Guide Heads Adjustment - Pilous ARG 260 S.A.F. Instruction Manual

Use the tensioning star nut to release the wheel and the blade. Take the saw blade off of 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. 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. Install and close the protective covers of the
saw blade. Turn on the MAIN SWITCH, press the SAFETY button and 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 once of the full length. Switch off the MAIN SWITCH and secure it against restart. As
described in section 4.5, remove the protective covers of the saw blade and check if 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 star nut, so that the disc springs are fully compressed (no light coming through)! Put back the protective covers of
the saw blade, turn on the MAIN SWITCH, press the SAFETY BUTTON and the hydraulic unit. Carry out a saw blade trial run. Switch
off the MAIN SWITCH and secure it against restart, 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. Put back the protective covers of the saw blade, turn on
the MAIN SWITCH, press the SAFETY BUTTON and the hydraulic unit. Carry out the cutting.

4.7. 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 with a minimum play (clearance) between the plates and the
blade.
Guide Head Setting Procedure
Follow the instructions in section 4.5. in order to remove the protective covers. The machine is switched off and secured against
restart, the arm is locked approximately 30 mm above the fixed vice jaw. Set the movable guide head, so that the distance between
the guide heads is approximately 20 cm. Disconnect the inlet hoses from the coolant valve. Loosen the tensioning star, take the saw
blade off the wheels and push it off the guide heads. Unscrew the guide heads gradually from the fixed and movable bars, turn them
by 180 ° (with bearings and hardened steel blade guides facing upwards) and screw back to the bars. Make sure that the guide heads
are perpendicular to the guide bars and that the height of the guide heads is identical. If you find special washers between the guide
head and the bar, make sure you place them back afterwards. Check the tightening of the fixed hardened steel blade guides. Insert
approximately 30 cm of an old saw blade in the guide heads between the hardened steel blade guides and the bearings. Set the
hardened steel blade guides using the width adjusting screw, so that the saw blade does moves between the guides without any play
and jamming. When the saw blade has been adjusted, set the eccentrically mounted bearings in such a manner that the bearings do
