ADJUSTMENT SEQUENCE
In this case, the blade body
is defined as the part of the
blade that is between the
bottom of the tooth and the
trailing edge of the blade.
If the blade curves in the sawing direction, the blade
is too far forward on the wheels. If it curves in the
other direction, it is too far back.
DRIVE BELT
WHEEL
BLADE BODY
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. The adjusting screw must be
turned clockwise to compensate if the saw blade
wanders forward on the wheels. Turn the screw
anticlockwise if the blade wanders backwards.
Adjust in small increments. Tighten all lock nuts
and adjusting screws when adjustment is complete.
TIP: You may need to loosen the upper adjusting
screw slightly before adjusting the blade.
LONGITUDINAL BLADE POSITION
LONGITUDINAL BLADE POSITION
The position of the saw blade in the longitudinal
direction is important for the sawing result.
Positioning the blade with the blade body centred
over the drive belt located in the recess in the wheel
is recommended for best results.
Start by fitting the blade so that the protrusion
on both sides of the drive belt to the sides of the
blade body are of the same size. Then tension the
blade. Spin the wheels manually and check that the
longitudinal blade position on the wheels remains
unchanged. Spin the wheels through at least three
revolutions. Perform adjustment as instructed in
the next paragraph if the blade wanders forward
or back on the wheels. If the blade runs straight on
both wheels, check that the blade runs in a straight
line between the wheels. This is checked by looking
along the trailing edge of the blade on the top of
the wheels.
When the blade is running in a straight line. Close
the covers and start the sawmill. Open the throttle
so that the wheels start to turn, then release
the throttle. Open the covers and check that the
longitudinal position of the blade is unchanged.
If so, the setting is correct.
