the friction device on the throttle lever. The
maximum force required to operate the throttle
lever should be 27 Nm.
CAUTION
Before servicing or making adjustments to
the machine, stop the engine and remove the
key from the switch.
Changing Hydraulic Fluid
Change hydraulic fluid after every400 operating
hours, in normal conditions. If fluid becomes
contaminated, contact your local TORO distributor
because the system must be flushed. Contaminated
fluid looks milky or black when compared to clean
oil.
1. Turn the engine off and raise the hood.
2. Disconnect the hydraulic line or remove the
hydraulic filter and let hydraulic fluid flow into
a drain pan. Reinstall the line when hydraulic
fluid stops draining.

IMPORTANT: Use only hydraulic fluids
specified. Other fluids could cause system
damage.
4. Install the reservoir cap. Start the engine and
use all hydraulic controls to distribute hydraulic
fluid throughout the system. Also check for
leaks. Then stop the engine.
5. Check the level of fluid and add enough to raise
the level to the FULL mark on the dipstick. DO
NOT OVER FILL.
Replacing The Hydraulic Filter
The hydraulic system filter must be changed
initially, after the first 10 hours of operation, and
thereafter every 200 hours of operation or yearly,
whichever comes first. Use a genuine Toro oil filter
for replacement. The hydraulic oil must be
changed every 400 hours of operation or yearly,
