Frequently Asked Questions - 721-231 Meec Tools

How do I start the snow blower?
Ensure the power cord is connected to a grounded outlet, then press the safety switch and pull the starter handle.
What type of extension cord should I use?
Use a heavy-duty outdoor extension cord rated for at least 2000W and with a grounded plug. Keep it away from the auger.
How do I adjust the chute direction?
Turn the chute crank (if equipped) to rotate the chute 180°, or manually adjust the deflector for snow height.
What should I do if the snow blower clogs?
Turn off the motor and disconnect the cord. Use a cleaning tool (not hands) to remove debris from the auger and chute.
How do I maintain the snow blower?
After each use, clean the housing and auger with a brush. Check bolts for tightness and oil the axles occasionally.
Is it safe to use in wet snow?
Yes, but wet snow is heavier and may clog more easily. Work slowly and clear regularly to prevent overload.
What is the maximum snow depth it can handle?
The snow blower can handle up to 30 cm (12 in) of light, fluffy snow. For deeper snow, make multiple passes.
How do I store the snow blower for the summer?
Completely clean and dry the unit. Apply lubricant to moving parts, and store in a dry, covered area away from moisture.
Can I use an extension cord with a smaller gauge?
No. Always use a cord with gauge 12 or thicker to avoid voltage drop and overheating. Longer runs require thicker wire.
Where can I find replacement parts?
Contact Meec Tools support or visit their website. Parts like auger blades, belts, and switches are typically available.

WEAR HEARING PROTECTION

The declared vibration value, which has been measured by a standardised test method, can be used to compare different tools with each other and for a preliminary assessment of exposure.

WARNING The vibration during actual use may deviate from the stated value, depending on how the tool is used. It is therefore necessary to determine which safety precautions are required to protect the user, based on an actual operating conditions, taking into account all stages of the work cycle, e.g. the time when the machine is switched off and when it is idling, in addition to the time the power switch is on.

The figures stated are actual measured sound levels, which may not be necessarily safe to work with. Whilst there is a correlation between the stated sound level and the sound level experienced, this cannot be used reliably to determine whether or not safety precautions are required. Other factors influence noise levels in each individual case, for instance the acoustics in the work premises and any other sources of noise such as other machines or processes. The admissible sound level values can also vary from country to country. Users are obliged to determine any risks.

  3. Keep the auger engaged for about 10 seconds and then release the auger lever. Repeat several times.
  4. Allow the engine to run with the auger lever disengaged. Go to the front of the machine.
  5. Check that the auger has come to a complete standstill and does not move.
  6. Start the engine and check that the auger engages and disengages correctly.

Check that the drive lever and the gear lever work in accordance with the instructions below.

  1. Turn off the engine and put the gear lever in the highest forward gear. Engage the drive lever and push the machine forward. The machine should move forward. Press in the drive lever. The wheels should stop moving.
  2. Disengage the drive lever and push the machine forward again.

  3. Move the gear lever to the highest reverse gear and back to the highest forward gear. It must be easy to move the gear lever and the wheels should rotate.

  4. If the lever is stiff or if the wheels stop moving, loosen the lock nut on the drive lever cable and extend the cable by turning the nut one turn.
  5. If the wheels do not stop moving when you engage the drive lever, loosen the lock nut on the drive lever cable and shorten the cable one turn of the nut.
  6. Repeat the check and adjust again if necessary. Tighten the lock nut after adjustment.

SWITCHING OFF

  1. Close the fuel tap.
  2. Remove the ignition key to prevent unintentional or unpermitted starts. Keep the key in a safe place. The engine cannot start without the ignition key.
  3. Wipe all the levers on the engine dry.

CLEARING THE EJECTOR CHUTE

The clearing tool is attached at the back of the auger hood.

Clear the ejector chute according to the instructions below.

  1. Disengage the auger lever and the drive lever.
  2. Stop the engine by pulling out the key.
  3. Remove the clearing tool from its holder.
  4. Clear away snow and ice using the clearing tool.

WARNING Never use your hands to clear the chute. Use the clearing tool or a stick.

Put the clearing tool back in its holder and start the engine.

Stand in the operating position behind the handle and engage the auger lever for a few seconds to eject any snow and ice remaining in the ejector chute.

TIPS!

NOTE: Let the engine run for a few minutes. The engine does not produce maximum output until it reaches operating temperature.

WARNING The muffler, muffler guard and other engine parts can get very hot during use - risk of burn injuries.

  1. Clear the snow as soon as possible for the best results.
  2. If possible aim the ejector chute in the direction of the wind.
  3. Let each row overlap the previous one.

  4. The skids are normally placed 6 to 7 mm below the glide plates. If the snow is well packed, the skids can be moved upward to allow the glide plates to get closer to the ground. When driving on gravel, the skids can normally be sunk to lift the glide plates off the ground.

  5. Once work is completed, let the machine run for a number of minutes until all the snow is ejected. Otherwise the snow can freeze causing the auger to get stuck.
  6. Clean the machine carefully after each use.

MAINTENANCE

WARNING Turn off the engine and disengage all the control levers and wait until all moving parts have come to a complete standstill before performing repairs, lubrication and/or inspection.
