if necessary, lubricate the parts and components according to lubrication instructions
(chapter 7).
Parts, which may cause risk to operator’s health and safety are as follows: damaged disks,
tarpaulin covers, worn or damaged hydraulic hoses, PTO shaft guides, worn knives and knife
holders.
WARNING!
When performing maintenance or adjustment works underneath the mower,
use adequate locks for lifted parts of the machine preventing their falling and
risk of crushing.
6.9.3.
After-season maintenance and storing of machine
Upon completion of operation the following shall be performed:
lower the mower’s cutterbar onto the ground,
take the PTO shaft extension out of the tractor rpm or dismount the complete PTO shaft and
install it into corresponding holder at the 3-point linkage frame,
detach hydraulic and electrical hoses out of the tractor and hang them onto corresponding
holders on the 3-point linkage frame,
detach the mower from the tractor (reverse procedure as in case of attaching the mower to
the tractor
item 5.1), and then drive the tractor away.
Detached mower should be stored in standstill position, so it is supported onto supporting leg
and the cutterbar (
Fig. 27
). It is recommended to store the set on paved ground, preferably in roofed
places, inaccessible to unauthorized personnel or animals.
After storing for adequate period prior to the machine operation, its technical condition should
be examined and special attention should be paid to the hydraulics and the drive. Paintwork should
be complemented, hydraulic hoses checked and lubricated.
Additionally:
touch up any chips in the paint,
check the oil level in the angle drives and the cutterbar (Section 7). If leaks are discovered they
should be repaired immediately and lost oil replaced. If water in oil is discovered immediately
change the oil as it could cause corrosion of internal mechanisms such as gear wheels, bearings,
or shafts, and in effect be the cause of breakdowns,
periodically inspect the mower and lubricate moving parts in order to protect them from
corrosion which effects proper operation of the mower,
check hydraulic hoses regularly. Replace any damaged or old hoses. The period of hydraulic
hose utilization should not exceed 5 years from the date of their manufacture printed on
the hose.
After storage period, before the machine is used:
check the mower's technical condition, and the transmission in particular,
supplement the paint where missing,
make sure that all nuts and screws are tightened properly,
make sure that all guards are in place,
protect all moving parts with grease in order to prevent their baking and creating any sources of
corrosion, which significantly influences mower's proper operation,
check oil level in axis gears and cutterbar. If leaks are found remove them immediately and
refill the oil. If water in oil is found, immediately change the oil as it could cause corrosion of
internal mechanisms such as gear wheels, bearings, or shafts, and cause breakdowns.
