Strictly perform installation, set-up, maintenance, cleaning
and transportation with the motor switched off and the blade
firmly secured against accidental operation. Immediately dis-
connect power off the machine in case of any eventual fault or
trouble.
The user shall strictly comply with these operation, set-up, mainte-
nance, repair and trouble-shooting instructions in order to assure safe
operation and no damages to the equipment. Moreover, we recom-
mend to let the machine be run only and strictly by trained and skilled
staff who must be familiar with the applicable occupational safety and
health administration rules as well as applicable transportation and traf-
fic rules. Incorrect use of the saw can cause serious injury or death.
No person under school leaving age of 18 should operate a circular
saw. However, young people in age of 16 or slightly more may work
on the machine providing that they received adequate training, that
they carry all due personal protection safeties and that an adult su-
pervisor keeps standing nearby. Machine instability can result in injury
or severe damages. To ensure stability during operation make sure to
choose a flat, dry floor free from any tall grass, brush or other inter-
ferences.
The working area around the machine must be kept as clear as pos-
sible from surrounding tripping obstacles and slippery foundation
floors should be duly treated (do not use saw dust or wood ash for
this purpose).
Make sure that the equipment stands on a safe stable foundation.
Do not allow within the hazardous zone any unauthorized third or per-
sons who are not familiar with the dangers related to use and opera-
tion of the machine. Allow no bystanders, especially children and pets
in the working area.
● Due and proper illumination of the working site must be provided at all times.
● The saw blade must be duly sharpened for maximum performance and
no recoil danger. Flash and chips must be removed off the crown wheel.
● Damaged or buckled blades (very likely to break during operation)
should not be used.
● Always have the electrical system of your saw be inspected and ser-
viced strictly and only by licensed electricians.
● Always wear suitable hearing (ear plugs or muffs) and eye protec-
tion (goggles or safety glasses) while operating the machine.
● Set up the machine on a firm surface which is free from stumps,
boulders and other obstructions.
4. SAFETY

9
● Operators must wear steel toe safety shoes and snug-fitting, tear-re-
sistant work cloths.
● No additional customised protections or tools are provided on board of the
machine, other than the ones designed and supplied by the manufacturer.
● Do not apply pressure (for instance by means of the wood stock)
against the blade to make it come to a quicker stop.
● The machine is not designed for indoor use (dust release).
● NEVER leave the machine unattended with the running motor.
● Before leaving the operator‘s station for any reason, stop the machine mo-
tor, disconnect power and secure the machine against accidental operation.
4.1 Safety rules about saw blade
The unit is strictly designed for use with 600 or 700 mm (outer diame-
ter) blades.
The blade (Cr) is capable to withstand a maximum number of revoluti-
ons of 3000 rev. per minute.
Strictly use blades as per EN Standard 847-1.
Do not ever use worn out blades in need of sharpening.
Make sure that the blade shows good conditions, no damages, no
cracks, no buckling and no missing/broken teeth/bits.
Hard metal blades require special care and handling. Make sure that the
blade bits do not ever hit against hard surfaces (for example concrete floors) ,
which might cause invisible bits damage. Hard metal blades must be sui-
table to operate at a maximum speed of 2700 revolutions per minute.
4.2 Mandatory application field
These log-cutting saws are strictly designed for cutting firewood chunks
loaded on the special log carriage. All other applications are forbidden
and considered as “misuse”.
The manufacturer is not liable for any damage or injury resulting from
misuse! The machine is available in two versions SPESSART 602(603)
and SPESSART 701 respectively capable to handle wood stocks in diame-
ter of 8 up to approximately 19.5 cm (24 cm). The larger 701 model is
capable to handle logs up to a max diameter of 27cm in two cuts (turn
the log around after first cut). Shrubs and tiny branches bundles must be
loaded on the carriage and securely hold on both sides of the blade.
The machine is strictly conceived for ONE-MAN OPERATION ONLY.
Lack of compliance with these instructions may lead to
dangerous risks and situations and
in which case the manufacturer will not be responsible for
customers’ claims or resulting damages and/or injuries.

This log-cutting saw model „Spessart Woody 603/701“ is specifically
recommended for stationary use in your yard.
A rugged all-steel construction assures longest machine life at nearly
any operative condition.
This machine is specially designed to work with a 600 and 700 mm
blade approved and manufactured to EN 847-1 respectively for the
603 and 701 version.
Both versions are powered by inbuilt electric motor with inbuilt elec-
tronic braking system.
Plug your machine to an EC-approved 16 Amp power socket.
An electrical power cord for providing low-voltage alternating current
outputs from a high-voltage alternating current source is required for
230V saw versions. The cord section must be of at least 2.5 mm (cord
standard coding: 3x2,5) and it should not exceed a max length of 10
metres. A switch-plug combination outlet provides power supply to
the machine.
Have a skilled electrician connect and branch the machine for the first time.
When you switch the machine on, make sure to check that the blade
is mounted to rotate in the proper direction before cutting any materi-
al. The tool must rotate against the operator that is upward toward
operator. If not, immediately switch the polarity in the plug of main
power cord using a phase changer. If you don’t feel familiar with pha-
se changing ask a licensed electrician to reset the saw cord.
Load the log in the carriage and smoothly push to the blade.
If you working with twisted or crooked logs make sure to load
the log on the carriage, so that the bulged side of the log is
turned to the blade in order to avoid the log from tipping over
or jamming during cutting and consequent possible, even ma-
jor damages to the blade.
Now fasten the grip on the log carriage and push to smoothly tilt it
over towards and through the blade.
NOTE: avoid excessive pressure on the carriage through the blade
while cutting. Excessive hold-down pressure may slow the blade down
and cause dangerous jamming!
Now fasten the grip on the log trough and push to smoothly tilt it over
towards and through the blade. When doing so avoid all jerky, bumpy
movements that could lead to risky and dangerous situations. Timber
in maximum length of 1.1 m must lay on the carriage by the entire

