OPERATION
For information on correct starting procedures refer to the engine
manufacturers operation manual.
Befor
e engaging the flexshaft with a diesel 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. 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 oil level in the motor crankcase daily.
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.
SERVICE
Change the oil in the motor crankcase regularly to minimise wear.
Inspect, clean and/or replace the motor air cleaner regularly,
particularly when operating in a dusty environment.
CLEANING AND STORAGE
Keep the unit clean and free of concrete residue.
Ensure the cooling fins on the motor are kept unobstructed.
