Fieldmann FZR 4610-B: 9. MAINTENANCE

Maintenance

In general, following instructions apply:

– too low mowing causes disturbation of roots and follow-up “spotted” appearance;

– in summer, mowing has to be higher in order to prevent soil desiccation;

– mowing wet grass may cause knife efficiency reductionowing to grass sticking to the knife

and pulling-out grass vegetation;

– in a case of extraordinarily high grass, it is advisable to carry out the first mowing with

maximal allowed height and then to carry outthe second mowing after two or three days.

A lawn will have a better appearance thanks to regular and full-area uniform height mowing

and alternation of two directions

Maintenance

All nuts, pins and bolts must be tightened properly so that the Device is in a safe and

serviceable condition. Regular maintenance is a basic precondition to ensure user’s safety, to

keep serviceability and high performance of the mower.

Never store the device with gasoline in the tank inside a building where vapours might reach

open fire, sparks or a high temperature source.

Let the engine cool down before storing in any enclosed area.

To reduce fire risk make sure that the mower and especially the engine, exhaust muffler,

batteries and also a place for storage of spare gasoline are cleaned from rests of grass,

leaves or excessive amount of grease.

Check the deflector and collection basket condition regularly; replace in a case of damage.

Perform fuel draining in a well ventilated area while the engine is cooled-down.

Wear thick working gloves when removing or installing the mowing knife.

After every sharpening of the mowing knife blade, its counterbalancing needs to be checked.

WARNING! Before performing maintenance or repair, switch-off the engine and disconnect

the spark plug.

Before using the four-stroke engine, please, read the engine operation manual carefully.

Check the oil level regularly, fill-up or change if needed.

Check the mower regularly and make sure that all grass deposits in the bottom part of the

bogie are removed.

Lubricate the bogie shaft and bearings with suitable grease regularly.

Check the condition of the knives regularly, as they influence the mower output substantially.

Knives should always be sharp and counterbalanced.

Check tightening of all bolts and nuts in regular intervals. Worn-down or improperly tightened

nuts and bolts may cause serious damage to the engine or the frame.

If the knife hits an obstacle hardly, stop the mower and transport it to an authorized service

station.

KNIFE: The knife is made of pressed steel. To achieve as good mowing as possible, grind

the knife regularly, approximately after every 25 hours of operation. Make sure the knife is

always counterbalanced well. For this purpose, insert a small iron axis (of 2-3mm diameter)
