This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and even death. Danger, Warning, and Caution are
signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.

Safety
This machine meets or exceeds CEN standard EN
836:1997, ISO standard 5395:1990, and ANSI
B71.4-1999 specifications in effect at time of production,
when ballast is installed according to the chart on
page 19.
• Never mow while people, especially children, or pets
are nearby.
• Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
• Do not carry passengers.
• All drivers and mechanics should seek and obtain
professional and practical instruction. The owner is
responsible for training the users. Such instruction
should emphasize:
– the need for care and concentration when working
with ride-on machines;
– control of a ride-on machine sliding on a slope will
not be regained by the application of the brake. The
main reasons for loss of control are:
• insufficient wheel grip;
• being driven too fast;
• inadequate braking;
• the type of machine is unsuitable for its task;
• lack of awareness of the effect of ground
conditions, especially slopes;
• incorrect hitching and load distribution.
• The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people, or property.
Improper use or maintenance by the operator or owner
can result in injury. To reduce the potential for injury,
comply with these safety instructions and always pay
attention to the safety alert symbol, which means

• While mowing, always wear substantial footwear, long
trousers, hard hat, safety glasses, and ear protection.
Long hair, loose clothing, or jewelry may get tangled in
moving parts. Do not operate the equipment when
barefoot or wearing open sandals.
• Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
mower is designed for this purpose.
• Stay alert for holes in the terrain and other hidden
hazards.
• Use care when pulling loads or using heavy equipment.
– Use only approved drawbar hitch points.
• Warning—Fuel is highly flammable. Take the
following precautions:
– Store fuel in containers specifically designed for this
purpose.
– Refuel outdoors only and do not smoke while
refuelling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel while the engine
is running or when the engine is hot.
– If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of
spillage and avoid creating any source of ignition
until fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Replace faulty silencers/mufflers.
• Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments approved
by the manufacturer.
• Check that operator’s presence controls, safety switches
and shields are attached and functioning properly. Do

on grass slopes requires particular care. To guard
against overturning:
– do not stop or start suddenly when going up or
downhill;
– engage clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
• Disengage drive to attachments when transporting or
not in use.
• Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher/catchers;
– before making height adjustment unless adjustment
can be made from the operator’s position.
– before clearing blockages;
– before checking, cleaning or working on the mower;
– after striking a foreign object or if an abnormal
vibration occurs. Inspect the mower for damage and
make repairs before restarting and operating the
equipment.

• Reduce the throttle setting during engine run-out and, if
the engine is provided with a shut-off valve, turn the
fuel off at the conclusion of mowing.
• Keep hands and feet away from the cutting units.
• Look behind and down before backing up to be sure of
a clear path.
• Slow down and use caution when making turns and
crossing roads and sidewalks. Stop cylinders/reels if not
mowing.
• Do not operate the mower under the influence of
alcohol or drugs
• Use care when loading or unloading the machine into a
trailer or truck
• Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Never store the equipment with fuel in the tank inside a
building where fumes may reach an open flame or
spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine,
silencer/muffler, battery compartment and fuel storage
area free of grass, leaves, or excessive grease.
• Carefully release pressure from components with stored
energy.
• Disconnect battery and remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last.
• Use care when checking the cylinders/reels. Wear
gloves and use caution when servicing them.
• Keep hands and feet away from moving parts. If
possible, do not make adjustments with the engine
running.

Shut the engine off before emptying the baskets.
• Raise the cutting units when driving from one work
area to another.
• Do not touch the engine, silencer/muffler, or exhaust
pipe while the engine is running or soon after it has
stopped because these areas could be hot enough to
cause burns.
• Stay clear of the rotating screen at the side of the engine
to prevent direct contact with your body or clothing.
• If the engine stalls or loses headway and cannot make it
to the top of a slope, do not turn the machine around.
Always back slowly, straight down the slope.
• When a person or pet appears unexpectedly in or near
the mowing area, stop mowing. Careless operation,
combined with terrain angles, ricochets, or improperly
positioned guards can lead to thrown object injuries. Do
not resume mowing until the area is cleared.

• Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury. Seek immediate medical attention if fluid is
injected into skin.
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
• Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts, especially the screen at the side of the

Adjusting the Turf
Lifted Height of Outer Front
Compensation Spring
Note: This adjustment is needed for Cutting Unit Models
03527 and 03528 only.
The turf compensation spring (Fig. 12), connecting carrier
frame to cutting unit, controls the amount of fore-aft
rotation available.
The Turf Compensation Spring also transfers weight from
the front to rear roller. (This helps to reduce a wave pattern
in the turf, also known as bobbing.)
Important Make spring adjustments with cutting unit
mounted to traction unit and lowered to shop floor.
1. Tighten locknut on rear of spring rod until the gap (C)
between rear of spring bracket and front of washer is
1.25 in. (32 mm) (Fig. 12).
2. Tighten hex nuts on front end of spring rod until the
compressed length (A) of spring is 6.25 in. (328 mm)
(Fig. 12).
Note: As compressed spring length (A) decreases, weight
transfer from front roller to rear roller increases and carrier
frame/cutting unit rotation angle (B) decreases.
Note: As gap (C) between spring bracket and washer
increases, carrier frame/cutting unit rotation angle (B)
increases.
Cutting Units (Enable Position)
The turnaround height of the front outer cutting units (#4 &
#5) may be increased to provide additional ground
clearance on contoured fairways. Contact your distributor
for assistance.
Note: The RM CONFIG time delay should not be changed
from the original setting of 0 when using this method to
adjust turn around height.
To increase the turn around height of the front cutting units
proceed as follows:
• Position machine on a level surface, lower the cutting
units and stop the machine.
• Loosen the carriage bolt nut securing the lift arm switch
bracket to the No. 4 lift arm (left front) (Fig. 13).
• Move the lift switch bracket inward in the slot until the
desired position is attained.
• Set the distance between the lift arm switch and the flag
on the lift arm to approximately .062 inches.
• Tighten the carriage bolt nut.

Checking the Engine Oil
The engine is shipped with oil in the crankcase; however,
the oil level must be checked before and after the engine is
first started.
Crankcase capacity is approximately 4 qt. (2.8 l) with the
filter.
Use high-quality engine oil that meets the following
specifications:
API Classification Level Required: CH–4, CI–4 or
higher.
Preferred oil: SAE 15W–40 (above 0_ F)
Alternate oil: SAE 10W–30 or 5W–30
(all temperatures)
Toro Premium Engine oil is available from your distributor
in either 15W–40 or 10W–30 viscosity. See the parts
catalog for part numbers.
1. Park machine on a level surface, stop engine, and
remove key from ignition switch. Open hood.

1. Dipstick2. Oil fill cap
3. If oil is below FULL mark, remove fill cap and add oil
until level reaches FULL mark on dipstick. Do not
overfill.
4. Install oil fill cap and close hood.
Important Be sure to keep the engine oil level between
the upper and lower limits on the oil gauge. Engine failure
may occur as a result of over filling or under filling the
engine oil.
Checking the Cooling System
Clean debris off screen, oil cooler and front of radiator
daily, more often if conditions are extremely dusty and
dirty; refer to section on Engine Cooling System.
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check level of
coolant in expansion tank at beginning of each day before
starting the engine. Capacity of cooling system is 9.6
quarts.
2. Remove dipstick, wipe clean, and reinstall dipstick.
Remove dipstick and check oil level on dipstick; Oil
level should be up to FULL mark (Reelmaster
5200—Fig. 14, Reelmaster 5400—Fig. 15).

Checking the Transmission
Fluid
The front axle housing acts as the reservoir for the system.
The transmission and axle housing are shipped from the
factory with approximately 5 quarts of Mobil 424 hydraulic
fluid. However, check level of transmission oil before
engine is first started and daily thereafter.
1. Position machine on a level surface, lower the cutting
units and stop the engine.
2. Remove floor panel.
3. Unscrew dipstick cap from the transmission filler neck
(Fig. 18) and wipe it with a clean rag. Screw dipstick
into filler neck. Remove the dipstick and check level of
oil. If level is not within 1/2 inch from the groove in the
dipstick, add enough oil to raise level to groove mark.
Do not overfill by more than 1/4 inch above groove.
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1/4 to 1/2 in. (6
to 13 mm) below the bottom of the filler neck.
This empty space in the tank allows the fuel to
expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.

