Thank you for your selection of Flextool equipment.
Flextool have specialised in the design and manufacture
of quality products since 1951.

We have taken care in the design, manufacture and test­ing of this product. It is covered by a six month warran­ty. Should service or spare parts be required, prompt
and efficient service is available from our branches.

General Safety Instructions for the Operation of
Power Equipment

The goal of Flextool is to produce power equipment that
helps the operator work safely and efficiently. The most
important safety device for this or any tool is the opera­tor. Care and good judgement are the best protection
against injury. All possible hazards cannot be covered
here, but we have tried to highlight some of the impor­tant items, individuals should look for and obey Caution,
Warning and Danger signs placed on equipment, and
displayed in the workplace. Operators should read and
follow safety instructions packed with each product.

Learn how each machine works. Even if you have previ­ously used similar machines, carefully check out each
machine before you use it. Get the "feel" of it and know
its capabilities, limitations, potential hazards, how it
operates, and how it stops.

Heavy duty concrete vibrators, 28 mm - 60 mm dia.
Submersible pumps, up to 50 mm discharge.

This portable drive unit is designed to power flexshaft
drive submersible pumps and model VP (pendulum)
vibrators. A quick action 60 mm diameter flexible shaft
coupling with aluminium alloy housing, rotary trigger
latch and hardened 45 mm 3-tooth dog drive enable
ease of use by allowing the operator to simply engage or
disengage the flexible shaft coupling, to facilitate either
a change of position or a change of flexshaft driven
device.

Bell housing / Rotary trigger

Is mounted directly to the motor and enables quick con­nection between the coupling and the 3-tooth dog drive
mounted on the crankshaft. The rotary trigger latch
assures a positive engagement between drive dogs.

Motor

The motor is controlled by an on/off switch or push but­ton switch mounted on the motor below the fuel tank.

To STOP the machine TURN the switch to the OFF posi­tion or PRESS the push button in until the motor stops.

Honda, Robin and Vanguard motors are fitted with an oil
sensor device that will stop the motor or prevent starting
when the crankcase oil level falls below a safe level.

The motor speed is controlled by a throttle lever mount­ed below the air cleaner. The throttle should be adjust­ed to the maximum position when operating a flexible
shaft driven device.

NEVER allow any person to operate a machine without
adequate instruction.

ENSURE all 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

KEEP hands and feet clear of rotating and moving parts
as they will cause injury if contacted.

BE CAREFUL not to come in contact with the muffler
when the engine is hot, since it can cause severe burns.

ENSURE that the motor operation switch is in the OFF
position and the spark plug ignition lead is disconnected
before removing guards or making adjustments.

ENSURE both the machine and the operator are stable
by setting up on level terrain and the machine will not
move or fall while in operation or unattended.

DO NOT leave the machine in operation while it is unat­tended.

DO NOT increase the governed no-load motor speed
above 3,000 r/min on an engine with a power output of
less than 5.6 kW, or a flexible shaft smaller than 16 x
38mm. Any increase may result in personal injury and
damage to the machine.

KEEP bystanders and animals clear of the work area.

APPLICATIONS

INTRODUCTION

ENSURE that repairs to the motor and machine 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 refuelling. Spilled petrol or petrol vapour may
ignite. If spillage occurs, ensure that the area is dry
before starting the motor.

ENSURE that the fuel tank cap is securely fitted after
refuelling.

! 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.

! ADDITIONAL HAZARDS

Slip/Trip/Fall is a major cause of serious injury or death.
Beware of excess hose, the flexible shaft and water left
on the walking or work surface.

DO NOT allow waste water to accumulate under foot.
Exercise caution and ensure that the perimeter of ele-

vated formwork or platforms is protected.
Exercise care when working in the vicinity of unprotect-

ed holes or excavations

For information on correct starting procedures refer to
the engine manufacturers operation manual.

Before engaging the flexshaft with a petrol drive unit
start the motor using the recoil starter, increase the
speed to full throttle and allow it to warm up for a few
minutes. (If the motor is fitted with an on/off switch this
must first be turned ON before starting.)
Stop the motor.
Turn the bell housing trigger 180 degrees. Insert the

flexshaft coupling fully into the housing of the drive unit
and release the trigger. Push the coupling into the hous­ing and twist the flexible shaft until the drive dogs are
fully engaged and the trigger returns to the horizontal
position.
The motor may now be started

Drive units should be operated on a level surface. If the
surface is not level the drive unit should be restrained to
ensure that it does not move due to vibration or the
weight of a pump and hose or vibrator.

Check the condition of the drive dog regularly and that
the three tooth drive dogs are fully meshed. The posi­tion of the drive dog on the crank shaft is critical and
should also be checked. The correct distance from the
face of the teeth to the face of the bell housing is 73 mm
(2.875 inches).

Worn coupling housings and poorly operating triggers
together with worn grooves in the shaft coupling will lead
to a shorter operating life and should be replaced before
they have worn excessively.

Check the oil level in the petrol motor crankcase daily.

Change the oil in the petrol motor crankcase regularly to
minimise wear.

Inspect, clean and/or replace the motor air cleaner reg­ularly, particularly when operating in a dusty environ­ment.

Inspect, clean and/or replace the spark plug regularly.

Keep the unit clean and free of concrete residue.
Ensure the cooling fins on the motor are kept unob-

structed.

SYMPTOM POSSIBLE CAUSES AND CORRECTION

Motor will not start. • Check the ON/OFF switch to ensure that it is switched ‘ON’.

• Check the fuel supply.

• If a Honda or Robin motor is fitted check the crankcase oil level as an oil
sensor device is fitted to these motors which prevents starting and stops
the motor when the oil level is low.

• Ensure the spark plug ignition lead is connected.

• Check the carburettor jet and bowl to ensure they are clean.

Motor stops. • Check the fuel supply.

• Check that the fuel cock is turned on.

• Check the condition of the air filter.

• Check the oil level.

Motor lacks power. • Check the condition of the air filter.

• Check the condition of the spark plug.
