ELECTRICAL SAFETY
!
!

5
GENERAL
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) 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.
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.
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 balance at all times. This enables
better control of the power tool in unexpected situations.

GENERAL
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.
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.
h) This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
i) Children should be supervised to ensure that they do not play with
the appliance.
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.

This appliance is not intended for use by young or infirm persons unless supervised
by a responsible person to ensure that they can use the appliance safely.
Young children should be supervised to ensure that they do not play with
the appliance.
• Never operate the wet & dry bench grinder with cracked or damaged wheels.
Always replace cracked or damaged sharpening and grinding wheels immediately.
• Always disconnect the wet & dry bench grinder from the power supply prior to
making any adjustments.
•Always use safety equipment including, earmuff, goggles, gloves, hat and clothing
when operating the wet & dry bench grinder.
• The adjustment of the spark arrestor should be made frequently, so as to
compensate the wear of the wheel, keeping the distance between the guard and
the wheel as small as possible, but in any case not greater than 2mm.
• The adjustment of the work rest should be done gradually so as to compensate
the wear of the wheel, keeping the distance between the work rest and the wheel
as small as possible, but in any case not greater than 2mm.
• Check and ensure that all fastening screws, bolts and nuts are securely tightened
prior to operating the tool.
• Never use an object to slow or stop the sharpening or grinding wheel whilst in motion.
• Ensure the eye shields and tool rests are properly adjusted.
•Always use the eye shields and tool rests.
• Don’t use sharpening or grinding wheels for cutting purposes.
•Ensure the wet & dry bench grinder speed doesn’t exceed the operating speed
marked on replacement wheels.
Remove the tool and contents from within the carton. Sit the tool down on a table or
bench with the switch side facing towards you. Ensure the tool is disconnected from
the power supply during assembly and when making adjustments.
Refer to diagram on page 1
Eye Shields
1. Assemble eye shields (2) by placing the raised metal sides of the eye shield
bracket (1) to the wheel guard (4) aligning the hole in the wheel guard (4) and the
slot in the eye shield bracket (1).
2. Feed one of the screws supplied towards you through the hole in the wheel guard
(4) and then through the slot in the eye shield bracket (1). Place a flat washer and
spring washer over the threaded end of the screw and secure with a nut.

the tool rest (5) in the direction of the on/off switch (11). Place a flat washer and
star washer over the threaded end of the bolt and secure by fastening on tool
rest adjusting knob (8).
3. For the tool rest (5) to work effectively, it should be no more than 1.6mm away
from the grinding wheel (3). This will also aid in the deflection of stray sparks.
Note: As the wheel wears with use adjust the tool rest accordingly.
Mounting holes
For extra stability, we recommend securing the wet & dry bench grinder using the
mounting holes (9) provided on the corners of the base. Secure to a bench or table
by using bolts (not supplied).
Changing Grinding Wheel
Disconnect the wet & dry bench grinder from the power supply.
Note: Visually inspect wheels for damage or defects prior to fitting.
1. Remove the eye shield (2) and tool rest (5) from the dry grinding wheel (3) side
of the tool.
2. Loosen and remove the 3 sets of screws, flat washers, spring washers and nuts
that secure the wheel guard cover (7). Remove the wheel guard cover (7).
3. You will need to use a shifting spanner or socket wrench to loosen the wheel
lock nut. Remove the grinder wheel nut by rotating the nut anti-clockwise. Use
one hand to lock the wheel in place and the other to loosen the nut. Remove
the nut, outer flange and old wheel.
4. Ensure the new wheel is secured and rotates freely before proceeding.
5. Re-assemble the wheel guard cover (7) eye shield (2) and tool rest (5).
6. Switch on the bench grinder and ensure that the wheel runs in alignment
before commencing use.
OPERATION

Changing Wet Sharpening Wheel
1. Drain water trough (14).
2. Remove 3 screws securing the water trough (14).
3. Remove the water trough (14) from the tool.
4. Remove the nut retaining the wet sharpening wheel (15) with an 18mm spanner by
turning the nut anti-clockwise.
5. Remove the nut, flanges, and wet sharpening wheel (15) from the tool.
6. Clean dust and debris from flanges and shaft before fitting the replacement wet
sharpening wheel.
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.
On/Off Switch
Turn the wet & dry bench grinder on by pushing the On/Off switch (11) to the “I” (On)
setting. Once depressed it will remain on. Turn the wet & dry bench grinder off by
pushing the On/Off switch (11) to the “O” (Off) setting.
Dry Bench Grinder Operation
Switch the wet & dry bench grinder on and stand to one side while the wet & dry
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.
