Precautions when working with the injection device [Toyota Carina T170]

When carrying out any repair work on the injection device, regardless of its volume, maintain cleanliness. The following points should be especially taken into account:

• All work with the injection device must be carried out in conditions of absolute cleanliness. Work outdoors should be carried out only on windless days to avoid dust ingress.
• Before unscrewing the union nuts, they should be thoroughly wiped with a cloth.
• Place all removed parts on a clean workbench and cover with paper or film. Do not cover parts with rags with lint.
• If repairs are not carried out immediately, all exposed or partially disassembled parts of the injection device must be covered accordingly or stored in closed boxes.
• Before installing the parts, check their cleanliness.
• When the device is open, do not use compressed air to blow out engine parts.
• If possible, do not move the vehicle with the injection device parts removed.
• Do not allow diesel fuel to come into contact with the hoses. If this happens, wipe the hoses immediately. Hoses damaged by diesel fuel must be replaced.
