Release Of Locked Knife - Horizon Fitness APC-61 Manual

3-9 Release of Locked Knife

Cause for knife locking
Screw
Washer
Knife
Clamp is at right back of the knife holder.
When knife is fixed with screw without washer
by replacement, the tip of the screw hits on the
clamp. Especially,the left most screw disap-
pears behind the bridge as the knife lifts, the
problem is difficult to find.
For S/N 103001 or above, the screw is
changed so that washer does not come out
from screw. For the machines before, we
recommend you to replace the screw with a
new set of the washer M013192-10 and screw
M013397-00.
