To Remove The Cutter Blades; To Install The Cutter Blades - Porter Cable 6605 Manual Del Usuario

HOW TO USE THE SHEAR
Firmly support and clamp the workpiece to ensure control. Position the workpiece
with the hidden or back surface of the material facing up to reduce marring of the
exposed side. To achieve maximum cutting efficiency, hold the bottom of the
stationary blades parallel to and against the workpiece.

TO REMOVE THE CUTTER BLADES

Disconnect the tool from the power source!
1. Remove the shear head from the
motor unit. Loosen the three cap
screws (A) Fig. 3. Pull the cutter
head forward to separate it from
motor unit. A light twisting motion
may be helpful.
2. Remove the three cap screws (A)
from the shear housing. Retain the
spacer bushing (C) with the middle
cap screw).
3. Remove the center blade by gently
tapping it rearward. Retain the
spacer bushing (C) removed from
the hole in the center blade.
4. The side knives (D) and (E) will drop
out of the shear housing.

TO INSTALL THE CUTTER BLADES

NOTE: Change the side knives after they show a width wear pattern of fifty
percent (50%). Swap the knives left to right and use them until the patterns meet.
When the patterns meet, invert the left and right side knives and use them until
they show a width wear pattern of fifty percent (50%). They can then be swapped
from left to right until you use all four (4) sides of the blades. Never exceed 10,000
feet of cutting on a set of side knives. The tool will continue to cut after these
landmarks are reached, but to do so will overload the power unit.
Disconnect the tool from the power source!
1. Place the side knives (D) and (E) Fig. 3 back into the shear housing. Insert a
cap screw through the center hole in the shear housing, the side knife (E),
the spacer bushing (C), the other side knife, (D). Thread the screw into the
housing one or two turns. DO NOT TIGHTEN.
2. Coat the remaining spacer bushing (C) Fig. 3 with lubricant and insert it into the
hole in the center blade (F). Start the center blade (with the spacer bushing) into
the rear of the shear housing. Tap it forward until the hole in the spacer bushing
aligns with the front hole in the shear housing. Insert a cap screw and thread it
into the housing one or two turns. DO NOT TIGHTEN. Coat the center blade
yoke area with lubricant.
3. Insert the remaining cap screw into the rear hole in the shear housing and
thread it into housing one or two turns. DO NOT TIGHTEN.
4. Place the shear head on the motor unit. Seat it with a light twisting motion.
Rotate the shear head to the desired position (any radial position), and
tighten all three cap screws (A).
5. For Model 6605, tighten all three cap screws (A) to 45-50 in-lbs. Failure to
tighten the cap screws properly can cause the cap screws (A) to break.
