Saw Blade Feed Into Cutting Position - Pilous ARG 220 D Instruction Manual

Guide Head Setting
Elevate the saw blade approx. 20 mm above the fixed gripping jaw of the vice. Switch off the master switch, isolate the machine from
supply and secure it against restarting. Adjust the moving guide head so that the guide heads are approx. 20 cm from each other.
Disconnect the supply hoses of the coolant valves. Unscrew the guide heads gradually from the fixed and moving guide bars, turn
them through 180° (bearing and carbide guide upward) and screw to the bars again. Observe the perpendicularity of the guide heads
to the bars and the identical height of the guide heads. Check the tightening of the fixed carbide guides. Insert approx. 30 cm of an old
saw blade in the guide heads between the carbide guide and the bearings. Set the pressure carbide guides with the width setting
screw of the carbide guides so that the saw blade moves without clearance between the carbide guides, but does not seize. When
the saw blade is correctly set, adjust the eccentrically arranged bearings to prevent the bearings from "cutting" the saw blade but
there must not be big clearance between the bearings. When the saw blade moves, the bearings are carried along by the saw blade.
Check all the bolt connections for tightening. Unscrew the guide heads from the bars. Fit the saw blade on the moving wheels,
checks its correct alignment on the moving wheels and tension the saw blade. Install both guide heads on the saw blade in the space
between the bars and adjust their correct position on the bars. Than we move guiding heads up, so that the space between fixed
carbide guides and upper part of saw band was approx 0,5-1mm. In this way, the correct guide head height towards the bars is set.
Adjust the guide heads perpendicularly to the bars and tighten them. Close the rear head protective enclosure, switch on the master
switch or connect the machine to the network. Switch on the hydraulic unit and carry out a short test run of the saw blade. Switch off
the master switch, isolate the machine from supply, open the rear head protective enclosure and check the saw blade fitting on the
moving wheels and guiding heads. Make corrections, if required (see 5.3.1.). Close the rear head protective enclosure, connect the
machine to supply, switch on the master switch and hydraulic unit. Carry out the first cut.

5.4. Saw Blade Feed into Cutting Position

The control valve is situated on the central control board. It enables a continuous setting of the speed of the saw blade feed into the
cutting position or its stabilization in any position by turning the valve mechanically. The examples of descent speed are shown in
chapter 11.6. The optimum value can also be determined very easily by listening. The saw blade movement must be noiseless, free
from vibrations. This condition can be achieved if the pressure force is increased or decreased (head decent speed). The condition
for setting the optimum pressure is the selection of the correct cutting speed of the saw blade and the optimum size of the saw blade
teeth.
