4.6 Blade tracking adjustment (Hydraulic
blade tension type)
This adjustment must be accomplished by
qualified personnel that are familiar with this type
of adjustment and the dangers associated with it.
The blade tracking has been set by factory and
should not require any adjustment. If a tracking
problem occurred, adjust the machine as follows:
- Raise saw arm to a usable height.
- Disconnect the machine from the power source.
- Locate tracking adjustment bolt on the backside
of the saw bow behind the flywheel.
- Loosen hex cap screw C, located on the top of
the track-adjusting bolt A and tracking nut B .
- Either raising or lowering track-adjusting bolt A
accomplishes track adjusting.
- Tracking is set properly when the back of the
blade lightly touches the wheel flange. Note:
over tracking (allowing blade back to rub hard
against wheel flange) will damage the blade
wheels and blade.
- Tighten hex cap screw C and tracking nut B.
- Connect machine to the power source.
4.7 Placing the saw blade onto the drive
wheel and flywheel
- Disconnect from power supply
- Remove the blade guards
- Turn the blade tension handle counter-
clockwise, to fully loosen the flywheel.
- Open the blade cover and place the saw blade
onto the race of the drive wheel and flywheel.
*Check the cutting direction of the saw blade.
- Insert the saw blade into the rollers of the left
and right blade guide.
- The back edge of the saw blade should make
contact with the flange of the drive and flywheel;
turn clockwise the blade tension handle to
tighten the saw blade, until the blade is properly
tensioned.
- Replace the blade guards.
- Use the blade running switch 3.1N to check the
proper ride of the blade.
4.8 Hydraulic vise pressure
The hydraulic vise pressure can be monitored and
adjusted by a pressure gauge on the base of the
machine. The normal pressure is set at
35kgs/cm
2
. This is good for most solid firm
materials. For softer, hollow, or pipe materials
reduce the pressure to over 25kgs/cm
2
. Other
materials may require different clamping force.
The clamping pressure may be adjusted by a
knob at the base of the pressure gauge assembly.

- Start by pressing the vise close switch (3.1G)
continuously in manual mode to have the vise
clamp onto a work piece.
- Next, unlock the fluted knob (Z) by releasing
fluted lock nut (Z1).
- Turn the fluted knob (Z) counterclockwise to
decrease the pressure, clockwise to increase
the vise pressure.
- Lock the fluted nut (Z1) after adjustment.
5 OPERATION PREPARATIONS
5.1 Setting the stroke limit
Waterproof cover
The numerical bow stroke height adjusting switch
is covered with waterproof cover, set the bow
height need to open the cover, after setting bow
raise up stroke already, cover the cover to prevent
the coolant permeate into the switch to cause the
switch damaged.
