With the help of another person, lift
the working table onto the trunnion.
Mount the working table to the trun-

Install the fence bar to the table with
four hex nut at two position. Locate the
fence carrier on to the fence bar. Slide
the rip fence on to the fence carrier and
tighten the holding fixtures. Screw in
the lock handle to secure the position
of the fence on the fence bar.
Attach the large crank handle (Fig. 4) to
the rack and pinion on the upper part of
the bandsaw, using the 5mm "L" wrench
provided. Attach the small crank handle
(Fig. 4) to the belt and speed control rod
on the lower right side of the bandsaw,
using the 5mm "L" wrench provided.
The table may be set at 90° to the saw
blade by adjusting the table stop screw
under the table. The table stop screw
rests on the top of the lower wheel
bandwheel housing. By fi rst slack-
ening the locking nut (A--Fig.5) and
then adjusting the screw (B--Fig.5), the
table can be set correctly. Retighten the

the desired angle. Retighten the lock
handle to secure the table.
WARNING! Unplug the bandsaw.
Firstly, make sure the upper and lower
blade guides are adjusted away from
the blade and the tension scale reading
corresponds to the width blade you are
using. Then loosen the lock lever
(Fig.7) by turning it counterclockwise
and turn the blade tracking knob (Fig.7)
clockwise/counterclock-wise while tur-

To loosen the tension of the blade, turn the
blade tension handwheel (Fig.8) counter
clockwise. To tighten the tension of the
blade, turn the blade tension handwheel.
Tension the blade until the tension readings
corresponds to the width blade you are
using through the tension indicator window
(Fig.8).
To adjust the upper blade guides, fi rst
position the roller guides relative to the
blade by slackening off the hex nut (A-
-Fig.9) and moving the guide carrier
until the roller guides are approx. 1/16"
behind the gullets of the blade. Next set
the roller guides to within 1/32" of the
blade by releasing the screw (B--Fig.9)
on each side of the blade. Do not set the
To adjust the lower blade guides, fi rst
