This PTO-powered version „ZWK 790-2“ is an excellent machine with
inbuilt hydraulic system and PTO drive suitable both for firewood pre-
paration directly in the forest/wood (by simply powering it off your
tractor via a cardan shaft) and for stationary use in your yard.
A rugged all-steel construction assures longest machine life at any
operative condition.
This machine is specially designed to work with a 750 mm blade
approved and manufactured to EN 847-1.
When you switch the machine on make sure to check that the blade is
mounted to rotate in the proper direction before cutting any material.
The tool must rotate against the operator that is upward toward the
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
phase changing ask a licensed electrician to reset the saw cord.
Load the log in the carriage and smoothly push it to the blade.
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 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
with cutting. Excessive hold-down pressure may slow the blade down
and cause dangerous jamming!
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 trough by the entire length with no projecting end. After
the first log is cut off the timber, let the carriage swing down to start-po-
sition (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 reaches back to start position, you may run the
risk of hitting the stock against the blade guard consequently causing se-
vere personal injuries and machine damages for which the manufacturer
carries no liability.
The ZWK790-2 model is provided with a PTO power arrangement. A PTO
shaft is an efficient means of transferring mechanical power between farm
tractors and implements. This makes the ZWK 790-2 model an ideal pi-
ece of equipment for those who want to process their timber in the forest
producing clean logs directly on the felling site with great savings in terms
of later cleaning and disposal of wood chips, bark and sawdust.
