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

Civil: roadways, kerbing, pre cast beams, bridge decks, piers.
Commercial building: strip and raft foundations, stairs, walls, ﬂoors,

driveways, suspended slabs, tilt panels, stack cast panels.
Residential building: ﬂoor stumps, wall cavities, house slabs, wall

footings, paving slabs.
Rural: fence posts, stock troughs and pens.

ASSEMBLY

If the unit was supplied unassembled the following must be

completed prior to operation:
The unit is supplied with the 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 ferrule 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 litre container of Honda 10W/30 engine oil is included with the

unit. 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 ﬂexshaft 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 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 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.
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 parts 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.

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 ﬂexshaft and the vibrator head are subject to

abrasion and wear. If the vibrator is operated unchecked, concrete

will eventually enter the vibrator head or the ﬂexshaft.
Naturally, the cost of repairing, a vibrator which 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 non

ﬂammable solvent and let 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 ﬂexshaft 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.
