Hi this is Carl the Landscape Guy and today
we’re going to take a look at the cockpit and steering from inside the Komatsu PC 88. This 9-ton excavator is powered by a 4 cylinder
3.3 liter diesel engine with 69 hp. Various automatic speed settings, as well
as automatic speed reduction, Eco-mode and a low noise level is supposed to make this
machine powerful and environmentally friendly. This mid-size excavator offers a spacious,
comfortable and ergonomic cab with adjustable control units. It’s equipped with a Komatsu monitor which
includes a reversing camera. Here, the cooling water temperature, the hydraulic
oil temperature and the fuel level are displayed. The time and the fuel consumption in liters
per hour are displayed. With the F4 key, I can switch between the
time and operating hours. The monitor is operated via the function keys
F1 thru F6 and the gray keys 1 to 3 down here. The symbols for this are shown in the top
right of the display. At the top left you’ll find three information
symbols: The first one is for not wearing a seatbelt, the second to show whether the
engine is on or off and the last one for whether or not the joysticks are still locked. Now I can start the excavator with the ignition
key. I unlock the joysticks by folding down the
left joystick unit. I have the option on the right here to control
the gas manually with the potentiometer. However, this only takes effect as soon as
you use the joysticks to move the excavator. After three seconds the excavator switches
the speed down again automatically. With button number 1, the automatic speed
can be switched off, then the excavator always runs in the selected speed from the potentiometer. The second symbol key controls the operating
mode and allows you to choose between several modes. The power mode is for the backhoe operation
at maximum demand. The eco mode is for lighter work such as loading
loose soil. The
fine control mode is intended for filigree load carrying work, such as fine grading or
the precise setting of lighter concrete parts, in which case the overload warning system
is also active. The next mode is be B for Breaker. But we’re going to skip over that and go
into ATT P, the attachments power mode with hydraulic operation. As a result, the automatic speed control is
now active again. Now the hydraulic attachment can be operated
by pushing the button forward on the right joystick. If an attachment needs to be changed, the
red unlocking switch must first be activated here on the left. Unlocking is indicated by a signal tone and
a symbol on the screen. In order to open it, the upper button on the
left joystick must now be pressed. Then the control pin moves out of the quick
coupler adapter plate. The plate should never be put down in the
dirt without attachments, otherwise the connections will quickly become dirty or even damaged. The hydraulic couplings are especially sensitive. The foot pedals in the middle are for driving
forwards and backwards. Two different speeds can be selected with
the number 3 key. The left pedal is here for the adjustable
boom, which can be driven up and down. The right pedal can be secured with this metal
plate. It operates the right-left adjustment of the
boom, so that working with the PC88 is also possible within the offside zone. The blue buttons are for heating and air conditioning. In addition to the blower, the temperature
and climate control can be set here. The sticker on the right side window reiterates
the most important information needed to operate the excavator. The left joystick not only opens the quick
coupler but also rotates the hook. The right joystick opens and closes the gripper. Here you can also turn on the horn or a hydraulic
breaker. I hope this video helps you in using the PC88
and was created with the kind support of Balzer Landscape Construction Company, as well as
Schlueter Construction Machinery Incorporation. Thank you for watching and make sure you check
