SAFETY PRACTICES FOR WALK-BEHIND MOWERS

This lawn mower is capable of amputating hands and feet

and throwing objects. Failure to observe the following safety

instructions could result in serious injury or death.

I. GENERAL OPERATION

1. Read, understand, and follow all instructions on the

machine and in the manuals before starting.

2. Do not put hands or feet near or under the machine. Keep

clear of the discharge opening at all times.

3. Only allow responsible adults, who are familiar with these

instructions, to operate this machine.

4. Clear the area of objects such as rocks, wire, toys, etc.,

LAWN MOWER SAFETY

II SLOPE OPERATION

Slopes are a major factor related to slip and fall accidents,

which can result in severe injury. Operation on all slopes

requires extra caution. If you feel uneasy on a slope, do not

mow it.

1. Mow across the face of slopes; never up and down. Exer-

cise extreme caution when changing direction on slopes.

2. Watch for holes, ruts, bumps, rocks, or other hidden ob-

jects. Uneven terrain could cause a slip and fall accident. Tall

grass can hide obstacles.

3. Do not mow on wet grass or excessively steep slopes.

Poor footing could cause a slip and fall accident.

4. Do not mow near drop-offs, ditches, or embankments. You

could lose your footing or balance.

III. CHILDREN

Tragic accidents can occur if the operator is not alert to the

presence of children. Children are often attracted to the ma-

chine and the mowing activity. Never assume that children will

remain where you last saw them.

1. Keep children out of the mowing area and under the watch-

ful care of a responsible adult other than the operator.

2. Be alert and turn mower off if a child enters the area.

3. Never allow children to operate the machine.

4. Use extra care when approaching blind corners, shrubs,

trees, or other objects that may block your view of a child.

IV. SAFE HANDLING OF GASOLINE:

To avoid personal injury or property damage, use extreme care

in handling gasoline. Gasoline is extremely ﬂammable and the

vapors are explosive.

1. Extinguish all cigarettes, cigars, pipes, and other sources of

ignition.

2. Use only an approved gasoline container.

3. Never remove gas cap or add fuel with the engine running.

Allow engine to cool before refueling.

4. Never refuel the machine indoors.

5. Never store the machine or fuel container where there is an

open ﬂame, spark, or pilot light such as on a water heater or

on other appliances.

6. Never ﬁll containers inside a vehicle or on a truck or trailer

bed with a plastic liner. Always place containers on the ground

away from your vehicle before ﬁlling.

7. Remove the mower from the truck or trailer and refuel it on

the ground. If this is not possible, then refuel the mower with

a portable container, rather than from a gasoline dispenser

nozzle.

Continued,

8. Keep the nozzle in contact with the rim of the fuel tank or

container opening at all times until fueling is complete. Do not

use a nozzle lock-open device.

9. If fuel is spilled on clothing, change clothing immediately.

10. Never overﬁll fuel tank. Replace gas cap and tighten

securely.

V. GENERAL SERVICE

1. Never operate the mower in a closed area.

2. Keep all nuts and bolts tight to be sure the mower is in safe

working condition.

3. Never tamper with safety devices. Check their proper

operation before each use of the mower.

4. Keep the mower free of grass, leaves, or other debris build-

up. Clean up oil or fuel spillage and remove any fuel-soaked

debris. Allow machine to cool before storing.

5. If you strike a foreign object, stop and inspect the mower.

Repair, if necessary, before starting.

6. Never make any adjustments or repairs with the engine

running. Disconnect the spark plug wire and ground against

engine to prevent unintended starting.

7. Never attempt to make wheel height adjustments while the

engine is running.

8. Check grass catcher components and the rear discharge

door frequently and replace only with Ybravo.com original

parts when necessary.

9. Mower blades are sharp. Wrap the blade or wear gloves,

and use extra caution when servicing them.

10 Do not change engine governor setting or over speed the

engine.

11. Maintain or replace all safety and instruction labels.

CAUTION

Mufﬂer and other engine parts become extremely

hot during operation and remain hot after engine

has stopped. To avoid severe burns on contact,

stay away from these areas.

DECALS AND LOCATIONS

These labels warn you of potential hazards that can cause serious injury. Carefully read and understand them.

If a label comes off or becomes hard to read, contact Ybravo.com immediately for a free replacement.

CONTROLS & OPERATION

Before operating the mower for the ﬁrst time, please review

and understand the entire manual including all Warnings and

Cautions.

Even if you have operated other mowers in the past please

take time to become familiar with how this mower works and

practice all operations to build up your skills.

