6-2 Warm-up running
(T218081-139-0E)
(1) Engine warm-up running
When the coolant temperature is too low, the engine speed will
automatically be raised and a warm-up period set. The time
remaining in this warm-up period is displayed.
・
How to cancel engine warm-up running
1) Press the quick accelerator switch with the levers in neutral.
2) Turn the accelerator dial to medium speed or above and move
the levers.
・
Do not move any control levers including for the traveling or put any load on any system
during the engine warm-up running period.
・
If engine noise becomes a nuisance during warm-up running or in other unavoidable
situations, it is possible to cancel engine automatic warm-up running, but you should continue
the warm-up process at a lower speed which will not cause a noise nuisance.
(T218341-024-0E)
(2) Warm-up running for hydraulic oil
When the engine warm-up running period has been either
completed or canceled but the hydraulic oil was not sufficiently
heated, the message "HYD. OIL LOW TEMP." is displayed on the
monitor.
If this message is displayed on the monitor, follow the procedure
below for hydraulic oil warm-up running.
・
You must pay particular attention to warm-up running in winter and cold regions.
Excessively cold hydraulic oil can have an adverse effect on hydraulic equipment. If you start
work before the hydraulic oil is adequately warmed up, the machine's response to control lever
operations will be poor and may not match the operator's intentions, so never start work
without an adequate warm-up period. This is particularly important in cold weather.
In addition to the immediate benefits, a full warm-up every time will prolong the life of the
machine.
・
Watch the display during warm-up running to see that there is no malfunction. If any message
warning of a malfunction is displayed on the monitor during warm-up running, stop the
engine and investigate the cause before restarting the warm-up process.
・
The message is removed from the screen automatically once warm-up running is complete
and you can then begin work.
