 are sensitive to jolts and

bending. For this reason a glow plug which has dropped from

a small height (approx. 2 cm) must not be used, even if there

is no obvious damage. It is absolutely necessary to follow the

installation instructions, otherwise the heater pin of the glow

plug can break and cause engine damage.
