2. Setup and Assembly
The Gilmour RM30 reel mower requires minimal assembly. Follow these steps to prepare your mower for use.
Required Tools:
- Phillips head screwdriver
- Socket wrench set (10mm socket recommended for handle bolts)
Assembly Steps:
- Unpack Components: Carefully remove all parts from the packaging. Verify that all components, including the mower body, handle sections, and grass catcher, are present.
- Assemble the Handle: Attach the lower handle sections to the mower body using the provided bolts and nuts. Ensure all connections are secure. Connect the upper handle section to the lower sections.
- Secure Handle Fasteners: Hand-tighten all handle bolts initially. After initial assembly, use a Phillips head screwdriver and a 10mm socket wrench to firmly tighten all bolts and screws on the handle. Periodically check these fasteners for tightness during use.
- Attach the Grass Catcher: Hook the grass catcher onto the designated attachment points at the front of the mower. Ensure it is securely seated to prevent it from detaching during operation.
- Inspect Mower: Before first use, visually inspect the mower for any loose parts, damage, or obstructions. Ensure blades rotate freely.
3. Operating Instructions
Proper operation ensures effective cutting and extends the life of your Gilmour RM30 reel mower.
Before Mowing:
- Clear the Area: Remove all debris, such as sticks, stones, toys, and pine cones, from the lawn. These can damage the blades or impede mower function.
- Adjust Cutting Height: The cutting height can be adjusted from 1 to 3 inches. Locate the bed knife adjustment mechanism and set it to your desired height. For best results, avoid cutting more than one-third of the grass blade length at a time.
- Check Grass Conditions: Mow when the grass is dry. Wet grass can clump, clog the mower, and result in an uneven cut.
Mowing Procedure:
- Pushing the Mower: Push the mower forward at a steady, comfortable pace. The reel blades will rotate as the wheels turn, shearing the grass against the bed knife.
- Overlap Passes: To ensure an even cut, overlap each mowing pass by a few inches.
- Using the Grass Catcher: The detachable grass catcher collects clippings. If the grass is very tall, the catcher may not collect all clippings efficiently. You may need to empty it frequently or make multiple passes.
- Maneuvering: The dual-wheel design provides stability. For turns, slightly lift the front wheels and pivot the mower.
- Avoid Obstacles: If you encounter an obstacle, stop pushing and lift the mower over it. Do not force the mower over large objects.
4. Maintenance
Regular maintenance ensures optimal performance and longevity of your Gilmour RM30 reel mower.
After Each Use:
- Clean the Mower: Brush off grass clippings and debris from the blades, wheels, and mower deck. Do not spray the mower with a hose, as this can lead to rust.
- Lubricate Moving Parts: Apply a light lubricant, such as WD-40, to the moving parts of the reel and wheel axles to ensure smooth operation and prevent rust.
- Inspect Fasteners: Check all bolts and screws, especially those on the handle, for tightness. Tighten any loose fasteners to prevent components from detaching during use.
Periodic Maintenance:
- Blade Inspection: Although the blades are self-sharpening, periodically inspect them for excessive wear or damage. If significant damage occurs, professional servicing may be required.
- Storage: Store the mower in a dry, covered area to protect it from the elements. The handle can be folded or removed for compact storage.
5. Troubleshooting
This section addresses common issues you might encounter with your Gilmour RM30 reel mower.
Common Issues and Solutions:
- Mower is Loud or Squeaking:
- Cause: Lack of lubrication on moving parts or contact between blades and bed knife.
- Solution: Apply lubricant (e.g., WD-40) to the reel axle and blade contact points. Ensure the bed knife is correctly adjusted and not overly tight against the reel blades.
- Mower Not Cutting Effectively / Uneven Cut:
- Cause: Grass is too tall, wet, or debris is obstructing blades; incorrect cutting height; dull blades.
- Solution: Mow when grass is dry and not excessively tall. Clear all debris from the lawn. Adjust the cutting height to a lower setting if necessary, but avoid cutting more than one-third of the grass blade at once. Ensure blades are clean and free of buildup.
- Grass Catcher Not Collecting Clippings:
- Cause: Catcher is full, improperly attached, or grass is too tall/wet.
- Solution: Empty the grass catcher frequently. Ensure it is securely attached to the mower. Mow when grass is dry and at a manageable height.
- Loose Parts / Wheels Detaching:
- Cause: Fasteners have loosened over time.
- Solution: Regularly inspect and tighten all bolts and screws, especially on the handle and wheel assemblies. Apply thread locker if a bolt repeatedly loosens.
