PREPARATION
When mowing, always wear solid footwear and long pants, do not operate the device without
shoes or wearing sandals.
Check carefully the area where the device will work and remove all stones, branches, wires,
bones and other foreign objects.
In high grass, you may not notice obstacles (e.g. stumps, roots), so before starting work with the
device, mark all obstacles hidden in the grass that cannot be removed.
Always check the blades, bolts and knife assembly for wear and damage before use. Replace
worn or damaged knives and bolts in pairs to maintain balance.
In the case of multi-knife devices, be careful, because the rotation of one knife may cause the
rotation of other knives.
KNIFE SHARPENING
To ensure optimal working conditions for the mower, the machine's knife should be sharpened.
This seemingly simple operation must be carried out with special care. It requires a lot of
technical knowledge and necessary service equipment. The manufacturer is not responsible for
any damage to the mower related to improper knife sharpening.
The recommended angle is 30 °.
It is safe to have the knife sharpened by an authorized MURRAY service center.
Before sharpening, the mower should be turned off, allow the engine to cool down, remove the
high voltage cable from the spark plug, if necessary remove the battery and unscrew the knife.
The knife can be sharpened manually, using a whetstone or a suitable metal file, it is preferable
to sharpen with a professional sharpener, all the time bearing in mind that the blade may
overheat, thus it will not be suitable for work. It is recommended to use liquid coolant for
metalworking, it is permissible to use water all the time, bearing in mind that not all sharpening
machines can work in the coolant stream. The blue surface of the blade indicates damage to the
knife, which should no longer be used.
After each sharpening, the knife must be balanced. If the user does not have a balancing
machine and the appropriate knowledge, it is necessary to return the knife to a specialized
service for balancing. Working with an unbalanced knife causes excessive vibration and, as
a consequence, may cause loosening of the screw connections of the entire device, including the
knife attachment screw, which may be dangerous to the health and life of the user.
USAGE
Mow only in daylight or in good artificial light.
Do not mow during rain, especially during a storm. Avoid mowing wet grass.
Always make sure that your legs stand firmly on the slope.
