Climber 9.22 / Translation of the original instructions
Vibrations during operation
– Blades unbalanced – Balance blades or replace if damaged
– Fastenings are loose – Check and fasten the blade fixing screws
as well as the fixing screws of the engine
and chassis.
Incorrect P.T.O. engagement
– Check the battery voltage, it must be at least 12,5 volts
– Check the levelness of the blade brake and the
electromagnetic clutch, 0,3 mm
ELECTRICAL SYSTEM
The electrical system is protected by a fuse which cuts out the entire electrical system if blown. After finding and repairing the
fault, replace the fuse with another of the same rating. Never replace the fuse with one of a different rating. The electrical
system fuses are underneath the tank (fig. 19). If the problems persist after all the procedures described above have been
carried out, contact the Authorised After-Sales Service Centre. Never attempt to make difficult repairs unless you have the
necessary equipment and technical expertise.
ELECTRONIC CONTROL UNIT
Inside the steering column there is an electronic control unit (fig. 19) that controls all the electric functions of the machine (e.g.
PTO, safety micro-switches).
IMPORTANT!
– Take care not to reverse the battery polarity.
– Never operate the mower without the battery, since it is equipped with a charge regulator.
– Take care not to cause short-circuits.
THE MACHINE DOES NOT REMAIN IN NEUTRAL
Adjust the zero turn device by tightening or loosening it (fig. 17). to adjust the forward and reverse travel speeds, use the screws
(fig. 18).
END OF WORK
After mowing, disengage the blades and drive back to base with the cutter deck in the highest position. To stop, move the
forward lever to the STOP position (fig. 1B, no. 2), set the throttle lever at the minimum r.p.m., switch off the engine by turning
the key on the STOP position (fig. 1, no.7) and lower the deck to the lowest position. Lock the park brake (fig. 23, no. 2).
CLEANING
Clean the outside of the mower after each use.
STORAGE AND PROLONGED PERIODS OF DISUSE
Store the brush cutter in a dry place, away from atmospheric agents, and preferably cover with a sheet. If the mower is not
going to be used for a long period (over 1 month), disconnect the red battery cable (fig. 23) and follow the instructions given in
the engine manual. Also lubricate all of the articulated joints. Regularly check that the battery voltage does not drop below 12
volts. If it does, recharge the battery.
If the machine is to be out of use for more than 30 days, drain the fuel from the engine to
prevent sticky deposits from forming in the fuel intake system or in vital parts of carburettor. To avoid this procedure, it is
possible to save fuel in storage up to 12 months by using an appropriate fuel stabilizer. Add such additive to the fuel in the tank
or in the fuel container. Run the engine for a while to let the stabilizer get into the fuel system.
Caution: if the engine is fed with
petrol containing alcohol, drain the fuel tank and run the engine until there is no fuel left.
TRANSPORTING THE MACHINE
If the machine has to be transported on a lorry or a trailer, fasten it to the vehicle using suitable ropes or cables.
