PREPARING MACHINE FOR JOB
Blade Setting
Note:
This machine is designed to remove soft good materials.
•
Depending on material and sub-floor type, proper blade size and placement affect
performance.
•
For harder jobs, use a smaller blade.
•
Start with a narrow blade, then increase blade size to optimize cutting pass. Nar-
rower blades work easier than wider blades and usually clean the floor better.
Wider is not always better or faster.
•
Normally, bevel on the blade is up for concrete (Figure 4); bevel down for wood
(Figure 5).
•
Dull blades greatly affect the performance of the machine and reduce cutting ability.
Re-sharpen or replace blades as needed.
•
Remove any nails or metal obstructions on wood/wood-like flooring prior to use to
avoid blade damage.
•
Blades can be offset in cutting head for easier access to toe kicks or removal along
the wall (Figure 6).
•
Sheet vinyl, solid vinyl, rubber tile, urethane, or PVC sheet roofing will need to be
scored for best removal results. It recommend to use a self-scoring blade.
•
Self-scoring blades eliminate the need for pre-scoring material. Depending upon
the type of material being removed and the sharpness of the blade and scoring
wings, the self-scoring blades may make it harder to control the machine. Keep
scoring wings sharp at all times.
Blade Changing
1.
Place a flat piece of wood under the front of the machine.
2.
Use the supplied extended 7/32 “T” wrench (Domestic) or a 6 mm Hex wrench
(International) with at least a 3” (76 mm) extension to keep hand safely away from
the sharp edge of the blade. Loosen the two Allen head bolts.
3.
Place blade into the cutting head and slide back until fully seated against the ma-
chined edge. If the blade is wider than the cutting head, center the blade to the
head. If the blade is smaller than the cutting head, the blade should be mounted in
the center of the cutting head during the first pass. After the first pass is made, the
blade can be offset in the head to allow the wheels to keep even contact with the
floor and provide easy access to the wall.
4.
Tighten the bolts.
