DESCRIPTION
Sharpener
The sharpener consists of the following parts:
• A fixed section.
• Sharpener motor.
• Feed mechanism.
The fixed section houses a motor for the
bandsaw blade feed and three folding support
arms, which form a stable platform for the
sharpener set-up. The support arms also secure
the bandsaw blade while grinding.
The moving section houses the motor, the
grinding disc, and arms for its suspension. The
moving section can be adjusted to grind three
different cutting angles: 7°, 10°, and 14°.
The feed mechanism consists of a cam disc and
levers. The cam disc is driven by the feed motor
on the fixed section. The cam disc actuates the
two levers, which in part feed the bandsaw blade
forwards and in part lower and lift the grinding
disc while grinding.

MAINTENANCE
Bandsaw Blade
The bandsaw blade should be set and
sharpened regularly to give optimal performance.
During normal sawing of most species of wood
this should be done at intervals of approx. 2
hours of effective cutting time. Effective cutting
time only refers to the time that the bandsaw
blade actually works. The bandsaw blade should
be sharpened more frequently when cutting
those species of wood with a high sand content.
Cleaning and Inspection
Clean sawdust and any coating from the
bandsaw blade.
Check whether there are any cracks in the
gullets (See Fig. 1. A). Small cracks can be
ground away when sharpening the bandsaw
blade. If the cracks are so large that they cannot
be ground away, the bandsaw blade should be
discarded.
Cracks in the gullets (A) are the most common
cause of bandsaw blade breakage.
WARNING!
The bandsaw blade is sharp
and can cause injury. Wear
protective gloves whenever you
handle the bandsaw blade.
WARNING!
Never use a damaged bandsaw
blade.
FIG 1

MAINTENANCE
Sharpening
The more accurate the sharpening, the straighter
and smoother the bandsaw blade runs when
cutting the log.
Radii
The radius in the area (A) (Fig 2) should be 1- 3
mm.
• A radius under 1 mm increases the risk of
cracking.
• A radius over 3 mm means that the chips are
not broken.
Angles
The clearance angle should be 10-12° (see Fig
3) and the cutting angle (F) (see Fig 4) varies
depending on the species of wood as follows:
WARNING!
The bandsaw blade is sharp and
can cause injury. Wear protective
gloves whenever you handle the
bandsaw blade.
Hardwoods or frozen timber
Medium hardwoods
Softwoods

MAINTENANCE
Setting Up the Sharpener
Place the sharpener on a level and sturdy
surface.
Connect the cables to a 12-volt power source.
The power source can be a battery or a battery
charger.
The red cable is connected to + and the black to
-. If the cables are interchanged, the grinding disc and
feed motor will run in the wrong direction.
Sharpening with the Sharpener
The sharpener can be used on bandsaw blades
with a pitch of ¾” – 1” (19 – 32mm). The grinding
disc may need to be redressed for other tooth
profiles.
1. Loosen the knob (43) and set the correct cut-
ting angle (F). See Fig. 5.
2. Tighten the knob (43).
3. Check that the grinding disc has the correct-
profile. Use the metal profile tool that was
provided.
CAUTION! A new grinding disc must be
shaped before use. Use the supplied
whetstone (52).
4. Fold up the grinding motor (45), hold up the-
feed link (H), and insert the bandsaw blade.
The bandsaw blade should lie in the cut-outs
in the support arms.
5. Check that the bandsaw blade rests on the
two supports. The support arms can be
bent if the bandsaw blade does not lie
against both the supports.
6. Adjust the bolt (J) so that the bandsaw blade
runs freely and at the same time is held
securely.
WARNING!
The bandsaw blade is sharp
and can cause injury. Wear
protective gloves whenever
you handle the bandsaw
blade!
WARNING!
Do not store gasoline/petrol in the
vicinity of the sharpener. Sparks
from the grinding disc or the
electrical connection can ignite.

MAINTENANCE
7. Start the feed with the power switch (49). The
feed cam wheel (K) should rotate counter
clockwise. If this is not the case, the
connection cables have been interchanged.
8. Stop the feed and check where the grinding-
disc goes down against the bandsaw blade.
9. Adjust the knob (L) until the grinding disc
just touches the inside of the saw tooth (M).
Points 7 and 8 above may need to be
repeated.
10. Insert the lifter (N) in the appropriate hole in
the lever (O) and start the feed. Adjust the
knob (P) until the grinding disc just touches
the entire tooth valley while fed.
11. Install the aluminum plate on the sharpener
as shown in Fig. 11. Note that it is slotted
so that it can be moved left or right. Doing
this will adjust the profile or sweep that the
grinding wheel follows.
12. Stop the feed and turn both knobs 1/2 turn
counter clockwise.
CAUTION! Do not grind to heavily. This can
destroy the hardening of the teeth. Each
turn of the adjuster screws corresponds to
a grinding depth of 0.75 mm. The maximum
grinding depth per sharpening is 0.1-0.2
mm. If the bandsaw blade is very worn, grind
several times.
WARNING!
Risk of damaging the grinding
disc or bandsaw blade, can
result in personal injury. The
grinding disc must not be
running during the procedure
set out in points 8-11 below.
WARNING!
Risk of the grinding disc
coming loose and causing
personal injury. Ensure the
power supply is connected so
that the grinding disc rotates in
the right direction, that is,
sharpening is performed
downwards / backwards.

MAINTENANCE
WARNING!
Check that the grinding disc
shows no signs of cracking and
that it is secured to the spindle.
Stop the grinding disc
immediately if abnormal
vibrations occur.
WARNING!
Wear protective glasses while
grinding!
1. Fit the stop plate (Q).
2. Start the grinding disc and feed using the
power switches (49 and 50).
3. When the sharpener stops automatically,
re- move the stop plate.
4. Fold up the grinding motor and remove the
bandsaw blade.
Changing the Grinding Disc
1. Fold up the top section of the sharpener.
2. Hold the grinding disc and loosen the nut (R)
using a pair of pliers.
3. Remove the old grinding disc and fit the
new disc. Tighten the nut (R) lightly using
a pair of pliers.
FIG 11
WARNING!
Before changing the grinding
disc, disconnect the power
supply to the sharpener!
