Bar and chain mounting
• Mount the housing. Double check you introduce the chain tension pin. Hand tighten the mounting nuts (H) so that the
bar can move freely forward and backward until the chain tension pin fits into the bar lower orifice ( I ).

Chain Tensioning
• Use a flat screwdriver to turn the chain tension
screw (1) until the chain gets adjusted to the bar
without any looseness and with the traction links
inserted in the bar slot.
• Lift the cutting bar nose to verify if there is still some
looseness in the chain. If that is the case, turn again the
tension screw 1/2 turn. Repeat the procedure until there
is no looseness between the chain and the bar.
• Keep the cutting bar nose risen while tightening the
nuts with the key.
• To verify the chain is not too tight try moving it with
your hand. If the chain gets stuck or is difficult to move
loosen the mounting nuts again and turn the tension
screw only 1/4 of a turn. Lift the bar nose and tighten
the mounting nuts before checking back the chain
tension.
F
I
• To check the tension in the chain when heat produced
while cutting has distended it, the flat nose of the
combination key shall be inserted between the bar
lower side and one of the chain link to verify the
looseness is 0,05" (2).
