Servicing the Spark Arrestor
Muffler
Every 200 hours operation, clear the muffler of carbon
buildup.
1. Remove the pipe plug from the clean-out port at the
lower side of the muffler.
Caution
The muffler may be hot and could cause injury.
Be careful while working around the muffler.
2. Start the engine. Plug the normal muffler exit with a
block of wood or metal plate so that the exhaust flow
will be forced out of the clean-out port. Continue to
block the exit until carbon deposits cease coming out of
the port.
Caution
Do not stand in line with the clean-out port.
Always wear safety glasses.
3. Stop the engine and replace the pipe plug.

Changing the Hydraulic Fluid

Change the hydraulic fluid after every 800 operating hours,
in normal conditions. If the 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 case return line from the bottom of the
reservoir and let the hydraulic fluid flow into a large
drain pan. Connect the line when the hydraulic fluid
stops draining.
3. Fill the reservoir with approximately 7.5 gallons of
hydraulic fluid; refer to Checking the Hydraulic Fluid,
page 17.
Important Use only the hydraulic fluids specified.
Other fluids could cause system damage.
4. Install the reservoir cap. Start the engine and use all of
the hydraulic controls to distribute hydraulic fluid
throughout the system. Also check for leaks; then stop
the engine.
5. Check the fluid level and add enough to raise level the
level to the FULL mark on the dipstick. Do not overfill.

Replacing the Hydraulic Filters

Change the 2 hydraulic filters initially after the first 200
operating hours. Thereafter, change the filters after every
800 operating hours, in normal conditions.
Use Toro replacement filters Part No. 94-2621 for the rear
(cutting unit) of the machine and 75-1310 for the front
(charge) of the machine.
Important Use of any other filter may void the
warranty on some components.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brakes, and remove the ignition key.
