OPERATING INSTRUCTIONS RH 30 F Inspection and servicing Idlers The idlers have a permanent oil resp. grease filling. Inspect the idlers visually for leaks after each working shift. If leaks are detected, check oil level.
Checking the oil level The checking plug (arrow, Fig. 3-81:) is located on the inside of the idler.
To check the oil level, the checking plug must be ca. 30° above the horizontal axis (2 o'clock position) (Fig. 3-81:). Unscrew the checking plug. The oil level must reach the lower edge of the opening. If the oil level is below the opening, move the excavator until the plug opening is in the horizontal plane (3 o'clock position). If no oil emerges from the opening in this position, it is essential to check the idler seals. Work can be continued temporarily with the excavator if the oil level is topped up and checked at short intervals.
Filling in oil The checking-plug opening must be in the same position as for oil-level checking (2 o'clock position). Fill in oil up to the lower edge of the opening.
