TILT CYLINDER

The second handle on the control valve actuates the Tilt Cylinder. This valve has three positions and operates
in three ways.

Push the valve handle forward and you relieve pressure on the Rod End of the Tilt Cylinder, causing the Mower
Head to tilt downward.

If the handle is released, the valve will automatically return to center, and the Mower Head will be Locked in
place.

Pull the valve handle back towards you and admit hydraulic fluid to the Rod end of the cylinder causing the
Mower Head to tilt upward.

Again, if the valve handle is released, the valve will automatically return to center and the Mower Head will be
Locked in place.

10.3 Foreign Debris Hazards/Overhead Obstructions

An area to be cut must first be inspected for objects that could be thrown or that could damage the machine.
Walk through the area looking for fences, boulders, rocks, culverts, stumps or metal objects. Mark the
inspected area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect
a smaller area as well as possible, then trim away the part that has been inspected and can safely be
removed. Walk each new area again and repeat the inspection before cutting more away. Repeat as often as
necessary until the area is cleared. It can be damaging and/or dangerous to work the cutter in an area that has
not been visually inspected.

Place DANGER signs at least 300 feet beyond the perimeter of the area to be worked, not just 300 feet from
where the machine started operating! It is convenient in many cases to work in 300 foot sections. Move the
first Danger sign to the beginning of the freshly cleared area, place it, then take the first cutting area flag up to
the end of the freshly cleared area 300 feet away. Walk and inspect the next 300 feet and place the second
cutting area flag. Pick up the second DANGER sign, and take it a further 300 feet along the road or trail. Note
that in many cases the DANGER area will extend in front of and behind the machine as well as along each
side. Post signs accordingly. OPS-B- 0008

Extreme care should be taken when operating near loose objects such
as gravel, rocks, wire, and other debris. Inspect the area before
mowing. Foreign objects should be removed from the site to prevent
machine damage and/or bodily injury or even death. Any objects that
cannot be removed must be clearly marked and carefully avoided by the
operator. Stop mowing immediately if blades strike a foreign object.
Repair all damage and make certain rotor or blade carrier is balanced
before resuming mowing.

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the
operating parts of the mower head. These items could then swing outside the housing at
greater velocities than the blades. Such a situation is extremely hazardous and could result
in serious injury or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to contact such items.
