Before Use Checklist

Ensure that you carry out all procedures below before starting the engine or operating the equipment. All procedures described are generic in nature and slight variations between

different models may exist. Failure to follow the checklist and carry out the procedures correctly may

result in making the product warranty void. The product is NOT supplied with engine oil, although traces

of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the engine before use – see Engine Oil. Failure to add engine oil will void the product warranty.

Assembly

Typically, the lawn mower requires minimal assembly. Prior to assembly, unpack all components and check that all items have been received.

Handle

The handle comes assembled, however, must be attached to the lawn mower handle mounting brackets. Note that the following procedure is typical and that there may be slight differences between models; for example, on some machine the handle is attached using 2 screws and nuts per side.

1. Remove the handle attachment nuts and screws from the handle mounting brackets (C).

2. Pull the handle adjustment levers (D) out to unlock them and unfold the handle, then push the levers

back into the locked position. On some models that do not have adjustment, the top handle sections are attached directly to the lower sections using screws and nuts, similarly to the procedure below.

3. Ensure that any cables/wires are running along the top of the handle, then place the ends of the handle

in position with the mounting brackets (E) – for some models, the bottom hole in each leg of the handle goes over a spigot (F); for other models the handle is secured using 2 screws on each leg, with the handle mounted to the outer face of the brackets. Note that some models may have additional holes that can be used for changing the angle of the handle.

4. Insert the handle attachment screws (B) through the second hole in each handle leg from the inside,

then secure the handle with the handle attachment nuts (A). Firmly tighten (rotate right) the nuts.

5. Once the handle is secure, check that all cable/wires are

properly routed, without kinks etc, and are secured to the handle with any supplied clips.

6. If the machine is equipped with a "console" (G) that houses the

throttle control, drink holder etc, place it in position over the handle rails, and attach it using the supplied screws and curved washers (H).

Blades

Some machines feature "cross-cut" blades (four-blade design). If this is the case, pull them outward so they are straight – use caution as the cutting edge of the blade is sharp.

Engine Oil

The product is NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the

engine before use – see Engine Oil. Failure to add engine oil will void the product warranty. Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or

irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires regular maintenance. Check the engine oil level and ensure that the oil level is at or just under the maximum level indicator.

Always check the engine oil level before starting the engine. See Engine Oil.

Air Filter

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires regular maintenance.

Always check the air filter before starting the engine. See Air Filter.

Fuel

Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • The engine must be OFF and cool before refuelling.

Adequately fill the fuel tank with the correct fuel type.

• Use non-ethanol unleaded petrol (higher RON values will provide best engine performance). Do not use

old or contaminated fuel.

To fill or top up fuel:

1. Place the machine in an upright position on a flat and level surface.

2. Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap

is removed.

3. Remove (rotate left) the fuel filler cap.

4. Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or

otherwise overfill the tank.

5. When finished, re-install (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the

machine. If fuel has been spilt, move the machine away from the spillage before starting the engine.

Priming the Fuel System

For engines equipped with a fuel primer, it may be necessary to "prime" the fuel system before attempting to start the engine. This means removing any air from the fuel line and filling the carburettor with fuel. To prime:

1. Fill the fuel tank with fuel.

2. Locate the fuel primer (A).

3. Press the fuel primer repeatedly until you feel that fuel is in the primer.

4. Start the engine.

Spark Plug

The spark plug may come disconnected from the spark plug lead. If this is the case, place the electrical lead over the spark plug terminal and push it down so that it connects firmly with the terminal. See Spark Plug.

Engine Starting and Stopping

Before starting the engine, ensure that you have followed all procedures described in the

Before Use Checklist. The product is NOT supplied with engine oil, although traces of oil

from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the engine before use – see Engine Oil. Failure to add engine oil will void the product warranty.

Different models may feature variations in design; for example, some have different engine types etc. There are currently two major variations in how the engine speed is controlled:

• Manual – This is the more traditional style, using a throttle lever, where the position of

the lever determines the engine speed [just like the accelerator on a car]. Manual throttle engines generally have a choke setting on the throttle that is used for starting the engine when it is cold.

• Automatic – These engines have a

system that adjusts the throttle automatically based on the current engine load. For example, when the grass being cut is thick etc, the throttle opens up to maintain engine speed. Engines with an automatic throttle generally do not have a choke setting on the throttle, but rather just a "RUN" or "ON" position.

Major engine controls are identified on the machine by stickers or other markings. The following procedures and images are typical – the position or appearance of controls etc may vary.

Starting the Engine

1. PRIME – If necessary, "prime" the fuel system.

2. CHOKE – If the machine is equipped with a "CHOKE" or "COLD" or "COLD START" throttle setting, and

the engine is cold, place the throttle in that position. If the engine is warm or the ambient temperature is high, place the throttle somewhere in the "RUN" region [generally, just off the "STOP" position is good].

If the machine has no choke, place the throttle in the "START" or "RUN" position.

3. IGNITION – If the machine has an engine ON/OFF switch or key switch, place it in the "ON" ("I")

position. Note that some models may be wired so that "O" is the "ON" position. For key switches, the "OFF" position allows the key to be removed from the switch. The "ON" position is reached when the key is rotated from the "OFF" position.

4. START – Slowly pull out the starter cord (A) until you feel it engage with

the engine, then pull it out rapidly. The engine should start. Allow the starter cord to rewind slowly – do not let it "snap" back.

If the machine is equipped with electric start, press the "START" or "POWER" button or turn the key switch to the "start" position to use the electric start. Typically, electric start engines can also be pull started.

Note: If the machine features an "engine safety bar", it must be engaged in order to start the engine and for it to remain running. • Many models feature an extended length starter cord that hooks to the mower handle and allows the engine to be started from a normal standing position behind the mower.

5. WARM-UP and THROTTLE – It is good practice to allow the engine to warm-up and run smoothly

before using the machine. For manual throttles, set the desired engine speed once the engine is warm.

If the engine does not start, repeat step 4. If the engine fails to start after several attempts, refer to

Troubleshooting.

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

Stopping the Engine

• Place the throttle control in the "STOP" or "OFF" position, or, if equipped, release the engine safety bar.

• If equipped, place the engine ON/OFF switch or key switch in the "OFF" position.

Environmental Considerations

Altitude

If the engine is being used in altitudes at or above 1500m (approximately 5000’), adjustments to the carburettor may be required. This is because there is less oxygen in the air as altitude increases, which effectively "enriches" the ratio of fuel to air going into the engine and the higher the altitude, the richer the fuel mixture becomes. If the engine is being permanently operated at high altitude, it is recommended to have an authorized service centre make the necessary carburettor adjustments. If the engine is used occasionally at altitude (not extreme altitudes), no adjustments should be required, however, a slight decrease in engine performance can be expected.

Temperature

If the engine is being used in extremely cold or hot environments; for example, desert or snow conditions, the type of engine oil may need to be changed to suit environmental temperatures. Oil thickens as the temperature decreases and thins as temperature increases, which means that if the engine oil is not suited to the temperature its ability to properly lubricate the engine may be affected. Use the following chart to determine the correct engine oil:

Operation

Lawn mowers are high-speed, fast-cutting equipment with exposed blades that can cause serious or fatal injury if not used correctly or without taking proper safety precautions. It is

extremely important that you read and fully understand the information in this section and all other safety warnings / recommendations and usage instructions before using the equipment. • Always

wear suitable protective clothing and equipment when using the machine. • Inspect the machine before each use and check for wear or damage. If the machine is damaged, have it inspected and repaired at an authorized service centre before using it again. • If you experience excessive vibration from the mower during operation, this is an indication of wear or damage. It is recommended to have it inspected and repaired at an authorized service centre before using it again. • Be aware that once the engine is running,

the cutting blades will be rotating and parts of the machine may be extremely hot. • Ensure that the area to

be mowed is free of objects that may get caught in the mower or be thrown by it (stones, branches etc). When the engine is idling (slowest continuous running speed), the cutting action is minimal. As engine speed

increases, the cutting action becomes more efficient. Note the following recommendations:

• Operate the engine at a sufficient speed to provide the desired cutting action. This may vary on the type

of grass, grass height and density etc.

