BASIC CORDLESS HAMMER DRILL OPERATIONS

8.7 TORQUE SELECTION CONTROL - FIG. 6

By turning the collar

amount of torque.

Settings 1-21 provide a facility for setting the torque to

the required level. For example, this means that repetitive

driving of screws of the same size will be driven into the

material to the same torque, thus giving the same fixing

strength, or in the case of countersunk screws, these will

all be driven to the same depth in the material.

The torque control prevents the heads of small diameter

screws being twisted off when correctly set.

By turning the collar

and screwdriving functions. Set the "twist drill" setting

in the "hammer drill" setting

intended for drilling into masonry, etc. Turn the collar to the

screwdriving.

8.8 HOLDING THE DRILL - FIGS. 7 - 8

The drill casing is designed to be held comfortably in two

ways,

1. By the handle.

2. Or by the in-line support grip.

8.9 DRILLING WOOD AND PLASTIC

To prevent splitting around the drill holes on the reverse

side, place a piece of scrap timber under the material to

be drilled.

8.10 DRILLING METAL

Metals such as sheet steel, aluminium and brass may be

drilled. Mark the point to be drilled with a centre punch

to help the drill bit tip to locate. A drop of oil on the area

will aid cutting and help prolong the life of the bit.

8.11 DRILLING MASONRY

Start drilling at a low speed to prevent the drill bit from

wandering. Once penetration is achieved, fully depress the

trigger to achieve maximum speed and hammer power.

8.12 SCREWDRIVING

To prevent slip or damage to the screw head, match the screwdriver bit to the screw head

size. To remove screws, move the direction switch to the reversing position and apply

pressure to the screw head and depress the trigger slowly).

Screwdriver bits are a consumable items.

Before drilling check that there are no hidden hazards such as electrical cables, water or gas

pipes running below the surface use a metal/voltage detector.

Do not expose either the drill or charger to rain or water.

Do not overcharge the battery (more than six hours) as this could damage the battery cells.
