inspection. Never use the Certa Petrol Demolition Concrete Saw when it is not
completely assembled.
Cut-off discs
The protection hood must always be on! Change discs only with the engine off!
•There are two basic types of cut-off discs:
oFor metal (hot cutting)
oFor masonry (cold cutting)
WARNING!
Never use carbide tipped, circular saw blades or any kind of wood cutting blades. Never
cut any type of wood. Reactive forces can cause severe personal injury from blade
contact or thrown tips.
Note:
When using diamond cut-off discs, always make sure to observe the “direction of rotation”
markings. Diamond discs should only be used for cutting Masonry/brick/ concrete etc.
= Wearing Protective
Equipment

•Cut-off discs are intended only for radial
loading, i.e. for cutting. Do not grind with the
sides of the cutting disc! This will break the
disc! 10
Caution!
Never change direction (turning radius less than 5
meters (16 feet), exert lateral (sideways) pressure or
tip the Certa Petrol Demolition Concrete Saw during
cutting! 11
•Use a cutting disc only for cutting the
materials it is intended for. The proper type of
disc must be used, for either metals or
masonry.
•The arbour hole of the cutting disc must be an
exact fit with the arbour or shaft if the arbour
hole is larger, it must be fitted with an adapter
ring (available as an accessory).
•The cutting disc must be rated for freehand
cutting at up to 4370 rpm or 80 m/sec for 350
mm discs or up to 5100 rpm or 80 m/s for 300
mm discs. Use only cutting discs that comply
with EN 12413, EN 13236.
•The disc must be free of defects. Do not use
defective cutting discs. 12
Always tighten the cutting disc mounting bolt to a torque of 30 Nm. Otherwise, the cutting
disc can twist.
•Before starting the cutting disc, make sure you have a steady footing.
•Put the Certa Petrol Demolition Concrete Saw
into operation only as described in this user
guide.13 Always place your left foot in the rear
handle and grasp the other handle firmly (with
thumb and fingers). Other starling methods are
not allowed.
•When starting the Certa Petrol Demolition
Concrete Saw it must be well supported and
securely held.
•The cutting disc must not be touching anything.
•If the cutting disc is new, test it by running it at least 60 seconds at top speed, when
doing this, make sure that no persons or body parts are in the extended swing range of
the disc, in case it is defective and flies apart.
•When working with the Certa Petrol Demolition Concrete Saw always hold it with both
hands.
•Take the back handle with the right hand and the tubular handle with the left hand
Hold the handles tightly with your thumbs facing your fingers.

•Caution:When you release the throttle lever the disc will keep spinning for a short
period (free-wheeling effect).
•Continuously ensure that you have a safe footing.
•Hold the Certa Petrol Demolition Concrete Saw such that you will not
breathe in the exhaust gas. Do not work in closed rooms or deep holes or
ditches (danger of poisoning by fumes).
•Warning:Carbon monoxide produced during use can kill-do not use Certa Petrol
Demolition Concrete Sawter indoors-make sure there is proper ventilation when using
Certa Petrol Demolition Concrete Saw in trenches or other confined spaces.
•Switch off the Certa Petrol Demolition Concrete Saw immediately if you observe any
changes in its operating behaviour.
•Switch oil the engine before inspecting the v-
belt tension or tightening it, replacing the
cutting wheel or eliminating faults.14
•Turn off the engine immediately and check the
disc if you hear or feel any change in cutting
behaviour.
•Turn off the Certa Petrol Demolition Concrete
Saw when taking a break or stopping work.14 Place the unit in such a way that the disc
is not touching anything and cannot endanger anyone.
•Do not put the overheated Certa Petrol Demolition Concrete Saw in dry grass or on
any inflammable objects. The muffler is very hot (danger of fire).
•Important: After wet cutting, first turn off the water feed and then let the disc run at
least 30 seconds, to fling off the remaining water and prevent corrosion.
Kickback, lock-in and gyroscopic forces
•When working with the Certa Petrol Demolition
Concrete Saw there is a danger of kickback and
lock-in.
•Kickback occurs when the top of the cutting disc
is used for cutting.15
•This causes the Certa Petrol Demolition Concrete Saw to be thrown back toward the
user with great force and out of control. Risk of Injury!
To prevent kickback, observe the following:
•Never cut with the section of the cutting disc shown in Figure 15. Be especially careful
when reinserting the disc into cuts that have already been started!
•Lock-in occurs when the cut narrows (crack or workpiece under stress).
•This causes the Certa Petrol Demolition Concrete Saw to suddenly jump forward, out
of control and with great force. Risk of injury!
•Refuelling
•Changing cut-off discs
•Stopping work
•Transport
•Putting out of function
•Maintenance

