Speed adjusting dial
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.
Additionaly, when the load on the tool exceeds admissible levels, power to the motor is reduced to protect the motor
from overheating. When the load returns to admisible levels, the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
Opening or closing of water lever
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.

CAUTION:
• Always be sure that the side grip is installed securely before operation.

Remove one of the screws which secure gear housing and head cover then screw the side grip on the tool.
