10• MAINTENANCE
• Micro-cracks caused by an impact can lead to the breakage of the
blade at a later stage if it is not replaced.
• A blunt blade showing no other signs of damage can be sharpened
again. The sharpening limit marked on the end of the blade must not
be exceeded.
• After sharpening, the blade must be rebalanced to avoid vibrations.
• Also check that:
- the cutting unit coupling and body are in perfect condition.
- that the safety washer and cutting unit are in perfect condition.
• If signicant damage is observed on the cutter housing, a more detailed
examination of the complete system by your dealer will be necessary.
10•6 CLEANING
• It is not recommended to use high pressure washers. However, if you
use one, ensure that you do not spray water on engine parts such as
the carburettor, air lter, ignition, exhaust pipe, battery and electrical
parts. Do not direct the jet at the roller bearings (blade bearings or
wheel roller bearings) and hydraulic parts.
• It is recommend that you run the engine and all the transmission parts
after cleaning, in order to eliminate any remaining water.
CLEANING THE CUTTER UNIT
• After each use, clean the cutter housing carefully, in particular the
inside the ejection channel.
• Cleaning of the cutting unit using the hosepipe connections. The
cutter housing is equipped on the left and right-hand sides with ½
couplings allowing you to connect two hosepipe ttings (picture 35).
• To clean the housing, proceed as follows:
- Connect the hosepipe to the cutter housing. This can also be done
using a Y-branch so that the two sides are connected at the same
time.
- Turn the tap on.
- Sit on the seat, start the engine and activate the cutting unit.
- After about 3 minutes, the cutting unit will be clean.
• Cleaning the cutting unit ejection channel:
- Clear access to the ejection channel by putting the collecting bin
in the maximum top emptying position. Use the locking system to
lock it in this position (picture 32).
- Use a jet of water to clean out the ejection channel.
• After cleaning, put back the grass collection system, sit on the seat
and start the cutter unit again, for a few minutes.

TIGHTEN THE BLADE
TRANS-
MISSION TOOTHED BELT
The position of the blades as 90° from one another (picture 19) is
assured by a toothed belt.
A new toothed belt needs to be tightened up after 10 hours of operation
or at least 3 months after assembly if the mower has not been used.
The condition and tension of the belt must then be checked every 100
or 125 hours. Contact your dealer to re-tension the toothed belt.
10•8 MAINTENANCE OF THE MECHANI-
CAL TRANSMISSION (BPHP2 - BPHPX2)
The mechanical transmission fixed to the motor must be drained after
20 hours and then every 250 hours.
• Place the machine on a at surface, stop the motor, remove the ignition
key, apply the hand brake, wear gloves.
• Tip over the motor hood (see paragraph 9•1 page 23), then remove
the side housings of the motor.
• Place a sufficiently large container under the drain hole (a picture
36).
• Loosen the screw and let the oil drain into the container.
• Clean and then re-tighten the screw.
• Clean the plug (b picture 36) and ensure that no dirt gets into the tank
before tightening the plug.
• Slowly add 0.5 l of new oil. Etesia recommends SHELL OMALA
S4GX220 ref. 29590 (can of 1l).
Do not fill the tank. It does not indicate the transmission oil
level.
The recommended oil level corresponds to 0.5 l of new oil after
complete draining of the transmission. This level is flush with the
opening used to attach the pipe (c picture 36).
