MAINTENANCE
General Maintenance
All cleaning, lubrication, and maintenance operations must be carried out with the machine disconnected from
the tractor. In an emergency with the machine still connected to the tractor, turn engine off, apply parking
brake, disengage the power takeoff, remove ignition key and wait for all motion to come to a complete stop.
Regular maintenance and proper operation are the basic essentials for a long-term efficiency and safe
operation of the machine.
All maintenance should be carried out in an area having the proper equipment readily available and in good
condition. This area needs to be always clean and dry and must have enough surrounding space to facilitate
operations. Any work must be carried out by a trained person. Contact the dealer nearest you. Respect the
warnings and procedures for maintenance and technical assistance given in this manual.
Do not use pertrol, solvents or other flammable liquids as detergents. Use commercial non-flammable and non
toxic solvents, authorized by competent bodies.
Do not use compressed air or water at high pressure to clean the machine. If this is unavailable, then wear
goggles with side protection and limit the pressure as much as possible. When the work is finished, and with
the machine disconnected from the tractor, inspect the check the machine completely.
Never attempt to lubricate, adjust, or remove material from the Implement while it is in
motion or while tractor engine is running.
(SG-20)
Relieve hydraulic pressure prior to doing any maintenance or repair work
on the Implement. Place the Implement on the ground or securely
blocked up, disengage the PTO, and turn off the tractor engine. Push
and pull the Remote Cylinder lever in and out several times prior to
starting any maintenance or repair work.

Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners, worn
or broken parts, and leaky or loose fittings. Make sure all pins have
cotter pins and washers. Serious injury may occur from not maintaining
this machine in good working order.
