Changing Hydraulic Oil And Filter; Lubrication - Toro Greensmaster 3200 Service Manual

Changing Hydraulic Oil and Filter

Change hydraulic filter initially after the first 50 operating
hours, thereafter change hydraulic oil and filter after ev-
ery 800 hours. If oil becomes contaminated, contact
your local TORO distributor because the system must
be flushed. Contaminated oil looks milky or black when
compared to clean oil.
Note: If oil is not going to be drained, disconnect and
plug hydraulic line going to filter.
1. Clean area around filter mounting area. Place drain
pan under filter and remove filter.
2. Fill the replacement filter with hydraulic fluid (see
Check Hydraulic System Fluid), lubricate the sealing
gasket and hand turn until gasket contacts filter head.
Then tighten 3/4 turn further. Filter should now be
sealed.
3. Fill hydraulic reservoir with approximately 5.5 gal-
lons of hydraulic oil (see Check Hydraulic System Fluid).
4. Start the machine and run it at idle for 3 to 5 minutes
to circulate the fluid and remove any air trapped in the
system. Stop the machine and recheck the fluid level.
5. Dispose of hydraulic fluid properly.

Lubrication

CAUTION
Before servicing or making adjustments to
the machine, stop engine and remove key
from the switch.
The traction unit has grease fittings that must be lubri-
cated regularly with No. 2 General Purpose Lithium
Base Grease. If machine is operated under normal
conditions, lubricate all bearings and bushings after ev-
ery 50 hours of operation. Lubricate fittings immedi-
ately after every washing, regardless of the interval
listed.
The traction unit pedal pivot bushing must be lubri-
cated). The grease fitting is located under the foot plate
and is connected to the pedal.
1. Wipe grease fitting clean so foreign matter cannot
be forced into the bearing or bushing.
2. Pump grease into the bearing or bushing.
