Refer to fig.5
4.6.2.
Adjust the swivel arm of the saw blade holder according to the size of the saw blade and the position of the motor block where
necessary.
4.6.3.
After loosening the knob, the arm (2) can be pulled out and turned (1). The mandrel, to which the arm is attached, can also be
moved within the slot in the base plate (3). A multitude of adjustments are possible for every diameter of saw blade between 90cm and
400cm. The motor block can also be moved back and forth on the base plate (4), for bigger blade diameters.
4.6.4.
during grinding the stone is moved backwards and forwards by means of the lever. The lever must be pulled toward the saw blade when
adjusting the correct position, so that the grinding stone can lock into the tooth bottom.
4.7.
adJustment eXamples for different saw blade diameters
Refer to fig.6.
4.7.1.
(A) 90mm saw blade, motor moved backwards.
4.7.2.
(B) 230mm saw blade, motor must be moved forward in order to avoid any collison with the arm.
4.7.3.
(C) 400mm saw blade, motor moved forward, arm must be aligned in such a way that the pin nut does not collide with the saw blade.
4.8.
depth gauge
4.8.1.
After adjusting the correct position of the arm, motor and saw blade, the depth gauge needs to be adjusted.
4.8.2.
To adjust the depth gauge, position the grinding stone into the tooth bottom, so that the tooth face can be completely sharpened, but the
grinding stone does not touch the tooth bottom (there must be a space of some mm). Tighten the fastening screw of the depth gauge to
fix the correct position. (See fig.7).
4.9.
saw blade support
4.9.1.
For better stability and more accurate positioning, it is necessary to place the saw blade support as close as possible to the grinding
stone, so that the saw blade can rest on it. (See fig.1).
4.10.
saw blades with set teeth
4.10.1.
For saw blades with set teeth the motor can be tilted. Unscrew the fixing nuts on both sides of the motor retainer and adjust to the
desired angle. The motor can be tilted up to 25° in both directions. (See fig.8). It might be possible that the desired angle
cannot be reached as the motor touches the base plate for large angles. In this case turn the motor block by 180° within the collar of the
motor holder (loosen the clamping screw, (see fig.1) on the neck of the motor). (See fig.8).
4.11.
sharpening of circular saw blades
4.11.1. After all the adjustments have been completed, position the locking pin in such a way, that it will put slight pressure on the saw blade
.
(See fig.9).
4.11.2. Switch the machine on to start the sharpening process and operate the lever to move the grinding stone towards the tooth until it has
reached the adjusted depth gauge.
4.11.3. Pull back the grinding stone (by the operating lever) and turn the saw blade to sharpen the next tooth. Repeat these steps until all teeth
have been sharpened.
note:
In case of set teeth, only grind every second tooth and then reverse the angle to grind the remaining teeth.
4.11.4.
When grinding the tooth back make sure the grinding stone and saw blade are orientated as shown in fig.3.
