How do I change the engine oil?

Regular oil changes are critical to keeping your engine in optimum running condition and minimizing wear. Be sure to replace oil after every 25 hours of operation, it’s recommended that you refer to your engine manual
1. Siphon off any excessive gas onto an empty container, ensure that your tank is empty
2. Ensure that the unit is in a well-ventilated area and remember to drain the oil before the engine gets cold. If the engine has cooled, allow it to idle for a few minutes before proceeding as this will improve the oil’s viscosity and enhance draining.
3. Find the colored spark plug located near the side of the engine after you lift the engine hood. Ensure that you disconnect the circuitry by pulling out the black ignition wire carefully.
4. Clean the area around the dipstick and the proceed to drain
5. Place a suitable empty container beneath the unit and wait for all the oil to completely drain out.
6. After all the oil has drained, close the oil drain.
7. Fill the unit with fresh oil up till the recommended mark before tightly closing the sump.
8. Start the engine and allow it to run for a minute before usage.

How do I change the mower’s deck blades?

Regularly replacing, sharpening and balancing your mower’s blade will ensure that your lawn is trimmed
perfectly year-round – a blunt blade may cause severe vibrations and can harm the mower’s deck.
Ensure you regularly inspect your blades for dents and damage.
1. Park the mower on a flat, level surface and engage the hand brake
2. Remove the mower’s deck – ensure that you have waited for a few seconds after turning off the
engine as parts may still be moving in the unit.
3. Take out the mounting equipment and unfasten the mower’s blade from the spindles
4. Inspect the blade for dents and abrasions. Sharpen as necessary and check that both ends of the
blade are uniformed balanced. Aim to attain an equal thickness at both ends. If the blade has
been cracked or bent, do not attempt to sharpen and replace with a new blade.
5. Coat the new blade with a thin layer of lubricant before inserting it into the crankshaft.
6. Refasten the mounting hardware tightly and reconnect the deck to the unit.

How do I adjust the steering brake?

The steering brake should ideally be washed with water after each use to clear away dust and accumulated debris. All bolts and fasteners must be periodically inspected to determine the stage of the brake’s life.
1. Park the mower in a flat, level surface and engage the parking brake.
2. Proceed to loosen the jam nuts on each of the brake rod’s assemblies before continuing to turn the adjusting nuts. Bring the brake handle’s crossbar to lay parallel to the instrument panel.
3. After moving the brake handlebar completely to the right side, measure the distance from the right end edge to the right end of the instrument panel. Move the handlebar now to the left all way and repeat the same measurement from the other end.
4. Now proceed to carefully adjust the nuts such that the final difference between the two initial measurements is between 13 to 19mm. Turn clockwise to increase the distance and counterclockwise to decrease the distance before tightening the jam nuts.
5. Continue to loosen the jam nuts at the point below the compression spring, until one of them has attained the desired tightness or tension for the corresponding brake. Ensure that you replace the brake shoes if the lining has worn away significantly.
6. Tighten both the jam nuts securely.

How do I change my mower’s battery?

If you’re consistently having trouble cranking your engine to a start despite cleaning the spark plugs and inspecting other issues, the battery may need to be changed. Replacing the battery is also necessary when the terminals have undergone significant corrosion.
1. Place the hood in the recommended service position as shown in the instruction manual before disconnecting the negative and positive terminal cables
2. Remove the battery along with its bracket from the unit.
3. Inspect the battery’s terminals – clean out any debris and dirt that may have accumulated over time. If the terminals have undergone oxidation and cannot be cleaned, discard the battery – batteries contain lethal chemicals and must be disposed of appropriately.
4. Install the new battery along with the bracket into the unit and reconnect the appropriate positive and negative terminal cables. Ensure that you apply a thin layer of grease on the terminals before reconnecting – it’s recommended that you use dielectric lubricant or petroleum jelly.
5. Fasten the assembly securely and turn on the engine.

How do I replace the mower’s air cleaner?

It’s important the you occasionally clean and replace the air cleaner as well as the cleaner element periodically to keep your engine from clogging or stalling. A blocked air cleaner can choke the engine and drastically lower fuel economy. Ensure that you replace the element after every 100-200 hours of usage.
1. Open the hood and locate the air cleaner housing unit at the side of the engine
2. Clean the area around the housing and remove the air cleaner gently to prevent loose debris from falling into the housing.
3. Gently tap the cleaner a few times against a flat surface to remove stuck debris. Do not attempt to wash or dry the cleaner. If it’s not possible to clean the element, it is time to replace it with a new one.
4. Before reinserting the new element, soak it in fresh engine oil and wait for excess lubricant to drip off.
5. Ensure that the back plate is securely fastened to the rear of the carburetor when replacing the cleaner element.
6. Make sure that the surfaces of the gasket like flush with the back plate to create a tight seal.

How do I adjust the forward-rear clutch assembly?

Ensure that you check your unit’s forward-rear clutch assembly after every 25 hours of operation and re-
adjust as required. Wait for the engine to come to a complete stop before working on the clutch assembly.
1. Inspect the direction control lever for stopping at 15 degrees past the vertical point to the rear.
2. Loosen the rod jam nuts at the control end of the forward-reverse control rod
3. Adjust the position of the rear nuts enough to prevent the lever from moving past the 15 degree mark to the vertical point at the rear.
4. Ensure that the large spring’s coils have a clearance of 0.010’’ as this indicates correct adjustment of the clutch.

How do I replace the PTO clutch in my mower?

If you are unable to engage your blades despite the mower’s engine running smoothly, there may be an issue with the unit’s PTO clutch assembly. The PTO is responsible for power transmission to the blades and might need to be replaced if not functioning properly.
1. Locate the power supply cord connecting the clutch to the engine/battery and disconnect it.
2. Unfasten the housing by removing the bolt, washer and finally the retainer out of the middle of the clutch.
3. Slide the old worn out clutch off the crankshaft, use a mower socket wrench if required as the unit may have become clogged by accumulating debris and clippings.
4. Lubricate the surface of the replacement unit with a light coat of oil.

5. Reassemble the PTO assembly in the crankshaft and replace the bolts and washer – ensure that the bolt has been tighten securely enough to provide a compact seal.

How do I adjust the mower’s throttle?

Adjusting your mower’s throttle response may be necessary from time to time depending on your mowing conditions. In colder weather, it may be necessary to increase throttle output in order to assist cold engine starts and prevent stalling.
1. Park the mower and turn off the engine. Move the throttle control lever forward to the ‘fast’ position.
2. Proceed to move forward the throttle towards the ‘choke’ position taking care that the arms remain aligned.
3. After advancing the throttle to the fast setting, insert a drill bit into the aligned holes and pull up the throttle cable against the side of the panel. Now tighten the clamp screw.
4. Pry back the cap on top of the adjustment screw and gently turn the exposed screw by a little less than a half turn.
5. Shift the throttle back to the slow position and then turn the idle stop screw counterclockwise. Proceed until the screw has cleared the panel by two turns.
6. Start the engine and shift the throttle to the medium position – let the engine idle for a few minutes in the setting. Then shift the throttle back to the slow setting.
7. Adjust the idle stop screw with the spark plug wire assembly – turn clockwise to increase engine speed and counterclockwise to reduce speed. Once you attain the desired rpm, reinstall the black limiter cap.
