Remove the side plate on the right side of the machine (4x m8 bolts)
using a 13 mm ratchet spanner.
Remove the two bolts securing the spring mounting rail to the left side
of the machine housing. You can then remove the side plate and spring
mounting rail together as one unit. Remove the springs from the
notches on the swing arm.
Lift and rotate the cutting reel out of the machine, resting it carefully
on the folded edges of the housing. From this angle, you can see the
condition of the base blade more clearly. To take the base blade off the
machine, undo the bearing on the right side of the roller (using 2x
13mm spanners) then undo the four m10 countersunk bolts using a 6
mm Allen key.
To remove the reel, remove 4x m10 bolts holding it in place from both
sides of the reel (requires a 16 mm socket plus extension). Once
removed, loosen the grub screws in the bearings (requires a on both
sides of the reel shaft, then slide them off. When replacing these bolts,
ensure they are done up with spring washers and
torque the bolts to
44 Nm
.
Sharpening the base blade
Sharpen the base blade on a surface grinder. A cutting angle of 2.5 ° (relative to the inside flat face of the base blade) is critical for
the performance of the cutting mechanism. Make sure plenty of coolant is used when grinding to avoid softening of the base blade.
If you don’t have a surface grinder or are unsure how to re
-sharpen the base blade, contact a professional saw doctor or Hansa to
arrange re-sharpening.
Cutting mechanism checking/adjustment
Over time, or after sharpening, the base blade on the machine will wear down resulting in material being cut more coarsely or not
being cut at all. It is recommended that every 50 hours, or as required, the position of the cutting reel be adjusted. To adjust the
cutting reel position, follow the steps below:
