Blade Inspection - IBEA 530 Série Notice D'emploi Et D'entretien

5. Tighten the screw on the cable plate, whilst the throttle ca-
ble is in this position.
Servicing the air filter
Clean the air filter every 25 hours. Replace it every season. (See
engine manual for further information).

Blade inspection

The frequency of blade inspection depends on the working
conditions.
1. Make sure that the engine is not running and the high wire
is disconnected from the spark plug.
2. Drain petrol from the fuel tank.
3. Tip mower on its right side. Avoid rotating the blade when
the mower is tipped because starting problems may result.
4. Carefully examine the blade:
a) If the cutting edge has become rounded it must be
sharpened.
b) Check where the flat and curved parts meet and, if there
are any cracks or signs of wear replace the blade immedi-
ately.
ATTENTION: A worn or cracked blade can easily break dur-
ing use or pieces may break off, resulting in serious injury to
yourself or a bystander.
Sharpening or replacing the cutter blade
1. Turn the engine off and disconnect the high tension wire
from the spark plug.
2. Drain fuel from the fuel tank.
3. Tip mower on its right side. Avoid rotating the blade when
the mower is tipped up because starting problems may re-
sult.
4. Hold the blade firmly with a gloved hand and, using a span-
ner, unscrew the bolt and washer (fig. 10).
5. Remove the blade in order to sharpen or replace it.
6. Using a flat file, sharpen the top side of blade, maintaining
the original cutting angle. The blade will remain balanced if
the same amount of material is removed from both cutting
edges.
7. Check the balance of the blade by using a blade balancer.
An unbalanced blade will lean on its heavier side. If the
blade is not balanced file more metal off the cutting edge of
the heavy side and check the balance again.
8. Install a sharp, balanced blade, following the above proce-
dure in reverse sequence (see points 4 and 5).
9. Tighten the blade bolt to 5,5 Kgm.
NOTE: A blade balancer may be purchased at any good
hardware shop.
ATTENTION: In order to obtain best possible cutting results,
we recommend that you replace the blade annually in addi-
tion to sharpening it whenever necessary.
Cleaning the mower deck
To assure optimum performance, keep the underside of the
mower deck and the grass discharge area clean.
1 Check that the engine has stopped and the high tension
wire is disconnected from the spark plug.
2. Drain the fuel tank.
3. Tip the mower on its right side. Avoid rotating the blade
when the mower is tipped up as starting problems may re-
sult.
4. Remove dirt and grass clippings from the underside of the
deck. Scrape away any remaining dirt with a handtool, be-
ing careful not to injure yourself with the blade or sharp
edges.
5. When completed, return the mower to its upright position.
Traction cable adjustment
After the first hours of use it is possible that the traction han-
dle cable loosens and it becomes difficult to use.
If this happens, adjust the cable regulator (fig. 11).
The adjustment is correct when the traction goes into action
with adistance of 30 mm between the traction handle and the
handlebar (fig. 12).
To adjust the traction cable, turn the register.
Preparing mower for storage (more than a month).
1. Drain fuel from the tank.
2. Start engine and let it run until it stops, due to lack of fuel.
ATTENTION: All petrol must be expended to prevent gum-
like varnish deposits from forming in the carburetor, fuel
line and fuel tank. Such deposits, if allowed to form, will
cause starting problems and poor engine performance.
3. Remove the high tension wire from the spark plug and
clean the surrounding area so that dirt cannot penetrate
the cylinder when the spark plug is removed. Remove the
spark plug and pour a spoonful of 2-cycle oil into the cylin-
der chamber. Pull the recoil starter handle slowly to distrib-
ute oil on the inside of the cylinder. Then install the spark
plug and tighten, using a spanner. Do not install the high
tension wire on the spark plug.
4. Clean the cylinder head cooler fins, external engine parts
and mower deck.
5. Check and tighten all screws, bolts and nuts. If any parts
are damaged, repair or replace them.
6. Inspect the grassbag. Replace it if damaged or worn.
7. Check the condition of the blade and blade bolt; refer to
"Blade inspection".
8. Clean the air filter (see engine manufacturer's manual).
9. Touch-up all chipped paint surfaces.
10. Store the mower in a clean, dry place. The handles may be
folded to save space. Cover the mower to protect it and
keep it clean, ready for next season.
NOTE: Before using the mower again, check that the handles
are well installed and all knobs are tightened.
