Please first read your instruction manual, as most of the information you require is contained in the manuals.
To find the manual go to Manuals and Parts List and select.
What about using fuel modifiers?
Currently we do not have information or experience using these products.
If you happen to make a 25 or 30 to 1 mix, it is ok to use, but long term use will carbonise the spark plugs, and exhaust. Many manufacturers recommend this mix for first few hours of operation to run motor in.
Measure amounts for 40:1 is 100ml oil for four litres of petrol, or 80ml oil for one litre of petrol for 50/1 fuel mix.
Always use a funnel or pouring nozzle into fuel tank of engine to reduce fuel spills over motor etc.
Honda recommends the following – Detergent oil, SAE10W-30
Change oil every 20 hours, that is, weekly if engine is used 4-6 hours per day. In very hot and dusty conditions change more frequently.
Empty and clean out fuel tank. Refill with new clean fuel/mix with 2 stroke oil (50:1 grade) at 40:1 mix. For 4 stroke use straight unleaded petrol (no oil mix).
Press Primer 20-30 times to clear lines and restart.
If it fails to start take to a service dealer.
For further details visit our “Engine Fault Diagnostic Chart” in the “Download Manuals” section.
Use quality non-ethanol based unleaded gasoline 50:1 mix for 2 stroke engine (using 50:1 grade
2-stroke oil), with 80ml oil to 4 litres petrol and quality 4 stroke oil in 4 stroke engine. Use non-ethanol based gasoline.
If you are not going to use the unit for a period of time, eg. not within the next 3 – 4 months, drain fuel from tank. Start motor and allow it to run until it stops to clear fuel from carburettor.
Keep inside Edger blade cover clean. Also, Tillers under the tine covers.
After 2 or 3 years have your dealer check fuel lines and replace if necessary, check air and fuel filter for cleanliness and damage and ensure petrol cap is sealing correctly, no leakage. They will also test and run unit and adjust carburettor if required.
Unfortunately you did not follow the instructions, did not allow blade to spin freely and you damaged the unit.
1. Take to dealer
2. Follow these instructions –
1. Squeeze excess oil out of filter element.
2. Excessive oil in fuel mix causing “spit back” through carburettor to inside of filter box.
3. Spilling fuel over fuel tank when refuelling. The excess fuel is sucked up through air cooling system on some models and through filter box excessively depositing fuel/oil mix on air filter.
|Problem||Engine will not run or runs and stops|
|Cause|| 1. Ignition switch is OFF.
2. Choke ON.
3. Partially empty fuel tank.
4. Primer bulb not pushed enough times.
5. Engine is flooded.
6. Dirty or blocked fuel or air filter.
7. Incorrect jet adjustment.
8. Electric models, motor does not switch on.
9. Petrol cap valve closed
|Action|| 1. Ignition switch to be in run position.
2. Push choke off (down).
3. Fill tank.
4. Press primer bulb fully and slowly 5/10 times.
5. Use correct start procedure.
6. Clean or replace fuel or air filter.
7. Re-adjust jets.
8. Check switch and cables. (Item 24)
9. Clean with compressed air or replace.
A good time to change your blades is when you reach the 2 marker holes in the blade. Use only genuine Atom blades, part number 43105, which are made from a special spring steel to absorb hits on concrete and to reduce impact through gear box system. See also (22).
NON-GENUINE ATOM EDGER BLADES
Use of non-genuine ATOM parts can damage gear box and voids any and all warranty.
These types of blades should NOT be used on any model Atom Lawn Edger due to –
- heavy mass weight, thickness of blade/out of balance, warping creating vibration and overloading of the gear mechanism of Atom Edgers.
These blades do not absorb shock, which is taken by the Edger gear system and subsequent damage.
A safety issue arises as solid one piece blades are heavier and take longer to stop spinning when motor is turned off or reduced to idle due to their heavier weight and flywheel effect.
Atom twin Cross Blades absorb shock and excessive loading and have been proven over 15 years not to damage the Edger gear system
Beware of blades advertised as Atom Blades, or “superseded by”, “replaces”, etc being “passed off” as Atom Blades. This is a trademark infringement, and are false and misleading statements.
Atom Edger Blades are supplied in a sealed white plastic pack branded ATOM with clear instructions on “How to fit” and promoting other Atom products on the reverse side, except for the old yellow bodied Atom Electric Edger which are in a yellow plastic pack. Any other packaging is not an Atom product. Non-packed Atom blades are not a genuine Atom product. See (22) and if used on Atom Edgers will void the warranty.
