SAFETY

General Information

This symbol means WARNING or PERSONAL SAFETY

INSTRUCTION - read the instruction be-

cause if has to do with your safety. Failure

to comply with the instruction may result in

personal injury or even death.

This manual is intended as a service and

repair manual only. The safety instructions provided

herein are for troubleshooting, service, and repair of the

Toro Spreader/Sprayer. The Spreader/Sprayer and oper-

ator’s manual contains safety information and operating

tips for safe operating practices. Operator’s manuals are

available through your Toro parts source or:

Think Safety First

Avoid injury due to inferior parts...

Use only original equipment parts to ensure that import-

ant safety criteria are met.

Avoid injury to bystanders...

Always clear the area of bystanders before starting or

testing powered equipment.

Avoid injury due to projectiles...

Always clear the area of sticks, rocks, or any other de-

bris that could be picked up and thrown by the powered

equipment.

Avoid modications...

Never alter or modify any part unless it is a factory ap-

proved procedure.

Avoid unsafe operation...

Always test the safety interlock system after making

adjustments or repairs on the machine. Refer to the

Electrical section in this manual for more information.

Avoid unexpected starting of engine...

Always turn off the engine and disconnect the spark plug

wire(s) before cleaning, adjusting, or repair.

Avoid lacerations and amputations...

Stay clear of all moving parts whenever the engine is

running. Treat all normally moving parts as if they were

moving whenever the engine is running or has the po-

tential to start.

Avoid burns...

Do not touch the engine, mufer, or other components

which may increase in temperature during operation,

while the unit is running or shortly after it has been run-

ning.

Avoid res and explosions...

Avoid spilling fuel and never smoke while working with

any type of fuel or lubricant. Wipe up any spilled fuel

or oil immediately. Never remove the fuel cap or add

fuel when the engine is running. Always use approved,

labeled containers for storing or transporting fuel and

lubricants.

Avoid asphyxiation...

Never operate an engine in a conned area without

proper ventilation.

Avoid injury from batteries...

Battery acid is poisonous and can cause burns. Avoid

contact with skin, eyes, and clothing. Battery gases can

explode. Keep cigarettes, sparks, and ames away from

the battery.

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 the 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 the

service manual. The following factors shall be

considered when applying torque: cleanliness of the

fastener, use of a thread sealant (Loctite), degree of

lubrication on the fastener, presence of a prevailing

torque feature, hardness of the surface underneath of

the fastener’s head, or similar condition which affects

the installation.

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.

Standard Torque for Dry, Zinc Plated, and Steel Fasteners (Inch Series)

Note: Reduce torque values listed in the table above

by 25% for lubricated fasteners. Lubricated fasteners

are defined as threads coated with a lubricant such as

oil, graphite, or thread sealant such as Loctite.

Note: Torque values may have to be reduced when

installing fasteners into threaded aluminum or brass.

The specific torque value should be determined based

on the fastener size, the aluminum or base material

strength, length of thread engagement, etc.

Note: The nominal torque values listed above for

Grade 5 and 8 fasteners are based on 75% of the

minimum proof load specified in SAE J429. The

tolerance is approximately ± 10% of the nominal

torque value. Thin height nuts include jam nuts.

Maintenance

WARNING

While you are maintaining or adjusting the machine,

someone could start the engine. Accidentally starting

the engine could seriously injure you or other

bystanders.

Remove the key from the ignition switch, engage

parking brake, and pull the wire(s) off the spark plug(s)

before you do any maintenance. Also push the wire(s)

aside so it does not accidentally contact the spark

plug(s).

WARNING

The engine can become very hot. Touching a hot

engine can cause severe burns.

Allow the engine to cool completely before service or

making repairs around the engine area.

Recommended Maintenance Schedule(s)

Maintenance Service

Interval

Maintenance Procedure

Before each use or daily

• Check the engine-oil level.

• Check the safety interlock system.

• Test the starter interlock.

• Check the machine for loose hardware.

• Check air cleaner; replace if dirty (may need more often under severe conditions).

• Clean the engine and the exhaust system area.

• Clean the grass and debris buildup from the machine.

After each use

• Clean and lubricate the spreader.

• Clean the sprayer tank.

• Clean the strainer.

• Clean the sprayer nozzles.

Every 50 hours

• Clean the foam air-cleaner element (more often under severe conditions).

• Check the pressure in the tires.

• Service the transaxle.

• Check sprayer system.

Every 80 hours

• Remove the engine shrouds and clean the cooling ns.

Every 100 hours

• Lubricate the grease ttings.

• Replace the dual element air lter.

• Change the engine oil.

• Change the engine oil (more often under severe condition).

• Check, clean and gap the spark plug.

Every 200 hours

• Service the spark arrester.

Monthly

• Clean the fuel sediment cup.

• Service the fuel strainer.

• Check the battery.

Yearly

• Torque the axle bolts.

Procedures

CAUTION

Raising the machine for service or maintenance

relying solely on mechanical or hydraulic jacks could

be dangerous. The mechanical or hydraulic jacks may

not be enough support or may malfunction allowing

Do not rely solely on mechanical or hydraulic jacks for

support. Use adequate jack stands or equivalent

support.

Preparing Machine for

Maintenance

Perform the following before servicing, cleaning, or making

any adjustments to the machine.

1. Move the machine to a level surface.

2. Shut off the engine, set the parking brake, wait for

all moving parts to stop.

3. Remove the key from the key switch.

Servicing the Spark Plug

Service Interval: Every 100 hours

Spark Plug Type: NGK BR6HS, Champion RTL86C, or

equivalent

Air Gap: 0.6 to 0.7 mm (0.02 to 0.03 inch)

Make sure the air gap between the center and side

electrodes is correct before installing the spark plug.

Use a spark plug wrench for removing and installing the

spark plug(s) and a gapping tool/feeler gauge to check and

adjust the air gap. Install a new spark plug(s) if necessary.

Removing the Spark Plug

1. Stop the engine, set the parking brake, remove the

key, and wait for all moving parts to stop before

leaving the operating position.

Checking the Spark Plug

Important:

Do not clean the spark plug(s). Always

replace the spark plug(s) when it has a black coating,

worn electrodes, an oily film, or cracks.

If you see light brown or gray on the insulator, the engine

is operating properly. A black coating on the insulator

usually means the air cleaner is dirty.

Set the gap to 0.6 to 0.7 mm (0.02 to 0.03 inch).
