Before Operation
Engine Oil (Picture J)
The mower is shipped without oil in the engine.
All engines are run at the factory prior to packaging. Most of the oil is removed prior to shipment; however, some oil remains in the engine. The amount of oil
left in the engine varies.
Add enough oil to bring the oil level between the upper and lower limit marks on the dipstick as shown. Do not overfill engine with oil
Fuel (Picture K)
Notice: Engine delivered without gasoline, refuel 1.0 litter of before starting the engine.
• Remove the filler cap
• Add fuel to the bottom of the fuel level limit in the neck of the fuel tank. Do not overfill. Wipe up spilled fuel before starting the engine.
• Tighten the fuel tank cap
Gasoline is extremely flammable, and gasoline vapour can explode, causing serious injury or death. Use extreme care when handling gasoline. Keep out of
reach of children.
Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refuelled or where gasoline
is stored. Avoid repeated or prolonged contact with skin or breathing of vapour.
After refuelling, tighten the fuel tank cap securely. If any fuel was spilled, make sure the area is dry before starting the engine.
Charging the battery (Picture L)
Charge the battery before use Before the electric start function is used, the battery must be charged for 5 hours. Put the charger plug into the hole in the
battery and connect the charger to a power supply.

• Move the choke lever to the “CHOKE” position (Not equipped on all models).
* Note: Not all models have this choke lever.
• Pull back on the brake lever and hold it against the handle.
• Release the clutch lever. This will prevent the mower from moving forward when you operate the starter.
* Note: Not all models have this clutch lever.
• If the models have electric start function, please press the E-starting button lightly, the engine will be started.
* Note: Not all models have Electric Start Function.
• With the starter handle in its support, take the starter handle with your right hand and pull slowly as far as to have a resistance, then pull energetically on
the starter handle with starter rope through the support (If the cold start is not sufficient enough, repeat this operation 2 or 3 times).
• Immediately after the start, push back the choke lever from “CHOKE” position to “RUN” position (If the temperature is low, allow the engine to run for a
few minutes before starting to work).
* Note: Not all models have this choke lever.
Operation The Controls for Mowing (Picture P1-P6)
Blade is in action as soon as engine started. While the machine is working maintain the security handle in working position. The engine will stop as soon as
you release the engine control bar.
Release the lever to stop the engine whenever you need to leave the mower.
Clutch Lever
Push the clutch lever forward and hold it against the handlebar to propel the mower forward.
Release the clutch lever to stop the mower’s forward movement.
Always release the clutch lever before starting the engine. If the clutch is engaged, the mower will move forward.
Operate the clutch lever with a quick and complete motion, so the clutch is either fully engaged or fully released. Hold the clutch lever against the handlebar
during self-propelled mowing. This will help to extend the service life of the clutch mechanism.
Throttle Lever
For best cut quality, always mow with the throttle lever in the “FAST” position. When the blade rotate at the preset fast speed, it creates a strong fan action
that lifts and cuts grass more efficiently.
* Note: Not all models have this Throttle lever.
