AUTO-GREASING SWITCH

This switch (1) is inside the base under the cab and is used to switch between automatic and manual greasing. Normally, keep this switch at the AUTO position. When using a grease gun, set the switch to MANUAL.

AUTO GREASE/GREASE GUN SELECTOR LEVER

This lever (2) is used to select automatic or manual greasing in the same way as the auto-greasing switch. Normally, keep this lever at the AUTO GREASE position. When using a grease gun, check first that the grease pump is not carrying out auto-greasing [if it is carrying out auto-greasing, wait until the grease pump stops (within approx. 1 minute)], then set the lever to the GREASE GUN position.

Auto Greasing Selector Lamp

This lamp (3) informs the operator if the auto-greasing system is in auto-greasing status or in manual greasing status. When it is in auto-greasing status, the green AUTO lamp lights up.

When it is in manual greasing status, the green MANU lamp lights up.

AUTO-GREASING CAUTION LAMP

This lamp (4) lights up if an abnormality occurs in the autogreasing system. Check the engine from the content of the display on the auto-greasing controller inside the cab base, then carry out repair work.

Set the auto-greasing controller to the OFF position when carrying out repair work. If the starting switch is turned OFF, the controller is also turned OFF.

Remark

● To turn the auto-greasing controller OFF/ON, press power switch (1). Each time the power switch is pressed, it switches OFF → ON → OFF.

● If the engine has not been studied, and the standing switches left at the ON position, CONTROLLER REST FAILURE is displayed on the auto-greasing controller display and the auto-greasing caution lamp lights up, but this does not indicate any abnormality. When the starting switch is turned OFF, the condition returns to normal.
