ASSEMBLY
If the unit was supplied unassembled the following must be completed prior to
operation:
The unit is supplied with a flexible shaft disconnected from the motor unit.
To attach the flexible shaft, place the threaded ferrule end of the flexible
shaft approximately 20 mm from the coupling housing. Engage the squared end of
the flexible shaft core assembly into the squared seal sleeve adaptor.
The threaded fertile end of the flexible shaft may now be screwed into the
motor adaptor. Rotate the ferrule end of the flexible shaft in an anti-
clockwise direction to engage the left-hand thread. Once tightened by hand use
multigrip pliers to ensure the ferrule is tightened sufficiently to stop it
from working loose and coming detached during operation. A 1 Nye container of
Honda 10W/30 engine oil is included with the unit. The engine oil capacity is
100 ml. To add oil place the unit on a level surface and remove the oil filler
cap. Add oil until the oil level reaches the edge of the oil filler neck &
reinstall the oil filler cap. Fuel may now be added and the unit is ready for
operation.
FUNCTION AND CONTROLS
DRIVE UNIT
This portable drive unit is designed to power flex shaft drive, eccentric
vibrators.
The motor is controlled by an ON/OFF push button which is mounted below the
throttle lever on the handle.
The motor speed is controlled by a throttle lever mounted on the handle A
centrifugal clutch is fitted to the motor which disengages the drive to the
vibrator when the motor is idling.
The clutch operates automatically and requires no adjustment.
The motor is a 4-stroke unit and must only be used with unleaded petrol.
VIBRATOR
This vibrator is designed for the compaction of concrete by immersion of the
vibrator head. Compaction improves the strength and finish of concrete by
driving out entrapped air.
High-frequency vibration allows the efficient compaction of low slump concrete
mixes.
The vibrator head is driven by a rotating flexible drive shaft that transmits
the drive from the drive unit.
The vibrator head uses an eccentric mass to produce vibration. Ball bearings
support the rotor at each end.
HAZARDS AND RISKS NEVER
allow any person to operate equipment without adequate instruction. ENSURE NI
operators read, understand, and follow the operating instructions. SERIOUS
INJURY may result from improper or careless use of this machine!
MECHANICAL HAZARDS
DO NOT operate the machine unless all protective guards are in place.
ENSURE that the motor operation switch is in the OFF position and the spark
plug ignition lead is disconnected before removing the guards or making
adjustments.
KEEP hands and feet clear of rotating and moving pads as they will cause
injury if contacted.
DO NOT leave the equipment in operation while it is unattended.
EXERCISE CARE when handling vibrators. Exposure to vibration or repetitive
work actions may be harmful to hands and arms.
DO NOT hold the vibrator shaft in your hands while it is running. Hold the
vibrator by the “D” handle & use the supplied carry strap to help isolate your
hands from the vibration.
NEVER stand on the vibrating head while it is operating.
DO NOT place your foot on the vibrator head while it is running unless it is
done momentarily and the vibrator head is resting on resilient support such as
a car tire.
BE CAREFUL not to come in contact with the muffler when the engine is hot
since it can cause severe burns. ENSURE that repairs to machinery are carried
out by COMPETENT personnel.
! FIRE & EXPLOSION HAZARDS
PETROL is extremely flammable and explosive under certain conditions.
ENSURE that petrol is only stored in an approved storage container.
DO NOT refuel the motor while it is in operation or hot.
DO NOT refuel the motor in the vicinity of sparks, a naked flame or a person
smoking.
DO NOT overfill the fuel tank and avoid spilling petrol when refueling.
Spilled petrol or petrol vapor may ignite. If spillage occurs, ensure that the
area is dry before starting the motor.
Motor vibrations can cause an improperly tightened fuel cap to loosen or come
off and spill quantities of fuel. In order to reduce the risk of fuel spillage
and fire, tighten the fuel cap by hand with as much force as possible.
To reduce the risk of serious injury from burns, never attempt to refuel the
unit until it has been stopped & completely removed from the operator.
! CHEMICAL HAZARDS
DO NOT operate or refuel a petrol motor in a confined area without adequate
ventilation.
CARBON MONOXIDE exhaust gases from internal combustion motor-driven units can
cause death in confined spaces.
! NOISE HAZARDS
EXCESSIVE NOISE can lead to temporary or permanent loss of hearing.
WEAR an approved hearing protection device to limit noise exposure. as
required by Occupational Health and Safety regulations. Noise levels in excess
of 85dB(A) may be produced by engines and vibrators.
