4. SAFETY RULES

9
● 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 engi-
ne, disconnect power and secure the machine against accidental
operation.
4.1 Safety rules about saw blade
The unit is strictly designed for use with a 600mm (outer diameter)
blade. The blade (Cr) is capable to withstand a maximum number of
revolutions 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 conc-
rete floors), which might cause invisible bits damage.
Hard metal blades must be suitable to operate at 3250 revolutions per
minute.
4.2 Mandatory application field
These log-cutting saws are strictly designed for preparation of fire-
wood. Sawing to be strictly performed with wood stock on the log car-
riage. 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 capable to handle wood stocks in diameter of 8-19.5
cm. Shrubs and tiny branches bundles must be loaded on the trough
and securely hold on both sides of the blade.
The machine is strictly conceived for ONE-MAN OPERATION
ONLY.
Check the tension of the V-belt before first use!
Misuse will completely void your warranty. The manufacturer
accepts no liability for personal injuries and damages to other
equipment caused by misusing the machine.

5. OPERATION
This log-cutting saw model WK 600 B Classic is ideally recommended
for stationary use in your yard.
A rugged all-steel construction assures longest machine life at any
operative condition.
This machine is equipped with inbuilt gasoline engine for independent
power provision. Please read the instructions of the engine ma-
nufacturer before use.
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 the
operator. Load the log in the carriage and smoothly push to the blade.
Make sure to avoid inhaling gasoline vapors during use.
If you working with twisted or crooked logs make sure to load the
log on the carriage, so that the bolged 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 major 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 with cutting. Excessive hold-down pressure may slow the
blade down and cause dangerous jamming!
When pushing the log through the blade doing so avoid all jerky, bum-
py movements that could lead to risky and dangerous situations. Tim-
ber in maximum diameter of 200mm and length of 1.1 m must lay on
the carriage by the entire length with no projecting end.
After the first log is cut off the timber, let the carraige swing down to
start-position (wide opened) before advancing the remaining timber to
the blade and starting a new sawing cycle.
If you try to feed the stock forward and cut before the carriage rea-
ches 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.
If the maximum 16 mm spacing between clearance inserts (wood
strips) is reduced because of excessive wear, provide for immediate
replacement of the wooden inserts! (see Figure 1)

6. REPAIRS AND MAINTENANCE
Make sure that the machine is fully disconnected and all mo-
ving parts are secured before performing any maintenance/re-
pair work on the machine. In the event of any malfunctioning,
switch the machine off before trouble-shooting.
6.1 First maintenance after initial start-up
Check and tighten all fixation elements after 1 operation hour, in or-
der to avoid damages to the motor.
Make sure to check the torque of all fixation hardware used for the
driving pulley of the motor. Adjust torque, as necessary.
Procedure:
• Unscrew and remove the cover 2 (pos. 8 of the spare part list) over
the pulley by removing the 4 hex screws M6x16 and relative was-
hers (pos. 31, 23 see spare part list)
• Remove screw M8x25 (Pos. 41) with its spring lock (Pos. 40, of the
spare part list) and washer (Pos. 38, of the spare part list)

6.2 Ordinary maintenance
The following tasks belong to ordinary maintenance works:
● Clean the machine from eventual residual wood, chips or dirt.
● Lubricate all moving parts.
● Grease all pivoting parts of the log carriage
6.3 Cleaning after use
Remove wood chips and saw dust produced and left on the machine
during work.
Clean the log carriage assembly removing all wood rests.
6.4 Replacing the saw blade
Safety note ! Wear safety gloves - pinched hands danger!
Before replacing the blade make sure to disconnect the machine
from power (unplug the electric motor or turn the tractor off).
Following instructions apply for safe and proper blade replacement:
● Disconnect power off the machine (unplug power cord or stop the
motor of the tractor) and wait for the blade to come to a complete stop.
● Tipp the upper blade hood over by releasing the 4 screws
● Release and undo the fixation bolt on the blade clamping flange
using a spanner to secure the blade flange on the motor side as you
undo the nut (spanner SW 41).
● Remove the clamping flange.
● Pull the old blade off the shaft (make sure to wear tear-resistant
gloves. DANGER!)
● Fit the new blade on the shaft. Note direction of rotation. All tools must
always work against the feed direction that is revolutions must occur
towards the operator’s station. (see Figure 6)
● Mount the locking flange back on the blade shaft minding the right
position of the feather-key in the flange.
● Tighten fixation bolt on the flange. BEWARE: when assembling the
new blade make sure to follow the dismounting procedure: saw
blade, external saw blade clamping flange, washer, fixation screw.
● Refit the blade hood in the original position duly set and clamped.
Saw blades, where tips do not any longer show through the
slot in the log carriage with the saw in its start/posions, will
have reached the end of their regrind life and shall be taken
out of service.

6.5 Tensioning and replacing the V-belt
If you are operating a WK 600 B model, proper maintenance requires
re-tensioning of the belt after a certain number of operation
hours. To perform stretching of the V-belt, you need adjusting the
special regulation screw located underneath the gearbox cover.
Release the engine mount fixation and adjust the V-belt so that you
can still provoke an approx. 10 mm of deflection by applying one fin-
ger tip pressure (see figure 7 - Stretching of the V-belt).
Fit the gearbox cover and the engine mount back into place before
operating the machine again.
Running the saw with a loose V-belt will cause increased wear and
shorten you belt life.
To replace the belt, release the clamp-screws and remove the
safety guard from the V-belt drive area. Remove the old belts from
the sheaves and fit the new ones on.
Make sure to refit the V-belt casing back in place before operating the
machine again.
BEWARE: failure to provide due re-tensioning will result into a less ef-
ficient V-belt drive that slips and may be wear out faster
6.6 Consumables
Consumable parts that are subject to normal wear are not covered by
the manufacturer‘s warranty. These are:
Saw blade (Code 95004 for HM versions)
Wood strips (Code 54383)
V-belt (Code 56187)
Figure 7

These log & timber cutting saws are light equipment that can be
easily moved on short-distance by means of two caster wheels and
an ergonomic, comfortable grip handle located on the chassis on the
opposite side as the log carriage. In order to avoid infringement of the
clearance area around the machine, the grip handle can be swivelled
up and down on the model WK 600B.
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.
7. HANDLING AND TRANSPORT
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 deactivation 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 compo-
nents that belong to differentiated waste collection procedures applica-
ble in your country.
The manufacturer is not liable and undertakes no responsibility for per-
sonal injuries or damages that may result from the recycling of worn
out machine parts and eventual re-use in other applications different
than originally stated in this manual.
Dismantling procedure:
Take good note please: each and every dismantling task must be per-
formed by authorized service centres or trained skilled staff only!
● Lock and secure all moving parts of the machine and pull the ma-
chine down into single components
● Deliver each single component only to authorized waste manage-
ment 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.

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. Detected noise levels:
Without load 92 db(A)
With max load 110 db(A)
Hearing protection 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 protection.
There are a lot of other factors that can influence site work and risk of
injuries and namely: the actual site/buildings configuration,
the concomitant presence of other noise sources (for instance other ma-
chines performing other works in the neighbourhood) etc... The factors
applied for determining safety of a workplace may also very
from one country to the other. We are reporting here the noise values
detected in the facility of the manufacturer on order to allow the user
performing a better evaluation of the possible risk/disturbance.
