4. Ensure that mounted wheels and points are fitted
in accordance with the manufacturer’s instructions.
Ensure that the depressed center wheel to be utilized
is the correct type and free of cracks or surface
defects. Also ensure that the depressed center wheel
is properly mounted and the wheel nut is securely
tightened, Refer to the section on “ASSEMBLING
AND DISASSEMBLING THE DEPRESSED CENTER
WHEEL”
Ensure that blotters are used when they are provided
with the bonded abrasive product and when they
are required.
Do not use separate reducing bushings or adaptors
to adapt large hole abrasive wheels.
For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
Do not use cutting off wheel for side grinding.
5. Conducting a trial run
Ensure that the abrasive products is correctly
mounted and tightened before use and run the tool
at no-load for 30 seconds in a safe position, stop
immediately if there is considerable vibration or if
other defects are detected.
If this condition occurs, check the machine to
determine the cause.
6. Confirm the push button.
Confirm that the push button is disengaged by
pushing push button two or three times before
switching the power tool on (See Fig. 6).
7. Fixing the side handle.
Screw the side handle into the gear cover.
PRACTICAL GRINDER APPLICATION
1. Pressure
To prolong the life of the machine and ensure a
first class finish, it is important that the machine
should not be overloaded by applying too much
pressure. In most applications, the weight of the
machine alone is sufficient for effective grinding.
Too much pressure will result in reduced rotational
speed, inferior surface finish, and overloading which
could reduce the life of the machine.
2. Grinding angle
Do not apply the entire surface of the depressed
center wheel to the material to be ground. As
shown in Fig. 5, the machine should be held at an
angle of 15° – 30° so that the external edge of the
depressed center wheel contacts the material at an
optimum angle.
3. To prevent a new depressed center wheel from
digging into the workpiece, initial grinding should
be performed by drawing the grinder across the
workpiece toward the operator (Fig. 5 direction B).
Once the leading edge of the depressed center
wheel is properly abraded, grinding may be
conducted in either direction.
4. Precautions immediately after finishing operation
The wheel continues to rotate after the tool is
switched off.
After switching off the machine, do not put it down
until the depressed center wheel has come to a
complete stop. Apart from avoiding serious
accidents, this precaution will reduce the amount
of dust and swarf sucked into the machine.
NOTE:
䡬 To prevent injuries, this product has a function that
prevents unexpected motor rotation when the battery
is inserted. The motor will not run if the battery
is inserter while the switch is still ON. After installing
the battery, turn the switch off and then back on
again.
䡬 The G14DSL model is equipped with a protection
function that will shut down the tool in the event
of an overload.
Should the tool shut down due to an overload, turn
the power off and then turn it back on again.
CAUTIONS
䡬 Check that the work piece is properly supported.
䡬 Ensure that ventilation openings are kept clear when
working in dusty conditions.
If it should become necessary to clear dust, first
disconnect the tool from the mains supply (use non-
metallic objects) and avoid damaging internal parts.
䡬 Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite flammable
substances.
䡬 Always use eye and ear protection.
Other personal protective equipment such as dust
mask, gloves, helmet and apron should be worn
when necessary.
If in doubt, wear the protective equipment.
䡬 When the machine is not use, the battery should
be disconnected.
5. About Remaining Battery Indicator
When pressing the remaining battery indicator
switch, the remaining battery indicator lamp lights
and the battery remaining power can be checked.
(Fig. 7) When releasing your finger from the
remaining battery indicator switch, the remaining
battery indicator lamp goes off. The table 4 shows
the state of remaining battery indicator lamp and
the battery remaining power.
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE:
䡬 Do not give a strong shock to the switch panel or
break it.It may lead to a trouble.
䡬 To save the battery power consumption, the
remaining battery indicator lamp lights while
pressing the remaining battery indicator switch.
State of lamp Battery Remaining Power
The battery remaining power
is enough.
The battery remaining power
is a half.
The battery remaining power
is nearly empty.
Re-charge the battery soonest
possible.