HOW DO I CHANGE MY ATOM BLADES – see (22)
Unless used very excessively in professional work, experience has shown it is not necessary during the life of the machine. Special hardened spiral gears require minimum lubrication. You can top up using Part number 43227 Grease Bottle purchased from your local Atom dealer, or any quality lithium based grease. Remove grease access screw on side of casing and apply 3 squeezes of the bottle. Do not use synthetic grease red or blue in colour.
All units when they leave the factory are fully filled with grease. Excessive grease when assembled or oil showing on the casing joint is normal. Gear box design ensures it will never be empty of lubrication.
Follow instructions on Atom packet.
Some early models have an additional small washer under nut and if this is not refitted then the blade cannot be tightened.
Only use genuine Atom blades.
If available, use an impact wrench for quick & easy replacement.
You are digging too deep. Use No 3 position on wheel height arm adjustment. Also, check blades are fitted correctly – see (22)
See ‘Easy to Edge Instructions’ above, (6).
Check power supply. Use correct industrial type lead, check if household earth leakage switch is working correctly. Throttle cable to switch on motor may require adjustment. Adjust throttle cable as follows –
ENSURE EDGER IS DISCONNECTED FROM POWER SUPPLY
1. Loosen 2 screws a little on side cover. (Do not remove cover)
2. Pull outer casing of black throttle cable outwards of handle
2 or 3mm and retighten 2 screws.
3. Plug in motor and check it switches on. If motor starts
without throttle trigger being pulled on, the outer cable
has been pulled too far out, readjust by sliding outer
cable in a little.
All small gasoline engine products vibrate a little.
Excessive vibration can be cause by –
1. Non-genuine blades fitted (out of balance). See (22)
2. Using non-genuine blades not designed for Atom Edgers. See (22)
(Also refer to 20 – When Should I Change my Atom Blades)
3. Loose or incorrectly installed clutch drum.
4. Worn or broken clutch shoes.
5. Broken motor housing.
6. Worn or overheated clutch assembly, see (6).
Action – Inspect all above carefully and replace and install correctly with new parts.
Retighten tines as follows. Ensure all washers are in place.
WARNING Incorrect assembly sequence on parts missing may cause blade system to lock up.
On production after December 2013, a grease filling screw is located under tine cover on the top of the body above tine shaft. Early models not fitted with filling access. A 5mm hole can be drilled through casing as shown towards centre and down towards shaft. Drill slowly about 20mm. This hole will allow grease to flow through to gear area. Us a suitable screw as a plug to seal hole.
33.1 Very hard or rocky ground – area to be cultivated should be broken up with a larger machine. The Atom Tiller is not designed for breaking up virgin ground.33.2 Using Tiller and not following instructions as follows
All tillers vibrate a little in use, more frequently in rough stony ground. Check that tines are not covered in plant material.
It is not necessary to use the second extension
tube or fish tail.
Use the blower as shown. When blowing and cleaning
up don’t loiter, keep moving forward as the Atom blower
is very powerful. Less weight – up to 1kg lighter when used
as illustrated due to its strong AIRLIFT® air blast, easier to use,
more convenient to handle, does the job quicker and easier
The Blower with vacuum attachment is only designed to pick up leaves and light, small litter.
It is not designed to pick up stones, pebbles, sticks, etc. These larger objects may damage fan blades and damage the unit.
See instructions in Blower Accessory Manual

|8. Problem||Broken pinion or crown gear teeth.|
|Cause||General overloading over a period of time. Blunt augers. Excessive powerful power head being used, eg. over 65cc.|
|Action||Replace gears and observe the “cause”. Use smaller power head.|
1. Sharpening Auger Bit with straight cutting edge.Use a small half round and flat one side file.
Snap the non-toothed end of the file with a pair of pliers or
in a vice. Secure the auger in a vice as close to the end as
possible. Only file the inside edges. Only use the end of the
file with short 13mm (1/2”) strokes. When the file end
becomes dull, break enough of to get a fresh filing edge.
If the correct sharpening procedure is followed the cutting
edges will be as sharp as your saw chain teeth. Once they
become dull they should be resharpened as described.
The best Wood Auger design is Atom Auger with 4 cutting edges as shown below.
2. Atom Wood Augers with exclusive Curved Cutting Edge Geometry.
1. Warranty three months from date of purchase.2. Augers are consumable items and cannot be expected to last forever.
2. If you do not know saw chain pitch, measure tips of two drive links of your saw chain (See fig 1) and check chain pitch fig 2. Download scale image at 100%.
3. To check whether chain is 3/8. or 3/8LP (low profile, Picco *) check cutting teeth height with gauge in fig 3.
