Guide Head Setting Procedure
Disconnect the machine from the mains and secure it against restarting. Raise the arm to the upper position. Set the movable guide
head, so that the distance between the guide heads is approximately 15 cm. Disconnect the inlet pipes from coolant valves (if the
machine is equipped with a saw blade cooling system). Remove the protective covers of the saw blade and the back cover of the
arm. 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 25 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 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. Make
sure that all bolt connections are tight. Unscrew the guide heads from the bars. 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. You can achieve the correct guide head height in relation to the saw blade by lifting the
guide heads, so that the upper hardened steel guide in the guide head is about 0.5-1 mm from the upper edge of the saw blade. See
the picture. In this way, the correct guide head height towards the guide bars is achieved.

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.
