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 ADJUSTMENTS AND SETTINGS
Dual Lift (Figure 17)
• 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 (Figure 18) 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.
Slide Plate Settings
While the hydraulic slide plate can be adjusted to multiple positions, there are two basic
slide plate settings:
• Low Setting (Figure 19):
the hydraulic slide plate is positioned 1” 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 (Figure 19.1):
the hydraulic slide plate is positioned 6” 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).