Checking the Hydraulic Fluid
The machines reservoir is filled at the factory with
approximately 8 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 Transmission/Hydraulic Tractor
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
petroleum–based Universal Tractor Hydraulic Fluids
(UTHF) may be used provided its specifications fall within
the listed range for all the following material properties and
it meets industry standards. 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.
3. Remove dipstick from filler neck and wipe it with a
clean rag. Insert dipstick into filler neck; then remove it
and check level of fluid. Fluid level should be within
1/4 inch of mark on dipstick.
4. If level is low, add appropriate fluid to raise level to full
mark.
5. Install dipstick and cap onto filler neck.
Checking the Rear Axle
Lubricant
Note: This procedure is for Model 03544 only.

Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1/4 to 1/2 in. (6
to 13 mm) below the bottom of the filler neck.
This empty space in the tank allows the fuel to
expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
Note: Normally, engine should start after above bleeding
procedures are followed. However, if engine does not start,
air may be trapped between injection pump and injectors;
refer to Bleeding Air from the Injectors, page 39.
Setting the Reel Speed
To achieve a consistent, high quality-of-cut and a uniform
after cut appearance, it is important that the reel speed
controls (located under seat) be correctly set.
Adjust the reel speed controls as follows:
1. Select the height-of-cut at which the cutting units are
set.
2. Choose the desired ground speed best suited for
conditions.
3. Using the appropriate graph (Fig. 30) for 5 blade or 8
blade cutting units, determine the proper reel speed
setting.
Figure 30
4. To set reel speed, rotate knobs (Fig. 31) until indicator
arrows are in line with the number designating desired
setting.

Note: Reel speed can be increased or decreased to
compensate for turf conditions.
27
Adjusting the Lift Arm Down
Towing the Traction Unit
Pressure
The down pressure spring on each cutting unit lift arm can
be adjusted to compensate for different turf conditions.
Increased down pressure will help keep the cutting units on
the ground when mowing at higher speeds and helps
maintain a uniform height-of-cut in rough conditions or in
areas of thatch build up.
Each down pressure spring may be adjusted to one of four
settings. Each increment increases or decreases down
pressure on cutting unit by 8 lb.
1. Position machine on a level surface, lower the cutting
units, stop the engine, engage the parking brakes, and
remove key from ignition switch.
2. Remove floor plate in front of seat and open the hood to
gain access to all 5 springs.
Caution
Springs are under tension.
Use caution when adjusting.
3. Place an open end wrench on the hex shaft of the spring
bracket (Fig. 32).
4. Remove the capscrew and locknut securing retaining
bracket (Fig. 32), while rotating hex shaft to relieve
spring tension.
If it becomes necessary to tow the machine, tow it forward
only, for a short distance and at a speed no greater than 3
mph.
Important If these towing limits are exceeded, severe
damage to the hydrostatic transmission may occur.
To tow a disabled machine:
1. Loosen and remove capscrews securing the drive shaft
to the engine drive coupler. Loosen capscrews clamping
drive shaft to transmission (Fig. 33). Remove drive
shaft.

