FLEXTOOL OPERATING INSTRUCTIONS
PETROL DRIVE UNIT FDU SERIES

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 elevated
formwork or platforms is protected.
Exercise care when working in the vicinity of unprotected holes or
excavations.
OPERATION
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.
CARE AND PREVENTIVE MAINTENANCE
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.
SERVICE
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.
CLEANING AND STORAGE
Keep the unit clean and free of concrete residue.
Ensure the cooling fins on the motor are kept unobstructed.
