HK4400
Operating Machine
Adjusting Engine Speed
•
The engine rpm is controlled by the
throttle control lever. Start at low throt-
tle, allow engine to warm up, then
operate at full throttle. When sweeping
and transporting the machine, operate
at full throttle. When raising and
dumping the hopper, operate at low to
mid throttle.
Turning the Deck Rotor/Paddle ON/OFF.
•
Using the paddle switch on the
console, place the switch in the ON
position. When switching ON, make
sure the engine rpm is at low throttle.
Once ON, speed the engine up to full
throttle.
•
To turn the deck ON, the operator
must be in the seat, the hydraulic oil
temperature must be less than
190° F, and hydraulic oil must be
present in the tank.
Raising and Lowering the Deck.
•
Use the LH lever to operate the lift
cylinder located on the rear side of the
deck.
•
The deck lift cylinder is attached to
a pivot link that allows the deck to float
with the contour of the ground. When
the deck is lowered, hold the lever a
few more seconds to ensure that the
deck is in the float position.
•
A deck height indicator is located on
the front RH side of the deck so that
the operator can easily view the deck
height.
Filling the Hopper
•
The hopper debris level can be de-
termined by looking through the sight
glass windows located on each side of
the hopper.
•
The large debris door can also be
opened to get a better view of the
debris level inside the hopper. It can
be used to place large debris, that
cannot be picked up by the
machine, inside the hopper.
•
If the hopper is overfilled, it can cause
the paddle rotor to plug.
