MACHINE MAINTENANCE
7.1
SUMMARY OF CHECKS AND MAINTENANCE
After season - before machine storage
Before season
Every 100 hours
Every 50 hours
Every 25 hours
Monthly
Regularly after each use
After fi rst 5 hours
After fi rst 2 hours
Before each use
Oil level check (gearbox, engine)
Engine oil changing
Fuel fi lter replacement
Accumulator maintenance (check of electrolyte level, cleaning)
Adjustment and check of belts
Check of brake control
Check of tyre pressures
Check of connection of cables (loosened quick-clamping parts)
Mowing machine cleaning
Check of bolted joints
Check of function of safety switches and elements
Check and adjustment of engine running, gearbox, electromagnetic clutch
Check and maintenance of air fi lter, sparking plugs, contingently the
replacement
Check of mowing mechanism condition (backlash, alignment of shafts,
check and sharpening of knives)
Explanatory notes to table:
1. Change the oil more frequently if the mowing machine is loaded more or if it works at outdoor temperatures about 35°C or higher.
2. Carry out the checking more frequently if the machine works in a dusty environment.
3. Carry out the checking more frequently if the machine works in a sandy environment.
4. Carry out the checking more frequently if a new belt is put on.
7.2
TYRE PRESSURE CHECK
Maintain the specifi ed pressures in the tyres and check them regularly. Different values of pressure can make the travel more
diffi cult and can contingently lead to the loss of control over the machine. Adherence to the prescribed pressure is also important
for the evenness of mowing.
•
Pressure in front tyres 80 - 140 kPa
•
Pressure in rear tyres 80 - 140 kPa

MAINTENANCE AFTER WORK
After fi nishing the mowing lift the mowing mechanism to the highest position and switch off the drive of knives. Switch off the
ignition, step on the brake pedal and secure the machine position by the parking brake.
7.3.1 CLEANING
After fi nishing the mowing remove every time all the impurities and remnants of grass from the machine surface as well as from
the mowing mechanism frame.
Before starting the cleaning, washing or machine repair, remove the keys from the ignition switch. Always work in solid
shoes, gloves and clothes designed for work. Avoid spilling the fuel, oil or other harmful substances.
7.3.2 WASHING
Avoid washing with water in vicinity of the electrical equipment on the control panel, accumulator, etc. Do not use high-pressure
devices.
Carry out the washing in the following way:
•
Wash the mowing machine on an even surface.
•
Clean the machine plastic parts using a sponge, water and soap.
•
Dismantle the pin 2 and pin 3 (see the fi gure in the chapter 7.13).
•
Lift the mowing mechanism, holding it for its frame, into the vertical position. Use a scraper and jet of water to remove the
remnants of grass from the mowing mechanism.
