- Lubrication: Apply appropriate lubricant to moving parts, joints, and gears as per manufacturer recommendations.
- Track Inspection: Check the tracks for wear, damage, or trapped debris. Ensure proper tension.
- Battery Care: Store batteries in a cool, dry place. Follow charging guidelines to prevent overcharging or deep discharge.
7. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Model does not respond | Low battery (model/remote), power switch off, binding issue | Charge batteries, ensure power is ON, re-bind remote controller |
| Weak hydraulic movement | Low hydraulic fluid, air in system, pump issue | Check/refill hydraulic oil, bleed air from system, inspect pump |
| Tracks not moving smoothly | Debris in tracks, track tension incorrect, motor issue | Clean tracks, adjust tension, check motor connections |
For persistent issues, contact LESU customer support or a qualified RC model technician.
