FUNCTION AND CONTROLS
All references to the right and left side of the machine are as viewed
by the operator in the working position.
Depth of cut
The blade cutting depth (max. 125mm)is controlled by adjusting the
height of the bolt mounted below the swing arm belt guard on the
left hand side.
Water supply
Diamond blades must be kept cooled whilst cutting.
Water keeps the blade cool, removes cuttings and keeps dust
down. A continuous flow of water is critical to ensure that no blade
damage occurs whilst cutting.
Water is directed to both sides of the blade, the supply is controlled
by a stop cock at the rear of the blade guard. The water supply is
provided by connection to the town supply or the optional water
pump.
For town water connection a flexible hose with a quick action
connector may be attached to the machine.
When using the optional water pump, the tray acts as a reservoir
and water is recirculated.
TABLE
The table has four rollers, which run along the edge of the tray.
LEGS
The scissor legs are removable and fold up for transport.
The tray should be secured to the legs by inserting the long pin
attached to the return spring at the rear of the unit through the lugs
on the tray and the scissor legs.
FOOT PEDAL
The unit can be operated by foot pedal operation or the head can
be secured in a stationary position by the lock down adjusting
bracket at the back of the saw.
The foot pedal is engaged in the machine by the use of the short
securing pin attached to the lug on the rear of the unit. To aid
transportation the foot pedal can be removed from the legs.
CUTTING BLADE
A “diamond” blade with diamond impregnated segments on its
outer edge should be used. Slots in the blade accommodate
thermal expansion of the segments, flexing of the blade under
pressure and allow water cooling.
DRAIN HOLE
The drain hole is located in the bottom right of the tray at the rear.
It is sealed by a removable rubber plug which permits draining,
flushing and cleaning.
POWER SUPPLY
Electrical power is controlled by an ON/OFF switch which is
mounted on the front of the motor. A thermal overload protection
device is fitted to the single phase motor. It is located below the
switch. If the motor stops, switch the machine OFF, determine the
cause of the problem, allow the motor to cool, then press the reset
button. If the motor fails to start, check the power supply, fuses or
circuit breaker and leads.
DRIVE BELT
Tension of the drive belt is adjustable. Loosen the four bolts that
secure the motor to the frame. Tighten the bolts after achieving the
desired belt tension.
ACCESSORIES
DIAMOND BLADE
When purchasing diamond blades seek the guidance of your
supplier. Select a grade of blade to suit the material to be cut, e.g.
bitumen, clay paving bricks and reinforced concrete, each requires
a different grade of blade.
For a diamond blade to work properly, the diamond type, quality
and grit size must be selected for the material to be cut. The metal
matrix must also be “matched” to the material. Blades for cutting
hard, dense (less abrasive) materials such as, hard brick, stone or
hard cured concrete require a softer metal matrix. The softer metal
matrix wears faster, replacing worn out diamonds fast enough for
blades to keep cutting.
Blades for cutting soft, abrasive materials (such as green concrete
or asphalt) must have a hard metal matrix to resist abrasion and
“hold” the diamonds longer.
Diamond blades with grades for specific applications are available
from your Parchem branch.

SAFETY
NEVER allow any person to operate 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.
WARNING! Serious injury or blade damage may result from
improper use of a diamond blade.
ALWAYS make sure the operator is stable and on level ground
before attempting to use the foot pedal. By using the foot pedal the
operator has to raise a foot off the ground when cutting and this is
not recommended as this will affect the balance of the operator.
ELECTRICAL HAZARDS !
THE RISK OF SERIOUS OR LETHAL INJURY FROM
ELECTRICAL SHOCK may arise from the combination of electricity
and moisture. ELECTRICAL HAZARDS may be high due to the
careless use of equipment and extension leads.
USE AN ELECTRICAL SUPPLY EQUIPPED WITH A RESIDUAL
CURRENT DEVICE (RCD) for protection against electrocution.
ARCD is an electronic protection device that is available for
connection between the power source and the equipment. It is
designed to monitor the balance of the current flow in the active
and neutral wires of the plugged-in equipment and immediately
trips before a fatal amount of power can pass through the operator.
The RCD can be permanently wired at the supply switchboard
or inserted as a removable plug-in device in the electric cable, in
which case it should be located as close to the supply as possible
with the RCD located before any extension leads
INSPECT electrical leads, plugs and sockets regularly for damage.
DO NOT operate the machine using coiled or tangled extension
leads. ENSURE that repairs to the electric motor and wiring are
carried out immediately by QUALIFIED personnel.
DO NOT hose or drain the water from the machine while the
electrical supply is connected.
