6 Operation

6.1 Using the support leg
On an even working surface, the support leg makes it easier to hold the fastening tool perpendicular as
attention then only has to be paid to lateral alignment. On uneven surfaces it might be necessary to retract
the support leg in order to ensure that the fastener guide is perpendicular to the working surface.
6.1.1 Retracting the support leg
CAUTION
Risk of pinching the fingers! When folding the support leg back there is a risk of trapping and
pinching the fingers between the support leg and the casing of the tool.
▶ Hold the fastening tool by the grip when extending/retracting the support leg.
1. Push against the support leg to release it from its engaged position.
