7.5 Blade tracking adjustment

Warning:
Blade tracking adjustment requires
running the saw with the wheel
cover open. This adjustment must
be completed by qualified persons
only.
Failure to comply may cause
serious injury!
The blade tracking has been set at the
factory and should not need
adjustments.
Confirm that the blade tension is set
properly.
Run the saw at lowest speed.
The blade should run next to but not
tightly against the wheel flange.
If blade tracking needs to be adjusted
loosen the bolt (A, Fig 12).
Fig 12
Turning the set screw (B) clockwise
tracks the blade closer to the wheel
flange.
The tracking is sensitive, start with ¼
turn of the set screw.
Once tracking is set, tighten bolt (A)
firmly.

7.6 Feed speed adjustment

You can control the sawblade
downward feeding with the valve
control knob (G, Fig 13) and lock the
saw with the on/off valve (F).
Fig 13
The cutting of thin-walled workpieces
(profiles, tubes etc.) requires slow
feeding to avoid excessive wear of
sawblade.
A good indication of proper feed speed
is the shape of the cutting chips. If the
chips are thin or powdered increase
the feed speed.
The stop screw (H) prevents the blade
from contacting the base after the cut.
7.7 Vice adjustments
To open and close the vice use the
handwheel (Fig 14).
Fig 14
Vise positions:
There are two sets of holes in the base
for mounting the vise.
For miter cuts from 0° up to 45°, mount

For miter cuts over 45° up to 60°, use
the vise in the right set of holes.
