Maintenance Safety
•
Before servicing or adjusting the machine, stop the
machine, shut off the engine, engage the parking
brake, remove the key, and wait for all moving
parts to stop.
•
Perform only those maintenance instructions
described in this manual. If major repairs are
ever needed or assistance is desired, contact an
authorized Toro distributor.
•
Ensure that the machine is in safe operating
condition by keeping nuts, bolts, and screws tight.
•
If possible, do not perform maintenance while the
engine is running. Keep away from moving parts.
•
Do not check or adjust the chain tension when the
vehicle engine is running.
•
Carefully release pressure from components with
stored energy.
•
Support the machine with blocks or storage stands
when working beneath it. Never rely on the
hydraulics on the vehicle to support the machine.
•
After maintaining or adjusting the machine, ensure
that all guards are installed.
Lubrication
Service Interval: Every 25 hours
The machine has 5 grease fittings that must be
lubricated with a No. 2 lithium grease.
The grease fitting locations ( Figure 21 ) and quantities
are: Roller shaft bearings (4) and Brush shaft bearing
(1).
Important:
Lubricate the bearings to maintain a
slight leakage between bearings and housings.
Too much grease can cause overheating.
Note:
We do not recommend lubricating the drive
chain unless it becomes stiff because of rust. If the
chain rusts, you can lubricate it lightly with a dry-type
lubricant.

Hydraulic System Safety
•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
•
Use cardboard or paper to find hydraulic leaks.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
