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
Manual Lift (Figure 16)
Note:
When adjusting 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 the slide plate will drop down to the
floor. Having a second person to hold the slide plate in position will greatly reduce this
risk.
•
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.
Slide Plate Settings
While the hydraulic slide plate can be adjusted to multiple positions, there are two basic
slide plate settings:
• Low Setting (Figure 17):
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 17.1):
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).
