Frequently Asked Questions - RLM50 G-TECHNOLOGY

How do I adjust the cutting height on my RLM50 mower?

Use the central lever located on the top of the mower deck. There are 6 positions ranging from 25 mm to 75 mm. Turn the lever to the desired setting for optimal grass length.

What type of grass bag does the RLM50 use?

The RLM50 uses a 60-liter fabric grass bag with a plastic handle. Ensure the bag is properly attached to the rear discharge chute before mowing.

How often should I sharpen the blade?

For best performance, sharpen the blade at least once per season or after every 25 hours of use. A dull blade tears grass instead of cutting it cleanly.

Can I use an extension cord with the electric mower?

Yes, use a heavy-duty outdoor extension cord rated for at least 15 amps. Ensure the cord is fully unwound to prevent overheating and keep it away from the cutting path.

What should I do if the mower won't start?

First, check that the power cord is properly connected and the socket has power. Then, ensure the safety switch is engaged and the blade brake is released. If still not starting, inspect the fuse or circuit breaker.

How do I clean the underside of the mower deck?

Disconnect the power, tilt the mower on its side (with the air filter facing up), and use a hose or scraper to remove grass clippings. Avoid using a pressure washer to prevent water ingress into the motor.

Is the RLM50 suitable for sloping lawns?

The RLM50 is designed for flat to gently sloping terrain (max 15° slope). For steep slopes, use a self-propelled or robotic mower for safety.

What spare parts are commonly needed?

Common spare parts include replacement blades (part number BL50), grass bag assembly, wheels, and handle grips. Always use genuine G-Technology parts for compatibility.

How loud is the RLM50 during operation?

The noise level is approximately 82 dB(A). Wear hearing protection if mowing for extended periods or in enclosed spaces.

Can I mow wet grass with this mower?

It is not recommended to mow wet grass as it clogs the blade and grass bag, reduces performance, and can slip on the wheels. Wait until the grass is dry for best results.

Thank you for choosing Gtech

"Welcome to the Gtech family. I started Gtech to create sensible, easy to use products that do a great job, and hope you get many years of trouble-free performance from your new product."

Nick Grey – Inventor, owner of Gtech

Robot mowers work by making regular small cuts of the grass to maintain a set height. To do this they must be able to mow the grass multiple times per day every day. This will keep the grass level constantly in check. As it is cutting small amounts regularly the clipping will fall to the ground and are not collected. Over time these small clippings will compost and add nitrogen to the lawn. Eventually this will leave the lawn looking more green and lush and enhance the general health of the lawn.

Don't cross wires No right angles No acute angles Obtuse angles Curves

There may be parts of your garden which will be challenging or even impossible for your Robot Mower. Your Robot Mower will not stray beyond the boundary wire you must lay around your garden.

It will change direction on making contact with things like:

• Posts and poles (e.g. washing lines)
  • Fences and walls around trees

But it will need to be kept away from:

• Dug borders
  • Trees with exposed roots
• Flower beds
• Ponds and water features
  • Excessively uneven terrain.

There is a handy ruler you can press out of the carton that will help you measure 35cm all around your garden.

Don't cross wires No right angles No acute angles Obtuse angles Curves

The cable must be kept taut and never be allowed to loop or cross over itself. Ideally if ground is particularly uneven the wire can be buried up to 15mm deep and pegged down to secure. This can be achieved easily with a manual edging tool. If this is not desired or possible then the wire should be firmly pegged around the garden with pegs at a minimum of 1m intervals, keeping the cable taut to avoid it being cut by the mower, more so at corners and over uneven terrain. The cable should be positioned a minimum of 35cm from the edge of the garden, as the mower will overlap the wire, although it will not stray past it.

On corners the cable should not be laid at a sharp angle or right angle, but curved or a series of obtuse angles. The mower can detect a signal from the wire from as much as 20m away. It should be noted that due to this set up some areas of the lawn will not get mowed such as outside the perimeter edges. These can be maintained using a suitable grass trimmer.

If the ground where the wires are to be laid is particularly dry and the soil hard from lack of rain, it will help to thoroughly water the garden before attempting to lay your perimeter wire.

Rectifying or avoiding problem areas

Obstacles such as tree roots on lawn

Alternatively, cut the tree root back with a saw and fill any resulting uneven surface, then set the perimeter over it.

Excessively uneven areas of lawn

If you don't want to avoid mowing this area, it's best to fill it with soil, compact it down and re-seed it with grass.

If the area is on the perimeter line this can the be pegged out as normal. If it is within the mowing area it should no longer be a problem.

If your mower encounters particularly long grass it may treat it as an obstacle as it could bump the mower's obstacle sensor. The grass needs to be at a reasonable level before the Robot Mower can function correctly.

Installing the charge station

Find a location with access to power, ensuring the mower can leave the charge station in an anti-clockwise direction. Don't peg the plate down yet.

The location of the charge station should be flat and secure, without risk of movement, if placed next to a border edge that is unstable it can slump and cause the station to be uneven, this will cause problems for the mower when returning to charge.

WARNING: Trailing wires are a trip hazard. Take care when choosing your location.

The boundary wire goes into the front (1) of the charge station and comes out at the back (2).

Push the boundary wire into the tube at the front (1) of the charge station.

Push the cover back to it's original position to cover the wires and connections from water ingress.

Making sure the power is switched off at the socket, screw the two charging rods into the holes just below the cover of the base station. Note: This is where the LED status indicator is situated. See page 24.

Laying the perimeter cable

Keep the cable straight for at least the first 2m. This is to allow the mower to return to the charging stand with ease.

Place the pegs at intervals of about 1m on straight and even ground, 30cm to 50cm on bends and corners. Uneven ground and obstacles will require more pegs.

