GENERAL
With the QFS-1200 a oor saw has been developed convincing by its compact size and low
weight. The working feed is effected by an electronically adjustable working feed drive. Blade
admission left and right side. Blade lowering by crank mechanism. The machine has been
specially designed to cut oor joints or oor separating cuts on civil or building engineering. To
execute the cuts you are using a corresponding diamond saw blade up to 1200mm diameter.
Danger
When cutting check that neither your hands nor your foots reach the
cutting area, note the you can seriously be injured when getting in
contact with the rotating saw blade. If you are not 100% familiar with the
use of the joint tailor Diaquip QFS-1200, we carefully recommend you
unconditional, to read this instruction manual and let you be instructed
be a technical staff. Use the machine correctly and only according to it
purpose.

1. PUTTING INTO SERVICE
1.1) Installation of the diamond saw blade
IMPORTANT: Switch motor off, remove power connection!
The protective hood 12 must be removed and the engine must be put with the pressure switch
05 in its highest position. Important: The fastening is with a left-hand thread on the right side.
A normal right-hand thread is on the left. The two ange parts have to be checked in respect of
cleanness, if necessary they have to be cleaned. When xing the diamond blade the rotating
direction shown by an arrow has to be observed. The fasting screw has to be tightened
normally with the fork wrench. An excessive tightening is senseless and leads to increased
ware. Now the cover hood 12 mast be mounted and xed again. The enclosed fork key SW22
matches for the corresponding screws.
Danger
Check that the cover hood is rmly mounted and that it the saw not toots
touch the cover hood.
At not right assembly of the diamond saw blade very danger!
You start the engine rst after all assembly work is completed completely
and the protective hood still is placed correctly!

1.2) Switching On / Off of the electrical main motor
The blade drive is effected by a 400 Volt three phase electric engine with 15kW power.
To start the engine, use the main switch installed on the engine. When starting the engine
check that neither your hands nor your foots reach the cutting area, note the you can
seriously be injured when getting in contact with the rotating saw blade.
To start turn the main switch 08 up to the position “star” and you stay in this position until the
diamond saw has reached its full revolutions (approx. 10-15 seconds). Then turn the switch
up to the position “triangle” . According to the direction of rotation of the diamond saw (rotating
direction shown by an arrow on the cover hood), you have to turn the main switch in to the
opposite direction.
Danger
It‘s important, that the machine is started in this order since otherwise
the net is overloaded.
If the engine is operated in the permanent operation into switch position
“star”, the motor is missing performance and it will take damage. The
engine works only in the position “triangle” in the permanent operation.
When turning the engine off you turn the main switch slowly backwards in the 2 steps to the
‘0-position‘. The Emergency-Button 07 on the top of the switch is always at your disposal. The
Emergency-Button 07 is pressed by pushing.
It is pointed out, to particularly, that the rearrangement to another tension or current intensity
only may be carried out by an expert.
The appropriate prescriptions of the VDE/SEV and the electricity works have to be observed at
connection of the engine. The connection network has to be checked. To protect the engine and
persons from damage, whether the being device is grounded net-sided unobjectionable has to
be checked.

1.3) Waters supply
Before cutting it has to be checked, that the saw blade is provided with sufciently cooling
water. The cooling water is guided through the cutting shaft and the ange. There are two type
of anges. There is a ange with a sealing joint. This ange is always to be used on the side
where the saw blade is not installed. The other ange 12 with water channels, has to be used
always with the saw blade.
Danger
Please note that too little cooling water or only single-sided water supply
has an important inuence of the life time and cutting characteristics of
the diamond saw blade!

2. CUTTING OPERATION
2.2) Working with the electrical working forward feed
As a rule, moving the machine to the cutting position shall be done by pushing the machine,
without the electrical working feed. The working feed is thought only for cutting.
A DC-Motor, 24 volts and 100 watts, drives the machine over two rubbing wheels for the rear
axle about a gear train. The forward working feed speed is adjustable electronically by a
potential converter 01. The potential converter permits to adjust the working feed speeds step
less between 0 and 12 m per minute.
The switching On / Off of the pushing forward working feed is carried out via the feed lever 02.
2.2.1) Depth adjusting
Adjusting the desired cutting depth is carried out with the threaded spindle. To prevent a altering
the easy common spindle stand-alonely becomes-show the pin 04 occurred at the hand crank.
A adjustable depth display on the left side on the machine shows the respective cutting depth.
According to the saw blade diameter lower the saw by using the hand crank 05 so that the saw
blade touching the ground. Now putting the cutting the indicator on the scale on zero.

Electric
Switch
Speed
The desired cutting depth is adjusted by a motorized threaded spindle unit. In order to rise or
lower the saw blade you use the electric switch on the left side of the machine panel. Turning
the switch form his zero position in two steps to the left side and hold
the switch in this position, the saw blade is going up; out of the cut. Turning the switch from
zero position to the right, the saw blade is going down, in to the cut. The speed of the motorized
depth adjusting unit can bee regulated be the potentiometer 01.
If the cutting depth is achieved, turn the speed regulated by potentiometer 01 to stop and then
turn the switch back to the zero position. Please note the potentiometer 01 is now active for the
cutting speed of the machine. (see also point 2.3.)
A adjustable depth display on the left side on the machine shows the respective cutting depth.
According to the saw blade diameter lower the saw blade by the motorized depth adjusting unit
so that the saw blade touching the ground. Now putting the cutting the indicator on the scale on
zero.

2. CUTTING OPERATION
2.3) Cutting operation
Aligning the machine according the cutting line. Lowering the direction indicators 11. Check that
nobody is near by the saw blade. Start the main engine according instruction under point 1.2 of
this manual. Putting on feed levers 02 and turning pushing forward knob 01 on 0 position and
then opening water supply. Adjust cutting depth indicate to zero according point 2.2.1.
With the lowering valve 04 you adjust to the desired cutting depth. Now you turn the pushing
forward knob (potentiometer) 01 an till the working feed speed has reached it maximum, so the
main motor dos not lose revolutions and that saw blade stays down in the cutting depth. Make
sure that the direction indicator 11 follows the predened cutting line.
Its recommends to start with the rst cut as a guide cut of only 5 to 6 cm depth. After this you
can easily work with cutting slices of 10 to 12cm depth an till you reach the full cutting depth.
Always drive at multiple slices in the same direction. Don’t pull the machine back with an the
saw blade still cutting since it is so possible that the diamond sheet of high stroke can get.
