9• Maintenance - Etesia MBHE2 Original User Manual

Before carrying out any maintenance, turn off the engine and
remove the ignition key.
9•1 CLEANING
The best maintenance is above all the regular cleaning of your mower
each time you use it.
• It is highly unadvisable to use a high pressure cleaner.
In any case, be sure not to spray water on to the parts of the engine
parts. Do not direct water onto the bearings (blade or wheel bearings)
or the hydraulic components.
• It is recommended that the engine and all the transmission compo-
nents be operated after cleaning to ensure the evacuation of any water
that might have leaked into the moving parts.
9•2 CUTTER HOUSING
9•2•1 CLEANING THE CUTTER HOUSING
• After using the mower, always clean the cutter housing, particularly
the inside face.
• Cleaning the cutter housing using the pipe coupling.
• On the left-hand side of the cutter housing is a coupling allowing
connection of a garden hose (see a picture 2).
- Connect the hose to the cutter housing.
- Remove the bottom of the grass box (see picture 7a) (except MKM).
- Switch on the water tap.
- Sit on the mower, and start up the engine and cutter.
- After approximately 3 minutes the blade is clean.
- Switch off the cutter and then the engine.
- Switch off the water and disconnect the hose.
- Switch the cutter on again for a few minutes in order to expel the
water.
9•2•2 CLEANING THE CUTTER FOLLOWING
REMOVAL (SEE § 8•4)
If the mower has been used under particularly tough conditions (very
wet grass, mowing in a very low position), it may be necessary to
remove the cutting plate and clean it with a scraper. Take advantage of
the opportunity to check the condition of the blade and the coupling,
and of replacing them if necessary. A properly maintained cutting
system will improve cutting quality.
9•2•3 CLEANING THE GRASS BOX (EXCEPT
MKM)
• Like the cutter housing, the grass box should always be cleaned after
a garden hose.
WARNING !
Proper maintenance of the cutter housing and grass box will
improve grass cutting and collection and prolong the life of
the mower.
9•2•4 MAINTENANCE OF THE CUTTER
WARNING !
Before carrying out any work on the cutting mechanism,
always switch off the engine and remove the ignition key.
Protective gloves should also always be worn.
9• MAINTENANCE
• CONDITION OF THE CUTTER (BLADE)
• Before using the mower, always check the blade for signs of damage
or wear:
1: Normal 2: Twisted 3: Worn 4: Split (see picture 34)
• If the blade is blunt or twisted, the mower will not cut or collect
correctly.
- Damaged blades can be highly dangerous if a section of the blade
becomes detached and is ejected from the cutter housing.
• Change absolutely the blade after any shock.
• Some microcracks provoked by a shock can lead to the rupture of the
blade if it's not replaced.
• Change worn or damaged blades immediately (see section below).
- Blades which are blunt but do not present other signs of damage
may be re-sharpened.
- Do not resharpen the blade beyond the limit marked on the blade
edge.
- After sharpening, the blade should be re-balanced to prevent vibration.
- The blade coupling should also be checked to ensure that it is in
good working order.
• In the case of serious damage to the cutter housing, the entire cutting
mechanism should be examined by your approved dealer/repairer.
