English (Original Instructions)

n

  Hold the saw firmly with both hands. Always keep 

your left hand on the front handle and your right hand 

on the rear handle so that your body is to the left of 

the chain line.

WARNING:

Never use a left-handed (cross-handed) grip or 

any stance that would place your body or arm 

across the chain line.

n

  Maintain a proper grip on the saw whenever the 

engine is running. The fingers should encircle 

the handle and the thumb is wrapped under the 

handlebar. This grip is least likely to be broken by a 

kickback or other sudden reaction of the saw. Any 

grip in which the thumb and fingers are on the same 

side of the handle is dangerous because a slight kick 

of the saw can cause loss of control.

WARNING:

See Figure 20

DO NOT operate the throttle trigger with your left 

hand and hold the front handle with your right 

hand. Never allow any part of your body to be in 

the chain line while operating a saw. 

PROPER CUTTING STANCE

See Figure 21.

n

  Balance your weight with both feet on solid ground.

n

  Keep left arm with elbow locked in a “straight arm” 

position to withstand any kickback force.

n

  Keep your body to the left of the chain line.

n

  Keep your thumb on underside of handlebar.

WORK AREA PRECAUTIONS

See Figure 22.

n

 Cut 

only wood

 or materials made from wood

n

  Never allow children to operate the saw. Do not Allow 

persons to use this chainsaw who have not read this 

operator’s manual or received adequate instructions 

for the safe and proper use of this chainsaw.

n

  Keep helpers, bystanders, children, and animals, 

SAFE DISTANCE

 from the cutting area. During 

felling operations, the safe distance should be a least 

twice the height of the largest trees in the felling area. 

During bucking operations, keep a minimum distance 

of 5 metres between workers.

n

  Always cut with both feet on solid ground to prevent 

being pulled off balance.

n

  Do not cut above chest height as a saw held higher is 

difficult to control against kickback forces.

n

  Do not fell trees near electrical wires or buildings. 

Leave this operation for professionals.

n

  Cut only when visibility and light are adequate for you 

to see clearly.

BASIC OPERATING/CUTTING PROCEDURES

It is strongly suggested that you seek professional 

training in the safety and use of this tool.

Practice cutting a few small logs on a saw-horse or cradle 

using the following technique to get the “feel” of using the 

saw before you begin a major sawing operation. 

n

  Take the proper stance in front of the wood with the 

saw idling.

n

  Accelerate the engine to full throttle just before 

entering the cut by squeezing the throttle trigger.

n

  Begin cutting with the saw against the log.

n

  Keep the engine at full throttle the entire time you are 

cutting.

n

  Allow the chain to cut for you; exert only light 

downward pressure. Forcing the cut could result in 

damage to the bar, chain, or engine.

n

  Release the throttle trigger as soon as the cut is 

completed allowing the engine to idle. Running the 

saw at full throttle without a cutting load can result in 

unnecessary wear to the chain, bar, and engine.

n

  Do not put pressure on the saw at the end of the 

cut as this may cause the saw to drop in an unsafe 

manner.

FELLING TREES IN HAZARDOUS CONDITIONS

WARNING:

Do not fell trees during periods of high wind or 

heavy rain. Wait until the hazardous weather 

has ended. When felling a tree, it is important 

that you heed the following warnings to prevent 

possible serious injury.

n

  Do not cut down trees having extreme lean or large 

trees with rotten limbs, loose bark, or hollow trunks. 

Have these trees pushed or dragged down with 

heavy equipment, then cut them up.

n

  Do not cut trees near electrical wires or buildings.

n

  Check the tree for damaged or dead branches that 

could fall and hit you during felling.

n

  Periodically glance at the top of the tree during the 

back cut to assure the tree is going to fall in the 

desired direction.

n

  If the tree starts to fall in the wrong direction, or if the 

saw gets caught or hung up during the fall, leave the 

saw and save yourself!

PROPER PROCEDURE FOR TREE FELLING

See Figures 23 - 26.

n

  Pick your escape route (or routes in case the 

intended route is blocked). Clear the immediate 

area around the tree and make sure there are no 

obstructions in your planned path of retreat. Clear 

the path of safe retreat approximately 135° from the 

planned line of fall.

n

  Consider the force and direction of the wind, the lean 

and balance of the tree, and the location of large
