Installing Guide Bar and Saw Chain :

  1. Loosen the nuts and remove the chain cover.
  2. Gear the chain to the sprocket and, while fitting the saw chain around the guide bar, mount the guide bar to the power unit. Adjust the position of the chain tensioner.
  3. Fit the chain cover to the power unit and fasten the nuts to finger tightness.
  4. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until the tie straps just touch the bottom side of the bar rail.
  5. Tighten the nuts securely with the bar tip held up. Then check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose.
  6. Tighten the screw.

Assembling Procedure :

  1. Lay the parts of the electric chain saw out flat. Place the chain on a flat surface as if it were wrapped around on the chain saw guide bar.
  2. Turn the adjustment screw on the front of the chain saw body counterclockwise with a flat-head screwdriver. The adjustment screw is near the guide bar bolts; the block resembles a collar on the screw. Turn the screw until the adjustment block on its end is at the rear of the adjusting plate. The screw attaches through the plate.
  3. Insert the rear of the guide bar between the adjusting plate and the sprocket support plate. The sprocket support plate covers the sprocket and extends past the guide bar mounting bolts. The rear of the guide bar has the slot in the center and a hole below the slot. The adjustment block must sit in the hole on the guide bar.
  4. Thread the guide bar securing nuts over the bolts until they are finger-tight. Place the chain around the sprocket and over the top of the guide bar, with the cutting edge of the chain pointing forward. Wrap the chain around the front of the guide bar and underneath it.
  5. Rotate the adjustment screw clockwise with the screwdriver to remove slack from the chain. Continue turning the screw until the chain is tight under the bottom of the chain guide bar. Tighten the guide bar nuts securely with a socket wrench.
  6. Place the side cover over the chain saw. Press until it snaps into position.



When limbing thick branches, the guide bar may get pinched easily. Branches under tension often snap up, so cut troublesome branches in small steps. Apply the same principles as for cross cutting. Think ahead and be aware of the possibilities consequences of all
your actions.


Before starting to cut through the log, try to imagine what is going to happen. Look out for stresses in the log and cut through it in such a manner that the guide bar will not get pinched.


Take a firm stance. Begin with an upper cut. Donot cut too deeply, about 1/3 of the log diameter is enough. Finish with a bottom cut. The saw cuts should meet.


Begin by cutting on the opposite side of the log. Pull the saw towards you, followed by previous procedure. Make a boring cut if the log is close to the ground.


Stop the machine immediately and raise the log or change the position, using a thick branch or pole as a lever. Do not try to pull the saw free. If you do, you can deform the handle or be injured by the saw chain if the saw is suddenly released.


  1. In all circumstances the operation of the chain saw is a one man job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well. After you have learned the basic techniques of using the saw, your best aid will be your own good common sense...
  2. The accepted way to hold the saw is to stand to the left of the saw with your left hand on the front handlebar and your right hand on the rear handle so you can operate the throttle trigger with your right index finger.
  3. Before attempting to fell a tree, cut some small logs or limbs. Become thoroughly familiar with the controls and the responses of the saw.
  4. Start the machine, see that it is running properly. Squeeze the trigger to open the throttle wide open and start the cut. If the chain is properly sharpened, the cutting should be relatively effortless. It is not necessary to press down hard to make the saw cut. Pushing the saw too hard will slow the motor speed and cutting will actually be more difficult.
  5. Wear suitable hearing protective device such as ear muffs or ear plugs to protect against objectionable or uncomfortable loud noises.


  1. First and foremost, be aware of the dangers of "kick back", which is the leading cause of chainsaw injury. Always avoid touching the tip of the guide bar to any surface, as this will tend to throw the nose of the saw back towards the user. Also, do not hold the saw so it is lined up with your centerline,
  2. always hold it off to your right side so it will miss your face if it kicks back. Special "low kickback" chains are available to reduce the risk also.
  3. Do not operate a chainsaw without all recommended safety items. Gloves, eye protection, hearing protection, and long sleeve shirts and long pants are minimum. New saws often come with a hard hat, also, to protect from falling debris or limbs.
  4. Chainsaw safety chaps are strongly encouraged. These are constructed from nylon, kevlar, or fiberglass and designed to instantly stop and jam the saw if it contacts your leg. These can be found locally, or with a simple internet search for around $50.00 or sometimes even less.
  5. Store fuel and lubricants in approved containers, away from the cutting area.
  6. If you are unable to have someone watch for safety while you cut, consider waiting until someone is available, or at least let someone know what you are doing, where you are at, and when you are finished. One slip with a running saw can be fatal.
  7. Never operate a saw that isn't in good working condition. The kick-back brake, chain guard, and other safety features are for your protection. Use a saw big enough for the job. Cutting half the diameter of a log doubles the chances of kickback.
  8. Each type of cut mentioned at the beginning of this article has unique dangers and approaches. Space just doesn't allow for covering them all in sufficient detail, so if in doubt, ask! Protect against objectionable or uncomfortable loud noises.


