Check the following after reassembly:
(1) Check that the tool is properly turned on and off by operating the switch trigger and the on lock function
is activated properly. Also check that the battery cover is smoothly opened and closed.
(2) Check that the operating mode switches between "Normal" and "Power" with the indicator lamp lighting
as shown in the table below and vibration frequency (sound of vibration) changes according to the
operating mode each time the mode switch on the switch panel is pressed.

(3) Check that the battery terminal moves smoothly between housings (A) and (B) without rattling.
(4) Check that the hose gland is not loose after turning on and off the switch several times.
The no-load current value should be 3.5±1 A (39.6 VDC — equivalent to the voltage of a fully charged
battery) after no-load operation for 5 minutes in the power mode.
NOTE: The flexible shaft may vibrate heavily with loud noise and the no-load current may be about
6 A during no-load operation after reassembly. This is due to the unbalanced flexible shaft
and is not a fault. Heavy vibration or loud noise may be stopped after a while during operation.
If it still persists, bend the flexible shaft or turn on and off the trigger switch to stabilize the
rotation of the flexible shaft.
