GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
The term “power tool" in all of the warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or 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) 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.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply. Use of an RCD reduces the risk of
electric shock.
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 personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your finger on the switch or energising power tools
that have the switch on invites accidents.

GENERAL POWER TOOL SAFETY WARNINGS
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 balance at 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 dust
collection can reduce dust-related hazards.
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 cannot be controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source and/or the battery pack from
the power tool 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 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
tool's 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, taking into account the working conditions and the work to
be performed. Use of the power tool for operations different from those
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.
b) If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.

7. Ensure that the replacement wet sharpening wheel conforms to the manufacturer's
specification.
8. Fit the replacement wet sharpening wheel to the tool.
9. Secure the wet sharpening wheel by tightening the nut clockwise with an 18mm
spanner.
10. Replace the water trough (14) and ensure the water trough plug (13) is in position.
Abrasive wheels should be discarded when:
1. The diameter approaches that of the driving flanges.
2. The tool rest can no longer be correctly adjusted to the wheel diameter.
3. The wheel no longer grinds efficiently because of reduced peripheral speed.

bench grinder reaches maximum speed.
WARNING! Do not grind with the eye shield raised: always wear safety
glasses when operating the wet & dry bench grinder.
Guide the work against the tool rest and into the grinding wheel slowly and smoothly
without bumping.
Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure
required to complete the job.
By moving the work back and forth across the wheel you will prevent grooves.
OPERATION (cont.)
!
!

10
Wet Grinder Operation
Ensure the wet & dry bench grinder is switch off.
Fill the water trough (14) with clean water to a level just below the top edge of the
water trough (14).
Switch the tool on.
The wet sharpening wheel (15) turns slower than the dry grinder wheel. Because
the the wet sharpening wheel (15) is water cooled and runs slower, it will produce
a fine edge on the implement being sharpened without the risk of burning the
material.
Tools to be sharpened can either be sharpened free-hand or by using the notches
on the edges of the water trough (14) as a guide.
Wheel Dressing
Dressing a wheel is done to renew sharpness or to true up the face of a wheel.
A build up of metals and dirt will become embedded in a wheel as it is used. Use
a wheel dressing tool (not supplied) to clean wheels. In so doing, it will also
improve the wet & dry bench grinder’s performance.
Note: New wheels sometimes require dressing to true up their face.
Cleaning and Lubrication
Use only mild soap and a damp cloth to clean the tool. Never let any liquid get
inside the tool; never immerse any part of the tool into a liquid. Self lubricating
bearings are used in the tool and periodic lubrication is not required.
Note: Ozito Industries will not be responsible for any damage or injuries caused
by repairing of the bench grinder by an unauthorised person or by mishandling of
the tool.
