Maintenance Essentials & Common Parts
Pro Tip:
To avoid hydraulic overheating, regularly clean the radiator and oil cooler screens—especially during summer use or dusty jobsites.
Common Issues & Quick Fixes
Hydraulic Performance Lag
Often due to dirty auxiliary filters or worn O-rings. Use control valve rebuild kits to restore function.
Blade Won’t Angle
A faulty solenoid or bent cylinder can disable blade tilting. Inspect and replace using blade cylinder seal kits.
Track Tension Loss
Track slack typically results from leaking grease adjusters. Restore tension and replace with track adjuster components.
Serial Number Location
The serial number is stamped on a plate located on the front-right frame of the undercarriage near the boom arm. Always refer to this number when sourcing exact parts.
