Connect the machine to the mains and press the MAIN SWITCH. The TOTAL STOP button is unlocked. Start the MANUAL MODE,
switch on the HYDRAULIC UNIT - START. Switch the ARM END STROKE SWITCH into position 0 in order to control fully the arm
movement via the touch screen. Raise the arm into the upper position by pressing the SAW BLADE UPWARDS button and stop the
uplift by pressing the STOP button on the display. Shut off the control valve (see section 4.2.). Start the saw arm descent and by
gradually releasing the CONTROL VALVE move the arm to about 30mm (in ARG 330) above the fixed jaw of the vice (50 mm in other
types) and close the CONTROL VALVE. Switch off the MAIN SWITCH and secure it against restart.
Open/remove the protective covers of the saw blade (see section 4.6.). Use the tensioning star nut to release the wheel and the
blade. Take the saw blade off the moving wheels and push it off the guide heads. Insert the new saw blade in the guide heads. Place it
on the blade wheels (you can control the position of the tensioning wheel by the tensioning star nut). Tighten the saw blade.
Close/put back the protective covers of the saw blade and turn on the MAIN SWITCH. Turn on the
hydraulic unit, switch to the MANUAL MODE and set the minimum saw blade speed by a SAW BLADE SPEED CONTROLLER.
Press the START button of the saw blade to start the saw blade so that it turns approximately one full length. Switch off the MAIN
SWITCH and secure it against restart. Open/remove the protective covers of the saw blade to make sure that the saw blade is
correctly fitted on the guide heads and correctly installed on the blade wheels (see figure). The machine is also fitted with a control
hole that allows you to check the condition of the saw blade on the wheels. The hole is covered by a cap.
If the saw blade is not properly set on the wheels, loosen the saw blade a little bit and use the wheel tilting screw to adjust the wheel tilt.
Tension the saw blade again and close/put back the protective covers of the saw blade.
Turn on the MAIN SWITCH and the hydraulic unit. Carry out a saw blade
trial run. Switch off the MAIN SWITCH and secure it against restart, open/remove the protective covers of the saw blade and once
again check the placement of the saw blade on the wheels. Repeat the procedure, if required. Close/put back the protective covers of
the saw blade and turn on the MAIN SWITCH and the hydraulic unit. Carry out the cutting.
4.8. Guide Heads Adjustment
The correct setting of the bearings and the hardened steel blade guides in the guide heads substantially influences the saw blade life
and the quality of the cut. The eccentrically arranged guide head bearings must be set in such a manner that the saw blade surface is
parallel to the surface of hardened steel blade guides. One of the hardened steel blade guides is fixed firmly, the other one is
adjustable.
Guide Head Setting Procedure
Raise the saw blade approx. 30 mm (in ARG 300) above the fixed vice jaw (50 mm in other types). Switch off the MAIN SWITCH and
secure it against restart. Disconnect the coolant supply hoses from the guide heads and the control head (the hydraulic hoses must
never be disconnected!). Loosen the tensioning star nut in order to loosen the saw blade. Open/remove the protective covers of the
saw blade. Take the saw blade off the moving wheels and push it off the guide heads. Unscrew the guide heads gradually from the
fixed and moving guide bars and clean them thoroughly. Fasten the guide heads to the fixture approx. 350 mm from each other and
turn them through 180° (with bearings and hardened steel blade guides upwards). Make sure that the guide heads are perpendicular
to the guide bars and that the height of the guide heads is identical. Check the tightening of the fixed hardened steel blade guides.
Insert approximately 50 cm of an old saw blade in the guide heads between the hardened steel blade guides and the bearings. When
the saw blade has been adjusted, set the eccentrically mounted bearings in such a manner that the bearings do not “cut” the saw
blade, but at the same time you have to prevent too much space for the saw blade between the bearings. When the saw blade moves,
the bearings are carried along by the saw blade. Adjust the control bearing with the control cylinder liner so that the bearing axis is
perpendicular to the saw blade. Make sure that all bolt connections are tight. Unscrew the guide heads from the fixture. Fit the saw
blade on the wheels, check its correct alignment on the wheels and tension the saw blade. Install both guide heads on the saw blade
in the space between the bars and adjust them in the correct position on the bars. In this way, the correct guide head height towards
the guide bars is achieved. Adjust the heads in such a way that the saw blade is in perpendicular position to the machine table and
tighten them. Connect the coolant hoses and the saw blade pressure control heads. Close/put back the protective covers of the saw
blade and turn on the MAIN SWITCH. Switch on the hydraulic unit and carry out a short trial run of the saw blade. Switch off the MAIN
SWITCH and secure it against restart. Open/remove the protective covers of the saw blade and check the placement of the saw
blade on the wheels. Make a correction, if necessary - see section 4.7.. Close/put back the protective covers of the saw blade and
turn on the MAIN SWITCH and the hydraulic unit. Carry out the cutting.
Tension
the star nut, so that the disc springs are fully compressed (no light coming through)! In this way, you can achieve correct
tensioning of the saw blade.
Tension the star nut, so that the disc
springs are fully compressed (no light coming through)!
Caution! You can remove protective covers only if the power switch is turned off and
secured against restart or if the machine is disconnected from the mains.
Caution: Danger of injury by the sharp teeth of the saw blade. Use protective gloves. Do not
reach between the wheels and the saw blade.
