Method For Operations And Checks After Starting Engine - Komatsu HB365LC-3 Operation & Maintenance Manual

MACHINE OPERATIONS AND CONTROLS
2.
After the preheating pilot lamp goes out, turn the key of
starting switch (3) to START position (C). The engine
starts.
If the engine cannot be started with the above procedure, wait for approximately 2 minutes, then start again
from step 1.
TURBOCHARGER PROTECTION FUNCTION
The turbo protect function protects the turbocharger by keeping the engine speed at approximately 1000 rpm or
less immediately after the engine is started.
• When the turbo protect function is actuated, the engine speed is held at approximately 1000 rpm or less,
regardless of the position of the fuel control dial.
• When the turbo protect function is actuated, the engine speed is held at approximately 1000 rpm or less,
even if the fuel control dial is operated.
• When the turbo protect function is canceled, the engine speed is set to the speed for the position of the fuel
control dial.
• The actuation time of the turbo protect function is limited to 20 seconds.

METHOD FOR OPERATIONS AND CHECKS AFTER STARTING ENGINE

• If there is any trouble such as emergency stop, abnor-
mal actuation, etc., turn the starting switch key to OFF
position.
• Do not perform operations nor operate the levers or
pedals abruptly while the hydraulic oil temperature is
low. Always perform the warm-up operation for the hy-
draulic component until the hydraulic oil temperature
caution lamp displays the correct temperature.
(When the hydraulic oil temperature is low, the low
temperature display shown in the figure is given.)
• Display (A) when temperature is correct: Caution
lamp background (C) is blue.
• Display (B) when temperature is low: Caution lamp
background (C) is white.
• Perform the warm-up operation for the hydraulic com-
ponent thoroughly. If the hydraulic component is not
warm enough, the reaction of the machine to the oper-
ation of the control levers and pedals are slow, and the
machine may not move as the operator intends. Partic-
ularly in a cold weather, perform the warm-up opera-
tion for the hydraulic component thoroughly.
• Keep away from the exhaust pipe while the engine is
running and immediately after stopping the engine. Do
not bring any combustible material close to the outlet
of the exhaust pipe.
