General Information

This symbol means WARNING or

PERSONAL SAFETY INSTRUCTION -

read the instruction because it 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 30”

Think Safety First

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.

Avoid injury due to inferior parts...

Use only original equipment parts to ensure that

important 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

debris 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

approved 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

potential 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

running.

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.

Torque Specications

Inch Series bolts and Screws

(A) Grade 1 & 2

(B) Grade 5

(C) Grade 8

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 identied and

specied in the service manual.

These torque specications for the installation and

tightening of fasteners shall apply to all fasteners

which do not have a specic requirement identied

in the service manual. The following factors shall be

consid ered 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, 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 specic 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 per-

formed 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 & Steel Fasteners (Inch Series)

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.

Lubricate Caster Wheel Hubs

Service Interval: Yearly

1. Stop engine, wait for all moving parts to stop, and

remove key. Engage parking brake.

2. Remove caster wheel from caster forks.

3. Remove seal guards from the wheel hub (Fig. 002).

4. Remove one of the spacer nuts from the axle

assembly in the caster wheel (Fig. 002). Note that

thread locking adhesive has been applied to lock the

spacer nuts to the axle. Remove the axle (with the

other spacer nut still assembled to it) from the wheel

assembly.

5. Pry out seals, and inspect bearings for wear or

damage and replace if necessary.

6. Pack the bearings with a NGLI grade #1 multi-

purpose grease.

7. Insert one bearing, one new seal into the wheel.

Note: Replace the seals.

8. If the axle assembly has had both spacer nuts

removed (or broken loose), apply a thread locking

adhesive to one spacer nut and thread onto the

axle with the wrench ats facing outward. Do not

thread spacer nut all of the way onto the end of

the axle. Leave approximately 3mm (1/8”) from the

outer surface of the spacer nut to the end of the axle

inside the nut.

9. Insert the assembled nut and axle into the wheel on

the side of the wheel with the new seal and bearing.

10. With the open end of the wheel facing up, ll the

area inside the wheel around the axle full of NGLI

grade #1 multi-purpose grease.

11. Insert the second bearing and new seal into the

wheel.

12. Apply a thread locking adhesive to the 2nd spacer

nut and thread onto the axle with the wrench ats

facing outward.

13. Torque the nut to 75-80 in-lbs. (8-9 Nm), loosen,

then re-torque to 20-25 in-lbs. (2-3 Nm). Make sure

axle does not extend beyond either nut.

14. Reinstall the seal guards over the wheel hub and

insert wheel into caster fork. Reinstall caster bolt and

tighten nut fully.

Important: To prevent seal and bearing damage,

check the bearing adjustment often. Spin the

caster tire. The tire should not spin freely

(more than 1 or 2 revolutions) or have any side

play. If the wheel spins freely, adjust torque on

spacer nut until there is a slight amount of drag.

Reapply thread locking adhesive.

CALIFORNIA

Proposition 65 Warning

Battery posts, terminals, and related

accessories contain lead and lead compounds,

chemicals known to the State of California to

cause cancer and reproductive harm.

Wash hands after handling.

Allowing batteries to stand for an extended period of

time without recharging them will result in reduced

performance and service life. To preserve optimum

battery performance and life, recharge batteries in

storage when the open circuit voltage drops to 12.4

volts.

Note: To prevent damage due to freezing, battery

should be fully charged before putting away

for winter storage.

Check the voltage of the battery with a digital voltmeter.

Locate the voltage reading of the battery in the table and

charge the battery for the recommended time interval

to bring the charge up to a full charge of 12.6 volts or

greater.

Important: Make sure the negative battery cable

is disconnected and the battery charger used

for charging the battery has an output of 16

volts and 7 amps or less to avoid damaging the

battery.
