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 3). Do not overfill, the oil tank capacity is
0.55 litre. 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. Do not overfill, the petrol level should be below the bottom of the fuel tank neck..
Ensure that the spark plug lead is securely connected to the spark plug.
Move the throttle control to the “Choke” position (Figure 4).
Pull and hold the Operators 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 move the throttle control from “Choke” to the “Fast” position.
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: Using the choke is usually unnecessary when starting a warm engine. However, in cool weather it may
still be necessary to use the choke to start the engine.
STOPPING YOUR MOWER
Release the Operators 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 5)
