ADJUSTING THE RAIL Now aim and measure along the string to check that the distance between the string and the rail is consistent along its entire length. To adjust the straightness, move the rail pieces up or down where the straightness deviates. Tip: Place shims under the rail components so that you can control the...
B751 PRO MOUNTING THE SAW HEAD ON THE RAIL Lift the saw head into place on the rail. The saw head weighs 178 kg in total. Use a sling approved for the purpose and attach to the saw head’s lifting eyes. Lift the saw head using the appropriate lifting gear.

B751 PRO ADJUSTMENT SEQUENCE Read through all the set-up instructions before starting to set up, then follow the instructions step by step as you work. IMPORTANT!! It is important to adjust the saw head before starting to ensure satisfactory sawing and the correct functioning of the sawmill. Follow the adjustment sequence meticulously.
Page 24
ADJUSTMENT SEQUENCE ADJUST THE RAIL HORIZONTALLY It is important that the rail is completely level so as to ensure that it functions well. We have previously set the straightness of the rail in longitudinal direction. Now the rail has to be adjusted horizontally along the short side.
Page 25
B751 PRO Loosen the locking screw ADJUSTMENT SEQUENCE LONGITUDINAL BLADE POSITION The longitudinal blade position over the wheels is adjusted using the horizontal adjusting screws, i.e. the screws on the outside of the axle mountings. The lock nut must be opened first when adjusting the blade position.
Page 26
ADJUSTMENT SEQUENCE Measurement Measurement point 1 point 2 X mm X mm ADJUST THE SAW BLADE PARALLEL TO THE LOG BEDS It is important for the saw blade to be parallel to the log beds to ensure the proper functioning of the sawmill. Measure the distance vertically down from the blade to the log bed, then note down the values.
Page 27
B751 PRO ADJUSTMENT SEQUENCE TENSION THE BLADE GUARD ARM It is important for the blade guard arm to move smoothly in the attachment plate to ensure proper functioning of the sawmill. Release the Allen head bolt on the blade guard plate, then push the wheel downwards using a screwdriver as illustrated.
Page 28
ADJUSTMENT SEQUENCE Measurement point 1 ADJUST THE BLADE SO THAT IT IS PARALLEL TO THE RAIL It is important for the saw blade to be parallel to the rail to ensure the proper functioning of the X mm sawmill. Place a straightedge on the saw blade, as close to one of the blade guide rollers as possible.
B751 PRO OTHER SETTINGS Read through all the set-up instructions The following settings are important for before starting to set up, then follow the satisfactory operation of the sawmill, but instructions step by step as you work. they do not affect one another and so there is no need to implement them in any particular order.
Page 30
OTHER SETTINGS LOG SUPPORT It is important for the relationship between the log bed and the log support to be perpendicular to ensure the proper functioning of the sawmill. This is adjusted by turning the adjustment handle in the lower part of the log support.
Page 31
B751 PRO OTHER SETTINGS SET THE CRANK SPRING Tighten the lock nut in order to tension the spring so that the handle snaps back easily and locks in the crank pulley. When the handle is working properly, bend the lock washer to secure the lock nut in position.
SAWMILL FEATURES CRANK FEATURE The crank used to move the saw head up and down is spring-loaded and must be pushed against the machine to release the locking mechanism while raising or lowering the saw head. 360 = 1 inch The crank locking mechanism is divided into eight positions on a single rotation.

RELATIVE GAUGE, B751 PRO BLADE-COMPENSATED mm/Inch SAWMILL FEATURES GAUGE FEATURE GAUGE, MM/INCH The sawmill has two gauges: a millimetre gauge showing the distance between the log bed and the saw blade, and a blade-compensated gauge LAST CUT INDICATOR showing a range of different board thicknesses in inches.
SAWMILL FEATURES WATER COOLING Water cooling is controlled by means of a lever in the side panel in front of the operator. The lever is perpendicular to the panel in its initial position. The lever is pulled backwards to turn on the water flow.
