. OPERATION DETAILED CONTROLS AND GAUGES and add fuel. REMARK If the indicator enters red range (B), there is less than 41 liters 3 - 17 Fuel Gauge This meter (9) displays the lev el of the fuel in the fuel tank. During operations, the indicator shoul If the indicator enters red rang d be in the black range. e (A) during operations, there is less than 60 liters (15.85 US gal) of fuel remaining in the tank, so check (10.83 US gal) of fuel remainin When the indicator is in the re g. d range (A) to (B), fuel level monitor (1) lights up red. The correct fuel level may not be displayed for a short time when the starting switch is turned O N, but this is not an abnormality.

Hydraulic Oil Temperature Gau ge lic oil temperature. r should be in the black range. Meter (10) displays the hydrau During operations, the indicato If the indicator enters red range (A) during operations, the hydraulic oil temperature has gone abov e 102°C (215.6°F). w idle and wait for the hydraulic oil Stop the engine or run it at lo temperature to go down. REMARK When the indicator is in the temperature is as follows. red range (A), the hydraulic oil than 102°C (215.6°F) than 105°C (221°F) red range (A) to (B), hydraulic oil up red. C) when the engine is started, the Red range position (A) : More Red range position (B) :

More When the indicator is in the temperature monitor (1) lights If the indicator is at position ( hydraulic oil temperature is mo re than 25°C (77°F), and hydraulic oil temperature monitor (1) ligh ts up white. In this case, carry out the warming-up operation. For details, see "Warming-up Operation (PAGE 3-83)". Service Meter This monitor (11) displays the t otal time that the machine has been operated. Use the time display to set th e maintenance interval. When the rvice meter advances even if the by 1 for every hour of operation, d. starting switch is ON, the se machine is not moving.
