If the body shell of your Ofna DM-1 is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. If they are scratched, change them as soon as possible. At the same time, change the O-Ring seals to prevent more leakage. If you feel a jolt as you change direction, this means the oil has leaked out and must be topped up. The damper shafts should push in and pull out with a smooth action. Next, for those Ofna models with oil filled shock absorbers, remove them from the chassis and dismantle the coil springs. Then, take a screwdriver and box spanner and check each self tapping screw and nut for security, taking care not to over tighten. When you receive your used Ofna Touring Car, make a general visual inspection of the chassis, front and rear wishbones, suspension shock towers etc, for any broken parts that may need to be replaced.
