Common Issues & Troubleshooting

Problems operators frequently encounter with Multi-Terrain Loader machines.

Medium Track Slippage

Symptoms

  • • Reduced traction
  • • Difficulty climbing slopes
  • • Uneven ground engagement

Cause

Worn tracks, improper track tension, or mud/debris buildup in the undercarriage.

Fix

Adjust track tension, clean the undercarriage, or replace worn tracks.

💡 Prevention Tip

Regularly inspect and adjust track tension. Clean the undercarriage frequently, especially after working in muddy conditions.

High Hydraulic Leaks

Symptoms

  • • Loss of hydraulic power

Pro Tips from the Field

Wisdom from experienced Multi-Terrain Loader operators.

1

Always grease the undercarriage after washing the machine to prevent rust and corrosion.

2

When operating in dusty conditions, clean the air filter more frequently to prevent engine damage.

3

Use a high-quality fuel additive to help keep the fuel system clean and prevent fuel gelling in cold weather.

4

Inspect the tracks for embedded rocks or debris regularly to prevent damage.

5

Allow the engine to warm up properly before operating under heavy loads to prevent premature wear.

6

Park the machine on a level surface and lower the bucket to the ground when not in use to relieve pressure on the hydraulic system.