3. Attach the other end of the towing device to a vehicle
that is capable of towing the machine safely and at
speeds below 3 mph.
4. An operator must be on the machine to steer it and keep
the traction pedal fully depressed in the forward
position while towing.
5. When towing is completed, reinstall driveshaft as
shown in Figure 33. The splines are designed to allow
assembly only when the two halves of the shaft are
properly oriented.
Diagnostic Light
The RM 5200-D/5400-D is equipped with a diagnostic light
which indicates if the electronic controller is functioning
correctly. The green diagnostic light is located under the
control panel, next to the fuse block (Fig. 35). When the
electronic controller is functioning correctly and the key
switch is moved to the ON position, the controller
diagnostic light will be illuminated. The light will blink if
the controller detects a malfunction in the electrical system.
The light will stop blinking and automatically reset when
the key switch is turned to the OFF position.
• Fuses are blown.
• Not functioning correctly.
Check electrical connections, input fuses and diagnostic
light bulb to determine malfunction. Make sure loopback
connector is secured to wire harness connector.
Diagnostic ACE Display
The RM 5200-D/5400-D is equipped with an electronic
controller which controls most machine functions. The
controller determines what function is required for various
input switches (i.e. seat switch, key switch, etc.) and turns
on the outputs to actuate solenoids or relays for the
requested machine function.
For the electronic controller to control the machine as
desired, each of the input switches, output solenoids and
relays must be connected and functioning properly.
The Diagnostic ACE display is a tool to help the user verify
correct electrical functions of the machine.
Checking the Interlock
Switches
1
Figure 35
1. Electronic controller light
When the controller diagnostic light blinks, one of the
following problems has been detected by the controller:
• One of the outputs has been shorted.
• One of the outputs is open circuited.
Using the diagnostic display, determine which output is
malfunctioning; refer to Checking the Interlock Switches,
page 29.
If the diagnostic light is not illuminated when the key
switch is in the ON position, this indicates that the
electronic controller is not operating. Possible causes are:
• Loopback is not connected.
The purpose of the interlock switches are to prevent the
engine from cranking or starting unless the traction pedal is
in NEUTRAL, the Enable/Disable switch is in DISABLE
and the Lower Mow / Raise control is in the neutral
position. In addition, the engine will stop when the traction
pedal is depressed with operator off the seat.
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
• Replace switches every two years regardless of
whether they are operating properly or not.
Verifying Interlock Switch Function
1. Park machine on a level surface, lower the cutting units,
stop the engine and engage the parking brake.
2. Open control panel cover. Locate wire harness and
connectors near controller (Fig. 36). Carefully unplug
loop back connector from harness connector.
• The light is burned out.
29
blink on and off when corresponding switch is closed.
Repeat on each switch that is it possible to be changed
by hand.
7. If switch is closed and appropriate LED does not turn
on, check all wiring and connections to switch and/or
check switches with an ohm meter. Replace any
defective switches and repair any defective wiring.
The Diagnostic ACE also has the ability to detect which
output solenoids or relays are turned on. This is a quick
1
way to determine if a machine malfunction is electrical or
hydraulic.

the Diagnostic ACE, should be illuminated. If “outputs
displayed” LED is illuminated, press the toggle button,
on Diagnostic ACE, to change LED to “inputs
displayed”.
6. The Diagnostic ACE will illuminate the LED associated
with each of the inputs when that input switch is closed.
Individually, change each of the switches from open to
closed (i.e., sit on seat, engage traction pedal, etc.), and
note that the appropriate LED on Diagnostic ACE will
6. Sit on the seat and attempt to operate the desired
function of the machine. (If you need help verifying the
correct input settings for each function, refer to the
Logic Chart on page 32) The appropriate output LED’s
should illuminate to indicate that the ECU is turning on
that function. (Refer to the list on page 31, or the logic
chart to be certain of the specified output LED’s.
Note: If any output LED is blinking, this indicates an
electrical problem with that OUTPUT. Repair / replace
defective electrical parts immediately. To reset a blinking
LED, turn the key switch “OFF”, then back “ON”.
If no output LED’s are blinking, but the correct output
LED’s do not illuminate, verify that the required input
switches are in the necessary positions to allow that
function to occur. Verify correct switch function.
30
If the output LED’s are on as specified, but the machine
does not function properly, this indicates a non–electrical
problem. Repair as necessary.
Note: Due to electrical system constraints, the output
LED’s for “START”, “PREHEAT” and “ETR/ALT” may
not blink even though an electrical problem may exist for
those functions. If the machine problem appears to be with
one of these functions, be certain to check the electrical
circuit with a volt/ohm meter to verify that no electrical
problem exists to these functions.
If each output switch is in the correct position and
functioning correctly, but the output LED’s are not
correctly illuminated, this indicates an ECU problem. If this
occurs, contact your Toro Distributor for assistance.
Important The Diagnostic ACE display must not be
left connected to the machine. It is not designed to
withstand the environment of the machine’s every day use.
When done using Diagnostic ACE, disconnect it from the
machine and reconnect loopback connector to harness
connector. Machine will not operate without loopback
connector installed on harness. Store Diagnostic ACE in
dry, secure location in shop, not on machine.
Operating Characteristics
Familiarization
Before mowing grass, practice operating machine in an
open area. Start and stop the engine. Operate in forward
and reverse. Lower and raise cutting units and engage and
disengage reels. When you feel familiar with the machine,
practice operating up and down slopes at different speeds.
The brakes can be used to assist in turning the machine.
However, use them carefully, especially on soft or wet
grass conditions because the turf may be torn accidentally.
Individual turning brakes may also be used to help maintain
traction. For example, in some slope conditions, the uphill
wheel slips and loses traction. If this situation occurs,
depress uphill turn pedal gradually and intermittently until
the uphill wheel stops slipping, thus, increasing traction on
the downhill wheel.
Warning
When operating the machine, always use the seat
belt and ROPS together.
Hydraulic Valve Solenoid
Functions
Use the list below to identify and describe the different
functions of the solenoids in the hydraulic manifold. Each
solenoid must be energized to allow function to occur.

