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.
Do not use ethanol based fuel as it can absorb water if not used within a short period. Use any petrol/gasoline other than ethanol based fuels. Ethanol can also affect fuel lines (shrink) or harden or soften engine and carby gaskets. Worn, split, stiff or leaking fuel lines to be replaced immediately.
What about using fuel modifiers? Currently we do not have information or experience using these products.
Use quality 2 stroke oil sold as 50/1 grade, available from service dealers or large hardware stores with built in measure.
If you happen to make a 25 or 30 to 1 mix, it is ok to use, but continuous use will carbonise the spark plugs, and exhaust. Many manufacturers recommend this mix for first few hours of operation to run motor in.
The best mix for hot Australian conditions is 40:1 using quality grade 2 stroke oil (sold as 50:1 grade).
Measure amounts for 40:1 is 100ml oil for four litres of petrol, or 25ml oil for one litre of petrol.
Always use a funnel or pouring nozzle on container 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.
If fuel is left in the petrol tank for long periods it could become thick, sticky and clog up fuel filters, lines and carburettor components. Long term non-use can cause certain fuels to react with metals, eg. brass in carburettors or filters.
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.
Clean and oil the air filter regularly according to use
Use quality non-ethanol based gasoline 40:1 mix for 2 stroke engine (using 50:1 grade
2-stroke oil), 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.
|How to adjust jets of Carburettor|
|Some engines do not have jet adjustment. Check all above. Other reasons for unstable running are –1. Cylinder base gasket leaking.2. Manifold cracked or broken.3. Manifold gaskets or O-rings (eg Honda GX 25 & 35 ) require replacing.4. Leaking oil seals.|
|A pressure test of motor at 5 PSI will show these faults.|
|Engines with jet adjustment|
|Some engines require factory adjustment type screwdriver – All Atom 26cc engines us P/N 63627.
Some engines no tools available – a rough fix on some carburretors is to use a fine blade and cut through the carby body and through the jet screw to form a slot.
|How to adjust –1. Screw carby idle adjustment screw in a little (for faster idle).2. Screw both jets in ‘right hand’ rotation until closed. Do not overtighten.3. Adjust both jets out (low & high speed) ‘left hand rotation’ until 1¼ turns out.4. Prime motor (10 pumps on primer) to ensure air bubbles are out of line.5. If cold, push choke on and crank engine until it starts. If motor hot, choke may not be required.
6. Increase high speed jet up and down (richer mix) close (leaner mix) to gain peak revolutions. Allow speed to drop back to idle and readjust carby idle adjustment screw to lower or increase speed. On pulling trigger if motor hesitates, increase low speed jet a little until it responds to smooth acceleration.
At high speeds and engine is rough running, turn high speed jet in a little
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.
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. On current models, a small 3mm vent hole on each side of casing above gear box may show oil grease normal condition, overflow of excess grease. 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 switch is on .
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 caused 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.
and force out a great amount of air.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
DRILL UNITS & WOOD AUGERS

|4. Problem||Too much oil on chain.|
|Action||Re-adjust oiler on chain saw or use heavier grade oil if no oil adjuster|
|5. Problem||Chain wear|
|Cause||Not enough oil on chain. Wrong oil, do not use sump oil.|
|Action||Use quality chain saw oil.|
|6. Problem||Auger will not turn at all.|
|Cause||Not enough power in chainsaw. Check carby adjustment tune motor. Blunt auger or worn out, not cleaning hole of wood chips by reversing and cleaning holes every 50mm or less.|
|Action||Sharpen auger or replace.|
|7. Problem||Breaking safety pins (drill attachment).|
|Cause||Overloading, Auger-Stop adjustment not set correctly or tampered with. Locked off.|
|Action||Check size of power head, sharpness and type of auger. See also (2) above. Use correct Pin, P/N 40907 “UNBRAKO BRAND” 3/16” x ½”|
|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 edge. 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 two cutting edges as shown below.
2. Atom Wood Augers with exclusive Curved Cutting Edge Geometry.
3. Sharpening Auger Bits with Rounded Edge.
Use a small 3/16” (4.5-5mm) round file. Snap end off in a vice. Secure auger end in vice and carefully file inner side of cutting edge as shown in illustration above. Follow contour of rounded inner shape. Do not file outside edge. The outer inside corner of the cutter is filed as you would file a saw chain. With very small augers, eg. 3/8” (10mm) use a smaller 4mm round file.
1. Warranty three months from date of purchase.
2. Augers are consumable items and cannot be expected to last forever.
3. Augers not guaranteed if used in hydraulic drills, very high powered Electric drills or on Chainsaw Drills attachments fitted with 70cc or larger chainsaw power heads.
