Using The Machine - EMAK MISTRAL 72/13 H Manual De Uso

- Petrol and petrol fumes can cause serious injury when
inhaled or allowed to come in contact with the skin. For
this reason observe caution when handling fuel and
make sure there is adequate ventilation.
- Pay attention to the risk of poisoning from carbon
monoxide, an odourless, toxic and lethal gas.
- Handle fuel outdoors where there are no sparks or flames.
- Select bare ground, stop the engine, and allow to cool
before refuelling.
- Never use stale or contaminated petrol or an oil/petrol
mixture. Avoid getting dirt or water in the fuel tank.
- Avoid dripping petrol onto plastic parts to prevent them
being damaged. In the event of accidental spillages, rinse
immediately with water. The warranty does not cover for
damage to plastic parts of the bodywork or the engine
caused by petrol.
- Loosen fuel cap slowly to release pressure and to keep fuel
from escaping around the cap.
- Clean surface around fuel cap to prevent contamination.
- Prior to replacing the fuel cap, clean and inspect the gasket.
- Tighten fuel cap securely after refuelling. Unit vibration can
cause an improperly tightened fuel cap to loosen or come
off and spill quantities of fuel.
- Wipe spilled fuel from the unit and allow remaining fuel to
evaporate. Move 3 m away from refuelling site before
starting engine.
- Never attempt to burn off spilled fuel under any
circumstances.
- Never place the machine in an area with combustible
materials such as dry leaves, straw, paper, etc.
- Never take the cap off the tank when the engine is running.
- Take care not to get fuel on your clothing. If you have
spilled fuel on yourself or your clothes, change your clothes.
Wash any part of your body that has come in contact with
fuel. Use soap and water.
- Do not expose the fuel tank to direct sunlight.
- Store and transport fuel in a clean container approved for
petrol.
- Store fuel in a cool, dry, well-ventilated place.
- Store the unit and fuel in an area where fuel vapours cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.
- Keep fuel out of reach of children.
- Never use fuel for cleaning operations.
WARNING
- Refuelling should be carried out in an open and well-
ventilated area with the engine off. Always remember
that petrol fumes are inflammable. DO NOT USE A
NAKED FLAME TO LOOK INSIDE THE TANK AND DO NOT
SMOKE WHEN REFUELLING.
- Check for fuel leaks, if any are found, correct before use.
Contact an authorised service workshop if necessary.
After having removed the fuel cap (A, Fig.9) refuel using a
funnel, but do not completely fill the tank. The tank's capacity
is about 6 litres.
Tyre pressure
Having the right tyre pressure is the main condition for
ensuring that the cutting deck is perfectly horizontal and
mows evenly. Unscrew the valve caps and connect a
compressed air line with a gauge to the valves.
The pressures must be:
FRONT 1.5 bar
REAR 1.0 bar
Fitting the grass-catcher or stone-guard
WARNING: Never use the machine without having
fitted the grass-catcher or stone-guard.
Hook on the grass-catcher by inserting the top part of the
frame (A, Fig.13) in the two slots on the supports (B), making
sure the two arrows line up. If you decide to mow without the
grass-catcher, you can mount an optional stone-guard kit (C).
It attaches in the same way as the grass catcher and must also
be fixed to the rear plate using the supplied pins (D) and
cotter pins (E), as shown in the figure.
Checking machine safety and efficiency
1. Check that the security devices operate as indicated in the
summary on page 29.
2. Check that the brake is in perfect working order.
3. Do not start mowing if the blade vibrates or if you are
unsure whether it is sharp enough. Always remember that:
- A badly sharpened blade pulls at the grass and causes the
lawn to turn yellow.
- A loose blade causes unwanted vibrations and can be
dangerous.
WARNING: Do not use the machine if you are unsure
whether it is working safely or efficiently. If in doubt,
contact your Dealer immediately to make the
necessary checks and repairs.

6.2 Using the Machine

Starting
WARNING: The engine must be started in an open or
well-ventilated area. ALWAYS REMEMBER THAT
EXHAUST GASES ARE TOXIC.
Before starting the engine:
- open the fuel stop-cock (A, Fig.11), which can be reached
from the left rear wheel compartment;
- do not touch the speed adjustment pedals;
disengage the blade;
- apply the parking brake, especially if on sloping ground.
Then perform the following operations:
- set the accelerator lever to the "STARTER" position in the
case of cold starting, or between "SLOW" and "FAST" if the
engine is already warm;
- insert the ignition key and turn to "ACC" (1) to activate the
electrical circuit, then turn to "START" (ON) to start the
engine. Release the key once the engine has started.
When the engine has started, move the accelerator to "SLOW".
CAUTION
- The choke must be closed as soon as the engine is running
smoothly. Using it when the engine is already warm can
foul the spark plug and cause the engine to run erratically.
- In the event of engine starting problems, do not insist as
you can risk running the battery flat and flooding the
engine. Turn the key to OFF, wait for a few seconds and then
repeat the operation. If the malfunction persists, refer to the
TROUBLESHOOTING table on page 36 of this manual.
- Always bear in mind that the safety devices prevent the
engine from starting if safety requirements have not been
met (see page 29). In these cases, once the situation has
been corrected, the key must first be turned back to OFF
