4. OPERATING THE HAMMER DRILL
4. To start drilling squeeze
the On/Off switch.
5. To stop drilling release
the On/Off switch.
NOTE: PRIOR TO CHANGING MODES, THE ON/
OFF SWITCH SHOULD BE RELEASED AND THE
DRILL SHOULD HAVE COME TO A COMPLETE
STOP.
1. Choose an
operation mode:
Hammer Drill
Rotate the side mode selector to the hammer and drill icon,
and rotate the rear mode selector to the drill and hammer icon.
This setting is recommended for use when drilling holes in
concrete and other masonry products. The hammer action will
be in operation while simultaneously the drill bit rotates.
Chiselling
Rotate the side mode selector to the hammer icon, and rotate the rear
mode selector to the drill and hammer icon. This setting is recommended
for use when you desire a hammer action without the accessory rotating
which is ideal for “chiseling or chipping” away at masonry products, pick
or chisel accessory bits should be used.
Drilling
Rotate the side mode selector to the hammer and drill icon, and
rotate the rear mode selector to the drill icon. This setting is
recommended for use when you desire the accessory to rotate
without hammer action. Ideal for drilling into timber or steel when
correct accessories for such materials are used.
OPERATION
2. Ensure your workpiece is securely clamped where possible.
3. Connect the tool to the mains power supply.

• Keep the ventilation vents of the drill clean at all times.
• After each use, blow air through the drill housing to ensure it is free from all
dust particles which may build up. Build up of dust particles may cause the
drill to overheat and fail.
• If the enclosure of the drill requires cleaning, do not use solvents but a moist
soft cloth only. Never let any liquid get inside the drill; never immerse any part
of the drill into a liquid.
Gear Box Grease Replenishment
The grease in the gearbox will require replenishment after approximately 50
hours accumulative use. After this time, add approximately 50 grams (approx
2 – 3 teaspoons) of the grease (supplied), into the gearbox. First remove
the grease cap from the drill by using the pin spanner. Once removed, add
the grease through this hole. Ensure the grease cap is secured back into
position prior to operation. Further grease (normal ball bearing grease) can be
purchased through your local Bunnings Warehouse.
Carbon Brushes
When the carbon brushes wear out, the drill will spark and/or stop. Discontinue
use as soon as this happens. They should be replaced prior to recommencing
use of the drill. Carbon brushes are a wearing
component of the drill therefore not covered under
warranty. Continuing to use the drill when carbon
brushes need to be replaced may cause permanent
damage to the drill. Carbon brushes will wear out
after many uses but when the carbon brushes
need to be replaced, take the drill to an electrician
or a power tool repairer for a quick and low cost
replacement. Always replace both carbon brushes at the same time.
Note: Ozito Industries will not be responsible for any damage or injuries caused
by the repair of the drill by an unauthorised person or by mishandling of the
drill.
