Also replace the microfilter when the

VACUUM ADAPTER DUST CANISTER
(Not included, available as accessory)
For dust extraction with a vacuum cleaner, the
(optional) vacuum adapter dust canister can be
inserted into the dust extraction system instead
of the dust canister, if required.
Press the two canister release buttons and pull
canister downward and remove from the dust
extraction system (Fig. 15).
Following a few simple tips will reduce wear on
the tool and the chance of injury to the
operator.
NOTE: The high efficiency available from the
rotary hammers can only be obtained if sharp
and undamaged accessories are used. The
"cost" to maintain sharp and undamaged
accessories is more than offset by the "time
saved" in operating the tool with sharp
accessories.
All hammers require a short period of time to
warm up. Depending on the room temperature,
this time may vary from approximately 15
seconds (90˚F) to 2 minutes (32˚F). A new
hammer requires a break-in period before full
performance is realized. This period may
require up to 5 hours of operation.

concrete, cement, brick, cinder block and other

unusually hard non-metals. The Rotary
Hammer is designed for "SDS" Carbide Tipped
Bits up to 3/4 inch diameter.
Recall these instructions for safe operation:
1. Some materials require slow drilling
speeds; whereas, others require higher speed
to produce the best results.
2. All work must be supported or secured
before drilling and steady, even pressure
applied in line with the drill bit.
3. As the drill bit cuts through the opposite
side, reduce the pressure and continue
running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics,
tiles, plastics, etc., should be drilled at low
speeds with specially designed drill bits and
lubricants.
