measures reduce the risk of starting the tool
accidentally.

Hammers utilize "SDS-plus" drill bits. The
"SDS-plus" system efficiently transfers drilling
torque and maximizes the energy delivered
per hammer blow.

a light oil or lubricant.

the dust shield, while twisting and pushing
inward until it locks automatically into place.

is locked into the tool holder (Fig. 5).

grasping the bit or accessory. Accessories
may be hot after prolonged use.

sleeve backwards (towards the rear of tool),
