Functional Description - Makita 9564PC Instruction Manual

d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
e) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the
wheel.
f) Use extra caution when making a "pocket
cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.
21. Safety Warnings Specific for Sanding Opera-
tions:
a) Do not use excessively oversized sanding
disc paper. Follow manufacturers recommen-
dations, when selecting sanding paper.
Larger sanding paper extending beyond the
sanding pad presents a laceration hazard and
may cause snagging, tearing of the disc or kick-
back.
22. Safety Warnings Specific for Wire Brushing
Operations:
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) If the use of a guard is recommended for wire
brushing, do not allow interference of the
wire wheel or brush with the guard. Wire
wheel or brush may expand in diameter due to
work load and centrifugal forces.
23. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced wheels.
24. Be careful not to damage the spindle, the flange
(especially the installing surface) or the lock nut.
Damage to these parts could result in wheel
breakage.
25. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
26. 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.
27. Use the specified surface of the wheel to per-
form the grinding.
28. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
29. Do not leave the tool running. Operate the tool
only when hand-held.
30. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
31. Always be sure that the tool is switched off and
unplugged or that the battery cartridge is
removed before carrying out any work on the
tool.
32. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.

33. Do not use separate reducing bushings or adap-
tors to adapt large hole abrasive wheels.
34. Use only flanges specified for this tool.
35. 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.
36. Check that the workpiece is properly supported.
37. Pay attention that the wheel continues to rotate
after the tool is switched off.
38. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
39. Do not use the tool on any materials containing
asbestos.
40. Do not use water or grinding lubricant.
41. 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.
42. When use cut-off wheel, always work with the
dust collecting wheel guard required by domes-
tic regulation.
43. Cutting discs must not be subjected to any lat-
eral pressure.
SAVE THESE INSTRUCTIONS.
WARNING:
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.
Shaft lock (Fig. 1)
CAUTION:
• Never actuate the shaft lock when the spindle is mov-
ing. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the switch lever actuates properly and returns to the
"OFF" position when released.
• Do not pull the switch lever forcibly without pushing in
the lock-off lever.
To prevent the switch lever from accidentally pulled, a
lock-off lever is provided. To start the tool, pull the lock-off
lever toward the operator and then pull the switch lever.
Release the switch lever to stop.
Speed adjusting dial (Fig. 3)
The rotating 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 below table for the relationship between the
number settings on the dial and the approximate rotating
speed.
