Operation - Makita PW5000CH Betriebsanleitung

Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the slide switch actuates properly and returns to the "O
(OFF)" position when the rear of the slide switch is
depressed.
• Switch can be locked in "I (ON)" position for ease of
operator comfort during extended use. Apply caution
when locking tool in "I (ON)" position and maintain firm
grasp on tool.
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. 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.

CAUTION:
• If the tool is operated continuously at low speeds for a
long time, the motor will get overloaded and heated up.
• 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.
Electronic function
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constant even under the loaded condition.
Additionally, when the load on the tool exceeds admissi-
ble levels, power to the motor is reduced to protect the
motor from overheating. When the load returns to admis-
sible levels, the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
Opening or closing of water lever (Fig. 4)
To keep the lever on the tool for water flow open, turn it to
the position A where the water passage will be ready.
Return it to the position B to close.
The amount of water flow can be adjusted by changing
the lever position between the positions A and B.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (handle)
CAUTION:
• Always be sure that the side grip is installed securely
before operation.
Screw the side grip securely on the position of the tool as
shown in the figure. (Fig. 5)
Remove one of the screws which secure gear housing
and head cover, then screw the side grip on the tool.
(Fig. 6)
Installing or removing abrasive disc (Fig. 7 & 8)
Remove all dirt or foreign matter from the pad.
Screw the pad onto the spindle with pressing the shaft
lock.
Attach the disc to the pad so carefully that the edges of
disc and pad overlap each other without protruding.
To remove the abrasive disc, pull off its edge from the
pad.

OPERATION

Polishing operation (Fig. 9)
WARNING:
• To reduce the risk of electric shock, check the tool's
water supply system to ensure there is no damage to
the seals ("o" rings) or hoses. A damaged water supply
system may result in abnormal water flow to the tool,
which could be dangerous.
CAUTION:
• Always wear safety goggles or a face shield during
operation.
• Never switch on the tool when it is in contact with the
workpiece, it may cause an injury to operator.
• Never run the tool without the abrasive disc. You may
seriously damage the pad.
• Be sure to feed water to the abrasive disc during opera-
tion. Failure to do so may cause breakage to the tool.
• The temperature of water to be used should be within
the range of 0°C – 40°C (32°F – 104°F). Use of freez-
ing or hot water beyond this range may cause damage
to the tool.
• The maximum permitted pressure of water supply is
7 bar.
Make sure that the cock is closed. Connect the hose to
the tool. Make sure that water comes out when the water
lever is opened.
Hold the tool firmly. Turn the tool on and then apply the
abrasive disc to the workpiece.
Apply slight pressure only. Excessive pressure will result
in poor performance and premature wear to abrasive
disc.