BEFORE ANY OPERATION ALWAYS:

- Inspect the mower for any visible damage or broken parts

- Check the oil level in the engine

-Make sure that when you release the upper control bar

that the blade will disengage and stop. If it does not stop

immediately do not use the lawn mower until the problem has

been corrected. Contact Ybravo.com for advice.

- Never operate the mower with obvious damage or

malfunction until the problems have been corrected.

WARNING

Never make any adjustments or repairs with the

engine running. Disconnect the spark plug wire,

and keep the wire away from the spark plug to

prevent accidental starting.

STARTING THE ENGINE

To start a cold engine it is important to use the “Choke”

position. To start a warm engine it is not necessary to use the

choke.

For best performance use the “Full Throttle” position for all

mowing. To verify that the engine is running at full throttle

please follow the steps outlined under the set up instructions

- Step 7 on Page 8 or 9.

AYbravo.com dealer can typically also verify the correct full

throttle adjustment. The engine speed should be approximate-

ly 3600 RPM without the blade engaged (no load).

BLADE CONTROL - BBC (Blade Brake Clutch)

It is a multi step process to engage the blade. Do not start the

engine and the blade on an uncut lawn. If the blade is blocked

by tall grass or debris it can damage the belt drive between the

engine and the blade during the engagement.

1. Start the engine and let it warm up for 10 to 30 seconds.

2. Set the throttle control to the “Full Throttle” position.

3. Push the lock (1) for the upper control bar to the side.

4. Push down on the upper control bar until it rests on the

handlebar (2). You will distinctly hear the blade operating -

making a fan like noise.

5. When the upper control bar is released the blade should

stop within 3 seconds.

Additional maintenance instructions are found on Page 14.

WARNING

NEVER insert a hand or any other object in the grass

discharge chute to verify that the blade has stopped.

If the blade continues to run (no change in the noise

or size of the grass bag) after releasing the upper

control bar it is an indication of a malfunction of the

BBC system.

If the blade did not stop during the BBC Function Test

procedure or if you are unsure - Immediately stop the

engine by using the throttle control on the left side of

the control panel. The BBC system will require a repair

before further use. Immediately contact Ybravo.com

for advice. Do not under any circumstances defeat the

function of the BBC system. This can cause serious

injury or death.

CHOKE

FULL THROTTLE

IDLE THROTTLE STOP

BBC Function Test - Before each use

A simple test to verify the BBC function is to install an empty

grass collection bag. The mulch plug should not be installed.

1. Start the engine.

2. Engage the blade per above procedure. Notice how the

noise changes and that the bag becomes “inﬂated”.

3. Release the upper control bar. If the bag does not “deﬂate”

immediately, it indicates that the blade is still engaged and

rotating.

4. IF the bag deﬂated - verify that the blade has stopped

rotating by removing the grass bag and look at the stopped

blade through the grass discharge chute.

CONTROLS & OPERATION

Drive Adjustment

When operating the lower control

bar (1) typical movement on the

red adjustment knob (3) should be

between 1/4” to 3/8” (6 to 10 mm)

DRIVE CONTROL

The drive system consists of a two speed transmission and an

adjustable belt drive from the engine to the transmission.

The transmission speed can be set to LO - N - HI.

HI speed is approximately 4mph - a fast walking speed.

LO speed is approximately 3mph - an average walking speed.

The shifter arm is intentionally made ﬂexible. When the arm is

locked in the LO or the HI position the transmission will

automatically mesh into the gears as soon as the drive is

engaged by operating the lower control bar.

ENGAGING THE DRIVE

To engage and disengage the drive system pull up on the

lower control bar (1). Typically the drive will engage when the

lower control bar is approximately 1 to 1.5 inches from the

handle (2).

Notice

Due to wear, the drive engagement position of the lower

control bar can change. If the distance between the lower

bar and the handle (2) is less than a 1/4 inch when the mower

starts to drive make an adjustment on the red knob located

below the engine fuel tank (3).

If needed turn the red knob 2 turns clockwise. Verify the drive

position of the control bar by operating the mower. If needed

repeat the adjustment.

HEIGHT ADJUSTMENT

Each wheel can be adjusted individually to a speciﬁc cutting

height from 1 inch to 4.5 inch. Notice: It is only possible to

move the adjustment on one side 2 - 3 steps each time.

Moving the front wheel height adjusters forward raises the

cutting height. Moving the rear wheel height adjusters towards

the rear of the mower raises the rear cutting height.

Always adjust the height adjusters to the same position both in

the front and the rear for best cutting results.

WARNING

Never readjust the cutting height while the engine

is running. STOP the engine. Never lift the

mower by placing your hand or ﬁngers under the

edge of the mower deck.

