Risk of being crushed. Press lightly The steering can quickly drift off in either direction.

•Now adjust the servo laterally until the steering stands still. The servo is pressed lightly against the steering column when adjusting.

•When the steering stands still the screws (A) are tightened again.

•Now test the servo setting by steering to the left and right, then release the steering and make sure the steering stands still, it should not drift in any direction. If the steering drifts the adjustment must be restarted from the point "Switch on the voltage" above.

•Lower the truck to the floor and test drive.

The distance between the servo unit and the steering column directly affects the gain on the servo. With 4.5° turning of the tiller arm relative to the drive wheel, you can measure 95% of the battery voltage across the steering motor.

12.3.2 Adjusting the steering chain

•Check the measurement between the sleeve (21) and the fixed bracket on the drive unit.
