Step 1 After taking all parts out of the carton, turn the cardboard box over and rest the engine on top of it for ease of assembly. Step 3 Insert the bolt through the right handle (with the throttle trigger) and through the main body of the Edger with the point of the plastic washer facing down towards the blades. 8 Step 2 Slip the flat handle clamp (key #48) onto the long bolt (key #52) so that the hex head fits into the recessed area.
Step 5 Place the handle cross brace (key #46) between the handles and lay the throttle cable and wire into the clips of the righthand handle brace. Step 6 Line up the holes in the brace with the holes in the handle tubing and attach the brace with one screw (key #1) and one nut (key #2) on each side. Step 7 Holding the nut in place, tighten the screw on each side with a flat head screwdriver.
Fuel Mix and Fueling Your Mantis Edger is powered by a two-stroke, air cooled engine which requires a fuel mixture of gasoline and two-cycle oil. Use a mixture of 50 parts unleaded regular gasoline and 1 part two-cycle oil (50:1). Use branded 89 octane (R+M+2) unleaded gasoline or gasohol (max. 10% ethyl alcohol, or 15% MTBE, no methyl alcohol). ! ▲ WARNING • DANGER ! ▲ FUEL IS EXTREMELY FLAMMABLE. HANDLE IT WITH CARE. KEEP AWAY FROM IGNITION SOURCES. DO NOT SMOKE WHILE FUELING YOUR EQUIPMENT.
Starting Instructions Picture 1 To Start Your Mantis Edger for the First Time: Fill the fuel tank with the proper oil/gasoline mixture (see previous section). Hand tighten the gasoline cap until it’s just snug. Place the start/stop switch into the “start” position (Picture 1). Lay the Edger flat on the ground for the following steps. Picture 2 Pull out the choke button to close the engine choke (Picture 2). Locate the purge bulb on the upper right of the engine, in front of the fuel tank (Picture 3).
Starting Instructions ...continued... Starting a Warm Engine Slide start/stop switch to the START position. Push choke button into the RUN (open) position. If there is no fuel in the clear return line, push primer bulb 3-4 times or until fuel is visible in the line. Pull starter rope using short pulls, 1/2 to 2/3 of the rope length. If engine fails to start in 4 pulls, use “First Time” starting procedure on page 11.
What To Do Just In Case If you follow the normal starting procedure, you should have no problem starting your edger. But, just in case you do have problems, here’s what to do. Make sure the start/stop switch is on “start.” You’d be surprised how many people forget to slide the switch into the “start” position. Picture 1 If the switch was on “stop” when you pulled the cord, you may have flooded the engine. Starting a Flooded Engine • First, examine the spark plug.
What To Do Just In Case ...continued... Here’s Another Way to Start Your Mantis Edger 7. If the engine still does not start, repeat steps 2 through 6. If you follow the previous steps and your engine still won’t start, try this: 8. If the engine still does not start, call your local authorized Mantis Dealer. 1. Slide the switch to “start.” 2. Push the choke button to open the choke. 3. Press the plastic bubble 5 to 6 times. 4. Give the starter cord a few short, quick pulls.
As cutting actions begins, push the Mantis Edger forward so that the blade can cut the edge as you move forward. (Picture 4). Continue at a moderate pace until you are familiar with the controls and the handling of the Mantis Edger. If blade jams or stops in the ground, lower handles or pull back unit and recommence (Picture 5). Control engine and cutting speed to suit work being done When cutting efficiently, engine speed should be full throttle under load.
Blade Replacement Picture 1 1. Stop engine. Unplug the spark plug wire. Clean area around dust cover and pry debris out with a screwdriver (Picture 1). 2. Through dust cover, place 14mm or 9/16” socket wrench. On blade end of shaft, place 18mm or adjustable wrench on blade nut (Picture 2). 3. Unscrew nut counter-clockwise (normal right hand thread). Picture 2 4. Remove one small washer, one large washer and two blades (Picture 3). Before installing blade and washers, clean all grit and grease.
Maintenance Check the Air Filter Often A wet or dirty air filter can affect the way your engine starts, performs, and wears. So, it’s a good idea to check your air filter at least once a month. If you work in dusty soil, or if you want to be on the safe side - then check your filter more often (for instance, before each use). But be sure to replace it at least once a year, in the spring or fall. Clean or change it as needed. It is recommended to change the air filter yearly.
Maintenance ...continued... Clear Blockages From the Fuel Line and Filter After you’ve used your Edger for a few seasons, check for blockages in the fuel tank and fuel filter. Such blockages can keep your Edger from starting. Picture 1 Clear any blockages you see in the tank, fuel filter, or fuel line. Remember: The fuel filter is located inside the tank (Picture 1). Then, use the normal starting procedure to start your Edger. What To Do If Your Engine Idles Too High What if your engine runs too fast...
Maintenance ...continued... What To Do If Your Engine Runs “Rough” If your engine runs “rough” or stalls, you may need to adjust the carburetor and idle screws. If you remove the air-cleaner cover, you’ll see the two carburetor adjustment screws, next to the black choke button. The “RED” screw is the HIGH-speed adjustment...The “WHITE” screw is the low speed adjustment. Start the engine and let it run for two to three minutes.
Storage ! ▲ WARNING ! ▲ DO NOT STORE IN AN AREA WHERE FUEL FUMES MAY ACCUMULATE AND REACH A FLAME OR SPARK Each fall - or before you store your Mantis Edger for any long period - be sure to take these measures: 1. Do not store your Edger with fuel still in it. Even under ideal conditions, stored fuel containing ethanol or MTBE can start to go stale in 30 days. And, since stale fuel has a high gum content, it can clog the carburetor, which will, in turn, restrict fuel flow.
Storage ...continued... 10. Order new parts to replace any that are badly worn or broken. Just contact your local authorized Mantis dealer. But do it early, so you’ll have the parts well before the next season. 11. Store your Edger - in an upright position - in a clean, dry place (Picture 1, previous page). 12. Do you have any fuel left over from last season? Dispose of it properly. Buy fresh oil and gasoline next season.
Troubleshooting Tips Problem Engine fails to start Engine hard to start. Cause Start/Stop switch is in Stop position. No fuel in tank. Fuel strainer clogged. Fuel line clogged. Spark plug shorted or fouled. Spark plug is broken (cracked porcelain or electrodes broken) Ignition lead wire shorted, broken or disconnected from spark plug. Ignition inoperative. Move switch to start. Water in gasoline or stale fuel mixture. Too much oil in fuel mixture. Drain entire system and refill with fresh fuel.
Troubleshooting Tips Problem Engine lacks power. Cause Air filter clogged. Carburetor out of adjustment. Muffler clogged. Clogged exhaust ports. Spark Arrestor clogged. Poor compression. Engine noisy or knocking. Spark plugs in incorrect heat range. Bearings, piston ring or cylinder walls are worn. ...continued... Solution Clean or replace air filter. See “Carburetor Adjustment.” Clean carbon from muffler. Remove muffler, rotate engine until the piston is at top of cylinder.
