ASSEMBLY
THE 550 COMES DISASSEMBLED.
1. Loosen both handle T-bolts on the handle frame.
2. Insert handle into handle frame (See Figure A) and adjust the handle to the desired
height.
3. Retighten T-bolts on the handle frame (See Figure A).
WHEEL ADJUSTMENT
Adjusting the wheel angle will change the blade angle to the fl oor. A steep wheel angle is
recommended on hard tear-outs such as tile over concrete. A low wheel angle is recom-
mended for vinyl removal over plywood fl oors. These are estimations. Experiment with
the angle to see what works the best for the jobs application.
Rotate handle clockwise to raise wheels, counterclockwise to lower wheels to the desired
blade angle (See Figure B).
Note: Adjustment by trial at the beginning of a job will allow optimum performance.
HANDLE ADJUSTMENT
AFTER THE PROPER WHEEL ADJUSTMENT IS ACHIEVED, ADJUST THE HANDLE
No matter what the wheel angle is set at, the handle should be adjusted to the “belt-line”
of the operator or to what the operator is comfortable with. (See Figure C)
• Low setting works best on soft sub fl oors, plywood, luan, particleboard and wafer
board.
• In some cases, a higher setting works best on direct glued down carpet, vinyl or tile
on concrete in some cases.
Make certain handle and bolts are secured tightly.
NOTE: Adjustment by trial at the beginning of the job will allow optimum performance.
