Page 4: Two Types Of Machines
Two types of machine cover most applications • Combined drill/breaker, Pionjär and PICO 14. Powered by a two-stroke engine with an integrated impact mechanism, the combined drill/breaker is equipped with rotation and air flushing mechanism for drilling applica- tions. The function selector allows you to switch between drilling and breaking/driving applications. - Page 5 • Heavy duty breaker, Cobra mk1. Also powered by a two-stroke engine, the Cobra mk1 has a separate im- pact mechanism activated by pressing the machine down. Thus, the engine can be run without engaging the impact mechanism. As powerful as a 27 kg (60 lbs) pneu- matic breaker, the Cobra mk1 is suitable for very de- manding breaking and driving jobs.

Page 6: Correct Fuel Mixture
Correct fuel mixture Use the correct fuel mixture, based on fresh fuel and oil. Pionjär 120/130 (1:12) ________ _____ Pionjär 140/150 (1:20) ________ _____ PICO 14 (1:25) _________________ _____ Cobra mk1 (1:50) ______________ _____ Cobra 149/248 (1:20) _________ _____ Too little oil in the mixture will result in insufficient lubri- cation and increased wear. - Page 7 Electrode gaps: Pionjär 1.5/0.060” ________________________ PICO 14 0.5/0.020” ______________________ Cobra mk1 0.5/0.020” ___________________ Cobra 149/248 1.5/0.060” ______________ Clean the air filter and housing daily. A clogged filter will cause excessive engine wear and carbonization which clogs up exhaust ports and channels. Never use the machine without the air filter.

Page 8: Safety First
Safety first For your own safety, always wear protective clothing – glasses, gloves, shoes or boots with steel toecaps, ear protectors and a hard hat. Hard hat Ear protectors Glasses Shoes or boots with steel toecaps Gloves For ease of operation use your thigh as support when running the machine. - Page 9 On the Pionjär shock-absorbent rubber bushings reduce vibration levels. The Cobra mk1 incorpo- rates H.A.P.S, (Hand and Arm Protection System), Atlas Copco’s unique anti vibration design. The leaf spring construction virtually eliminates vibrations. Avoid running the engine close to flammable material or in poorly ventilated areas.

Page 12: Cutting And Compacting Asphalt
Cutting and compacting asphalt For this job you need the asphalt chisel and tamper. Run the breaker at idling speed and make a score by hold- ing the machine at an angle. Break the asphalt, keeping the edge straight and angled slightly inwards. - Page 13 Compact the base thoroughly using the tamper. When packing new asphalt start at the edges. This will give a lasting seal. Compact the rest of the material and level off.
-
Page 14: Concrete Breaking
Concrete breaking Always start from the edge if possible when breaking concrete. Use the widest tool the material will allow. It makes the job go faster. To make an opening in a concrete wall, drill some holes around the outline of the hole and some additional holes in the middle. -
Page 15: Tie Tamping
Tie tamping The percussive effect provided by Atlas Copco breakers ensures perfect compaction of the bearing ballast, with- out risk of pulverization. Start upright and work your way under the tie. -
Page 16: Drilling
Drilling Atlas Copco offers an extensive range of drills for differ- ent materials and jobs. Avoid making a wider hole than necessary. Choosing the correct drill saves both time and energy. Integral drill steels are the best choice for hard materials. - Page 17 When collaring a hole, grip the side handle for better con- trol of the machine. Allow the engine to idle and press the machine and tool against the spot where you wish to drill. Increase the en- gine speed once the drill bit has collared a footing in the rock (or other material).
- Page 18 If rotation becomes sluggish due to a crack, or the drill keeps sticking, lift the machine a few times to improve flushing. If the tool gets stuck, stop the machine and free it with a drill wrench or a spanner. Drill dust in damp rock can cause the drill to stick.
- Page 19 Integral drill steel are grouped in series. When drilling a deep hole start with a short, wide drill and continue successively using the next size down. This avoids jam- ming and allows easy extraction. To get maximum effect, tools should be kept sharp and their shanks must have the correct lengths.

Page 20: Rock Splitting
Rock splitting Using a motorized drill/breaker, you can split large rocks safely and accurately. Start by drilling holes in a straight line across the rock you want to split. The holes should be about 30-40 cm (12”-16”) apart and at least 40 cm (16”) deep. Insert feathers and wedges along the line. -
Page 21: Anchoring
Anchoring For soil, special earth anchors are available for different loads. These are driven down with special driving rods. For anchoring jobs, in hard materials like rock or concrete, an expander bolt can be used. It can also be used to lift a rock or concrete slab. -
Page 22: Post Driving
Post driving A number of hammers are available for different profiles and tubes. When erecting a signpost, the first step is to drive down a short pipe. The sign is then placed inside the pipe and secured. Fencing Start the hole using the post hole tool. Use the driver pad to drive the fence post into the ground. -
Page 23: Digging
Digging Motorized breakers can be used to dig holes under ex- treme conditions. The round spade is ideal for digging in hard or frozen ground. -
Page 24: Accessories
Accessories An assortment of accessories to make your machine even more versatile. Fuel can. A practical 5 liter fuel can fits neatly in the transport case. Starter cord guides for Pionjär. Protects the starter cord and machine casings when starting the machine on driving rods, etc. - Page 25 Extra lower handle for Pionjär.
