Frequently Asked Questions - ST04 G-TECHNOLOGY

How do I assemble the G-Technology ST04 lawn mower?

Assembly typically involves attaching the handle, grass bag, and securing the lower handle section. Refer to the manual for step-by-step instructions with illustrations. Tools required: Phillips screwdriver.

How do I start the mower?

Ensure the power cord is connected and the safety key is inserted. Squeeze the safety lever (deadman's handle) towards the handlebar to start the motor. Release to stop.

How do I adjust the cutting height?

Use the single-lever height adjustment mechanism near the rear wheel. Move the lever to one of the five positions to set cutting height between 25 mm and 75 mm.

What type of power cord do I need?

Use a heavy-duty outdoor extension cord with a minimum wire gauge of 14 AWG and a rating of 15 A. Keep the cord away from the cutting path.

How do I maintain the mower?

After each use, clean the underside and blades with a hose. Sharpen or replace the blade annually. Lubricate the motor bearings and check for loose bolts. Store in a dry place.

What should I do if the mower is not cutting evenly?

Check for a dull or damaged blade. Sharpen or replace it. Also ensure the cutting height is set correctly and the lawn is not too wet. Inspect the wheel adjustments for proper leveling.

Is the ST04 suitable for mulching?

Yes, the mower supports mulching. You will need a mulching plug (accessory) that blocks the grass outlet. Mulching returns fine clippings to the lawn as natural fertilizer.

Where can I find spare parts for my mower?

Spare parts such as blades, grass bags, and wheels are available on the G-Technology website or through authorized dealers. Use the model number ST04 to find compatible parts.

How do I store the mower during winter?

Drain the fuel if applicable (not needed for electric). Clean thoroughly, remove any debris, and store in a dry, covered area. Fold the handle to save space. Charge battery if cordless (not applicable for corded).

What safety precautions should I take?

Always wear sturdy shoes and eye protection. Never mow in wet conditions. Keep children and pets away. Disconnect power before cleaning or servicing. Use a residual current device (RCD) for added protection.

ORTANT:

YOUR OWN SAFETY AND TANDERS READ THE

INSTRUCTIONS BEFORE OPERATING THE MACHINE.

PLEASE KEEP THE INSTRUCTIONS SAFE FOR FUTURE REFERENCE.

WARNING: When using the machine the safety instructions must be followed.

WARNING: THIS PRODUCT CAN CAUSE SERIOUS INJURIES.

Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

WARNING:

When using any electrical appliance, basic safety precautions should always be observed, including the following, to reduce the risk of fire, electrical shock, or injury.

Work area:

- Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust and fumes.

- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

- Not to be used as a toy. Not to be used near children. Never allow children to use the power tool. When not in use store the power tool out of the reach of children.

•Always be sure of your footing on ladders or slopes, do not over-reach or use on excessively steep slopes.

Electrical safety:

- Power tool plugs must match the outlet. Never modify the plug in any way.

- Do not use any adaptor plugs with earthed (grounded) power tools.

Unmodified plugs and matching outlets will reduce the risk of electric shock.

- Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

- Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the risk of electric shock.

- When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

- If the cord becomes damaged during use disconnect the cord from the power supply immediately- DO NOT touch the cable before disconnecting.

- Before use check the power supply and charger cables for signs of damage or ageing.

- When charging or operating the power tool it is recommended that the appliance should be supplied via a residual current device (RCD) with a tripping current of not more than 30mA.

- Do not handle the charger or the power tool with wet hands.

Personal Safety:

- Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use any power tool while you are tired or under the influence of drugs, alcohol or medication. A moment

of inattention while operating power tools may result in serious personal injury.

•Always be aware of your surroundings and stay alert for possible hazards that you may not be aware of due to concentration on the power tool.

- Use safety equipment. Always wear eye protection. Safety equipment such as non-skid shoes, safety glasses, sturdy gloves and hearing protection are recommended and will reduce the risk of personal injury. - Do not operate when barefoot or wearing open sandals.

•Always wear substantial footwear and long trousers.

- Dress appropriately. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

- Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your fingers on the switches or plugging in power tools that have the switch on invites accidents.

- Remove any adjusting key or wrench before starting the power tool. A key or wrench left in a rotating part of the power tool may result in personal injury.

- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

•Take care in slippery conditions, and on slopes and uneven ground.

- Do not run with the power tool.

- When operating the power tool ensure that both hands are correctly positioned on both handles. Do not operate this product if incomplete or with unauthorized modifications.