PROTECTIVE CLOTHING
ALWAYS wear protective clothing and footwear to prevent the skin from coming
into contact with wet concrete.
PROTECTIVE FOOTWEAR should be worn to reduce injuries from penetration through
the sole, contact with cutting objects, slipping, contact with wet concrete,
and electrical hazards.
GOGGLES for eye protection may also be necessary.
USE waterproof protection for hands and knees (if kneeling) when concreting.
If your clothing becomes wet from concrete contact make sure you change the
clothing. Do not walk about waiting for it to dry.
USE GLOVES when handling and inspecting the flexible shaft outer casing.
Excessive wear of the rubber cover can expose the wire braided reinforcement,
allowing it to project and cause injury.
ADDITIONAL HAZARDS
To reduce the risk of injury from loss of balance, start the motor with the
unit on a flat level surface, and only pick up the unit when the engine is
idling. Slip/Trip/Fall is a major cause of serious injury or death. surface.
Exercise caution and ensure that the perimeter of elevated formwork or
platforms is protected. Exercise care when working in the vicinity of
unprotected holes or excavations
OPERATION
To start the motor, place the unit on a flat level surface, and only pick up
the unit when the engine is idling.
To start the motor turn the engine switch to the ON position.
To start a cold engine, move the choke lever to the closed position To restart a warm engine, leave the choke lever in the OPEN position.
Press the priming pump several times until a flow in the fuel return tube is
visually noticed. Pull the starter grip lightly until you feel resistance
while holding the unit steady, then pull briskly. Return the starter grip
gently.
If the choke lever is in the CLOSED position, gradually move it to the OPEN
position as the engine warms up. The idle-up function helps the engine start
by opening the throttle valve in the carburetor moderately when the engine
won’t start.
- Hold down the throttle interlock.
- Pull the throttle trigger.
- Push the idle knob, then release the throttle trigger and the interlock.
- Start the engine NOTE: This function must not be used when vibrating.
Always operate the unit at full throttle. This will ensure correct concrete
compaction and avoid damage to the drive mechanism.
Be careful starting and or revving the unit on loose gravel as it may be
sucked into the flywheel cooling fins causing damage to the unit. Information
regarding the compaction of concrete using immersion vibrators is available in
a FLEXTOOL FACT SHEET.
Avoid sharp bends in the flex shaft, particularly when it is in use.
Do not use an eccentric-type immersion vibrator head as an external vibrator
by applying it to the outside of the formwork. Do not operate the vibrating
head out of concrete for extended periods.
Do not leave it running while you wait for fresh supplies of concrete to be
placed. Vibrator heads are designed to be cooled by the concrete in which they
are immersed.
CARE AND PREVENTIVE MAINTENANCE
Keep the unit clean and free of concrete residue.
Check the oil level in the engine crankcase daily, it should reach the edge of
the oil filler neck. The engine oil capacity is only 100 ml and running the
engine with a low oil level will cause serious engine damage.
Vibrators must be handled with care, and be properly maintained in order to
avoid unnecessary breakdowns. Check regularly for signs of wear and rectify
any faults immediately. The exterior of the flex shaft and the vibrator head
is subject to abrasion and wear. If the vibrator is operated unchecked,
concrete will eventually enter the vibrator head or the flex shaft.
Naturally, the cost of repairing, a vibrator that has been allowed to
deteriorate in this way will be greater. Regular inspection of the vibrator
and the flexible shaft will avoid these problems.
Check the flexible shaft for kinks and external damage by laying it out
straight on a workbench or the floor. Although it still operates, a badly
kinked flexible shaft may result in a broken inner core.
Check the outer casing rubber cover for damage where it enters the ferrule at
the vibrator head. Damage is caused by operators using a crane to retrieve a
vibrator trapped in concrete reinforcing bars.
SERVICE
Replace the oil in the motor crankcase regularly with Honda 10W/30 oil.
The air cleaner element fitted is a wet foam type. Service the air cleaner
element regularly by washing the element in a nonflammable solvent and letting
it dry thoroughly. Soak the element in clean engine oil, squeeze out the
excess oil and reinstall the air cleaner element.
A fuel tank strainer is fitted to the unit. A clogged filter may cause poor
engine performance requiring the fuel filter to be removed from the fuel tank
and cleaned.
Inspect, clean, and/or replace the spark plug regularly.
CLEANING AND STORAGE
It is advisable to wash the vibrator head and flex shaft with clean water
after use each day and before storing. This will ensure that concrete does not
accumulate on the exterior.
Ensure the cooling fins on the motor are kept unobstructed.
