Functional Description - Makita PW5000C Manual De Instrucciones

This tool is designed exclusively for connection to an iso-
lating transformer with an output voltage of 110 V. Due to
its use in wet conditions (water connection on the tool),
this tool must never be connected to a power supply with-
out an isolating transformer.
Damages caused by inappropriate tampering with the
plug-in device are not subject to warranty or legal guar-
antee claims.
Contact your specialist supplier for an isolating trans-
former suitable for your tool.

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 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.
