RYOBI RLM36X46HPG Battery Lawn Mower Instruction Manual

Important! It is essential that you read the instructions in this manual before assembling, maintaining and operating the product.

Subject to technical modification

Safety, performance, and dependability have been given top priority in the design of your cordless lawnmower.


The cordless lawnmower is intended for outdoor use only.
The product is designed for domestic lawn mowing. It is a pedestrian-controlled walk behind lawnmower designed to be pushed by hand or used with the power assist feature.
The product should never be operated with the wheels off the ground. It should not be pulled or ridden on.
Do not use the product for any other purpose.


  • Keep the instructions safe for later use.
  • The product should be operated only with the battery packs specified in this manual. When using a battery-operated product, basic safety precautions should always be followed to reduce the risk of fire, leaking batteries, and personal injury.


  • Never allow children or people with reduced physical, sensory, or mental capabilities, or persons who are not familiar with these instructions to operate, clean, or maintain the product. Local regulations may restrict the age of the operator. Children should be adequately supervised to ensure that they do not play with the product.
  • Be familiar with the controls and the correct use of the product.
  • Wear heavy, long trousers, long sleeves, and sturdy anti-slip footwear. Do not wear short trousers, sandals, or go barefoot. Avoid wearing clothing that is loose-fitting or that has hanging cords or ties.
  • Use the product across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes. Keep firm footing and balance. Walk; never run.
  • Do not use the product near drop-offs, ditches, excessively steep slopes, or embankments.
  • Always wear safety glasses.
  • The product is capable of amputating hands and feet, and of throwing objects. Failure to observe all safety instructions could result in serious injury or death.
  • Stay alert, watch what you are doing, and use common sense when operating the product. Do not operate the product while tired, ill, or under the influence of drugs, alcohol, or medication. A lapse in concentration while operating the product may result in serious personal injury.


  • Never use the product while people, especially children, or pets are within 15 m because of the danger of objects being thrown by contact with the blade.
  • Always use the product in daylight or good artificial light.
  • Do not operate the product on wet grass or in the rain.
  • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.
  • Objects struck by the lawnmower blade can cause severe injuries to persons. Thoroughly inspect the area where the product is to be used, and remove all rocks, sticks, metal, wire, bones, toys, or other foreign objects. Remember, string or wire may entangle with the cutting means.
  • Do not operate the product in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. The product creates sparks, which may ignite dust or fumes.
  • Do not use the product when there is a risk  of lightning.
  • Tragic accidents can occur if the operator  is not alert to the presence of children.  Children are often attracted to the product and the mowing activity. Never assume that children will remain where you last saw them.
  • Use extra care when approaching blind corners, shrubs, trees, or other objects, including overhanging shrubs, which may block your view.


  • Read, understand, and always follow the safety instructions which came with your battery and charger. Failure to do so may result in electric shock, fire or other hazardous situations. Keep all the instructions together in a safe place for future reference.
  • Battery-operated products do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Remove the isolator key whenever you are not operating the product.
  • Remove the battery pack before making any adjustments, cleaning, or removing material from the product.
  • Ensure the isolator key is removed before inserting battery pack.
  • A battery pack must be recharged only with the charger specified by the manufacturer. Using a charger with an incompatible battery pack may create a risk of fire. Use battery pack only with charger listed.
  • Use only battery pack intended specifically for the product. Use of any other battery packs may result in a risk of fire, electric shock, or injury to persons.
  • When battery pack is not in use, keep it away from other metal objects like, paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery pack terminals together may cause sparks, burns, fire or explosion.
  • Do not place battery products or their batteries near fire or heat. This increases the risk of explosion and possibly injury.
  • Do not open or mutilate the battery pack. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
  • Protect the battery pack against moisture and water. Do not charge the product in a damp or wet location. Following this rule will reduce the risk of electric shock.
  • In case of damage and improper use of the battery, vapour may be emitted. Provide for fresh air and seek medical help in case of complaints. The vapour can irritate the respiratory system.
  • Do not leave the battery pack inside a vehicle in hot or cold conditions.
  • Do not incinerate the battery.
  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.


