11-2. Precautions as to operation on a steep slope
Be sure to observe the following matters when using the machine on a steep
slope of 20 degrees and above.
Do not operate the machine when there is a risk of falling or slipping.
Before starting operation on a steep slope, check for holes, rocks, tree roots, illegal
throwaways, etc. Remove them, if any, and then carefully operate the machine.
On a steep slope, operate the machine along the contour line, and turn the machine in a
place with a small angle of inclination as much as possible.
Do not operate the machine on a slope of 35 degrees and above, because the machine is
very likely to fall down sideways.
Exercise care sufficiently also when working on a slope of less than 35 degrees, because
the machine may slip down depending on the condition of the work site.
When ropes are used on a steep slope while working together with an assistant worker,
the machine may move to a very steep slope with an angle of inclination that exceeds
the allowable angle and the risk of falling down sideways will increase, preventing safe
operation. As a maker of the machine, we will prohibit such operation.

11-1. Operation on slope
When operating the machine on a slope, move the machine upward gradually from the bottom of the
slope along the contour line.
Release the traveling lever, and the lever will be set in the neutral position, stopping the machine. For
safety, stop the machine so that it will be positioned along the contour line. When stopping the machine
vertically on a slope, the machine may not be able to stop immediately because of the inertia of the
traveling machine. The machine is provided with a hydraulic traveling system, and the step is provided
with an automatic level control sensor. When the machine is therefore turned toward the bottom of the
slope, the machine will turn smoothly because the center of gravity of the machine changes favorably,
also ensuring the operator since this way can avoid his position just below the machine during turn.
11. Operation on slope
Operation with a worn hammer knife not only prevents efficient operation but also leads
to loss of knife balance. Reverse or replace the hammer knife according to the illustration
shown below.
Replace the hammer knife immediately with a new one when it is broken or abraded
unevenly.

*1 The tightening torque of the knife mounting pin is 32-36 N.m (equivalent to M10 ordinary bolt).
Excessive tightening will damage the thread of the mounting pin.
*2 Special correction by balancing machine may be required.
