Operation
SHUT-DOWN PROCEDURE
The machine will stop when the operator is no longer seated, or when the emergency
stop is engaged.
Remove blade or drop cutting head to the floor when machine is not in use.
SLIDE PLATE ADJUSTMENT AND SETTINGS
Manual Lift (Figure 17)
• Loosen the four bolts on the front of the slide plate with a 1-1/8’’ wrench. Slide plate
up or down to achieve the desired height of the cutting head. Firmly tighten all four
bolts when finished.
•
A low setting orients the slide plate approximately 1” (2.5 cm) off the floor. This is
for normal removal of most materials.
•
A high setting orients the slide plate approximately 6” (15 cm) off the floor. This is
for re-scraping glue and some thin-soft coatings.
Dual Lift (Figure 18)
• Prior to adjusting the dual lift hydraulic slide plate, ensure the channel guide is free
of any debris and the machine is safely positioned on a flat surface.
• To set the height of the hydraulic slide plate start, adjust the angle of the cutting
head holder with the cylinder lift lever. Pull back on the cutting head lever and raise
the cutting head holder to an angle higher than the bottom of the slide plate.
• The lever adjacent to the right hand control lever raises and lowers the hydraulic
slide plate. To lower the slide plate, push forward on this lever. To raise the slide
plate, pull back on the lever.
Settings
While the hydraulic slide plate can be adjusted to multiple positions there are two basic
slide plate settings.
• Low Setting:
The hydraulic slide plate is positioned 1” (2.5 cm) off the floor. This
setting is most commonly used during initial scraping or removal applications; such
as carpet, VCT, ceramic tile and wood flooring. (Note: The “low” setting on older
model hydraulic slide plates may stop the plate within one to two inches of the
floors surface.)
• High Setting:
The hydraulic slide plate is positioned 6” (15 cm) off the floor or in
most cases flush with the bottom of the slide plate channel guide. This setting is
most often used for re-scraping glues, mastics, thin sets and soft coating.
STEEP CUTTING HEAD ANGLE
A steep angle is only used for re-scraping. The slide plate has to be raised so the bottom
of the plate is higher or even with the bottom of the guide channels (Figure 19). Raising
the slide plate to an angle too steep when operating will cause the machine to jump and
buck. It does not give the operator a clear vision of the cutting head and it raises the
machine to operate at a unsafe height (Figure 19.1).

WARNING:
WHEN ADJUSTING THE SLIDE PLATE, KEEP FEET AND
HANDS OUT FROM UNDERNEATH THE CUTTING HEAD AND SLIDE
PLATE. FAILURE TO DO SO COULD CAUSE SEVERE BODILY INJURY.
WHEN BOLTS ARE REMOVED FROM THE SLIDE PLATE, THE CUTTING
HEAD AND SLIDE PLATE WILL DROP TO THE FLOOR.
