Hydraulic System Warm-up Switch
Some engines may have a hydraulic fluid warm-up sys-
tem. This system may be used to warm the hydraulic
fluid when the ambient temperature is below 0°C (32°F)
and boom movement is sluggish because of cold fluid.
There is a toggle switch for the warm-up system on the
lower control panel and one on the left side of the upper
control panel.
The engine must be running and the switch used to turn
the system on, must be at the same location that the
engine was started. For example, if the engine was started
from the lower controls, the warm-up switch at the lower
controls must be used for the system to operate.
Machine functions are not operational while using the
hydraulic warm-up system.
Circuit Breaker Reset Buttons
The lower control panel electrical system has a circuit
breaker for the lift/swing circuit (refer to Figure 6.2). There
is a reset button for the circuit breaker on the bottom of
the lower control panel
The wiring box (refer to Figure 6.3) electrical system has
a circuit breaker for the main, run, and throttle circuits.
There is a reset button for each circuit breaker on the
front of the wiring box.
Figure 6.3 – Wiring Box
The upper control panel (refer to Figure 6.4) has a circuit
breaker for the main and drive circuits. The circuit breaker
reset buttons are on the front of the upper control panel.
Figure 6.4 – Upper Control Panel Front
The circuit breakers protect the electrical wiring and com-
ponents from electrical overload in case of a short circuit
or other fault.
