2 Maintenance

(1) Water discharge from sedimenter

When sedimentor indicator lights up …

Press the priming pump until fuel coming through the bleed plug contains no bubble.

    b)Fasten the bleed plug to confirm that there is no fuel leakage from the plug screw.

(3)Replacing the fuse

The fuse protects the electric system against overcurrent. Use the specific ampere rating of the fuse. Check to see that the components in each circuit are operating properly. If every component in a circuit is not functioning, it is an indication that the corresponding fuse is blown out. Replace the blown fuse with a spare fuse of the same capacity. If a part of the components in the circuit does not function properly, it is suspected that a bulb has burnt out. The burnt bulb should be replaced with a new one of the same capacity.

(4)Replacing or repairing the tire

Prepare tools and jack necessary for replacing or repairing tires.

  1. a) Front wheel

  • Again jack up the truck until the tire leaves off the ground. Remove the hub nuts, and detach the wheel.
  • The wheel should be reinstalled in the reverse order: The hub nuts should be tightened in the diagonal order evenly.

After reinstallation, check the tire for proper inflation pressure.
