could be injured and/or workpiece could
be damaged.
5.3 Mains connection
Mains connection and any extension cords
used must comply with applicable
regulations.
The mains voltage must comply with the
information on the machine licence plate.
The mains connection must have a 10 A

5.4 Dust connection
Before initial operation, the machine must
be connected to a dust extractor. The
suction should switch on automatically
when the bandsaw is switched on. ( Fig 9)
Fig 9
5.5 Starting operation
You can start the machine with the green
on button.
The machine lamp starts automatically
when the motor is turned on.
The red button on the main switch stops
the machine.
6. Machine operation
Correct working position:
In front of the machine standing in the
direction of cutting.
Workpiece handling:
Hands placed flat on the workpiece
outside the cutting area.
Feed the workpiece towards the saw
blade in the direction of the saw line, and
cut as required by turning to follow the
line drawn.
Push the workpiece steadily forward;
complete the cut as a single movement.
Do not draw the workpiece back, as this
could cause the sawblade to run off its
wheels.
Support long and wide workpieces with
helping roller stands.
Operating hints:
Work only with a sharp and flawless
sawblade.
Near the cutting area use a push stick to
feed.
Use a feeding template to safely guide
small and narrow workpieces.
Use a suitable wedge to prevent round
timber from turning under the pressure of
the cut

7. Setup and adjustments
General note:
Setup and adjustment work may only be
carried out after the machine is
protected against accidental starting by
pulling the mains plug.
7.1 Changing the sawblade
The sawblade has to meet the technical
specification.
Choose a suitable sawblade, according to
the cutting operation and according to the
material to be cut.
For high rip cuts:
- use a wide sawblade (e.g. 10mm), coarse
teethed.
For narrow curved cuts:
- use a narrow sawblade (e.g. 3mm).
Check sawblade for flaws (cracks, broken
teeth, bending) before installation. Do not
use faulty sawblades.
The sawblade teeth must point in cutting
direction (down)
Always wear suitable gloves when
handling sawblades.
The sawblades may only be changed when
the mains plug is pulled!
7.2 Folding the saw blade
Hold the bandsaw blade in one hand. Let
it hang down vertically and hold it to the
floor with a foot. Turn your hand through
360°(a complete circle), as you move it
down towards the floor.
7.3 Blade tracking adjustment
Blade tracking shall never be performed
when the machine is running.
- Disconnect band saw from power
source.
- To check the blade tracking, rotate drive
wheel by hand in clockwise direction.
View blade through tracking window.
- Proper tracking is achieved when driver
and idler wheels are aligned. Tracking
knob on the back of the tool frame is used
to tilt upper wheel and align blade wheels.
- If blade rides away from cabinet, turn
knob clockwise. If blade rides toward
cabinet, turn knob counterclockwise.
- When blade is tracking properly, secure
position by tightening nut.
Refer to Fig10 and Fig 13.
7.4 Blade guide adjustment
Blade guide adjustment shall never be
performed when the machine is running.
Open the wheel cover.
Remove the sawblade cover from the
upper blade guide.

7
Fig 10
Upper blade guide :
- Upper blade guides employ guide pins
for side support and a ball bearing for rear
support.
- Loosen screws and adjust guide pins to
sides of the blade (see Fig 10 & 11). Use a
feeler gauge to check that guide pins are
0.05mm away from blade.
- Lock adjustment by tightening screw.
- Adjust ball bearing at rear of blade by
loosening socket head bolt and
repositioning shaft (see Fig 12).
Fig 11
- Position ball bearing 0.05mm away from
back of blade.
- Secure position of bearing by tightening
socket head bolt.
- Adjust the height of upper guide to clear
the workpiece by 6mm. Loosen upper
guide knob and adjust height of upper
guide until it clears workpiece by 6mm.
Tighten upper guide knob.
Fig 12
Lower blade guide :
- Lower blade guides employ guide pins
for side support and bearing for rear
support.
- Loosen screws (see Fig 13) and move
guide pins away from blade sides.
- Loosen socket head bolts and adjust
lower guide bracket position so that rear
of blade is positioned 0.05mm away from
bearing.
- Tighten socket head bolts.
- Adjust guide pins to sides of the blade.
Use a feeler gauge to check that guide
pins are 0.05mm away from blade.
- Lock adjustment by tightening screws.
Fig 13
7.5 Mitre gauge setup
Setup adjustments shall never be
performed when the machine is running.
Use a gauge to exactly set up for 90°
Adjust the mitre gauge profile to be close
to the sawblade.
Start the machine with care.
7.6 Tilting of machine table
The table tilts from 0°to 45°to the right.
- Turn the table tilt lock lever
counterclockwise.
- Turn the table tilt adjustment knob until
the pointer is at the desired angle on the
table tilt gauge.
- Tighten the table tilt locking knob in
order to secure the table. ( Fig 14).
Fig 14
Test run:
Turn the wheels by hand and inspect the
adjustments made.
Start the machine with care.
Workpiece setup:
Bring the upper blade guide to a distance
of approx 0,5cm to the workpiece (Fig 15).
Fig 15
For your own safety, always set the saw
guide as close to the workpiece as
possible.