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 power lead is unplugged before removing or
refitting the diamond blade or making adjustments to the vee belt
tension.
KEEP hands and feet clear of rotating and moving parts as they
will cause injury if contacted. 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.
ONLY use a diamond impregnated saw blade. Never use abrasive
or woodworking blades. ALWAYS support the material to be cut on
the table. Never hold the work to be cut by hand alone.
ENSURE that the ribbed mat is fixed to the table at all times as it
provides a non skid surface to support the work.
ENSURE that the rubber splash apron is fitted at all times as it
functions to keep water spray off the motor. DO NOT allow waste
water to accumulate under foot. ENSURE that the nut securing the
blade flange is locked tight (left-hand thread on shaft and nut).
BEFORE mounting the blade ensure that the correct blade flanges
are fitted to the machine and the blade and flange faces are clean,
flat, free from warping and grit. ENSURE that the mounting hole in
the blade matches the diameter of the machine spindle and that the
blade does not rattle or wobble.
CHECK that the blade is clear of the material to be cut before
starting the machine. DO NOT stand in line with the blade when
starting the machine. KEEP bystanders and animals clear of the
work area. ENSURE that the material to be cut will remain stable
and will not move or fall while cutting.
NOISE
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. Noise levels in excess of 85dB(A) may be produced by
diamond cutting blades.
PROTECTIVE CLOTHING
Always wear approved hearing protection, safety glasses, face &
head protection, and respirators.
Protective clothing & footwear may also be necessary.
OPERATION
To set up the legs, open them fully and make sure they are
stable and on level terrain. Using the lifting handles provided on
the machine, along with correct lifting techniques, two people of
appropriate strength can then position the unit onto the legs. Place
the rubber stoppers mounted on the underside of the tray into the
sockets provided on the legs.
When the town water supply is available the water supply can be
connected to the water connector. This will ensure an adequate
supply of clean water.
When the optional water pump is in use fill the tray with water to
a depth of approximately 50 mm. Keep the water supply clean by
draining and refilling the tray regularly.
Remove sediment when it covers the bottom of the tray by more
than 10 - 15 mm. Check that the table rollers are aligned on the
tray and that the table moves freely. Check the blade depth stop to
ensure that the table does not collide with the blade. The operator
should stand with feet apart facing the machine.
Ensure that the material to be cut is resting securely on the table
and is placed against the backstop.
Before starting the motor make sure either the town water supply
is connected or the tray is filled and the water pump is ready. Open
the water stop cock before commencing cutting.
When an extension lead is used, select the shortest length and
heaviest conductor size available to minimise voltage drop and
prevent motor “burn out”. Start the electric motor by turning the
switch mounted on the front of the motor to ON.
ALWAYS maintain good footing so that you do not slip and loose
control when starting or operating the machine.
Apply light steady pressure to feed the work past the blade.
Excessive force should not be used. The most efficient cutting
method is to use several shallow cuts (not one deep cut).
Check the water flow rate regularly to ensure that the town supply
has not been interrupted or the tray supply has not become choked
with sediment.
Wet cutting diamond blades must be kept cooled whilst cutting.
Water keeps the blade cool, removes cuttings and keeps dust
down.
Ensure that there is an adequate flow of water onto both sides of
the blade. If too little water is supplied to the cutting area steam
may be seen rising. A continuous flow of water is critical to ensure
that no blade damage occurs whilst cutting. A blade that is used for
even a brief time dry may be damaged or destroyed.
Locate the work so that when the cut is completed the cut surfaces
do not bend and foul the sides of the blade.

CARE AND MAINTENANCE
ENSURE that repairs to the motor and machine are carried out by
COMPETENT personnel.
Do not transport spare diamond blades without suitable protection
as they are easily damaged. Inspect the diamond blade for
chipped or missing segments. If damage is found, replace the
blade or return to the supplier for repair. Inspect the blade drive
belt for wear or cracking.
Check the blade spindle bearings and the motor for loose
mounting bolts or screws. Inspect and lubricate the two blade arm
bearings and two blade spindle bearings with grease regularly.
Inspect the water hose and its connections to ensure that they
do not leak and spray water onto the motor. Clean the table roller
grooves and the top of the guide rails.
Check the electric motor switch and the capacitor covers for
damage and “water tightness” each week. Apply grease to the
blade flange locking nut threads regularly.
CLEANING AND STORAGE
Drain the water from the tray and clean out the sediment daily after
use. Remove the table from the rails or secure it while the machine
is in transit. Before storing the machine, spray the blade flanges
and fasteners with a rust inhibitor.