• After use, it is recommended to clean the mower of excessive grass cuttings, dirt etc. Some models

feature a "deck wash", which can be used to simplify cleaning the underside of the mower deck.

The lawn mower may have additional features to "just" cutting grass. For example, mulching, side discharge chute etc.

Using the Throttle

Once the engine is started, the machine can be used. For manual throttle machines, you adjust engine speed manually; for example, when cutting thicker or longer grass, increase engine speed. Push or pull the throttle within the range between the "START" and "STOP" positions to reach the required engine speed.

For machines that have automatic throttle control, just leave the throttle in the "START" position. When you are pushing the mower from one area to another, but not cutting, you can "idle" the engine [run it

slow, but not stop]. For manual throttle machines, place the throttle close to the "STOP" position. For automatic throttle machines, pull the throttle toward you approximately mid-way.

Engine Safety Bar

Some models may have an "engine safety bar" (A) [also known as a "brake bar" or "bail"] that must be engaged in order for the engine to start and run. When the bar is released, the engine automatically stops. This is a safety feature to help ensure that the mower operator is behind the mower while the engine is running.

To start and run the engine, hold the engine safety bar against the handle (B). Note the safety bar may be o either side of the handle.

Adjusting Cutting Height

Most lawn mowers feature adjustable cutting heights. The mechanism raises/lowers the lawn mower deck and has several steps. When setting cutting height, note that weeds can spread more easily in very short grass. If the grass is long it may be necessary to cut it in several passes, each time lowering the cutting height. To set the cutting height:

1. Pull the height adjustment lever (A) outward so that is disengages with the

teeth (B).

2. Rotate the lever forward to raise, or backward to lower, then release it at

the desired height.

Using the Grass Catcher

Note: Ensure that the mulching attachment (if equipped) is not installed when using the catcher.

When you want to catch the grass cuttings for disposal, use the grass catcher. The grass catcher hooks to the rear of the mower, under the rear guard. To attach and detach it:

1. Lift the bottom edge of the rear guard (A) sufficiently to allow the catcher to pass underneath it and hold

it in this position.

2. Insert the catcher (B), with open end toward the mower, and hook the catcher fingers (C) onto the

mounting points (D), then lower the rear guard so it rests on the top of the grass catcher.

To remove the grass catcher, lift the bottom edge of the rear guard, then lift the grass catcher to unhook it from the mower. Once unhooked, pull the grass catcher out and lower the rear guard.

Using the Mulching Attachment

Some models may feature a "mulching" attachment. Mulching is to re-circulate the cut the grass through the blades so that is very finely "chopped" and can be left on the cut grass as a "grass feed". When mulching, the grass catcher is not required. To install the mulching attachment:

1. Remove the grass catcher, if installed. Lift

up and hold the rear guard (A).

2. Insert the mulching attachment (B), with

the top angled forward slightly so that the protrusions on the bottom of the attachment enter the slots in the mower deck. Pull the top of the attachment back slightly so it is correctly fitted, then lower the rear guard.

To remove the mulching attachment, lift the rear guard, unhook the mulching attachment from the deck and pull it out, then lower the rear guard.

Using the Side Discharge Attachment

Some models may feature a "side discharge chute" attachment. The side discharge chute ejects the grass cutting to the side of the mower. When using the side discharge chute, the grass catcher is not required. To install the side discharge chute attachment:

1. Remove the grass catcher, if installed. Lift up and hold the flap (A) on the side of the mower deck.

2. Insert the side discharge chute attachment (B) under the flap. Ensure that the protrusions (C) on the

underside of the flap enter the slots (D) on the top of the side discharge chute, then lower the flap.