  • Before use, always visually inspect the product to ensure that blades, blade bolts, and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.
  • Bring the product to an authorised service centre to replace damaged or unreadable labels.
  • Do not pull the product backwards unless absolutely necessary. If you must back the product away from a wall or obstruction, first look down and behind to avoid tripping or pulling the product over your feet.
  • Turn off the product and allow the blade to stop if the product has to be tilted for transportation when crossing surfaces other than grass, and when transporting the product to and from the work area.
  • Never use the product with defective guards or shields, or without safety devices, such as deflectors and grass catchers, in place.
  • Do not tilt the product when turning on the motor or while the motor is running. If absolutely necessary, you may raise the front of the lawnmower by no more than 5 cm to enable easier starting. Press down on the handlebar to achieve this. Always return the lawnmower to its normal position with all wheels on the ground before cutting. Tilting the lawnmower exposes the blade and increases the probability of objects being thrown and accidentally making contact with the blade.
  • Do not start the product when standing in front of the grass discharge opening.
  • The product must be started with the user behind the handlebars in the operator safety zone. Never start the product if:
    • The grass discharge chute is exposed and is not protected by the grass catcher and grass discharge chute cover.
    • Hands and feet of all persons are not clear of the cutting enclosure.
  • Turn on the product carefully according to instructions, and keep hands and feet away from the blades. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.
  • Never pick up or carry the product while it is running.
  • Turn off the product, and remove the isolator key and the battery pack. Make sure that all moving parts have come to a complete stop:
    • whenever leaving the product unattended (including disposal of grass clippings)
    • before clearing blockages or unclogging the discharge chute before checking, cleaning, or working on the product
    • before removing the grass catcher or opening the grass discharge chute cover
    • after striking a foreign object; inspect the product for damage and make repairs as necessary before restarting and operating the product
    • if the product starts to vibrate abnormally (check immediately) ­
      – inspect for damage, particularly the blades
      -­ replace or repair any damaged parts ­ check for and tighten any loose parts
  • The cutting blade should rotate approximately parallel to the ground over which it is being wheeled.
  • The blade on the product is sharp. Use extreme caution, and wear heavy-duty gloves when fitting, replacing, cleaning, or checking bolt security.
  • Never operate the product if the on/off switch on the handlebar does not properly start and stop the product.
  • Never attempt to lock the on/off switches in the on position; this is extremely dangerous.
  • Do not force the product. It will do the job better and safer at the speed for which it was designed.
  • Stop the blade when crossing gravel surfaces.
  • Avoid holes, ruts, bumps, rocks, property stakes, or other hidden objects. Uneven terrain could cause a slip-and-fall accident.
  • Always ensure that the motor control cable is never trapped, pinched, or otherwise damaged during assembly or when folding the handle.
  • Injuries may be caused, or aggravated, by prolonged use of the product. When using the product for prolonged periods, ensure to take regular breaks.


  • To reduce the risk of fire, personal injury, and product damage due to a short circuit, never immerse the tool, battery pack, or charger in fluid or allow fluid to flow inside them. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, and bleach or bleach-containing products, etc., can cause a short circuit.
  • Do not dispose of battery packs together with household waste material. They must be collected separately and returned to an environmentally compatible recycling facility. Check with your local authority or retailer for recycling advice and collection point.



The product has an overload protection device. When overloading is detected, the product automatically turns off. If the overload protector  is actuated, the on/off lever must be released. SV Press the start button, and squeeze the on/off FI lever to restart the product. If the product still  does not start, reinstall the battery pack.

The battery pack has overheat protection. Excessive temperatures will cause the battery to stop powering the product. If the battery pack is too warm, allow it to cool down before resuming operation. If the product still does not work, recharge the battery.

NOTE: The battery pack LED indicator will not work if the battery protection feature has caused the battery pack to stop powering the product. Turn off the product or remove the battery pack from the product, and the battery pack LED indicator will resume normal function.


The mulching plug covers the rear discharge opening, which allows the blade to cut and recut for finer clippings.


