GENERAL INFORMATION
The FX high-frequency vibrator is a bar type vibrator
that is inserted directly into fresh concrete (freshly-mixed
concrete) to provide vibration for concrete consolidation.
For consolidation of fresh concrete, the end of the machine,
after being inserted in the concrete, gives appropriate
vibration directly to the concrete. This helps the concrete
fill in the form without any gap and discharges air bubbles
contained in the concrete, resulting in finely consolidated
beautiful finish of concrete with high strength.
If the power cord is extended, the machine can be used
easily for concrete casting at deep areas or any location
far from the power outlet. Its light weight allows long hours
of operation and handling such as moving of the machine
easily and safely.
The FX vibrator is widely used for general concrete casting
in civil engineering and construction, and is offered in
several types with four different vibration head diameters
ranging from 1.25 to 2.4 inches, hose length of 20 feet, and
a standard cord length of 50 feet.
STRUCTURE
THE FX vibrator has a vibration head that generates
strong vibration at the end. Inside the vibration head, high
frequency motor is directly connected to the eccentric
weight that generates vibration by rotation.
This high-frequency motor is a three phase induction motor
with high frequency power source specification (low voltage:
48V and high frequency: 240Hz).
The wire to run the high frequency motor is connected to
the hose that is connected to the vibration head and the
pipe, then via the power cord to the power plug.The switch
box for turning on/off the high frequency motor is inside the
switch box between the hose and power cord.
TIPS
Keep the bending radius of the flexible hose to a
minimum during use.
CAUTION
When operating the FX vibrator, ALWAYS wear rubber
insulated gloves and boots. Safety glasses and ear
protection are also recommended.
Avoid starting the unit with the vibrator head immersed in
the concrete mix. After the engine has started, immerse
the vibrator head into concrete mix.
Excessive wear to the vibrating head can result from
misuse. DO NOT allow the head to vibrate against already
hardened concrete or steel used for reinforcement.
NEVER drop or knock the vibrator head against any
hard objects. This can damage the eccentric end bell
assembly or bearings contained within the head.
ALWAYS rinse or wipe off any wet concrete before it
dries or hardens on any part of the unit (shaft, or head).
EXTENSION CORDS
When extension cords are used, refer to Table 3 for the
correct size and lengths needed. Using an extension
cord with a wire gauge smaller than or longer than
the recommended size could result in reduced motor
performance and/or damage to the motor or extension
cord due to overheating.
WARNING
Before operating this vibrator, the
operator must read and understand
the contents of the operation manual.
Failure to read this manual may result
in severe bodily harm and damage to
the equipment.