To remove the side discharge chute attachment, lift the flap until the chute unhooks from it, then remove the chute and lower the flap.

Using the Self-Propel Function

Some models may have a self-propelling function (forward direction only) to make mowing easier. The function is switched on and off using "drive activation bar" (A). When the bar is released, the drive stops. The speed of the drive is not directly controllable, however, may vary somewhat with engine speed.

Note: When the engine is not running, if the drive activation bar is pulled in, the drive gears will engage which can make it difficult to move the machine. It is recommended to release the drive activation bar when changing direction, reversing etc.

To activate the self-propel function, hold the drive activation bar against the handle (B). To deactivate the function, release the bar.

Using the Deck Wash Function

Some models may have a "deck wash" function to help make cleaning the blades and cutting area (under the deck) easier. Note that the function is not intended to completely clean the mower – it will remove some built-up cuttings and dirt from the deck, but more importantly, will soften it up to make removal by hand easier. Keeping the underside of the deck clean will prolong the life of the machine and blades. To use the deck wash function:

1. Install the mulching and side discharge chute attachments and lower

the deck to the lowest cutting height.

2. Attach a garden hose the deck wash port (A) and turn the water on.

3. Start the engine and allow it to run at high speed for approximately 30 to 60 seconds – be aware that

water and grass cuttings/dirt will be ejected through the side discharge chute.

4. Stop the engine and turn off the water, then scrape away cuttings/dirt from the deck by hand (wear

gloves) or using a suitable tool. This procedure may have to be repeated several times.

Mowing Guidelines

If the machine strikes against an object during mowing or an object gets caught in the

mower, stop the machine immediately. Allow the machine to stop running completely and to cool down before inspecting the machine and/or removing any objects that may be caught in it. If the machine is damaged, have it inspected and repaired at an authorized service centre before using it again. • If you experience excessive vibration from the mower during operation, this is an indication of wear or damage. It is recommended to have it inspected and repaired at an authorized service centre before using it again.

The following information are general guidelines to mowing:

• Avoid cutting wet grass. Wet grass clipping do not collect well and have a tendency to stick to the

underside of the mower deck.

• Avoid cutting very tall grass. If the grass is tall, mow in several passes, each time reducing the cut

height.

• Avoid overly steep slopes when mowing and, when mowing on an incline, mow across the face of the

incline, not up and down it.

• Be aware that cutting more than one third of the total height of the grass may affect the health of the

grass, and that weeds are able to spread more easily in extremely short grass. A healthier lawn is achieved by regular mowing and not cutting the grass back excessively.

• When mowing, move the mower through the grass at a sensible rate so as to not strain the machine or

otherwise reduce its effectiveness, and to achieve the best cutting results.

• Mow in slightly overlapping rows. An effective pattern is to mow in straight lines,

starting along the longest edge of the work area, then turning at the end and mowing the next row and so on. Using a regular pattern helps keep the end result neat and reduces the chance of uncut areas.

• For lawns with trees or flowerbeds, for best results it is recommended to cut 1 or 2

rows around the circumference of trees/flowerbeds.

• Regularly empty the grass catcher. Some models may feature an indicator to

show when the grass catcher requires emptying. This is usually a small flap on the top of the catcher that lifts when the catcher becomes full.

Engine Oil

Engines are NOT supplied with engine oil, although traces of oil from the manufacturing process may be present. It is essential to add adequate engine oil of the correct type to the

engine before use. Failure to add engine oil will void the product warranty. • Always check engine oil

level when the machine is in an upright position on a flat and level surface. • Do not use used or

contaminated engine oils. • Use only engine oils of the correct type (see Specifications). • Perform the first oil

change within the first 20 hours of use. Subsequently, change the oil every 20 hours of use. • It is

recommended that the engine be warm, but not hot, when performing oil changes. When the oil is warm it

drains faster. • Using dirty or incorrect engine oil may cause engine damage and void any warranty • Always use suitable tools. • Always dispose of used oil in an environmentally responsible manner and according to

regulations. • Some engines feature oil level detection, which will prevent the engine being started or automatically stop a running engine if there is insufficient oil. • Always check the oil level and ensure is at or near the "MAX" indicator before using the machine. • Some models may have 2 oil drain plugs and

fillers on either side of the engine – it does not matter which one is used. 4-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or

irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires regular maintenance as per the maintenance schedule.