MODES OF OPERATION

This mower is approved to be used in two different operational

modes:

1 With a grass catcher in place

An original equipment Ybravo.com catcher has been tested to

be used with this mower. It is important to always inspect the

catcher for deterioration. If the material is ripped or worn the

bag shall not be used.

2. With the mulch plug installed

If the mulch plug is installed ensure that the rear door can

close completely.

WARNING

Do not operate the lawn mower without the mulch

plug or the Ybravo.com grass catcher in place.

Never attempt to operate the mower with the rear

door removed, damaged or propped open.

This maintenance schedule assumes daily use by a landscape company.

One Month of use is assumed to be 15 to 20 days of operation.

Maintenance -

Service Interval Procedures

Before each use Check the engine oil level.

Check the operation and integrity of the BBC control system (see page 10).

Inspect the mower blade for wear or damage.

Inspect the cables for any wear or damage.

Inspect the grass catcher for any damage.

Check for any loose or missing screws or damaged parts.

Clean under the lawn mower deck (after usage).

First 20 Hours or

Within 4 weeks Change the engine oil (see page 13).

Check the throttle cable adjustment (see pages 8-9).

Every 50 Hours or

every 2 months Lubricate the pivot arms on the control panel with oil.

Check the function and adjustment of the Blade Brake Clutch cable (see page 14)

Check and clean the engine air ﬁlter (see the engine Owner’s Manual)

Every 100 Hours or

every 4 months Change the engine oil (more often in dusty conditions).

Check the spark plug.

Clean the engine with compressed air.

Every 200 Hours or

every 8 months Replace the paper air ﬁlter (more frequently in dusty conditions).

Replace the spark plug.

Adjust the valve clearance.

NOTICE

Several of the operations described in this

Maintenance section involves placing the mower

on its right side.

To avoid spills of oil and gasoline always:

- Place the mower on a hard surface such as a

concrete driveway or a garage ﬂoor.

- Never place the mower on its side when there is

gasoline in the tank - do the service of the mower

when you have run out of gasoline during normal

operation.

- Always make sure that the Oil Filler Cap is

tightened.

Any spillage of oil or gasoline can be extremely

ﬂammable and explosive and under certain

conditions can cause serious personal injury and

property damage.

CLEANING THE MOWER

We do not recommend using a garden hose to clean the

mower. The buildup of moist grass, fertilizer and water can

cause extreme corrosion damage to many parts of the mower

and the engine.

Never use a Pressure Washer:

The use of a pressure washer can force water and moisture

into ball bearings and engine parts and cause substantial dam-

age.

- Clean the underside of the mower by scraping any build-up

of grass and trash.

- Clean off the outside of the engine and the top of the mower

with compressed air. Any accumulation of debris under the

belt cover can typically also be removed with compressed air

without removing the protective belt cover.

- Wash the Grass Bag with a garden hose frequently. The

holes that allows the grass bag to breathe will eventually clog

with dirt. A clogged bag will not collect the grass clippings

effectively. Do not install and use a wet grass catcher. It will

plug prematurely.

BLADE MAINTENANCE

For best results, the mower blade must be kept sharp. Always

replace a bent or damaged blade.

Removing the blade

1. Disconnect spark plug wire from spark plug and place wire

where it cannot come in contact with plug.

2. Turn lawn mower on its right side. (Make sure air ﬁlter and

carburetor are up).

3. Use a wood block between blade and mower deck to

prevent blade from turning when removing blade bolts.

NOTE: Protect your hands with gloves and/or wrap the blade

with a heavy cloth.

4. Remove blade bolts by turning counter-clockwise with a

11/16” (17mm) wrench or socket.

Installing the blade

1. Position the blade with the bent corner of the blade (sail)

pointing towards the deck. Install the blade bolts.

Important: Blade bolts are heat treated. If a bolt is worn or

damaged replace it only with a bolt available from Ybravo.com.

2. Use a block of wood between blade and mower deck and

tighten the blade bolts. Always use a torque wrench.

The recommended tightening torque is 30 to 35 ft. lbs.

(40 to 45 Nm)

WARNING

Use only a replacement blade approved by

Ybravo.com. Using a blade not approved by

Ybravo.com is hazardous. It can damage your

mower and cause serious personal injury.

A worn or damaged blade can break and parts of

the blade could be thrown into the operators or

bystanders area, resulting in serious personal

injury or death.

Inspecting the blade

Carefully examine the blade for straightness, damage and

abnormal wear. In some areas abrasive sand and dust can

wear away the metal of the blade - see illustration.

Sharpening the blade

File the top side of the blade (1) and maintain the original

angle of the cutting edge. Maintain the radius where the cut-

ting edge ends. Always remove the same amount of material

from both ends of the blade. This ensures that the blade stays

balanced.

If sharpening is done with a grinding stone the blade should
