1.6 Driving speed
Depending on quantity, size and character of vegetation and working conditions the recommended driving speed is 4 – 8
km./h. (2,5 – 5 M.P.H.)
1.7 Gearbox
Before operating the machine and further at regular intervals, the following points should be checked:
•
Oil level:
This is correct when the oil comes out of the bottom hole (red arrow) of
the oil level plug. This plug is hidden behind the protection cover on the
PTO side.
•
Breather:
The air vent (red arrow) must not be clogged. The convex cap must be
easy to press. Clean if necessary by blowing through the air vent from the
“inside”.
Renew oil after the first 20 working hours and further after every 100 working hours, but at least once a season.
To renew the gearbox oil handle as follows:
Remove the breather and the drain plug and drain the oil.
***
Collect the old oil, e.g. in a bucket, for environment friendly disposal
.
***
Refit the oil drain-plug and pour 1 liter (± 1/2 gallon) diesel-oil through the breather hole in the housings. Clean the
internal gearbox (by washing with the diesel oil) by turning the V-belt pulley a few times by hand.
Then
drain and collect
the dirty diesel-oil and refill the gearbox to the required oil-level and refit the breather.
Fill up only to the proper level and use always the same oil.
Recommended is synthetic gear-oil EP-320.
*** Note: Allow the oil enough time to sink through the bearings.
Wipe off excess oil to prevent it reaching the V-belts as oil and grease cause unnecessary slipping and extra wear.
To replenish or replace the correct oil, if possible Mobil EP-320 or an equivalent oil.
Viscosity base oil at 40°C 320 Cst.
Temperature range -24°C tot 240°C
DIN 51517-3 : CLP PG
ISO 12925-1 CKT
Good pressure properties.
1.8 V-belts
A correct V-belt tension is very important and this should be checked after the
first 2, 8 and 16 hours
of service and further on at regular times (at least every
50 hours of service). As a general rule when determining the correct tension, the
V-belts must not be able to turn more than one ¼ turn around their longitudinal
axis.
The V-belts are kept in tension by means of a spring loaded jockey pulley. The
"pressure" of this jockey pulley can be adjusted by the chain of the spring and the
hook on the frame.
Remark: When new V-belts are mounted, always make a test run and check the V-belt tension
again!!!
