Warming Up Operation - Hitachi ZW 310-6 Operator's Manual

Warming Up Operation

IMPORTANT: Right after the engine starts, the engine
speed will be kept to slow idle speed for maximum
35 seconds when the coolant, hydraulic oil or
transmission oil temperature is low, or for 3 seconds
at normal temperature even if accelerator pedal (3) is
operated.

WARNING: After starting the engine, start the
machine operation only after confirming that the
engine speed changes by operating accelerator pedal
(3).
Otherwise, the machine or the front attachment may
unexpectedly start moving, possibly causing accidents
such as crash.
d
CAUTION: Operating the machine without warming
up operation causes damage to the engine and
hydraulic components. Be sure to perform warm
up operation not only to protect the hydraulic
components from being damaged but also to ensure
safe operation.
If the machine is operated excessively with the hydraulic
oil temperature below 20 °C, damage to the hydraulic
components may result. After starting the engine, sufficiently
perform warm up operation as described below before
operating the machine until the hydraulic temperature
increases to higher than 20 °C.
1. Run the engine at slow idle speed without operating the
accelerator pedal (3) for about 3 to 5 minutes without
load.
2. Increase the engine at medium speed. Raise the bucket
above the ground and hold bucket control lever (1) in
the tilt position for 10 seconds. (Do not operate control
levers other than the bucket control lever at this time.)
