Frequently Asked Questions - HM400 MURRAY

How to adjust the cutting height of the Murray HM400 mower?

Adjust the cutting height by following the instructions in figures 4 and 5 of the manual. Adjust the wheels or knobs according to the model to achieve the desired height.

How to adjust the mower blades?

To adjust the blades, turn the mower over (figure 6). Use a 4 mm hex Allen key to turn the adjustment bolt clockwise to tighten or counterclockwise to loosen. The adjustment is correct when the test paper is cut cleanly across the entire length of the fixed blade.

What to do if the cut is not clean?

Poor cutting may be due to worn or dull blades, or too large a gap between blades. Check the condition of the blades and adjust them according to the adjustment procedure. If the problem persists, contact after-sales service.

How to maintain the Murray HM400 mower?

Clean the mower after each use with a soft brush. Do not use water, solvents, or harsh chemicals. Store it in a dry place and do not place any objects on top. Regularly check the fasteners and blade condition.

What safety equipment should I wear?

Wear safety glasses, hearing protection, sturdy non-slip shoes, and safety gloves that meet standards.

Can I mow on a slope?

Mow across the slope, never up or down. Be careful when changing direction. Do not use the mower on excessively steep slopes.

How to store the mower?

Store the mower in a dry place. Do not place any objects on top and ensure it cannot tip over or roll.

The mower is hard to push, what to do?

Check if the cutting height is too low, if the blades are too tight or clogged with debris. Clean the cutting area and adjust the blade setting if necessary.

Can I use the mower without the grass catcher?

Yes, you can use the mower without the catcher, but the cut grass will be left on the lawn. Make sure to only push the mower forward.

What to do in case of abnormal noise?

Abnormal noise may come from worn blades, loose fasteners, or excessive contact between blades. Check and tighten fasteners, adjust blades, or contact after-sales service.

INTENDED USE

• This product is intended for domestic lawn mowing only.
• The reel blades should rotate when the wheels turn. Both wheels should touch the ground while mowing.

NOTE:

• The mower should never be operated with the wheels off the ground. It should only be used by pushing in a forward direction at ground level and must not be ridden on.
• It should not be used to cut anything other than domestic grass lawns.
• Do not use the product for any task, except for that which it is intended.

Precautions

• The following safety precautions must be strictly observed to avoid the risk of damage or personal injury.
• Do not allow children or people unfamiliar with these instructions to use the mower.
• Do not operate the mower when fatigued, ill or under influence of alcohol, drugs or medication.
• Before using the mower, check and ensure that the blade assembly is not worn or damaged. Damaged or worn blades are major hazards.
• Check all fasteners regularly. Always ensure the mower is in a safe operating condition.
• Make sure the lawn is clear of sticks, stones, bones, wire and debris before mowing. These could be thrown by the blades and cause injury or damage.
• Mow only in good daylight.
• Stop mowing before adjusting the cutting height and when emptying the grasscatcher.
• Mow across the face of a slope, never up or down. Use extreme caution when changing direction on a slope. Do not mow on excessively steep slopes.
• Walk with the mower, never run.

Precautions

• Never lift, carry or tilt the mower when the blade is rotating.
• Never intentionally strike an obstacle such as trees or mow tall weeds, tall and heavy grass, and hidden objects such as sticks. Slips and trips resulting from sudden stoppages, uneven ground and unbalanced movements may result in serious injury.

ASSEMBLY

OPERATING

Mowing Tips.

1. Worn or damaged blades will reduce lawn finish and will not cut properly. Check and inspect them regularly.
2. To maintain cutting performance, keep the mower clean and the area to be mowed free from any debris.
3. Cut the grass regularly to avoid it becoming too long and making it difficult to push.
4. The cutting pattern should be varied from week to week (eg. North-South to East-West).
5. As a general rule, only cut the top one third of the grass length (approximately). More than this may leave an untidy appearance and finish.
6. Walk at a good, steady pace. Avoid walk at a slow, unsteady pace as the reel mower tends to bind up and skid.

Maintaining the mower

• If the mower begins to operate abnormally or if it strikes a foreign object - STOP mowing. Inspect the mower and blades for any damage.
• Regularly inspect and check for any worn or damaged components. Replace if required.
• Regularly check all accessible fasteners. Retighten or replace if required.
• The cutting mechanism on your lawnmower is already preset to the factory setting.
• The blades should be adjusted if the grass is not cut cleanly and evenly or if the mower is difficult to push. Always check the cutting performance before use and adjust if needed.

Image 6 - Mower upside down view

• Keep the mower on a stable and flat surface.

• Keep hands and feet away from rotating blades. These blades are sharp and can cause serious injury. When handling the blades for adjustment or maintenance tasks, always wear protective gloves.

• Turn the mower upside down as shown in figure 6. Detach the grasscatcher and the handle assembly (if required).

• Feed a strip of paper (80gsm) (A) about 1" to 2" wide between the reel blades (B) and the fixed blade (C).

• Turn the reel blades slowly by hand in the direction shown by the arrow in figure 6 and check if the paper is cut as the first reel blade passes. Repeat this process for the entire length of the fixed blade and the paper should cut cleanly and evenly. The blades act like a scissor.

• If the paper is not cut cleanly and evenly, use a 4mm Hex Allen key (D) and turn it clockwise approximately 1/8th of a turn to tighten the adjustment bolt (E) on both side until the reel blades lightly brushes the fixed blade.
• If the reel blades and fixed blade make in contact and it becomes difficult to turn the reel blades by hand, use hexagon allen key and turn it anticlockwise to loosen the adjustment bolt on both sides. Repeat step 2 & 3 for checking.

NOTE:

• The adjustment bolts should be equally adjusted to avoid misalignment between the reel blades and the fixed blade.
• Do not overtighten the adjustments bolts as this could damage the fixed blade.

Cleaning and Storage

• Clean the mower thoroughly after each use using a soft brush.
• Do not use water, solvents, polishes or any aggressive cleaning agents.
• Do not immerse the mower or any part of it in water.
• Store the mower in a dry place.
• Do not place other objects on top of the mower during storage.

The mower is not freestanding and care should be taken to ensure the mower does not tip, fall or roll during storage.
