9.3 Leak at thread end/seat
Before doing any maintenance disconnect the power and block the machine in a stable position. Because most
of the fittings in the machine are O-ring style, it is important is to know how to solve O-ring leaks. Fittings
should be tightened with the proper wrench size. Over tightening could damage the O-rings. If a leak still
persists, remove fitting and replace O-ring.
10. Cutting head & blades
Weight vs. sharpness
The most common way to compensate for a dull blade is to add more weight and raise the blade angle (see re-
scrape setting). 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 expansion 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.
Cutting head pitch
Set the cutting head angle to where the material comes up the easiest. The lowest is usually the best.
Steep cutting head pitch
The cutting head pitch can be adjusted by simply placing the cutting head axle in 1 of the 4 holes, or use the
Right-hand inner handle (for dual-lift machines from S.nr.30340 & up).
A steep angle is only used for re-scraping. The cutting head has to be raised to the highest hole.
Not raising the cutting head 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. Failure to raise the cutting head could cause machine damage and/or bodily injury.
Swiveling tool holder
The swiveling tool holder keeps the blade in contact with the floor even when the floor is uneven. When using
a flat blade, by swiveling the head over 180° allows you to use the other sharp edge on the blade without
having to replace the blade.
Saving time with extra blades, blade holders and tool holders
The machine is supplied with one tool holder. Having additional tool holders, blade holders and blades will save
time on the job. When the blade is dull, instead of taking the time to replace it or sharpen it on the job,
replace it with another prepared set. Or, when a different type or size of blade is needed, you have them ready
to use.
