Machine Operation

CUTTING HEAD & BLADES
DIALING IN THE MACHINE
Dialing in the machine is matching the correct cutting head, blade size, blade angle and
added weight to the machine to make the material removal as easy as possible. For
every material being removed, there is an optimum blade width, thickness, sharpness,
angle and bevel (bevel up or bevel down).
SAVING TIME WITH EXTRA CUTTING HEADS
The machine is supplied with one cutting head. Having additional cutting heads will save
time on the job. Insert blades into the extra cutting heads before starting a job. When
the blade is dull, instead of taking the time to replace it or sharpen it on the job, take out
the cutting head and replace it with another. Or when a different type or size of blade is
needed, you have them ready to use.
ADJUSTING THE DUAL LIFT SLIDE PLATE AND CUTTING HEAD
• For safety prior to adjusting the dual lift hydraulic slide plate make sure the channel
guide is free of any debris and the machine is safely positioned on a
fl at surface.
• Be properly seated in the operator’s seat.
• Twist the Red Emergency Stop switch located on the right side of the operator, the
spring-loaded switch will pop up when twisted.
• Push the Green ‘ON’ button to start the machine.
• Adjacent to the left hand steering lever is a straight and narrow handle rod, this
handle rod raises and lowers the front cylinder and is referred to as the ‘cutting
head lever’. To set the height of the hydraulic slide plate start by
fi rst adjusting the
angle or pitch of the cutting head holder.
• Pull back on the cutting head lever and raise the cutting head holder to an angle
higher than the bottom of the slide plate.
• Using the lever adjacent to the right hand steering lever raises and lowers the
hydraulic slide plate and is referred to as the ‘slide plate lever’. To lower the slide
plate the operator must push forward on the slide plate lever. Reversely, to raise
the slide plate the operator must pull back on the slide plate lever.
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” off the fl oor. This setting is
most commonly used during initial scraping or removal applications; such as car-
pet, VCT, ceramic tile and wood fl ooring. (Note: The “low” setting on older model
hydraulic slide plates may stop the plate within one to two inches of the fl oors
surface.)
• High Setting: the hydraulic slide plate is positioned 6” off the fl oor or in most cases
fl ush 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.
SHEAR POINT
The shear point is the point where material to be removed will cut cleanly from the fl oor. If
the blade is too wide, too dull or too steep, the shear point is lost.
WEIGHT VS. SHARPNESS
The most common way to compensate for a dull blade is to add more weight and raise
the blade angle. Weight allows dull blades to be used to a point. Weight also causes
blades to dull and break easier. Blades of any thickness tend to catch cracks and expan-
sion joints and will bend or break the blade if set at a high angle. For best results, run a
small ditching blade at a low angle to identify as many cracks and joints as possible. If
blades are breaking, you are misunderstanding the conditions.

Low Setting: Slide plate 1/4” to 1/2” off the fl oor. The
lower the better. This is for normal removal of almost
everything.
High Setting: Slide plate is 6” off the fl oor. This is
for re-scraping glue and some thin-soft coatings.
Caution: Pinch point.