To prevent lock-in, observe the following:
•When reinserting the disc into previous cuts,
have the Certa Petrol Demolition Concrete
Saw running at top speed. Always cut at top
speed.
•Always support the workpiece so that the cut
is under tension16 so that the cut does not
press together and jam the cutting disc as it
proceeds through the material.
•When starting a cut, apply the disc to the workpiece with care. Do not just shove it into
the material.
•Never cut more than one piece at a time! When cutting, make sure that no other
workpiece comes into contact.
•Gyroscopic forces come into play when handling a Certa Petrol Demolition Concrete
Saw with a rapidly rotating composite wheel.
•To prevent gyroscopic forces developing, note the following: Do not rotate the machine
rapidly about its longitudinal axis!
•Be warned” If gyroscopic forces are present, the saw will react in an uncontrolled
manner, and there is a danger that injuries may occur.
Working behaviour/Method of working
•Check the integrity of the composite wheel both before and after fitting it to the
machine.
•Before starting work, check the work area for any hazards (electrical wires, inflammable
substances) marks the work area (for example with warning signs or by cordoning off
the area).
•When working with the Certa Petrol Demolition Concrete Saw, hold it firmly by the
front and rear handles. Never leave the Certa Petrol Demolition Concrete Saw
unattended!
•Use the Certa Petrol Demolition Concrete Saw at high speed as far as possible (see
Specifications section).
•Only use the Certa Petrol Demolition Concrete Saw during good light and visibility
periods. Be aware of slippery or wet areas and of ice and snow. Risk of slipping!
•Never work on unstable surfaces Make sure
that there are no obstacles in the working
area, risk of stumbling. Always ensure that you
have a safe footing.
•Never cut above your shoulder height.17
•Never stand on a ladder to cut.17
•Never use the Certa Petrol Demolition
Concrete Saw while standing on scaffolding.

•Do not lean over too far when working. When
putting down and picking up the Certa Petrol
Demolition Concrete Saw, do not bend over from
the waist, but instead bend in the knees.
•Guide the Certa Petrol Demolition Concrete Saw
in such a way that no part of your body is within
the extended swing range of the disk.18
•Use cutting discs only for the materials for which they are designed!
•Use cutting discs only for the materials for which they are designed. Do not use the
Certa Petrol Demolition Concrete Saw to lift and shovel away pieces of material and
other objects. Important! Before cutting, remove all foreign objects, such as rocks,
gravel, nails etc. from the cutting area. Otherwise, such objects can be flung away by
the disc with great speed. Injury hazard!
•When cutting workpieces down to length, use firm support. If necessary, secure the
workpiece from slipping, but do not steady it with your foot or allow another person to
hold it.
•When cutting round items, always secure them against rotation.
•When using synthetic resin cutting discs, always observe the following:
Caution:
oSynthetic resin cutting discs can absorb moisture.
oThis moisture can cause the disc to become unbalanced at high speed. This
imbalance can cause the disc to break.
oDo not cool resin cutting discs with water or other fluids.
oDo not expose resin cutting discs to high humidity or rain!
Do not use resin cutting discs past their use-by date (expiration date)! The date (quarter and
year) is stamped on the disc's arbour ring.
Example: 04/2020. This cutting disc can be used through the end of the fourth quarter of
2020 if properly stored and correctly used.
Cutting metals
Important!
•Always wear approved respiratory protection!
•Materials that can release toxic substances may be cut only after notifying the proper
authorities and under their supervision or that of a person appointed by them.
Caution!
The rapid rotation of the cutting disc heats the metal
and melts it at the point of contact. Swing the guard
as far down as possible19 to direct the stream of sparks
forward, away from the operator (fire hazard).

•Determine the cut line, mark the cut and apply
the disc to the material at moderate speed, to cut
a guide groove before going to top speed and
applying more pressure to the Certa Petrol
Demolition Concrete Saw.
•Keep the disc straight and vertical. Do not tip it,
as this can break it.
•The best way to get a good, clean-cut is to pull or
move the Certa Petrol Demolition Concrete Saw back and forth. Do not simply press
the disc into the material.
•Thick round stock is best to cut in stages.20
•Thin tubing and pipes can be cut with a simple downward cut.
•Cut large-diameter pipes as for round stock. To prevent tipping and for better control,
do not let the disc sink too deeply into the material. Instead, always cut shallow
around the whole piece.
•Worn discs have a smaller diameter than new discs so that at the same engine speed
they have a lower effective circumferential speed and therefore do not cut as well.
•Cut I-beams and L-bars in steps; see Figure 21.
•Cut bands and plates like pipes: along the wide
side with a long cut.
•When cutting material under stress (supported
material or material in structures), always make
a notch in the thrust (pressure) side and then
cut from the tension side, so that the disc does
not lock-in. Secure cut-off material from falling!
CAUTION!
If there is a chance that the material is under stress, be prepared for it to kickback. Make sure
you can get out of the way if necessary.
Be particularly careful in scrap-metal yards, junkyards, at accident sites and with haphazard
piles of material. Precariously balanced pieces or pieces under stress can act in
unpredictable ways and may slide, jump out or burst. Secure cut-off material from falling!
Always exercise extreme caution and use only equipment that is in perfect working order.
Observe the accident-prevention rules and regulations of your employer and/or insurance
organisation.
Cutting masonry and concrete
IMPORTANT!
Always wear approved respiratory protection!
Asbestos and other materials that can release toxic substances may be cut only after
notifying the proper authorities and under their supervision or that of a person appointed by
them. While cutting pressurised and reinforced concrete piles, follow the instructions and
standards of the responsible authorities or the builder of the structural member.
Reinforcement rods must be cut in the prescribed sequence and by applicable safety
regulations.

