PRE-USE INSPECTION
The following Pre-use inspection must be performed before the start of each work session or after every four hours of use, whichever
is ¿ rst. Please refer to the service section for detailed guidance. If any fault is discovered, the poker must not be used until the fault is
recti¿ ed.
1. Thoroughly inspect the poker for signs of damage. Check components are present and secure.
2. Check the À exible shaft for signs of damage.
The maximum speed for the fl exible shaft poker is 2800 rpm. If the poker is used above this speed, then it

CONNECTION PROCEDURE
Before connecting the poker to the power unit, You must lay the poker out to its full length.
DO NOT connect the poker to the power unit whilst the power unit is operating. This will cause the inner
CAUTION
core to snap thus causing extensive internal damage.
1. To assemble the À exible drive to the power unit, raise the plunger knob on the À ange and insert the
À exible drive end piece connector.
2. On releasing the knob the plunger should locate in the end piece connector.
3. If the plunger fails to locate, rotate the engine crank shaft with the rope start or handle and push the
end piece in.
RECOMMENDATIONS FOR USE OF CONCRETE VIBRATOR
1. Choose the right size of poker for: the size of the job, the spacing of reinforcement, slump of the
concrete and the mix design.
2. It is recommended to have an additional concrete vibrator available.
3. Pour the concrete evenly, into the form work, in 300-500 mm thick layers. Do not use the poker
vibrator to spread the concrete. The operating hose should not be kinked or bent tightly, since this
will increase wear.
4. Vibrate the concrete systematically. Make 300-500 mm vertical insertions at
intervals of 8-10 times the tube diameter. Where possible, push the poker
vibrator about 150 mm into the previous layer of the concrete, this will help obtain
the best bonding between the two layers.
The concrete has been thoroughly vibrated when the surface around the poker is
shiny and no large air bubbles rise to the surface of the concrete. This normally
takes 10-20 seconds at each location of the poker.
5. Withdraw the poker slowly so that the concrete can À ow into the void left by the
poker.
6. Do not push or force the vibrator against the reinforcement. Keep a distance of
70 mm minimum from the walls.
7. Always remove the poker vertically, so the concrete ¿ lls the empty space again.
Do not switch off until the poker is withdrawn completely. The speed of removal is
approximately 8 cm per second. When the vibrator is almost out, extract quickly to avoid shaking the surface.
Do not keep the concrete vibrator out of the concrete for long periods. If you have stopped vibrating the
CAUTION
concrete, turn the poker off.
