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 blots (A, Fig 9).
Tracking adjustment is accomplished
by either loosening or tightening three
adjusting nuts (B).
Fig 9
The tracking is sensitive, start with ¼
turn adjustment.
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 (F, Fig 10) and lock the
saw with the on/off valve (G).

The cutting of thin-walled workpieces
(profiles, tubes etc.) requires slow
feeding to avoid excessive wear of
sawblade.
7.7 Vice adjustment
Use the handle (A, Fig 11) to open
and close the vice for clamping.
For quick adjustment move the rack
block (B) to the desired location and
engage the rack.

The vice can be adjusted for square
and mitre cuts.
Loosen bolts and move fixed vise jaw
(C) to the desired angle.
Loosen the hex cap bolt (D) and
adjust movable vice jaw parallel to the
fixed jaw.
Always check the vice setup with a
combination square against the blade