Note:
Mortar, stone and concrete develop large quantities of dust during cutting. To increase the
lifetime of the editing disc (by cooling) to improve visibility and to avoid excessive dust
creation, it strongly recommends wet cutting instead of dry cutting.
In wet cutting, the disc is wetted at an equal rate on both sides by a trickle of water; offers
the right accessories for all wet cutting applications (see also “Special accessories”).
•Remove foreign objects such as sand, stones and
nails found within the working area.
•Caution: Watch out for electric wires and cables!
The rapid rotation of the cutting disc at the point of
contact throws fragments out of the cut groove at high
speed. For your safety, swing the protection hood down
as far as possible,23 so that material fragments are
thrown forward, away from the operator.
•Mark the cut and then make a groove about 5 mm (just under 1/5”) along the entire
length of the planned cut. This groove will then guide the Certa Petrol Demolition
Concrete Saw accurately during the actual cut-off.
•Perform the cut with a steady back-and-forth
motion.
•When cutting slabs to size, you need not cut
through the entire material thickness (creating
unnecessary dust). Instead, simply make a
shallow groove and then knock off the excess
material cleanly on a flat surface.25
CAREFUL!
When cutting into lengths, cutting through material, making cut-outs, etc., always make
sure to plan the direction and sequence of cuts in such a way that the disc does not get
jammed by the cut-off piece and that no persons can be injured by falling pieces.
First aid
For the event of a possible accident, please make sure that a first aid kit is always
immediately available close by. Immediately replace any items used from the first aid box.
When calling for help, give the following information:
•Place of the accident

following assembly steps:
Mounting the cutting disc
1. Cross sleeve
2. Allen key
3. Cutting disc
4. Large plate #1
5. Small plate
6. M10x20 Hexagon screw
7. Large plate #2
8. Belt protection cover
The inner hole of the cutting disc is selected to be installed in sequence as shown in the
second configuration image above:
•Large plate #1, cutting plate (the cutting direction is consistent with the arrow of
the wheel housing), Large plate #2 (with the small step facing outward), small
plate, then the M10x20 outer hexagonal screw.
The inner hole of the cutting disc is 25.4, which shall be installed in sequence as shown in
the first configuration image above:
•Large plate #2 (small step outward), cutting plate (the cutting direction is
consistent with the arrow of the grinding wheel cover), large plate #1, small plate,
then the M10x20 outer hexagonal screw shall be installed.

Disassembling and cutting disc
•First, insert the Allen key into the middle hole of the belt protection cover. The
cutting disc cannot be rotated.
•Use the cross sleeve M10x20 outer hexagon screws to loosen or tighten to complete
the disassembly of the cutting disc.

Caution:
•This tool uses petroleum products (petrol and oil).
•Be especially careful when handling petrol.
•Do not smoke. Do not allow petrol to come near flames, sparks or tire (explosion
hazard).
Fuel mixture:
•This tool is powered by a high-performance air-
cooled two-stroke engine. It runs on a mixture of
petrol and two-stroke engine oil.
•The engine is designed for unleaded regular
petrol with a min. octane value of 89. In case no
such fuel is available, you can use fuel with a
higher-octane value. This will not affect the
engine.
•To obtain an optimum engine output and to
protect your health and the environment use
unleaded fuel only.
•To lubricate the engine, use synthetic oil for two-stroke air-cooled engines, this must
be added to the fuel.
The correct mixture ratio:
•40:1 When using synthetic two-stroke engine oil, i.e. 40 parts petrol to 1-part oil.
Note:For preparing the fuel-oil mixture, first mix the entire oil quantity with half of the fuel
required, then add the remaining fuel.
Thoroughly blend the mixture before filling it into the tank.
Caution: Open the tank cap carefully, as pressure might have built up inside!
It is not wise to add more engine oil than specified to ensure safe operation. This will only
result in higher production of combustion residues which will pollute the environment and
clog the exhaust channel in the cylinder as well as the muffler. Also, fuel consumption will
rise and performance will decrease.
Fuel Storage
Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially
at high temperatures Aged fuel and fuel mixtures can cause starting problems and damage
the engine. Purchase only that amount of fuel, which will be consumed over the next few
months. At high temperatures, once the fuel has been mixed it should be used up in 6-8
weeks.
Store fuel only in proper containers, in dry, cools, secure locations!