The perimeter wire must be kept tight. If it is loose it may well end up being cut by the mower as it passes over it.

If the wire passes over a moderate dip in the lawn, more pegs will be required to keep the wire firmly pegged at ground level, or it risks being cut.

Operating the mower

Place the mower on the base station with the wheels on the grips and the two pins engaged into the front of the mower. Note: the mower will require to be charged to at least 70% capacity before it will leave its station.

Press the STOP button

This will flip open the control panel and LCD display cover.

Hold the power button (1) down for three seconds to activate the LCD display.

Control panel

Cutting height adjustment

1. Open the knob lid.
2. Cutting height can be adjusted from 2.5cm to 5.5cm by rotating the adjustment knob.

Getting started:

Set the cutting height

The first cut of the season or long thick wet grass will need the highest setting (5.5cm). Gradually reduce to desired height once all ground has been covered. This may take a few days or a few weeks. If the perimeter wire is pegged to the surface of the garden rather than buried, it is a good idea to let the wire “bed in” to the surface of the lawn, during which time it is advisable to keep the mower on an elevated blade setting. NOTE during first few days of mowing the grass may look stripy or patchy where the mower has covered /not covered. This is normal and will become even after several days once the full lawn area has been mowed.

First time out

The control panel will ask for a pass code. The default PIN is AAAA

Pressing the start button and closing the flap will cause the mower to start a perimeter circuit after which it will begin randomly mowing the lawn.

First time out

The first few mows will appear random and unfinished, this is normal. With the multiple passes the mower makes over time, this will even out, and by using zoning and spiral spot mowing a desirable effect can be achieved in less time. These methods are explained on page 21.

New season mowing

Between mowing seasons when the mower is not operating (during winter months) the grass can become unkempt and thickets emerge. On new season setup review mowing pass and address any problem areas.

Repairing the perimeter wire

Diagram showing two green arrows pointing to a gray cylindrical object, no text or symbols present

If the perimeter wire gets cut or breaks for any reason (indicated by solid red light on charge station), you need to locate and repair it. You will need to use one of the splicing clips provided. First take up the slack in the wire so there is some overlap.

The clip has two channels in it. Push one end into one channel and the other end into the other. The wire needs to go right in, and can even protrude from the other end.

Taking a pair of pliers, crimp the metal tab onto the inserted wires. This will form a connection between the wires.

Close the cover of the clip until it clicks securely in place. You will then need to ensure the clip does not protrude on your lawn and risk being cut by the mower, by embedding it in the soil.

When the perimeter wire is repaired the charge station will display a solid blue light. If the light is still red there are more breaks in the loop, which will need locating and repairing.

Replacing the blades

1. Switch the mower off
2. Wear protective gloves
3. Turn the mower upside-down
4. Place blade over raised screw-hole.

1. Use a second screwdriver to anchor the blade plate while you attach the blade.
2. Using a cross head screwdriver, secure the blade on the blade plate. The blade should be able to rotate freely once fitted.
3. Repeat for other blades

Re-orientate the blade (turn it around or turn it upside down) as each corner wears out until all four quarters of the blade have been used. If all four quarters have been used, then replace blade.

Troubleshooting

Error message Cause Solution
Mower outside Mower is outside	the perimeter	Place the mower inside the perimeter.
Mower lifted Mower is lifted away	from the ground	Move the mower to a flat part of the lawn.
Mower tilted Mower is tilted too much.	Move the mower to a flat part of the lawn.
Mower overturned Mower is upside down	Return the mower to its normal position.
Mower trapped Mower is trapped by obstacles.	Remove the obstacles.
Loop signal lost Power supply or the wire is not connected to the station, or wire is broken.	Check the power supply, station and wire are connected normally. Identify wire break and repair with splice connector
Motor fault Blade motor or drive motor is stuck. The motor current is too high.	Clear the grass or soil in cutting means and driving wheels. Cut the high and thick grass with a conventional lawn mower.
High temp The battery temperature is too high.	Wait until the temperature decreases.
Battery abnormal The battery is damaged. Call for help from service centre.

Wheel spinning faults where the mower will stop in a single spot and wheel(s) spin is a combination of uneven and/or wet ground. The solution is to add soil to level the ground. Ensure good drainage of the lawn before mowing, and not to mow during heavy rain and water logging.

If the perimeter wires are in the wrong connectors (so the signal is clockwise not counterclockwise) then the mower will attempt to be outside the perimeter, not inside it. If the mower leaves the area constantly then change the wires around at the charge station (moving the wire in red connector to black and vice versa).

Maintenance

1. Check and clean mower regularly once a week.
2. When you first start using the mower, the blade plate, protections plate and blades should be checked once a month.
3. It is important that the blades and blade plate rotate easily.
4. Blade edges should not be damaged. Blade life depends on the type of grass, soil, lawn etc.
5. Working with dull blades gives a poor mowing result, which needs more power to mow, meaning the mower covers a smaller area at a time.
6. Charge the battery fully at the end of the season before winter storage. If storage time is longer than one year you will need to recharge the mower before use.

Winter storage

1. Mower must be carefully cleaned before winter storage. Charge the battery fully before storage.
2. Store the mower in the station and place in a dry area to protect from frost, preferably stored in the original packaging.
3. Boundary wire can be left in the ground. As the charging station is removed you should protect boundary wire end from moisture with electrical tape.

After winter storage

1. Check whether the mower, boundary wire and charging electrodes need to be cleaned before use. If the charging strips appear to be rusty, clean them by using an emery cloth or suitable abrasive cloth. Check whether the mower's time and date are correct.
2. Check whether the blades need to be changed.
3. Check whether the blades and blade plate turn easily.

Product Care

Wear protective gloves when handling, cleaning or replacing the blade.
