INTRODUCTION
Thank you for your selection of Parchem equipment.
Parchem 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. 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 Parchem 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.
APPLICATIONS
Heavy duty concrete vibrators, 28 mm - 60 mm dia. Submersible
pumps, up to 50 mm discharge.
FUNCTION
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.
FUNCTION AND CONTROLS
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.
HAZARDS AND RISKS
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.
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 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.
