INTRODUCTION
Thank you for your selection of equipment supplied by Parchem.
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 themselves
or others. We recommend that all operators and service personnel
read, understand and follow this manual.
APPLICATIONS
Ceramic tiles
Slate
Concrete blocks and pavers
Marble
Geological core samples

Clay bricks and pavers
Sandstone
Fibreglass pipe
Granite
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.
