For refitting, proceed in reversed order. It will suffice to tighten the cutting head to hand tight with the hook
wrench.
Changing the Cutting Heads
1) Loosen cutting insert fastening bolt with torx wrench (T 10, supplied) and remove cutting inserts. Repeat
this procedure in the same way for each of the three cutting inserts.
2) Rotate or replace cutting inserts.
3) Refit cutting inserts with fastening bolt (tighten to hand tight).
There is no need to remove the cutting head when changing the cutting inserts. It will suffice to turn home
the support plate with the adjusting collar.
Changing the Ball Bearing Race
Any worn out ball bearing must be duly replaced in order to prevent the chamfer surfaces from suffering
irregular machining.
a) Loosen lower hex nut (2).
b) Pull away and replace ball bearing race.
c) Fit new ball bearing race with hex nut (2).
Replacing Carbon Brushes
With the carbon brushes worn out the motor will stall or the collector will be damaged. Have carbon brushes
checked and replaced by a specialist as necessary.
Only use genuine ALFRA carbon brushes and follow instructions on rating plate.