  1. Random use of a chainsaw is easy, but quality cuts and accuracy take knowledge and experience. It is not advised that you fell or limb a tree of any size greater than 15 feet with out some professional involvement (it also happens to require a contractors license in many states-be sure to check the laws in your respective state)
  2. Keep the blade of the saw sharp and well oiled and never let it come in contact with metal or the ground. The blade simply is not designed to cut these materials and will become dull and useless immediately.
  3. Cutting roots or dirty wood also will rapidly dull a saw chain, if you do this often, carbide toothed chains are available...but theyre expensive! The key is to touch up the cutters often with a file guide...say every time you stop to refuel. If you let the cutters get very dull, it will take a lot of time and elbow grease to get the sharp edges back. Anytime you feel the need to push down while cutting, its time to sharpen. The saw should feed itself into the cut with very little effort.
  4. Bring tools to the work site for adjusting the blade. A new saw chain will usually become loose after just a few minutes of use as it "breaks in" to the bar. Keeping the chain tight, but not too tight, will provide a cleaner, faster cut with less chance of chain throw off.


This brake can be operated manually with the front guard turned down to the guide bar. To release brake, pull up the front towrd the front handle till "click" sound is heard.


  • Be sure to confirm brake operation on the dialy inspection.
  • In case, the brake is not effective, ask our dealer inspection and repairing. The engine, if being kept rotated at high speed with the brake engaged, heats the clutch, causing a troublr. When the brake is operated while in operation, immediately release your fingers from the throttle lever and keep the engine idling.


  • When using Zenoah genuine 2-Cycle oil (FC Grade): 50:1 (100ml of oil for every 5 litres of gasoline).
  • When using commercially available 2-Cycle oil(FB Grade): 25:1(100ml of oil for every 4 litres of gasoline)


  1. Fill fuel and chain oil tanks repsectively and tighten the caps securely..
  2. Put the switch to "I" position.
  3. Pull out the choke knob to the closed. Note: When restarting immediately after stopping the engine, leave the choke knob at the open position.
  4. While holding the saw unit securely on the ground, Pull the starter rope vigorously.
  5. When engine has ignited first, pull the throttle lever slightly to return the choke knob to the open position and pull the starter again to strt the engine.
  6. Allow the engine to warm up with the throttle lever pulled slightly. At once pulling throttle lever out, the choke knob is automatically returned to the operating position.

Checking Oil Supply:

After starting the engine, run the chain at medium speed and see if chain oil is scattered off.
1.Chain Oil: The chain oil flow can be changed by inserting a screw driver in the hole on bottom of the clutch side. Adjust according to your work conditions.
2.Adjusting Carburetor: The Carburetor onb your unit has been factory adjusted, but may require fine tuning due to change in operating conditions. Before adjusting the carburetor, make sure that provided are clean air/fuel filters and free, properly mixed fuel.

When adjusting, take th following steps,

Be sure to adjust the carburetor with the bar chain attached.

  1. Stop engine and screw in both H and L needle until they stop. Never force. Then set them back the initial number of turns.
  2. Start engine and allow it to warm up at half-throttle.
  3. Turn L needle slowlyc.clockwise to find a position where idling speed is maximum, then set the needle back a quarter (1/4) turn counter clockwise.
  4. Turn idle adjusting screw (T) Counter clockwise so that saw chain does not turn. Idling speed is too slow, turn the screw clockwise.
  5. Make a test cut and adjust the H needle for best cutting power, not for maximum speed.


  1. Clean the Petrol Chain saw regularly with a clean rag. The handles, in particular, must be kept free of oil.
  2. Have any damage to the plastic housing repaired properly and immediately.
  3. Do not use the saw i the switch is not working properly.
  4. Under no circumstances should any modifications be made to the chain saw, please get the tool chekced or replaced only at the CUMI authorized service centre.
  5. Inspect the tool regularly for loose screws and repalce.tighten them periodically.
  6. Replace if adhered part is peeled or crack is observed on the rubber part.
  7. Sprocket: Check for crack and for excessive wear interfring with the chain drive. If the waering is found obviously, replace it with new one. Never fit a new chain on a worn sprocket, or a worn chain on an new sprocket.
  8. Cylinder Fins: Dust clogging between the cyclinder fins will cuase overheating of the engine. Periodically check and clean the cyclinder fins after removing the air cleaner and cylinder cover. When installing the cylinder cover, make sure that switch wires and grommets are positioned correctly in place.