To check engine oil level:

1. Place the machine on a flat and level surface.

2. Clean the machine around the oil filler cap (A) so that no dirt or other material enters the engine when

the cap is removed.

3. Remove the oil filler cap (rotate left) until fully unscrewed. For machines without a dipstick, the oil level is

determined by how close the oil is to the edge of the filler hole (B). For machines equipped with an oil level dipstick:

a. Remove the dipstick (C) and wipe clean with a piece of cloth or paper. b. Insert the dipstick into the oil filler but do not screw it in. c. Remove and inspect the dipstick – the oil level is determined by where oil can be seen on it.

4. Ensure that the oil level is at or just under the "maximum". If the oil level is low, add additional oil until the

correct level is reached. If the oil level is too high, drain some oil until the correct level is reached.

5. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the

machine.

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

To change the engine oil: Note: Briggs & Stratton "EXi" type engines do not require regular oil changes.

1. Place the machine on a suitable work surface that is flat and level and have a container ready to catch

drained oil.

2. Clean the machine around the oil drain plug (D) and oil filler cap/dipstick so that no dirt or other material

enters the engine when the plug or cap is removed.

3. Unscrew (rotate left) and remove the drain plug and washer.

4. Tilt the machine and drain all oil from the engine. Once drained, allow the machine to sit level again.

5. Clean the drain plug and washer and then reinstall them. Screw in fully (rotate right) and firmly tighten.

6. Remove the oil filler cap (rotate left) until fully unscrewed. Wipe the oil level indicator clean with a piece

of cloth or paper.

7. Using a funnel, carefully add oil to the engine until the "maximum" level is reached. Double-check the oil

level (described above).

8. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the

machine.

Air Filter

Operating the machine without a functional air filter may cause severe engine damage and will void

any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken as fuel system problems. Check the condition of the air filter before adjusting engine idle speed, where applicable. • If the air filter is damaged (torn, broken, disintegrating), replace it.

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal damage to it. The air filter requires regular maintenance as per the maintenance schedule.

Inspection and Cleaning

Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as necessary. To clean air filters:

• For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.

• For paper filters, use compressed air to blow particles from it. The air should be blown from the engine

side of the filter. Tapping the filter element against a hard surface and brushing the pleats using a soft brush may also help remove debris from the filter.

• Clean all other air filter assembly components using water and mild detergent, then dry them.

• For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to spread

the oil through the filter material and remove any excess oil.

Removal/Installation

1. Depending on model, the air filter cover (A) may be secured using a screw (B), or clips (C) into position.

If the cover has a screw, loosen it (rotate left) and remove the cover from the air intake assembly. If the air filter cover is secured with clips, carefully release them – usually, you will need to press the tab of the clip to release it. Carefully remove the air filter cover – some covers may hinge or have protrusions that help locate it against the engine.

2. Remove the filter element (D).

To install the air filter:

1. Insert the air filter element, and ensure it is correctly positioned in relation to the air intake assembly as it

will seat and seal properly in one position only.

2. Re-install the filter cover, ensuring it is fitted properly against the engine and secure it with the screw

(rotate right and tighten by hand. Do not over-tighten), or clips.

Spark Plug

If the spark plug is damaged (cracked insulator, broken or eroded electrodes etc), replace it. •

Always use spark plugs of the correct "heat range" - see Specifications. The spark plug is used to ignite the air/fuel mixture inside the engine. The spark plug has electrodes on one

end and an electrical terminal on the other. The spark plug requires regular maintenance.

