Lock-Off Button (Fig. G)
To select Locked/Off, depress the lock-off button
left side of the tool. When changing the position of the lock-off
button, be sure the trigger is released.
To operate the tool, select the ON position by releasing the
trigger switch 1 and depress the control button
side of the tool, as shown in Figure G.
To Operate (Fig. A, F)
Using both hands, as shown in Figure F, firmly hold the
housing 3 of the concrete vibrator while inserting the vibrating
head 4 into the poured concrete. Turn the lock-off control
button to the ON position and depress trigger switch.
For best results, it is usually best to keep the vibrator head
vertical at all times and to avoid side-to-side movement. It is
generally best to insert the vibrator head into the concrete,
turn the vibrator on, then turn it off before pulling the vibrator
head straight out. Move the vibrator head to the next location
and repeat.

e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regular cleaning.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
The charger and battery pack are not serviceable.
Flex Shaft Lubrication
The flex shaft casing is properly lubricated at the factory. It
is recommended for every 100 hours of use, the flex shaft
core be removed and wiped with a clean, dry cloth and high-
temperature grease be applied.
Use caution to avoid dirt and other contaminates from entering
the casing or touching the core when removing and cleaning
the flex shaft core. Avoid low-temperature grease which may
collect at the bottom of the shaft causing leaks.
Do not disassemble vibrator head. The vibrator head is sealed at
the factory and contains a special high-performance lubricant.
Breaking the seal and adding incorrect lubricant will significantly
decrease the performance and life of the tool. If vibrator head
is damaged or needs lubricant, take the tool to a D
authorized service center.
