GENERAL SAFETY RULES
Warning! Read all instructions, Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury. The term “Power Tool” in all of
the warnings listed below refers to your mains operated (corded) power tool or
battery operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) WORK AREA
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric shock if
your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) Replacement of the supply cord. If the supply cord is damaged, it must be
replaced by an electrician or a power tool repairer.
f) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
g) Have your tool repaired by a an electrician or a power tool repairer. This
power tool complies with relevant safety requirements. To avoid danger, electrical
appliances must only be repaired by qualified personnel using original spare parts;
otherwise this may result in considerable danger to the user.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries. Wear ear protectors with
impact drills. Exposure to noise can cause hearing loss.

GENERAL SAFETY RULES (cont.)
c) Avoid accidental starting. Ensure the switch is in the off position before
plugging in. Carrying power tools with your finger on the switch or plugging in
power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may result in
personal injury.
e) Do not overreach. Keep proper footing and balanceat all times. This
enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of these
devices can reduce dust related hazards.
h) Use auxiliary handles supplied with the tool. Loss of control can cause
personal injury.
4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the rate
for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any
power tool that can not be controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools, unplugged & out of the reach of children and do
not allow persons unfamiliar with the power tool or these instructions to
operate the power tool. Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with
these instructions and in the manner intended for the particular type of
power tool, taking into account the working conditions and the work to
be performed. Use of the power tool for operations different from intended
could result in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.

Before drilling into walls, ceilings etc, ensure that there are no concealed power cables
or pipes in the cavity.
Always use the side handle. This gives you greater control if the drill accessory should
become jammed.
Keep the cord clear of the drill accessory, do not wrap the cord around your arm or wrist.
Warning! Some dust created by power sanding, sawing, grinding, drilling and
other construction activities contain chemicals known to cause cancer, birth defects
or other reproductive harm.
Some examples of these chemicals are:
•Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products
• Arsenic and chromium from chemically treated timber
Your risk from exposure to these chemicals varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well ventilated
area and work with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles.
BEFORE ATTACHING OR REMOVING ANY ACCESSORIES BE SURE TO
DISCONNECT THE HAMMER DRILL FROM THE POWER SUPPLY
Attaching the Side Handle
The side handle will provide additional control, support and guidance for the drill.
The handle is adjustable to any position around the 360º handle collar mount.
Loosen the handle grip by rotating it anti clockwise to the handle collar. Slide the collar
of the handle over the chuck and onto the handle collar mount of the drill. Fasten and
secure the handle grip back to the handle collar by turning the handle grip clockwise.
Adjusting the Depth Rod
Loosen the side handle by turning it anti clockwise. Adjust the depth rod so that the
drill bit extends beyond the end of the rod to the required drilling depth. Tighten the
side handle by turning it clockwise.

OPERATION (cont.)
Chuck
Inserting Bits
Open the jaws slightly larger than the bit you are inserting. Insert the drill
bit up to the flutes making sure it is centred in the jaws. Tighten the chuck
by holding the rear of the chuck and rotating the front sleeve with your
other hand. Ensure the jaws of the chuck have clamped evenly around the
drill bit or accessory.
Periodically check that the jaws of the chuck are secure as they may
vibrate loose during operation.
On/Off Switch
To turn the tool “On” depress the On/Off switch. The tool can be locked on by first
depressing the On/Off switch and then the lock on button. Once the lock on
button has been pushed in, the switch will remain locked on.
To turn the tool “Off”, release the switch. To turn the tool “Off” when the lock on
button is engaged, simply squeeze and release the switch.
Your drill is also provided with a Speed Selection Dial, this is used to pre set any
required speed by turning the dial. Once you have set the dial you are then limited
to the speed range of 0 to the speed selected.
Forward/Reverse Lever
The direction of the chuck is controlled by the forward/reverse lever located above
the switch.
FOR FORWARD ROTATION: Move the lever to the left.
FOR REVERSE ROTATION: Move the lever to the right.
Note: Do not change the direction of rotation while the chuck is still in motion.
Carbon Brushes
The hammer drill is fitted with a brush wear indicator light. A green light shows
brushes are operating correctly. A red light shows brushes need to be checked and
possibly be replaced.
Adjusting Between Hammer and Drill Mode
The mode selector indicates the hammer and drill mode by utilising two separate
icons. The hammer icon indicates hammer mode. The drill bit icon indicates drill mode.
Note: When drilling in hammer mode, carbide tipped drill bits should be used and
the drill must be set in forward rotation.

9
Operation
Depress and release the switch to make sure the switch is not locked on before
connecting it to a power supply.
Check the rotation lever for the correct setting.
Secure the material to be drilled in a vice or with clamps to stop it from turning as the
drill rotates.
Plug the hammer drill into a power supply.
Hold the drill firmly and place the bit at the point to be drilled.
Depress the switch to start the drill.
Move the drill bit into the work piece applying only enough pressure to keep the bit cutting.
Note: Do not force the drill or apply side pressure to elongate a hole. Let the drill and
bit do the work.
Helpful Tips
When drilling hard, smooth surfaces, use a centre punch to mark the desired hole
location. This measure will prevent the drill bit from slipping off centre as you start the
hole. However, the variable speed feature allows you to start holes without centre
punching. To accomplish this, operate the drill at a low speed until you start the hole.
When drilling metals, use a light oil on the drill bit to keep it from overheating. The oil
will prolong the life of the bit and increase drilling action.
If the bit jams in the work piece or if the drill stalls, stop the tool immediately. Remove
the bit from the work piece and determine the reason for jamming.
• Keep the ventilation slots of the hammer drill clean at all times and prevent any
foreign matter from entering.
• If the housing of the hammer drill requires cleaning do not use solvents but a
moist soft cloth only. Never let any liquid get inside the tool. Never immerse any
part of the tool into a liquid.
•When brush wear indicator light shows red, have brushes checked/replaced by an
electrician or a power tool repairer.
Note: Ozito Industries will not be responsible for any damage or injuries caused by
repairing of the hammer drill by an unauthorised person or by mishandling of the tool.