Cleaning and Gap Checking

The spark plug should be checked and cleaned as per the maintenance schedule.

1. Remove any carbon deposits on the spark plug (A) electrodes (B) with a wire

brush.

2. Clean the spark plug threads and the electrical terminal (C) on the top. To check and adjust the spark plug "gap":

1. Use "feeler" or "thickness" gauges (X) to measure the existing gap. The gauge

must drag a little when being slid between the electrodes (2) – this means the measurement is fairly accurate.

2. Adjust the gap to within specification (see Specifications). If the gap needs to be

reduced, gently tap the electrode as required. If the gap needs to be increased, use pliers to gently pull the electrode as required.

3. Measure the gap again and ensure it is within the specified range before re-installing the spark plug.

Removal/Installation

1. Pull the electrical lead (A) from the terminal on top of the spark plug (B).

2. If accessible, clean the area around the spark plug so that no dirt or other material can enter the engine

when the spark plug is removed.

3. Use the spark plug tool (C) to remove the spark plug (rotate left).

To re-install the spark plug:

1. Place the spark plug in its hole and screw it in (rotate right) until "finger tight".

2. Use the spark plug tool to tighten the spark plug approximately one quarter turn (do not over-tighten).

3. Place the electrical lead over the spark plug terminal and push it down so that it connects firmly with the

terminal.

Cleaning Guidelines

Do not use solvents, chemicals or abrasives when cleaning the machine, as some surfaces may be

damaged. • Wear gloves or use suitable tools to assist in cleaning – do not use bare hands. • Clean the machine after every use to ensure best performance and longest service life. • It is recommended to jack the machine up when inspecting or working on the underside of the deck. Avoid tilting the machine to avoid potential fuel or oil spills or leaks.

• Use a slightly damp cloth, water and mild detergent for cleaning.

• Use a brush for parts that are difficult to reach.

• Ensure air vents and surfaces designed for heat dissipation are clean and free of obstructions or debris.

• Remove clippings, dirt etc from the underside of the deck and cutting blades (the deck wash function on

some models assists this procedure).

• It is recommended to lightly oil the cutting blades after each use to help prevent corrosion.

• Ensure all chutes and flaps are clean and not obstructed.

• Ensure that spring-loaded parts, such as the rear guard, return to the normal position when released.

• Clean and check the grass catcher for any damage – replace damaged parts. Allow the grass catcher to

dry thoroughly before storing to prevent mildew or deterioration of the catcher netting (where applicable).

• Ensure that all control cables, levers, switches etc are clean and operate normally and smoothly.

Transportation and Storage

Always ensure that the machine is cool enough to touch before transporting or

storing. • Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other ignition sources. • Always transport the machine with the fuel tap and engine ON / OFF switch (where applicable) in the "OFF" position. • Drain the fuel tank before transportation or storage.

Preparing for Transport and Storage

• Drain the fuel system by allowing the engine to run until it stops.

• Ensure that the fuel tap (if applicable), engine ON/OFF or key switch (where applicable) is in the "OFF"

position.

• Disconnect the spark plug lead.

• Avoid exposing the equipment to direct sunlight, particularly during transportation.

• Ensure the equipment is secure and upright during transport.

• Store the unit in a dry, well-ventilated area and out of the reach of children.

Long Term Storage

Follow the normal procedures for storage, then:

• Drain the fuel system. It is advised to have the fuel tank as empty as possible before draining.

a. Unscrew (rotate left) the carburettor drain plug. Use a suitable container to catch the draining fuel,

and allow the fuel to drain. Store the drained fuel in a properly sealed container.

b. Re-install (rotate right) the carburettor drain plug and tighten.

• Remove the spark plug and put 10ml of clean engine oil into the cylinder. Pull the starter cord slowly to

distribute the oil. Re-install the spark plug.

• Cover the equipment to protect it.
