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.
7.1 Regular maintenance
The following tasks belong to ordinary maintenance works:
● Clean the machine from eventual residual wood, chips or dirt.
● Lubricate all moving parts.
● Lubricate the bearings beneath the blade arbour
Additional ordinary maintenance for PTO powered versions:
● Check-up and eventually stretch the V-belts, if required.
● Lubricate the bearings beneath the blade arbour
7.2 Yearly maintenance (or every 50 operation hours)
Hydraulic oil change: Oil capacity approx. 0.4 l
Oil viscosity: Class CLP/CC 150 (ISO 150) SAE 90G
7.3 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.
7.4 Tensioning and replacing the V-belt
If you are operating a WK 700Z Classic (PTO) model, proper mainte-
nance requires re-tensioning of the belt after a certain number of ope-
ration hours.
To perform stretching of the V-belt between the angular gearbox and
the blade arbour, you need adjusting the clamping bolts located bene-
ath the angular gearbox.
Adjust the V-belt so that you can still provoke an approx. 10 mm of
deflection by applying one finger tip pressure in the middle (see figure
3 - Stretching a V-belt) of the distance between sheaves middle axis.
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.
To replace the belt, release the clamp-screws and remove the safety
guard from the V-belt drive area.
Release and remove the old belts from the sheaves and fit the new
ones on.
