Frequently Asked Questions - YT-GC380 Cotech

How do I adjust the cutting height?

Undo the knobs on each side of the rear roller, adjust to desired height (15–40 mm), ensure both sides are equal, then tighten the knobs. Wear protective gloves.

How do I adjust the blade cylinder to the cutting bar?

Undo nut A on each side, turn the adjustment knobs clockwise to reduce clearance or anticlockwise to increase. The blades should just touch the cutting bar and cut paper like scissors. Retighten nuts after adjustment. Wear gloves.

Why is my lawn mower difficult to push?

Check for compacted grass or obstacles preventing cylinder rotation. Also ensure blade clearance is not too tight. Refer to the Operation section for adjustment.

How should I clean the lawn mower?

Clean the exterior with a soft brush or cloth. Do not use water or solvents. For blade area, lay mower on its side and remove debris with wood or plastic to avoid blunting blades. Wear gloves.

How often should I oil the blades?

Oil the blades lightly before storing the lawn mower for prolonged periods. Regular maintenance ensures smooth operation and prevents rust.

Can I use this mower on wet grass or slopes?

No. The manual advises not to mow wet grass (slipping hazard) and to always mow across slopes (not up/down). Avoid steep slopes entirely.

What should I do if the cutting results are unsatisfactory?

Check blade clearance: if too far apart, adjust cylinder closer to cutting bar. Also ensure blades are sharp and undamaged. Refer to Operation section.

Do the blades need sharpening?

The blades are self-sharpening provided the cutting bar is set properly. If cutting remains poor, inspect for damage or adjust clearance.

How do I assemble the handle?

Join the upper handle to the handle uprights using bolts and spanner. Bolt the handle uprights to the lower handle. Attach the assembly to the mower by squeezing handle ends over lugs and inserting split pins.

What safety precautions should I take?

Keep children and pets away. Always wear long trousers and sturdy footwear. Do not use when tired or under influence. Keep hands and feet away from rotating blades. Ensure guard is not damaged.

• Do not use the lawnmower if the guard is damaged or missing.
  • Never use the lawnmower when you are tired, under the influence of alcohol or medicine.
• Inspect the lawn before beginning to mow to make sure that there are no foreign objects which could damage the lawnmower or be flung out from the blades and cause damage.

Operation

Setting the cutting height

2. Make sure that the height is the same on both sides.
3. Tighten the adjustment knobs again.

Adjusting the blade cylinder to the cutting bar

Note: Wear protective gloves.

Note: The cutting bar should be as close to the blade cylinder as possible. The blades should come into contact with the cutting bar but there must be enough clearance for the cylinder to be turned by hand.

1. Undo the nut A (one on each side) and adjust the clearance using the knobs (6).

2. To increase the clearance, turn the knobs anticlockwise. To reduce the clearance, turn the knobs clockwise.

3. Adjust the blade cylinder so that the entire length of the blade touches the cutting bar. It can take a bit of adjusting to get the blade clearance right.

4. The blades are set correctly if they cut a piece of paper placed between the cylinder and cutting bar just as well as a pair of scissors. Test this by turning the cylinder by hand. Note: Wear protective gloves. Bear in mind that the blades are sharp.

5. When the adjustments have been made, retighten nut A.

How to mow

A hand lawnmower works best on a well-kept lawn.

For best results:

• Do not walk too slowly; the cylinder needs to rotate quite quickly for a clean cut.
• Do not let your grass grow too tall. Mow your lawn with a motor-powered mower first if the grass is too tall or if it has too many weeds.
• Mow in straight lines and slightly overlap the row that has just been cut.

Care and maintenance

• Inspect the lawnmower regularly to make sure that all bolts and nuts are tight and that there is no visible damage.
• Clean the exterior of the lawnmower with a soft brush or cloth. Do not use water or solvents.
• Lay the lawnmower on its side to clean the area around the blades. The blades are sharp, wear gloves. Remove any grass and twigs with a piece of wood or plastic so as not to blunt the blades.
  • Store the lawnmower in a dry place.
  • Oil the blades lightly before storing the lawnmower.
  • The blades on the cylinder are self-sharpening provided the cutting bar is set properly.
