ADJUSTING THE DUAL LIFT HYDRAULIC SLIDE PLATE (CONT.)
A “high” setting has the hydraulic slide plate positioned six inches 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 coatings.
The operator may now install the cutting head attachment based on the type of scraping
application required.
Make sure to wear proper work gloves when installing or removing any cutting head
attachments.
With the machine off, slide the shaft off the cutting head attachment into the cutting head
holder and secure it to the holder with a cutting head clip.
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 slide plate is higher or even with the bottom of the guide channels (See Figure X).
Not raising the slide plate when operating the machine at a steep angle 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 operating height (See Figure Y). Failure
to raise the slide plate could cause machine damage and/or bodily injury.
SWIVEL HEAD
The swivel head keeps the blade in contact with the
fl
oor even when the
fl
oor is uneven.
When using a
fl
at blade, by swiveling the head over 180° allows another sharp edge on
the blade without having to replace the blade.
CUTTING HEAD INSERTION
With machine off, insert desired cutting head into cutting head holder. Secure with cutting
head clip.
SHANK BLADE INSERTION
Shank blades do not require a cutting head. Insert desired shank blade into cutting head
holder. Secure with cutting head clip.
BLADE SETTING
•
Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.
•
Proper blade size and placement, depending on material and sub-
fl
oor type, af-
fects performance.
•
The harder a job comes up, for best results, use a smaller blade.
•
Start with a narrow blade, then increase blade size to optimize cutting pass. Nar-
rower blades work easier than wider blades and usually clean the
fl
oor better.
Wider is not always better or faster.
•
Normally bevel on blade is up for concrete. Bevel down for wood and shoe blades
for soft sub-
fl
oors.
•
KEEP BLADES SHARP.

CAUTION:
WATCH OUT FOR OBSTRUCTIONS IN THE FLOOR (IE: EXPAN-
SION JOINTS, NAILS, BOLTS, RECEPTACLES). THEY WILL BREAK BLADES.
