controlled by the pressure applied to the
trigger switch (8). The further the trigger is
depressed the higher the speed.
Gear Selection
• Select gear 1 on the gear switch (3) for the
low speed, high torque gear. Suitable for
low speed drilling and driving screws and
fasteners.
• Select gear 2 on the gear switch for the
high speed, low torque gear. Suitable only
for high speed drilling.
Note: Always read the documentation
provided with drill bits and accessories for the
recommended or maximum speed setting and
use the most appropriate gear. See 'Technical
Data' for the maximum no load speed of each
gear.

Drilling Concrete

• Using hammer drill mode, apply pressure
to the rear of the rotary hammer, in line
with the drill bit.
• For efficient drilling, it is advisable to use
TCT (tungsten carbide tipped) drill bits.
Ensure that drill bit size is within the
maximum capacity of the rotary hammer
(see 'Technical Data').
• Do not apply too much pressure if debris
blocks the drill hole. Run the rotary
hammer slowly, and remove the bit from
the hole. Repeat until hole is cleared.

ACCESSORIES

Use only accessories with an allowable speed
matching at least the highest no-load speed of
the tool.
