Ozito RHR-850, Operation Manual

Fitting and Using the Dust Cover

The dust cover (17) catches dust and debris generated while
using the drill over head. It’s advised to use the dust cover (17)
when drilling over head to minimize dust and debris entering
the drill’s air vents and extending the drill’s life.  

To fit the dust cover (17), remove the accessory, place the closed
side of the dust cover (17) over the accessory and then back into
the SDS+ accessory holder (1) as previously described (Fig.4).

Chuck and SDS+ Adaptor 

The chuck adaptor is a SDS+ shank combined with a 13mm keyed chuck (15) for
use with normal drill bits. To use the chuck adaptor, first remove a SDS+ accessory
from the SDS+ accessory holder if previously assembled, then insert the SDS+
shank of the adaptor in the same way as previously described in SDS+ Accessories.

DO NOT USE THE CHUCK AND SDS+ ADAPTOR IN HAMMER DRILL
MODE. DOING SO COULD DAMAGE THE CHUCK. DAMAGE TO THE
CHUCK IS NOT COVERED UNDER WARRANTY. 

Inserting Bits into the Chuck Adaptor

Open the jaws slightly larger than the drill bit
you are inserting (Fig.5). Insert the drill bit up
to the flutes making sure it is centered in the
jaws by holding the rear of the chuck and
SDS+ adaptor (15) and rotating the front with
your other hand. Once the chuck jaws have
been clamped evenly around the drill bit, use
the chuck key (16) to tighten all three chuck
positions fully (Fig.6).

On/off Switch

To turn on the drill, squeeze the On/Off switch (6) on the rear operating handle. 

To turn off the drill, release the On/Off switch (6). 

Note: 

Always wait until the accessory has stopped moving before putting down

the drill.

Changing Drilling Modes

Prior to changing modes, the On/Off switch (6) should be released and the drill
should have come to a complete stop.
