into the hole in the base plate.
(3) Fix the stopper support beam when the stopper is just touching the sawblade as
illustrated on following figure2.

10
4. FUNCTION OF CONTROL SWITCHES
(1) Trigger Switch
This is an "ON-OFF" two-position trigger switch on the handle to connect or
disconnect power to the machine. The main (saw blade) motor and coolant motor run
when this switch is pressed. The above motors stop when this switch is released.
(2) Saw Blade Motor Speed Select Switch
This is a "LOW-OFF-HI" three-position level switch on the top of motor for selecting
a suitable speed for the saw blade to cut material.

5. INSTRUCTION OF OPERATION
5.1 Preparation for Operation
5.1.1 Adjustment of the Clamping Vise
(1) Release the handle.
(Cutting head shall be at up position)
(Saw blade motor shall stop.)
(2) Turn the vise hand wheel counter-clockwise to open the vise.
(3) Put a work piece into the clamping area of vises.
(4) Turn the vise hand wheel clockwise to close the vise and fasten a work piece.
(5) Turn the vise hand wheel 1/2 (half) turn counter-clockwise to open the vise slightly.
This is the ready position to take in or remove a work piece.
5.1.2 Installation of the Saw Blade
(1) Release the handle.
(2) Turn off the saw blade motor speed select switch.
(3) Open saw blade safety cover.
(4) Remove the clamping flange from the saw arbor.
(5) Clean the clamping surfaces of flange and arbor free from any dirt or chips.
(6) Clean the clamping area of the saw blade.
(7) Mount saw blade on the arbor. Align the pinholes of saw blade and arbor. Put the
clamping flange on the saw blade, and tighten the center bolt.
Note: The rotation of saw blade shall be counter-clockwise while looking at the
mounting surface. There is a directional mark labeled on the protection cover.
(8) When lock the center bolt, keep the front part of saw blade downward to eliminate
the gap between pin and pinhole.
(9) Close the saw blade safety cover.
Note: The following Charts of " Number of Saw Blade Tooth Selection " are for reference.
