Maintenance
|
|
Service Intervals
|
|
Service Intervals:
|
The manual covers maintenance procedures like checking/renewing brushes, brake adjustments, and fluid checks. Specific timed intervals (e.g., daily, weekly, monthly) would be in a separate operator's manual or detailed within specific procedures.
|
|
Service Intervals Detail:
|
While explicit timed intervals are not listed in the product description, the manual's structure implies proactive maintenance. Sections like 'Checking and renewing the traction motor brushes' and 'Motor brush warning light' suggest regular inspection and replacement based on wear, rather than strict time-based schedules. The Linde Diagnostic Unit's 'Service interval indicator' function also points to integrated maintenance reminders, likely configurable within the system.
