MAINTENANCE BC 60 "Trailblazer" Brushcutter T10. Lube Drive Shafts T11. Check Engine Oil Level Check the oil level daily with the engine stopped. If necessary, add sufficient oil to raise the level to the proper mark on the dipstick. All diesel engines are designed to use some oil, so periodic addition of oil is normal.
Page 58 MAINTENANCE BC 60 "Trailblazer" Brushcutter T12. Check Hydraulic Oil Level and Quality – Sight Inspection Only Inspect the oil level on a daily basis (or every 10 hours of operation) by reading the sight gauge located on the side of the reservoir.
Page 59: Charge Pump Pressure Filter Element
MAINTENANCE BC 60 "Trailblazer" Brushcutter T14. Check Suction Strainer Element Located on the side of the reservoir, remove and inspect the filter after the first 40 hours of operation and every year thereafter. Clean as required. To access filter: 1. Turn off engine, Make certain suction valve is closed (off)(ccw).
Page 60 MAINTENANCE BC 60 "Trailblazer" Brushcutter T16. Inspect Hoses and Fittings for Leaks 1. Look for loose or disconnected hoses. An oil spot below the machine is a good indication of a loose hose or hydraulic component. 2. Make certain shut-off valve on suction strainer is OPEN.
Page 61 MAINTENANCE BC 60 "Trailblazer" Brushcutter T19. Test Hydraulic Oil Cleanliness Proper fluid condition is essential for long and productive life of hydraulic components and systems. Thorough precautions should always be observed to insure the hydraulic system is clean: 1. Filter each change of oil to prevent introduction of contaminants into the system.
Page 62 MAINTENANCE BC 60 "Trailblazer" Brushcutter T22. Check Battery Condition, Clean terminals The battery requires periodic servicing. Check the electrolyte level on a weekly (40 hour) basis. Add distilled water if necessary, but do not overfill. Overfilling can cause poor battery performance and/or early failure.
