Introduction
INTRODUCTION
This operator’s manual describes in detail how
the one-man sawmill is used and maintained and
how servicing is to be carried out. It also describes the measures to be taken for maximum
safety and how the safety features are designed

maintained, and repaired if necessary.
NOTE! The section dealing with safety must
be read and understood by all those who
install, use, or repair the sawmill.
The operator’s manual comprises installation,
usage, and the different maintenance procedures
that can be performed by the operator. More

should be performed by the dealer’s service
personnel.
The operator’s manual describes all the requisite
safety features and should be read and understood by the user before the sawmill is assembled.
Symbols and warning signs shown on the next
page can be found in this operator’s manual and
on the one-man sawmill. If a decal on the sawmill
has been damaged or is worn, a new warning
decal must be applied as soon as possible in
order to ensure the greatest possible safety
when using the sawmill.
The one-man sawmill shall only be used to cut
boards and planks from logs.
The one-man sawmill should be used outdoors

3. Ensure that there are no people or animals
within the one-man sawmill’s risk zone.
4. The stopping and locking devices required to
fasten the log shall be used in the intended
manner. See pages 26-28.
5. Adjust the bandsaw guide so that it is as
close to the log as possible. See page 27.
6. Adjust the scale and check that the bandsaw
moves freely over the short and long log
supports by the red markings on the scale.
See page 22.
Special safety regulations apply to the fuel used
with the one-man sawmill. These are documented
in the section Fuel Handling on page 23.

DESCRIPTION
Carriage (FIG 2)
The carriage consists of the following parts:
• Steel structure with runner wheels against
the rails and guides for the saw’s up and
down movement.
• Two screws for the saw’s vertical adjustment.
The screws are connected to a chain and are
operated by a crank, equipped with an index
plate.
• Handle with operating mechanism
• Saw unit with the following parts:
• Engine.
• Adjustable band wheels.
• Bandsaw blade.
• Adjustable support for optimal bandsaw
blade guiding.
• Fuel tank (petrol engine) for petrol. See
the Fuel Handling section.
• Cleaning fluid tank for the bandsaw blade.
• Muffler (petrol engine).
Frame (FIG. 3) and (FIG. 4)
The carriage frame consists of welded square
tubing with requisite corner reinforcement for
stability during cutting.
The frame is equipped with two round runners for
the saw unit's up and down movement. The
guides transfer the saw carriage’s lateral forces
to the frame.
FIG. 2
FIG. 3
On the underside of the frame are four runners,
fitted with bearings, with slots for securing and
smooth running along the rails.
The carriage is equipped with two adjustable
bearings, which run against the underside of the
rails, to prevent it from lifting.
Height Setting (FIG. 4)
The saw unit is secured vertically by two interacting screws. The screws are connected to a chain
for precise and simultaneous movement.
A crank (29) is fitted on the top section of one of
the screws, and is used to set the exact dimension of the timber thickness. One turn of the
crank moves the bandsaw blade 5 mm. The
height of the bandsaw blade above the rails’
cross members is read on the scale (1).
There are two red markings on the scale that
indicate the lowest saw height with the timber
support raised, one red line for the long timber
support and one red line for the short one.
CAUTION! Sawing under the respective markings will damage the bandsaw.

DESCRIPTION
Handlebars (FIG. 5)
The saw carriage is operated and moved forward with a vibration-free steering handlebar (5),
located on the carriage’s right hand side. The
handlebar is equipped with start and stop
controls (4) for the bandsaw.
Cleaning T ank (FIG. 5)
The saw carriage is equipped with a cleaning
tank (3). The tank is located beside the handlebars. Cleaning fluid is applied to the blade by
opening the tank valve.
Band Wheels (FIG 6)
The bandsaw blade runs over two band wheels
(26), which are made of cast aluminium and are
balanced to provide smooth operation. The band
wheels are equipped with bearings, and are
adjustable, partly to tension the bandsaw blade
and partly to adjust the correct alignment of the
bandsaw blade.
The band wheels are fitted with scrapers so that
sawdust and the like does not penetrate between
the bandsaw blade and the band wheel.
One of the band wheels is powered by the
engine/motor via an adjustable belt.
FIG 5
FIG 6
Bandsaw and Band Guide (FIG 6)
Two band guides (8) are used to keep the
bandsaw blade (9) in the correct position during
cutting. One of the band guides is placed in front
of the powered band wheel and ensures correct
entry onto the wheel. The other band guide is
adjustable and is positioned above the bandsaw
blade before it runs onto the log. This band guide
absorbs the forces from the log and prevents the
bandsaw blade from shifting.
Propulsion
Petrol Engine (FIG. 7)
The one-man saw is run with an air-cooled fourstroke engine (15). A clutch is located on the
engine’s drive axle that starts, stops, and brakes
the bandsaw blade. The speed of the engine is
regulated with the operating control on the
handlebars. See the enclosed manual for a
description of the engine.
Electric Motor (FIG. 8)
The one-man saw is powered by a 3-phase motor
(37). The motor is started and stopped with the
start and stop buttons on the distribution box,
which has built-in motor protection. There is also
a connection for an electric cable with single
polarity reversal (FIG. 8A), and a main switch
(FIG. 8B.). A clutch is located on the motor’s axle
and starts, stops, and brakes the bandsaw blade.