S1Front reel circuit
S2Rear reel circuit
S3Lift/lower front wing cutting units
S4Lift/lower center cutting unit
S5Lift/lower rear cutting unit
S6Lower any cutting units
S7Lift any cutting units
S8, S9Backlap any cutting units
Warning System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if the
machine is operated with a malfunction.
Mowing
Start engine and move throttle to FAST so engine is
running at maximum speed. Move the ENABLE/DISABLE
switch to ENABLE and use the LOWER MOW/RAISE
lever to control the cutting units (front cutting units are
timed to lower before the rear cutting units). To move
forward and cut grass, press traction pedal forward.
Transport
Move the ENABLE/DISABLE switch to joy stick
DISABLE and raise the cutting units to the transport
position. Be careful when driving between objects so you
do not accidentally damage the machine or cutting units.
Use extra care when operating machine on slopes. Drive
slowly and avoid sharp turns on slopes to prevent roll
overs. The cutting units should be lowered when going
downhill for steering control.
Important Allow engine to idle for 5 minutes before
shutting it off after a full load operation. Failure to do so
may lead to turbo–charger trouble.

General Air Cleaner
Servicing the Air Cleaner
Maintenance
• Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
• Service the air cleaner filter only when the service
indicator requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the
engine when the filter is removed
• Be sure the cover is seated correctly and seals with the
air cleaner body.
Servicing the Precleaner Bowl
Normally, inspect precleaner bowl daily. When conditions
are extremely dusty and dirty, inspect more frequently. Do
not let dust or debris build up above level marks on
precleaner bowl.
1. Remove thumb screw and separate cover from
precleaner bowl (Fig. 46).
2

1
1. Release the latches and remove the cover from the air
cleaner body (Fig. 46). Before removing the filter, use
low pressure air (40 psi, clean and dry) to help remove
large accumulations of debris packed between outside
of primary filter and the canister. Avoid using high
pressure air which could force dirt through the filter
into the intake tract. This cleaning process prevents
debris from migrating into the intake when the primary
filter is removed.

3. Assemble and install precleaner bowl, cover, and thumb
screw.
Note: When operating machine in extremely dusty
conditions, an optional extension tube (Toro Part No.
43-3810), which raises precleaner bowl above hood, thus,
lengthening the time between precleaner bowl servicing, is
available from your local authorized Toro Distributor.
3. Dust cup
2. Remove and replace the primary filter (Fig. 47).
Cleaning of the used element is not recommended due
to the possibility of damage to the filter media. Inspect
the new filter for shipping damage, checking the sealing
end of the filter and the body. Do not use a damaged
element. Insert the new filter by applying pressure to
the outer rim of the element to seat it in the canister. Do
not apply pressure to the flexible center of the filter.
3. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the cover,
clean the cavity and replace the outlet valve.
4. Install the cover orienting the rubber outlet valve in a
downward position – between approximately 5:00 to
7:00 when viewed from the end.
5. Secure the cover latches.

Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1/4 to 1/2 in. (6
to 13 mm) below the bottom of the filler neck.
This empty space in the tank allows the fuel to
expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.

Adjust the service brakes when there is more than 1 inch of
“free travel” of the brake pedal, or when the brakes do not
work effectively. Free travel is the distance the brake pedal
moves before braking resistance is felt.
1. Disengage locking pin from brake pedals so both pedals
work independently of each other.
2. To reduce free travel of brake pedals, tighten the brakes
by loosening the front nut on threaded end of brake
cable (Fig. 66). Then tighten rear nut to move cable
backward until brake pedals have 1/2 to 1 inch of free
travel. Tighten front nuts after brakes are adjusted
correctly.

Danger
Battery electrolyte contains sulfuric acid which is a
deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact with
skin, eyes or clothing. Wear safety glasses to
shield your eyes and rubber gloves to protect
your hands.
• Fill the battery where clean water is always
available for flushing the skin.
Warning
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks and
flames away from battery.
Note: Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery case
clean because a dirty battery will discharge slowly. To clean
the battery, wash the entire case with solution of baking
soda and water. Rinse with clear water. Coat the battery
