Adjusting the Throttle

1. Position the throttle lever rearward so that it
stops against the control-panel slot.
2. Loosen the throttle-cable connector on the
injection-pump-lever arm

1. Injection-pump-lever arm
3. Hold the injection-pump-lever arm against the
low-idle stop and tighten the cable connector.
4. Loosen the screws securing the throttle control
to the control panel.
5. Push the throttle-control lever completely
forward.
6. Slide the stop plate until it contacts the throttle
lever and tighten the screws securing the throttle
control to the control panel.
7. If the throttle does not stay in position during
operation, torque the locknut, used to set the
friction device on the throttle lever, to 5 to 6 N∙m
(40 to 55 in-lb).
Note:
The maximum force required to operate
the throttle lever should be 27 N∙m (20 in-lb).

Hydraulic System
Maintenance

Hydraulic System Safety

WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• 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.
Checking the Hydraulic
System
Service Interval: Before each use or daily—Check
the hydraulic-fluid level.
The machines reservoir is filled at the factory with
approximately 13.2 L (3.5 US gallons) of high-quality
hydraulic fluid. Check the level of the hydraulic
fluid before the engine is first started and daily
thereafter. The recommended replacement fluid
is Toro Premium All-Season Hydraulic Fluid
(Available in 19 L (5 US gallons) pails or 55-gallon
drums. See the parts catalog or Toro distributor for
part numbers.)
Alternate fluids: If the Toro fluid is not available,
you may use other fluids provided they meet all
the following material properties and industry
specifications. Do not use 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.