length with no projecting end. After the fi rst log is cut off the timber,
let the carriage swing down to start-position (wide opened) before ad-
vancing the remaining timber to the blade and starting a new sawing
cycle. If you try to feed the stock forward and cut before the carria-
ge reaches back to start position, you may run the risk of hitting the
stock against the blade guard consequently causing severe personal
injuries and machine damages for which the manufacturer carries
no liability. Spessart 603 and 701 models are provided with an inbu-
ilt electronic braking arrangement permitting the blade to come to a
complete stop within a max lag-time of 10 seconds after switching the
motor off. Generation of a humming noise after the blade has come to
a complete stop is fully normal and due to trouble-less motor operati-
on. Do not ever restart the saw before the blade has come to comple-
te stop after it was switched off. The machine is designed for a max
number of 10 ON/OFF cycles per hour to avoid damages to electronic
braking system.
Switch the motor off and wait for the blade to come to a complete
stop before unplugging the saw from your power supply.
DO NOT OPERATE THE MACHINE if the electronic braking sys-
tem is out of order.

to secure the blade fl ange on the motor side as you undo the nut
● Remove the clamping fl ange.
● Pull the old blade off the shaft (make sure to wear tear-resistant
gloves. DANGER!) and take it out through the top.
● Fit the new blade on the shaft. Note direction of rotation. All tools must al-
ways work against the feed direction that is revolutions must occur towards
the operator’s station (see fi g. 3).
● Mount the locking fl ange back on the blade shaft minding the right posi-
tion of the feather-key in the fl ange.
● Tighten the shaft nut to hold the fl ange securely in place! ATTENTION

7. TRANSPORT
Log & timber cutting saws are light equipment that can be easily moved on
short-distance by means of two wheels and an ergonomic, comfortable grip
handle located on the chassis on the opposite side as the log carriage. In or-
der to avoid infringement of the clearance area around the machine, the grip
handle is retractable (push/pull) on both versions Spessart 601 and 701.
Simply fasten the grip and lift the saw for safe and rapid hauling of the
machine. For safety reasons the grip handle should remain retracted
(or lifted-up) during work to avoid risk of tripping or entanglement.
8. DISPOSAL
When the machine is fully obsolete and cannot be of any longer use, it should
be duly dismounted ahead of discarding. Certain components need deactiva-
tion and dismantling in order to assure that no further use is made by other
parties and that no worn out parts are recycled for other applications. During
dismantle be alert for possible recyclable materials and components that be-
long to differentiated waste collection procedures applicable in your country.
The manufacturer is not liable and undertakes no responsibility for personal
injuries or damages that may result from the recycling of worn out machine
parts and eventual re-use in other applications different than originally sta-
ted in this manual.

9. TECHNICAL DATA
Dismantling procedure:
Take good note please: each and every dismantling task must be per-
formed by authorized service centres or trained skilled staff only!
● Pull the machine down into single components, lock and clamp all
moving machine parts
● Deliver each single component only to authorized waste management facilities
● Remove rubber and plastic parts from the machine that must be
separately disposed
Deactivated, clamped moving/driving parts and components are of no
further risk and danger.
Electric components must be separately disposed to avoid substantial environ-
mental threat. In the event of fire on the electric deployment system of the ma-
chine, use of an explosion-proof extinguish system is required (for example pow-
der fire extinguishers).

9.1 Noise emissions
The noise level was measured in compliance with the general rules for
establishment of noise and acoustic pollution of garden and agricultu-
ral equipment on work sites as well as with other national standards
for noise measurement.
The applicable measuring parameters were:
Measurement on the machine front edge at 1600 mm height and
400mm away from the blade on the right hand side, while processing
beech wood in the size of 80+/-5% of the admissible timber diameter
as per this instruction:
Idle (no load) Max load/speed
Spessart 603 82 db(A) 96 db(A)
Spessart 701 82 db(A) 96 db(A)
Use of ears protectors is mandatory!
The above mentioned values are emission measurements and may not
be therefore assumed as for a safe work environment. Although there
is a relationship between noise emission and immission levels, this is
not a sufficient basis to determine the extent of on-site required pro-
tection. There are a lot of other factors that can influence site work
and risk of injuries and namely: the actual site/buildings configura-
tion, the concomitant presence of other noise sources (for instance
other machines performing other works in the neighbourhood) etc...
The factors applied for determining safety of a workplace may also ve-
ry from one country to the other. We are reporting here the noise va-
lues detected in the facility of the manufacturer on order to allow the
user performing a better evaluation of the possible risk/disturbance.

16
9.2 Electric deployment system
BEWARE: only let expert skilled staff do electric repair/mainte-
nance works!
As for all electric tools and equipment we strongly recommend use of
a portable residual current device (PRCD), unless you already have a
residual current device (RCD) in your house assuring safety and pro-
tection up to max 0.03A nominal fault current.
