INTRODUCTION
Thank you for your selection of equipment supplied by Parchem,
we have specialised in quality products for over 50 years.
Should service or spare parts be required, prompt and efficient
service is available from our branches.
It is essential that the operator takes particular care to use the
machine properly and minimise any potential hazards to himself or
others. We recommend that all operators and service personnel
read, understand and follow this manual.
Applications
„„ Asphalt levelling & grooving
„„ Carpet backing removal
SPS Machine
The SPS is a walk behind machine, basically designed to be a
scarifier, but by using different cutters, arranged in a variety of
manners on the cutter heads or cages, a broad range of textures
and finishes can be produced.
This multi-purpose machine will produce results ranging from
scabbier to scarifier.
Cage / Drum Depth Control Knob
Rotate clockwise to raise unit and counter clockwise to lower unit.
Drive belt
Tension of the drive belt is adjustable. Loosen the four nuts on
the bolts which secure the motor to the base plate, Adjust the set
screws which bear against the motor crankcase to achieve the
required belt tension.
Motor
The motor speed is controlled by a remote throttle lever which is
mounted above the air cleaner. To STOP the machine press the
push button mounted on the handle or below the fuel tank.

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.
ENSURE that the electricity supply to the motor is disconnected/
isolated 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.
ENSURE that the area to be milled does not contain any “live”
electrical cables, gas, water or communication services which may
be damaged by the action of the unit.
EXERCISE CARE when operating unit. Exposure to vibration or
repetitive work actions may be harmful to hands and arms.
NEVER stand on the unit while it is operating.
KEEP bystanders and animals clear of the work area.
WEAR snug fitting clothing and ensure no clothing, hair or jewellery
can become entangled in machine.

! FIRE & EXPLOSION HAZARDS
PETROL or diesel is extremely flammable and explosive under
certain conditions.
ENSURE that petrol or diesel is only stored in an approved storage
container away from source of ignition.
DO NOT refuel the motor while it is in operation or hot.
DO NOT refuel the motor in the vicinity of ignition source such as
sparks, a naked flame or a person smoking.
DO NOT over fill 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.
Ensure fire extinguisher is readily available for use.
! CHEMICAL HAZARDS
DO NOT operate or refuel a petrol or diesel motor in a confined area
without adequate ventilation.
CARBON MONOXIDE exhaust gases from internal combustion
motor driven units can cause death in confined spaces.
Check TLV (Threshold Limit Value) and oxygen content of area safe
for operation.
! NOISE HAZARDS
EXCESSIVE NOISE can lead to temporary or permanent loss of
hearing.
WEAR an approved hearing protection device to limit noise
exposure. As required by Occupational Health and Safety
regulations.
! PROTECTIVE CLOTHING
ALWAYS wear approved hearing protection. Protective dust mask,
goggles, footwear and clothing may also be necessary.
! ADDITIONAL HAZARDS
Surface prep machines are heavy and should be positioned by two
people of appropriate strength. Using the lifting handles provided
on the machine, along with correct lifting techniques.
Slip/Trip/Fall is a major cause of serious injury or death. Beware of
the power lead and dust left on the walking or work surface and
uneven or slippery surfaces.
Exercise care when working in the vicinity of unprotected holes or
excavations
BE CAREFUL when operating unit around pipes sticking out of the
floor or other obstacles. Should the cage/drum catch on these,
serious damage to the machine or harm to the operator may result.
operation
Use unleaded grade petrol and ensure that the fuel is free from
contamination.
OPERATING SUGGESTIONS
With any machine there are tricks to using them that make
them work more efficiently. Never force the cutter head into the
surface to a point where the machine starts to bounce. This will
minimise results and do more damage to the machine than the
work surface. Also, excessive vibrations will make it awkward, if
not uncomfortable, for the operator to handle the machine. Let
the cutters do the work, but make sure you have the best cutter/
cage assembly for the job. The key to effective usage of any
tool, is operator comfort and familiarity with the tools capabilities.
Experiment and try different combinations of cutters and cage set
ups for different applications. Specific set ups described may be
adjusted as needed for the specific use.
Working the machine in a figure 8 pattern, when milling misaligned
concrete slabs or joints will produce more aggressive removal of
material. The cutters will work against any grooves and tend to
produce more consistent and faster removal of material. Moving the
machine in a straight line tends to create grooves that the cutters
will follow. The tungsten carbide tipped cutters produce the longest
life in milling applications and should be considered as the best
choice, in spite of the higher initial costs. Your time is expensive
and when you have to take time to change cutters or even cutter
assemblies you are not using the machine to make you money.
When using the SPS to mill concrete, the tendency is to produce
low spots. Work the left side or belt guard side, riding on the high
side of the cut, if possible. Regularly check that the’ drive pulley is
aligned properly and secured to the drive shaft.
When using any cutter cage assemblies, try to maintain equal
height adjustment of the cage against the work surface. Always let
the cutters do the work.
Grooving set ups are possible with the SP8 in as many
configurations as you need. The normal set up of the R123 uses
cutlers spaced with 25mm centres braced by tension springs.
They could also be set up with other centres, but bear in mind that
they must always be tensioned to maintain the path you require.
Checker board effects are possible by working the machine at 90
degrees to the path first established.
When using the edger attachment for crack chasing try the
following method. Mark the front of the edger with a chalk guide
line to correspond to the starting point of the crack. Lower the head
into the crack and push the machine forward along the fault line
using the chalk mark as the steering guide. Using carbides gives
the longest life, but B-2 and B-3 cutters may also be used in the
set up. Always tension the cutters in the cage with spring load to
maintain a consistent path.
care and preventive maintenance
Check the oil level in the motor crankcase daily.
Inspect the rubber anti vibration mounts for wear or deterioration.
service
Change the oil in the motor crankcase regularly to minimise wear.
Inspect, clean and/or replace the motor air cleaner regularly,
particularly when operatingi n a dusty environment.
Inspect, clean and/or replace the spark plug regularly.
Check vee belt tension, wear and that it is running true, adjust or
replace as required.
Check all fasteners for tightness as the machine is subject to
vibration.
