5. Remove the blade in order to sharpen or replace it.
6. Using a fl at fi le, 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 cut-
ting edges.
7. Check the balance of the blade by using a blade balancer.
An unbalanced blade will lean on its heavier side. If the bla-
de is not balanced fi le more metal off the cutting edge of
the heavy side and check the balance again.
8. Install a sharp, balanced blade, being careful to reassemble
all component in the correct order (fi g. 9).
9. Tighten the blade bolt to 5,5 Kgm.
NOTE: A blade balancer may be purchased at any good hard-
ware 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,
being careful not to injure yourself with the blade or sharp
edges.
5. When completed, return the mower to its upright posi-
tion.
Traction cable adjustment
After the fi rst hours of use it is possible that the traction hand-
le cable loosens and it becomes diffi cult to use.
If this happens, adjust the cable regulator as follows.
Loosen nuts on cable register (fi g. 10). It is now possible to
adjust traction cable play.
The traction must engage when there is a distance of 30 mm.
between handle and traction handle.
Lubrication (fi g. 11)
After every 25 operating hours, front and rear wheels must be
lubricated.
1. Wipe grease fi ttings with clean rags.
2. Install grease gun onto fi ttings and gently apply 2 or 3
pumps of Lithium N. 2.
Excess pressure may damage seals.
3. In order to lubricate wheel bearings, remove fi xing screws
and apply 2 or 3 pumps of Lithium N. 2 using greaser sup-
plied.
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 distri-
bute 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 fi ns, external engine parts
and mower deck.
5. Check and tighten all screws, bolts and nuts. If any parts
are damaged, repair or replace them.
Inspect the grassbag. Replace it if it is damaged or worn.
6. Check the condition of the blade and blade bolt; refer to
“Blade inspection”.
7. Clean the air fi lter (see engine manufacturer’s manual).
8. Touch-up all chipped paint surfaces.
9. Store the mower in a clean, dry place.
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.
