Make sure to refi t the V-belt casing back in place before operating the
machine again.
7.5 Lubricating the blade shaft bearings
If you are using a „WK 700Z Classic“ model, make sure to provide peri-
odical lubrication of the blade shaft after each 100 hours of operation.
Remove both cover plates on the safety guard over the blade shaft
and use a regular greasing gun to perform bearings lubrication. Provi-
de lubrication by means of a greasing nipple. Make sure to refi t both
cover plates before working again.
7.6 Replacing the saw blade
Safety note ! Wear safety gloves - pinched hands danger.
Before replacing the blade make sure to disconnect the machi-
ne from power (unplug the electric motor or turn the tractor
off).
To replace the blade, following precautions must be taken at all times:
● 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 and removing the 4
hex-screws with hex-nuts.
● Release and undo the fi xation bolt on the blade clamping fl ange
using a spanner and hold the blade using another spanner 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!)
● 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 4)
● Mount the locking fl ange back on the blade shaft minding the right
position of the feather-key in the fl ange.
● Tighten fi xation bolt with nut on the fl ange.
● Refi t the blade hood in the original position duly set and clamped.
● Now the saw is ready to operate again.
WARNING: Do not regrind worn out blades if the tips do not
show above bench level when the blade is in the resting positi-
on. In this case old blades must be replaced.
