4-2. TROUBLESHOOTING OF CHASSIS

STEERING/ SUSPENSION/ FRONT WHEELS/ FRONT BRAKES
Operation Cautions:
1. Leg shield lower must be dismounted before the front wheel is dismounted. Use a
jack to raise the wheel above ground and support the car body firmly.
2. The brake inner cylinder and lining shall be kept free form grease during operation to
avoid driving danger caused by braking effort reduced by grease.
Troubleshooting
Steering too tight (heavy)
1.The bolt of ball bearing fastening at the top of the steering column too tight.
2. Balls of the steering system broken.
3. The conical base for steering ball bearings damaged.
4. Bad curvature of the front fork comp.
5. Bad curvature of the front wheel shaft or deviation of the tire.
6. Insufficient tire pressure.
Straight driving impossible due to deviation of the steering wheel:
1. Deviation of the front fork comp.
2. Unequal working of the left and right shock absorber beside the front fork comp.
3. Running deviation due to the deviation of the front axle.
4. Deformation of the front tires.
5. Deformation of wheel rim.
Front shock absorber too flexible:
1.Shock absorber spring constant too low.
2. Shock absorber spring fatigue.
3. Lack of oil in the shock absorber resulting from leakage.
4. Loose front fork comp axle bolts.
