Functional Description - Makita GD0800C Instruction Manual

b) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such blades
create frequent kickback and loss of control.
d) Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direction
as the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the
bit to climb out of the work and pull the tool in the
direction of this feed.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications.
b) Do not position your hand in line with and
behind the rotating wheel. When the wheel, at
the point of operation, is moving away from your
hand, the possible kickback may propel the spin-
ning wheel and the power tool directly at you.
Additional safety warnings:
21. The tool is intended for use with bonded abra-
sive wheel points (grinding stones) permanently
mounted on plain, unthreaded mandrel (shanks).
22. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
23. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
24. Use the specified surface of the wheel to per-
form the grinding.
25. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other per-
sons or flammable materials.
26. Do not leave the tool running. Operate the tool
only when hand-held.
27. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
28. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
29. Check that the workpiece is properly supported.
30. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-cir-
cuit breaker (30 mA) to assure operator safety.
31. Do not use the tool on any materials contain-
ing asbestos.
32. Always be sure you have a firm footing. Be
sure no one is below when using the tool in
high locations.

WARNING: DO NOT let comfort or familiarity
with product (gained from repeated use) replace
strict adherence to safety rules for the subject
product. MISUSE or failure to follow the safety
rules stated in this instruction manual may
cause serious personal injury.
FUNCTIONAL
DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function
on the tool.
Switch action
► Fig.1: 1. Slide switch
CAUTION:
• Before plugging in the tool, always check to
see that the slide switch actuates properly and
returns to the "OFF" position when the rear of
the slide switch is depressed.
To start the tool, slide the slide switch toward the "I
(ON)" position. For continuous operation, press the
front of the slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
Speed adjusting dial
► Fig.2: 1. Speed adjusting dial
The tool speed can be changed by turning the speed
adjusting dial to a given number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the
direction of number 5. And lower speed is obtained
when it is turned in the direction of number 1.
Refer to the table for the relationship between the num-
ber settings on the dial and the approximate tool speed.

3-4 17,000 - 24,000
4-5 24,000 - 28,000
CAUTION:
• If the tool is operated continuously at low
speeds for a long time, the motor will get over-
loaded, resulting in tool malfunction.
• The speed adjusting dial can be turned only as
far as 5 and back to 1. Do not force it past 5 or
1, or the speed adjusting function may no longer
work.
