Changing the Planer Knives
Switch off the machine during maintenance and repair work and secure it against being
switched on again unexpectedly! Lock the main switch with a padlock!
Even when stationary, cuts from the knives are possible!
Always wear protective gloves when changing the knives!
12.1
Changing the TERSA Knives on an All-Steel Cutter Block (standard)
Only use original replacement planing knives from the manufacturer. The blades must always be the same
length as the maximum planer width (Version 334 = 410 mm / Version 335 = 510 mm / Version 336 = 630 mm).
•
Knock back the pressure bar segments using a hammer in
combination with the brass wedge (
3
) included in the delivery
or a piece of wood. Please do not use a screwdriver or similar
made of steel, otherwise the blades will be damaged!
•
Pull out the knife (
1
) sideways
Turn the knife resp. replace and reinsert it.
•
The knives are automatically tensioned to the correct flight
circle by the centrifugal force acting on the pressure bars (
2
).
•
To ensure absolute clamping of the knives after changing the
knives, an initial planing with hardwood over the entire planing
width is necessary.
Suitable replacement knives for your Tersa cutter can be found