The grass catcher collects grass clippings and prevents them from being discharged across the lawn


The product is equipped with a power assist lever that activates the self-propel function. Pressing the power assist lever down drives the product forward without having the user push it.
NOTE: The power assist feature functions normally when the product is used on a flat surface. The user needs to push the product forward when using the product on slopes or uneven surfaces because the power assist function will be limited and may cause the wheel to slip.


The run time of the battery depends on the condition, length, and density of the grass.
Adjust the cutting height of the lawnmower to suit the current condition of the lawn.

  • For best performance, always cut off one third or less of the total height of the grass.
  • When cutting long grass, reduce walking speed to allow for more effective cutting and a proper discharge of the clippings.
  • A higher cutting height extends the run time of the battery pack.


  • Turn off the product, and remove the isolator key and the battery pack. Make sure that all moving parts have come to a complete stop. Allow the product to cool down before storing or transporting.
  • Remove all foreign materials from the product. Store the product in a cool, dry, and well-ventilated place that is inaccessible to children. Keep the product away from corrosive agents such as garden chemicals and de-icing salts. Do not store the product outdoors.
  • For transportation in vehicles, remove the isolator key, and secure the product against movement or falling to prevent injury to persons or damage to the product.
  • Use extreme caution when lifting or tilting the product for maintenance, cleaning, storage, or transportation. The blade is sharp. Keep all body parts away from the blade while it is exposed.


Transport the battery in accordance with local and national provisions and regulations.
Follow all special requirements on packaging and labelling when transporting batteries by a third party. Ensure that no batteries can come in contact with other batteries or conductive materials while in transport by protecting exposed connectors with insulating, nonconductive caps or tape. Do not transport batteries that are cracked or leaking. Check with the forwarding company for further advice.


  • Use only original manufacturer’s replacement parts, accessories, and attachments. Failure to do so can cause possible injury, can contribute to poor performance, and may void your warranty.
  • Servicing requires extreme care and knowledge and should be performed only by a qualified service technician. Have the product serviced by an authorised service centre only.
  • Turn off the product, and remove the isolator key and the battery pack. Make sure that all moving parts have come to a complete stop before any cleaning or maintenance task.
  • Replace worn or damaged parts for safety.
  • Frequently check the grass catcher for wear or deterioration.
  • Check all nuts, bolts, and screws at frequent intervals for proper tightness to ensure that the product is in safe working condition.
  • Be careful during adjustment of the product to prevent entrapment of the fingers between moving blades and fixed parts of the product.
  • When servicing the blades, be aware that even though the power source is turned off, the blades can still be moved.
  • You may make adjustments and repairs described in this manual. For other repairs, have the product serviced by an authorised service centre only.
  • After each use, clean the plastic parts with a soft, dry cloth. Any part that is damaged should be properly repaired or replaced by an authorised service centre.
  • The blade on the product is sharp. Use extreme caution, and wear heavy-duty gloves when fitting, replacing, cleaning, or checking bolt security.
  • The blade bolts must be adequately tightened. See the manufacturer’s recommendations for blade bolt torque, which can be found in the product specification table in this manual.


  • Turn off the product, and remove the isolator key and the battery pack. Make sure that all moving parts have come to a complete stop.
  • Always wear heavy-duty gloves when checking or clearing a blockage. The blades are sharp, and the blockage itself could be a sharp object.
  • Remove the grass catcher. Check and carefully clear the grass catcher for obstructions.
  • Check the grass discharge chute, and carefully clear blockages.
  • Turn the product on its side. Check its underside and the area around the blade. Carefully remove any blockages. Remember that the blade may move during cleaning.

The declared vibration total values and the declared noise emission values given in this instruction manual have been measured in accordance with a standardised test and
may be used to compare one tool with another. They may be used for a preliminary assessment of exposure.

The declared vibration and noise emission values represent the main applications of the tool. However, if the tool is used for different applications, used with different accessories, or poorly maintained, the vibration and noise emission may differ. These
conditions may significantly increase the exposure levels over the total working period. An estimation of the level of exposure to vibration and noise should take into account the times when the tool is turned off or when it is running idle. These conditions may
significantly reduce the exposure level over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration and noise, such as maintaining the tool and the accessories, keeping the hands warm (in case of vibration), and organising work patterns.
