OPERATION
1. INSERTING AND REMOVING DRILL BIT IN
SDS
Take care that the dust protection cap (1) is not
damaged when changing tools.

Clean and lightly oil the bit before inserting.
Insert the dust-free bit into the bit holder with a

— REMOVING (See Fig. B2)
Retract back the bit holder locking sleeve (2) and
pull out the bit.
WARNING:
Your new Rotary Hammer
generates powerful forces to get your job
done quickly and effectively. These forces may
cause inferior quality SDS bits to break and jam
in the chuck, We therefore recommend that only
high quality SDS bits be used with this tool.

concrete or masonry, choose the Hammer drilling
position.
For screw driving, drilling into steel, wood
and plastics choose the Rotary drilling position.

WORKING HINTS FOR
YOUR TOOL
If your power tool becomes over heated, set
the speed to maximum and run no load for 2-3
minutes to cool the motor. SDS-plus tungsten
carbide drill bits should always be used for
concrete and masonry.
When drilling in metal, only use HSS drill bits in
good condition. Where possible use a pilot hole
before drilling a large diameter hole.
