1.11 Operation
Hold head in air or place it on soft surface when starting
motor. This will prevent it from bouncing on hard surfaces
which could damage bearings. During use, insert the
head quickly into the mix and then pull it out slowly. Rapid
removal is the main cause of poor concrete consolida-
tion. For best results submerge head completely and try
to establish a symmetrical pattern for inserting and
removing the head.
Avoid sharp bends in the shaft. This can create hot spots.
When moving around jobsite do not drag head and shaft
on ground.
Avoid touching forms and rebars when inserting head in
mix. This can transmit vibration to other areas of the mix
which may already be setting.
CAUTION:
DO NOT
run the motor with the head out of
the mix for long periods of time. This can cause the
bearings to overheat.
For more detailed information on the use, selec-
tion and application of WACKER equipment for
concrete consolidation, order Wacker publication
WCW 982 “CONCRETE CONSOLIDATION”.
1. Apply pipe sealant to threads on head
(c)
. Attach
head onto end of flexshaft
(left hand thread)
and
tighten using a wrench.
2. The shaft is attached to motor using a quick discon-
nect coupler. The coupler may vary depending on the
type of shaft being used. All new WACKER flexshafts
come equipped with a coupler and do not require any
additional coupling device. Refer to page 3-4 for
shafts equipped with couplers.
If you are using a shaft from another manufacturer, or
are attaching an older WACKER shaft, refer to page
3-7 to order the correct coupling to use. If a coupler
must be installed on the shaft, apply pipe sealant
(f)
to threads before assembling.
3. Lubricate shaft core. See 1.15
Lubricating Shaft.
4. To attach shaft to motor, pull adapter pin
(g)
on motor
up and slide coupler in place. Rotate coupler until pin
falls into coupler socket.
