Safety Precautions
Before Using the Chainsaw
•Read this manual carefully to understand how to operate this chainsaw properly.
•You should never use the chainsaw when you are under the influence of alcohol, when suffering from
exhaustion or lack of sleep, when suffering from drowsiness as a result of having taken cold medicine, or at
any other time when a possibility exists that your judgment might be impaired or that you might not be able
to operate the machine properly and in a safe manner.
•Avoid running the engine indoors. The exhaust gases contain harmful carbon monoxide.
•Never use the chainsaw under circumstances like those described below:
−When tile ground is slippery or when other conditions exist which might make it difficult to maintain a
steady posture.
−At night, at times of heavy fog, or at any other times when your field of vision might be limited and it
would be difficult to gain a clear view of the area.
−During rain storms, lightning storms, times of strong or gale-force winds, or at any other times when
weather conditions might make it unsafe to use the chainsaw.
•When using the chainsaw for the first time, before beginning actual work, learn how to properly handle it
from a skilled worker.
•Lack of sleep, tiredness, or physical exhaustion can result in lower attention spans, and this can lead to
accidents and injuries. Limit the amount of time of using the chainsaw continuously to somewhere around 10
minutes per session, and lake 10 – 20 minutes of rest between work sessions. Also try to keep the total
amount of work performed in a single day under 2 hours or less.
•Be sure to keep this manual handy so that you may refer to it later whenever any questions arise.
•Be sure to always include this manual when selling, lending, or transferring the ownership of the chainsaw.
•Never allow children or anyone unable to fully understand the directions given in this manual to use this
chainsaw.
Working Gears and Clothing
•When using the chainsaw, wear proper clothing and protective equipment as follows:
−Helmet
−Protective goggles/face protector
−Thick work gloves
−Non-slip sole work boots
−Ear protectors/mufflers
•And you should carry with you:
−Attached tools and files.
−Properly reserved fuel and chain oil.
−Things to give notice/attention to your work area (ropes, warning signs, etc.)
−Whistle (for collaboration or in case of emergencies).
−Hatchet or saw (for removal of obstacles).

•Never use the product when wearing pants with loose cuffs, when wearing sandals, or when barefooted.
Proper Handling of Fuel
•The engine of this chainsaw is designed to run on a mixed fuel which contains highly flammable gasoline.
Never store cans of fuel or refill the fuel tank in any place where there is a boiler stove, wood fire, electrical
sparks, welding sparks, or any other sources of heat or fire which might ignite the fuel.
•Smoking while operating the chainsaw or refilling its fuel tank is extremely dangerous! Always be sure to
keep lit cigarettes away from the chainsaw at all times.
•When refilling the tank, always turn off the engine first and take a careful look around your surroundings to
make sure that there are no sparks or open flames nearby before refuelling.
•If any fuel spillage occurs during refuelling, use a dry rag to wipe up spills before turning the engine back on
again.
•Alter refuelling, screw the fuel cap back tightly onto the fuel tank and then carry the product to a spot 3m or
more away from where it was refuelled before turning on the engine.
Before Starting the Engine
•Check your work area, the object/s to be cut and the cutting direction. Remove any visible obstacles in the
work area.
•Never start cutting until you have cleared your work area from any obstacles, secured your footing and
planned your retreat path from the falling tree/object.
•Exercise extreme caution and keep bystanders and animals away from the work area whose diameter is 2.5
times that of the cutting object.
•Inspect the machine for worn, loose, or damaged parts. Never operate the machine that is damaged,
improperly adjusted, or is not completely and securely assembled. Make sure that the saw chain stops
moving when the throttle control trigger is released.
When Starting the Engine
•Always hold the chainsaw firmly with both hands when the engine is running. Use a firm grip, with your
thumb and fingers encircling the handles.
•Keep all parts of your body away from the chainsaw when the engine is already running.
•Before starting the engine, make sure that the saw chain is not in contact with anything.
Operation
•Keep the handles dry, clean and free of oil or fuel mixture.
•Never touch the muffler, spark plug or other metallic parts of the engine while the engine is operating or
immediately after stopping the engine. Doing so could result in serious bums or electrical shock.
•Use extreme caution when cutting small size brush and saplings. Slender material may get caught in the
saw chain and be whipped toward you or pull you off-balance.
•When cutting a limb that is under tension, be alert for any spring backs so that you won’t be struck when the
tension in the wood fibres is released.
•Check the tree for any dead branches that could fall during the felling operation.
•Always turn the engine off first before setting the chainsaw down.

Kickback Safety Precautions
WARNING!
•Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and
pinch the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction,
kicking the guide bar up and back towards the operator. Either of these reactions may cause you to lose
control of the chainsaw, which could result in serious personal injury.
•Do not rely exclusively on the safety devices built into your chainsaw. As a chainsaw user, you should take
several steps to keep cutting jobs free from accidents and/or injuries.
−With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
−Keep a good grip on the chainsaw with both hands; with the right hand on the rear handle, and the left
hand on the front handle when the engine is running. Use a firm grip with thumbs and fingers encircling
the chainsaw handles. A firm grip will help you reduce kickback and maintain control of the chainsaw.
−Make certain that the area in which you are cutting is free from any obstructions. Do not let the nose of
the guide bar contact a log, branch, or any other obstructions which could get hit while you are operating
the chainsaw.
−Cut at high engine speeds.
−Do not overreach or cut above shoulder height.
−Follow the manufacturer’s sharpening and maintenance instructions for the saw chain.
−Only use replacement bars and chains specified by the manufacturer or the equivalent.
Maintenance
•In order to maintain your chainsaw in proper working order, perform the maintenance and checking
operations described in the manual at regular intervals.
•Always be sure to turn off the engine before performing any maintenance or checking procedures.
WARNING!
The metallic parts can reach high temperatures immediately after stopping the engine.
•Leave all maintenance other than the items listed in this manual to an authorised service centre or
personnel.
Transportation
Always carry the unit with the engine stopped, the guide bar covered with the protector to the rear, and the
muffler away from your body.
