BLADE CHANGING
• Dull blades greatly reduce cutting ability. Re-sharpen or replace as
needed.
• Proper blade size and placement per job type greatly affects
performance.
• Disconnect electrical power first.
• Do not lean machine back onto handle.
• Always wear gloves when changing blades to protect fingers and
hands.
1. Place a block under front of machine as shown in diagram, raising
blade holder (See Figure A).
2. Use extended socket wrench that comes with Panther or a socket wrench with at least a 3'' extension
to keep hand safely away from the sharp edge of the blade.
3. Loosen two blade cover bolts with extended wrench. It is not necessary to remove bolts.
4. Place blade into cutting head, sliding all the way back to the bolts. If the blade is wider than the
cutting head, center blade to head. If blade is smaller than the cutting head, first pass blade should be
mounted in center of the cutting head. After first pass is made, blade can be offset in head to allow
wheels to keep even contact with the floor and allow easy access to the wall. Blades of longer width
can be mounted in either holes or slots or put in front of blade cover bolts.
5. Securely tighten bolts.
• Blades are extremely sharp, use caution.
• A new sharp blade being used on wood or alike sub floors may work better when slightly dulled to avoid
digging or gouging.
• Use National Carpet Equipment replacement blades.
BLADE SETTING
• Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.
• Proper blade size and placement, depending on material and sub-floor type, affects performance.
• The harder a job comes up, for best results, use a smaller blade.
• Start with a narrow blade, then increase blade size to optimize cutting pass. Narrower blades work
easier than wider blades and usually clean the floor better. Wider is not always better or faster.
• Normally bevel on blade is up for concrete. Bevel down for wood or soft sub-floors.
BLADES
CAUTION:
Blades are sharp. Handle with care. Failure to do so could cause bodily injury.
