• Saw blade is dangerous.
Be sure to wear gloves when handling saw blade in situations
such as removing from packaging, mounting or replacing blade.
1.
Loosen the two thumb screws for the right-guide rail, and slide
the right-side rail to the right. (Fig. 23)
2.
Open the upper cover and lower cover on the tool. (Fig. 24)
3.
Hold the handle and pull the dust cover upwards to remove.
(Fig. 25)
4.
Open the lower blade guard. (Fig. 27)
5.
Set the upper blade guide to its lowest position. (Fig. 26)
6.
Loosen quick release lever until the band saw blade has
slackened. (Fig. 28)
7.
To remove the band saw blade, guide it through.
- the slot in the saw blade.
- the blade guard on the upper blade guides.
- the blade cover on the saw housing.
8.
Fit a fresh band saw blade. Observe correct position: the teeth
point towards the front (door) side of the saw.
9.
Center band saw blade on the rubber tyres of the band saw
wheels.
10. Tighten quick release lever until blade does no longer slip off
the band saw wheels.
11. Close lower blade guard.
CAUTION:
Close lower cover only when the lower blade guard is in its closed
position.
12. Return the right-guide rail to its original position.
13. Fit the dust cover. (Fig. 29)
14. Close both covers.
15. Then:
- tension band saw blade (Refer to the section titled
"Tensioning the band saw blade" in "FUNCTIONAL
DESCRIPTION").
- align band saw blade (Refer to the section titled "Aligning the
band saw blade" "ASSEMBLY").
- align blade guides (Refer to the section titled "Adjusting the
upper blade guide" in "FUNCTIONAL DESCRIPTION").
- let saw test run for at least one minute;
- stop saw unplug and recheck settings.
Cutting speed adjustment (Fig. 30)
1.
Open the lower cover.
2.
Slacken driving belt by turning the knob clockwise.
3.
Put driving belt on the required pulley of the driving wheel
(lower band saw wheel) and the corresponding motor pulley-
note label inside the lower cover.
CAUTION:
The driving belt must run either on both front or both rear pulleys.
Never have the V-belt run diagonally.
Setting knob for belt tension (Fig. 31)
With the setting knob the belt tension is corrected if necessary:
- turning the setting knob clockwise reduces the driving belt
tension.
- turning the setting knob counter-clockwise increases the driving
belt tension.
Tighten the driving belt again by turning the knob counter-clockwise
(half-way between the pulleys the driving belt should flex
approx. 10 mm). (Fig. 32)
Close the lower cover.

FUNCTIONAL DESCRIPTION
Tensioning the Band saw Blade (Fig. 33)
CAUTION:
Too much tension can cause the band saw blade to break. Too
little tension can cause the driven band saw wheel to slip and
the band saw blade to stop.
1. Raise upper blade guide fully.
Using the scale as guide, and taking the blade width into
consideration, turn the knob to adjust tension. (After adjusting,
check tension as shown in item 2.)
2. Checking the blade tension:
- check tension by pushing with a finger, halfway between
table and upper blade guide, against the side of the blade
(the blade should flex not more than 1-2 mm).
- check adjustment at the blade tension indicator. The scale
indicates the correct adjustment in dependence on the band
saw blade width.
3. Correct tension if necessary:
- turning the setting knob clockwise increases the blade
tension.
- turning the setting knob counter-clockwise reduces the blade
tension.
Aligning the band saw blade (Fig. 34)
If the band saw blade does not run in the center of the rubber tyres,
the tracking needs to be corrected by adjusting the tilt of the upper
band saw wheel:
1. Loosen lock knob.
2. Manually rotate the upper wheel, taking care not to touch the
blade. (Fig. 35)
3. Turn setting knob clockwise if the band saw blade runs towards
the front of the saw.
- turn setting knob counter-clockwise if the band saw blade
runs toward the rear of the saw.
4. After adjusting, always close the lock knob.
Quick release lever (Fig. 36)
With the quick release lever the saw blade tension is released.
Clockwise: Reduce tension
Counterclockwise: Increase tension
Upper blade guide adjustment (Fig. 37)
The height of the upper blade guide needs to be adjusted:
prior to every cutting/operation, to accommodate the height of the
work piece (the upper blade guide should be set approx. 3 mm
above the work piece);
- after adjustments of band saw blade or saw table (e.g. band saw
blade change, tensioning of the band saw blade, saw table
alignment).
CAUTION:
Before adjusting the upper blade guide and saw table tilt:
- switch machine OFF;
- wait until the band saw blade has come to a complete stop.
• Set upper blade guide with the adjusting knob to the desired
height by loosening the lock knob.
After adjustment be sure to tighten the lock nut.
• Never cut several work pieces at the same time — and also no
bundles containing several individual pieces. Risk of personal
injury if individual pieces are caught by the saw blade
uncontrolled.
