Belt Maintenance

Adjusting the Alternator
Belt
Service Interval: After the first 8 hours
Ensure that the belt is properly tensioned to ensure
proper operation of the machine and prevent
unnecessary wear.
1. Shut off the engine, set the parking brake, and
remove the ignition key.
2. Apply moderate thumb pressure to the belt
between the pulleys (10 kg or 22 lb). The belt
should deflect 7 to 9 mm (0.28 to 0.35 inch). If
not, complete the following procedure to adjust
the belt tension:

3. Adjusting strap
A. Loosen the bolts securing the alternator to
the engine and adjusting strap.
B. Inspect the belt for wear or damage and
replace if it is worn.
C. Using a lever placed between the alternator
and the engine block, pull the alternator out
to obtain the correct belt tension and tighten
the bolts.
Hydraulic System
Maintenance

Hydraulic System Safety

•
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.
•
Seek immediate medical attention if fluid
is injected into skin. Injected fluid must be
surgically removed within a few hours by a
doctor.
Servicing the Hydraulic
Fluid
Checking the Hydraulic-Fluid
Level
The hydraulic-fluid reservoir is filled at the factory with
approximately 20.8 L (5.5 US gallons) of high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before operating the machine each day. Depending
on your machine, you can use the white plastic
g014755
window on the front of the hydraulic-fluid reservoir
(behind the seat on the left side) or the dipstick on
the top of the tank to check the fluid level. The fluid
should be between the lines in the window or the 2
marks on the dipstick; if not, add an appropriate fluid
as described in the following sections:
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
5-gallon pails or 55-gallon drums. See parts catalog or
Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We
do not recommend the use of synthetic fluid. Consult
with your lubricant distributor to identify a satisfactory
product.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
