General Safety Instructions
The Reelmaster has been tested and certified by Toro
for compliance with existing safety standards and specifications. Although hazard control and accident prevention partially are dependent upon the design and
configuration of the machine, these factors are also dependent upon the awareness, concern and proper training of the personnel involved in the operation, transport,
maintenance and storage of the machine. Improper use
or maintenance of the machine can result in injury or
death. To reduce the potential for injury or death, comply
with the following safety instructions.
Before Operating
WARNING
To reduce the potential for injury or death,
comply with the following safety instructions.
1. Review and understand the contents of the Operator’s Manuals and Operator’s DVD before starting and
operating the vehicle. Become familiar with the controls
and know how to stop the vehicle and engine quickly.
Additional copies of the Operator’s Manual are available
on the internet at www.Toro.com.
2. Keep all shields, safety devices and decals in place.
If a shield, safety device or decal is defective, illegible or
damaged, repair or replace it before operating the machine. Also tighten any loose nuts, bolts or screws to ensure machine is in safe operating condition.
3. Assure interlock switches are adjusted correctly so
engine cannot be started unless traction pedal is in
NEUTRAL and cutting units are DISENGAGED.
While Operating
1. Sit on the seat when starting and operating the machine.
2. Before starting the engine:
A. Engage the parking brake.
4. Since diesel fuel is flammable, handle it carefully:
A. Use an approved fuel container.
B. Do not remove fuel tank cap while engine is hot or
running.
C. Do not smoke while handling fuel.
D. Fill fuel tank outdoors and only to within an inch of
the top of the tank, not the filler neck. Do not overfill.
E. Wipe up any spilled fuel.
4. Do not touch engine, exhaust system components or
radiator while engine is running or soon after it is
stopped. These areas could be hot enough to cause
burns.
5. Before getting off the seat:
B. Make sure traction pedal is in neutral and the
PTO switch is OFF (disengaged).
C. After engine is started, release parking brake and
keep foot off traction pedal. Machine must not move.
If movement is evident, the traction pedal linkage
may be adjusted incorrectly; therefore, shut engine
off and adjust traction pedal linkage until machine
does not move when traction pedal is released.
3. Do not run engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
A. Ensure that traction pedal is in neutral.
B. Engage parking brake.
C. Disengage PTO and wait for cutting unit reels to
stop rotating.
D. Stop engine and remove key from ignition switch.
E. Toro recommends that anytime the machine is
parked (short or long term), the cutting units should
be lowered to the ground. This relieves pressure
from the lift circuit and eliminates the risk of cutting
units accidentally lowering to the ground.
F. Do not park on slopes unless wheels are chocked
or blocked.

Maintenance and Service
1. The Traction Unit and Cutting Unit Operator’s Manuals provide information regarding the operation, general
maintenance and maintenance intervals for your Reelmaster machine. Refer to these publications for additional information when servicing the machine.
2. Before servicing or making adjustments, lower cutting units, stop engine, set parking brake and remove
key from the ignition switch.
3. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
4. Never store the machine or fuel container inside
where there is an open flame, such as near a water heater or furnace.
5. Make sure all hydraulic line connectors are tight and
all hydraulic hoses and lines are in good condition before applying pressure to the hydraulic system.
6. Keep body and hands away from pin hole leaks in hydraulic lines that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury. Fluid accidentally injected into the skin
must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
7. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be relieved by stopping engine and lowering cutting units to
the ground.
8. If major repairs are ever needed or assistance is desired, contact an Authorized Toro Distributor.
9. To reduce potential fire hazard, keep engine area
free of excessive grease, grass, leaves and dirt. Clean
protective screen on machine frequently.
10.If engine must be running to perform maintenance or
an adjustment, keep hands, feet, clothing and other
parts of the body away from cutting units and other moving parts. Keep bystanders away.
11.To assure safety and accuracy, check maximum engine speed.
12.Shut engine off before checking or adding oil to the
engine crankcase.
13.Disconnect battery before servicing the machine.
Disconnect negative battery cable first and positive
cable last. If battery voltage is required for troubleshooting or test procedures, temporarily connect the battery.
Reconnect positive battery cable first and negative
cable last.
14.Battery acid is poisonous and can cause burns.
Avoid contact with skin, eyes and clothing. Protect your
face, eyes and clothing when working with a battery.
15.Battery gases can explode. Keep cigarettes, sparks
and flames away from the battery.
16.When welding on machine, disconnect both battery
cables to prevent damage to machine electronic equipment. Disconnect negative battery cable first and positive cable last. Also, disconnect the wire harness
connector from th e m achine TEC controller and disconnect the terminal connector from the alternator.
17.At the time of manufacture, the machine conformed
to the safety standards for riding mowers. To assure optimum performance and continued safety certification of
the machine, use genuine Toro replacement parts and
accessories. Replacement parts and accessories made
by other manufacturers may result in non-conformance
with the safety standards and the warranty may be
voided.
18.When changing attachments, tires or performing
other service, use correct jacks, hoists and jack stands.
Make sure machine is parked on a solid level surface
such as a concrete floor. Prior to raising the machine, remove any attachments that may interfere with the safe
and proper raising of the machine. Always chock or
block wheels. Use appropriate jack stands to support
the raised machine. If the machine is not properly supported by jack stands, the machine may move or fall,
which may result in personal injury (see Jacking Instructions in this chapter).
19.Make sure to dispose of potentially harmful waste
(e.g. fuel, oil, engine coolant, filters, battery) in an environmentally safe manner . Follow all local codes and regulations when recycling or disposing of waste.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and specified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Service Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature
(e.g. Nylock nut), hardness of the surface underneath
the fastener’s head or similar condition which affects th e
installation.
Fastener Identification
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread engagement, etc.
The standard method of verifying torque shall be performed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.

Inch Series Bolts and Screws
Figure 1
Using a Torque Wrench with an Offset Wrench
Use of an offset wrench (e.g. crowfoot wrench) will affect
torque wrench calibration due to the effective change of
torque wrench length. When using a torque wrench with
an offset wrench, multiply the listed torque recommendation by the calculated torque conversion factor
(Fig. 3) to determine proper tightening torque. Tightening torque when using a torque wrench with an offset
wrench will be lower than the listed torque recommendation.
Example: The measured effective length of the torque
wrench (distance from the center of the handle to the
center of the square drive) is 18”.
The measured effective length of the torque wrench with
the offset wrench installed (distance from the center of
the handle to the center of the offset wrench) is 19”.
