ELECTRICAL SAFETY
WARNING! When using mains-powered equipment, basic safety
precautions, including the following, should always be followed to reduce
the risk of fire, electric shock, personal injury and material damage.
Please read and understand the manual prior to operating this tool.
Save these instructions and other documents supplied with this tool for future reference.
The electric motor has been designed for 230V and 240V only. Always check that
the power supply corresponds to the voltage on the rating plate.
Note: The supply of 230V and 240V on Ozito tools are interchangeable for
Australia and New Zealand.
If the supply cord is damaged, it must be replaced by a qualified electrician or a
power tool repairer in order to avoid a hazard.
Note: Double insulation does not take the place of normal safety precautions when
operating this tool. The insulation system is for added protection against injury
resulting from a possible electrical insulation failure within the tool.
Using an Extension Lead
Always use an approved extension lead suitable for the power input of this
electrical equipment. Before use, inspect the extension lead for signs of damage,
wear and ageing. Replace the extension lead if damaged or defective. When using
an extension lead on a reel, always unwind the lead completely. Use of an
extension lead not suitable for the power input of the equipment or which is
damaged or defective may result in a risk of fire and electric shock.
It is recommended that the extension lead is a maximum of 25m in length. Do Not
use multiple extension leads.

GENERAL POWER TOOL SAFETY WARNINGS
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 mainsoperated (corded) power tool or battery-operated (cordless) power tool.
Save these instructions
1. Keep work areas clean.
Cluttered work areas and benches can cause accidents.
2. Consider work area environment. Do not expose your equipment to high
humidity or rain. Do not use your equipment in damp or wet conditions. Keep
the work area well lit. Do not use your tool where there is a risk of causing fire
or explosion, e.g. in the presence of flammable liquids and gases.
3. Keep children away. Do not allow children, visitors or animals to come near
the work area or to touch the equipment or accessories.
4. Dress appropriately. Wear the appropriate protective clothing. Wear a protective
hair covering to keep long hair out of the way.
5. Guard against electric shock. Prevent body contact with earthed or grounded
surfaces. Electrical safety can be further improved by using a high sensitivity (30
mA / 30 mS) residual current device (RCD).
6. Do not overreach. Keep proper footing and balance at all times.
7. Stay alert. Watch what you are doing. Use common sense. Do not operate the
equipment when tired.
8. Secure work piece. If required, use clamps or a vice to hold the work piece.
9. Extension leads. Before use inspect the extension leads and replace if
damaged. When using the equipment outdoors, only use extension leads
intended for outdoor use and marked accordingly.
10. Use appropriate equipment. Only use the equipment as outlined within this
instruction manual. Do not force the equipment to the job of heavier duty
equipment. The equipment will do the job better and safer at the rate for
which it was intended. Do not force the equipment.
WARNING!The use of any accessory or attachment, or performance of
any operation with this equipment other than those recommended in this
instruction manual may present a risk of personal injury.
11. Check for damaged parts. Before use carefully check the equipment and
power lead for damage. Check for misalignment and seizure of moving parts,
breakage of parts, damage to guards and switches and any other conditions
that may affect its operation. Ensure the equipment will operate properly and
perform its intended function. Do not use the equipment if any parts are
damaged or defective. Do not use the equipment if the switch does not turn it
on and off. Have any damaged or defective parts repaired or replaced by an
electrician or a power tool repairer. Never attempt any repairs yourself.
12. Unplug the equipment. Unplug the equipment when it is not in use, before
changing any parts, accessories or attachments and before servicing.
