Maintenance
WARNING! Always disconnect the machine
!
from the air hoses before inspection and/or
maintenance of the machine.
Tensioning the drive belt
The drive belt is fully enclosed and well protected from dust
and dirt.
When the drive belt is to be tensioned, release the nuts
holding the cutting arm.
Screw the adjuster screw so that the square headed nut
comes opposite the marking on the cover. This automatically
ensures that the belt has the correct tension.
Tighten the two nuts holding the cutting arm.
Replacing the drive belt
First release the nuts and then the adjuster screw to release
the belt tension.
Unscrew the nuts and lift off the front belt guard.
The cutting head is now loose and can be removed from the
machine. Remove the rear belt guard by releasing the three
screws holding the guard.
MAINTENANCE
Take off the old belt and fit the new one. Fit the cutting arm to
the machine and tension the belt with the adjuster screw. A
new drive belt should be re-tensioned after running for about
30 minutes.
Checking the drive axle and flange
washers
Check that the threads on the drive shaft are undamaged.
Check that the contact surfaces on the blade and the flange
washers are undamaged, of the correct dimension, clean,
and that they run properly on the drive axle.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange washers.
Water cooling
Check that the water tap functions. To open the water tap, turn
the tap to open position.
To turn off the water, turn the tap to closed position.
Water filter
