STARTING YOUR MOWER
Read and understand the Safety Precautions before using your mower.
• Put Mountfield 4-stroke, or an SAE 10W-30 oil, in the oil filler (Figure 5). Do not overfill, the oil tank capacity is 0,45
litres. Mountfield oil, part number MX855, is available from any Mountfield stockist or B&Q store.
• Fill the fuel tank with UNLEADED petrol. Use only clean, fresh petrol - stale fuel may contain deposits that will
clog the carburettor. Unleaded fuel can start to go stale after just 28 days. Do not overfill, the petrol level should be
below the bottom of the fuel tank neck. Do not over tighten the fuel cap. The fuel cap breathes through the threads
of the cap and over tightening can cause the engine to cut out.
• Ensure that the spark plug lead is securely connected to the spark plug.

• Press the PRIMER button 3 times to prime the carburettor (Figure 6).
• Pull and hold the Operator Presence Control (OPC) lever against the handle to disengage the engine brake.
THE ENGINE WILL NOT START, OR CONTINUE TO RUN, UNLESS THE OPC LEVER IS HELD AGAINST
THE HANDLE
• Pull the starter cord with a strong smooth pull. Do not remove the pull cord from the guide.
• When the engine starts let go of the pull cord.
• To engage the drive to the rear wheels on Self Propelled models, pull and hold the clutch lever against the handle.
• To stop the drive, release the clutch lever.
NOTE: It is not normally necessary to use the “PRIMER” button when starting a warm engine.
STOPPING YOUR MOWER
• Release the Operator Presence Control (OPC) lever; this will engage the engine brake and operate the ignition
safety cut out device.
ADJUSTING THE HEIGHT OF CUT
The height of cut adjustment not only determines the length
of the cut grass, it also controls the airflow which carries
clippings into the collector. If the discharge chute becomes
blocked, increase the airflow by raising the height of cut. To
prevent blockages when cutting long, thick grass, set the
adjustment to the highest setting and cut the grass; then cut it
again on a lower setting.
To adjust the height of cut:
• Stop the engine and disconnect the spark plug
• Put the mower on a level surface
• Adjust the cutting height lever by pulling outwards and
moving into the required position (Figure 7)
• All 4 wheels must be at the same height
