Maintenance And Service - Toro Groundsmaster 580-D Service Manual

Maintenance and Service

21. Before servicing or making adjustments, stop en-
gine and remove key from the switch.
22. Assure entire machine is properly maintained and in
good operating condition. Frequently check all nuts,
bolts and screws.
23. Frequently check all hydraulic line connectors and
fittings. Assure all hydraulic hoses and lines are in good
condition before applying pressure to the system.
24. If the Groundsmaster 580--D loses power and
needs to be moved, either by--pass the hydraulic pump
or unlock the front wheel hubs. Unlocking the front
wheels disables the machine braking system. Block the
wheels before unlocking the hubs to keep the machine
from moving. To tow the machine, connect to the towing
vehicle with a rigid towing device. Do not use chains,
cables or other non--rigid devices for towing. Lock the
hubs when towing is completed.
25. Keep body and hands away from pin hole leaks or
nozzles that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury. Fluid accidentally injected into the skin
must be surgically removed within a few hours by a doc-
tor or gangrene may occur.
26. Before any hydraulic system maintenance, stop en-
gine and lower cutting units to the ground so all pressure
is relieved.

ing parts. Keep everyone away.

tor check maximum engine speed.

battery voltage is required for troubleshooting or test
procedures, temporarily connect the battery.
