Selecting Mode And "Torque; Guidelines For Use - Baumr-AG HD2 User Manual

20V Cordless Hammer Drill / Driver HD2

Selecting Mode and "Torque"

For drill mode operation, "full torque" should be used – this is the " " setting (circled in the image).
• For impact drill mode, a suitable carbide-tipped masonry bit and "hammer action" must be used – this is the
" " setting (circled in the image). • For screwdriver mode operation, apply a torque setting that is suitable to
the fastener type and material. For example, smaller diameter screws or softer materials may require lower
torque than larger screws or harder materials. • Do NOT change the torque while the tool is running.
The drill has a range of "torque" settings that control how much
rotational force to apply before the internal clutch disengages the
chuck. This is used for screwing in fasteners, so you can adjust how
"tight" the fastener is set.
•
To set torque, rotate the torque control ring (D) so the required
setting is next to the reference arrow (E). "1" is the lowest setting.

Guidelines for Use

Fully understand all operational
Drilling
•
Use the "full torque" setting (
•
Where possible, and especially on metals and smooth materials, "centre-punch" the hole location.
•
Always hold the tool "square" to the face of the work surface. That is, drill straight. Do not apply
sideways pressure to elongate holes etc.
•
Apply sufficient pressure to cause the drill to cut into the material. Do not use excessive force.
•
Adjust speed as required – generally, start the hole at a slower speed until the drill is cutting, then
increase speed. Do not use excessive speed or you may over-heat and blunt the bit or cause excessive
wear in the tool. Use a speed that is suitable for the drill bit type and material being drilled – harder
materials and larger diameter bits require slower cutting speeds.
•
When drilling through holes, place a piece of wood under the work-piece to reduce burring / tearing.
Impact (Hammer) Drilling
•
Use the "hammer" setting ( ).
•
Use carbide-tipped masonry bits only and run at high speed.
Screwing
•
Use the correct screwdriver bit for the fastener head.
•
Use a suitable torque setting for the fastener size and material being screwed into. Generally, smaller
diameter screws or softer materials may require lower torque than larger screws or harder materials.
•
Apply sufficient pressure to prevent the screwdriver bit slipping from the screw head, especially when
using high torque.
