BACKLAPPING
The keen edges of the spiral cutters can be
maintained by backlapping. With the units in the
lowered position proceed as follows:
1.
Smear the edges of the spiral cutters with a
medium grade of carborundum paste.*
2.
Lift seat and move cutting cylinder direction
control valve lever toward the front of the machine
to enable reverse rotation. Lower seat to original
position.
3.
Ensure that the parking brake is applied.
4.
Sit in the driving seat and start the engine.
5.
Set the throttle control lever to give minimum
engine speed.
6.
To engage cylinder drive activate rocker
switch on console and depress foot switch.
7.
Continue to run for a few minutes then stop the
engine to check and adjust the cutting cylinder to
the bottom blade.
8.
If the cylinders require further backlapping,
repeat operations 3,4,5,and 6 until the edges are
completely sharp.
9.
Once procedure is complete stop the engine and
lift seat. Return cutting cylinder direction control
valve lever toward rear of the machine for normal
cutting rotation.
*Obtainable from most motor accessory shops or
garages.
NOTE: Even badly dulled edges are usually
resharpened after 10 minutes treatment.
After backlapping is completed, clean off all traces of
carborundum paste from the bottom blades and spiral
cutters. It is essential that this is done thoroughly
otherwise the cutting cylinders and bottom blades will
quickly lose their effectiveness when they are rotating
normally for grass cutting.
