5.  Depress the trigger release. Squeeze and release 

the throttle trigger to let the engine idle. Before 
accelerating the engine or cutting wood, make sure 
the chain brake is in the "run" position by pulling back 
on the brake lever/hand guard.

STOPPING THE ENGINE
See Figures 7 and 14.

Release the throttle trigger and let the engine return to 
idle. To stop the engine, move the ignition switch to the 

stop

 (0) position. Do not put the chainsaw on the ground 

while the saw chain is still moving. For additional safety, 
set the chain brake when the saw is not in use.
In the event that the ignition switch will not stop the saw, 
pull the choke lever out to the fully extended position 

(Full Choke)

 and engage the chain brake to stop the 

engine. If the ignition switch will not stop the saw when 
set to the 

stop

 position, have the ignition switch repaired 

before using the chainsaw again to prevent unsafe 
conditions or serious injury.

Note:

 When you are finished using the saw, always 

relieve tank pressure by loosening, then retightening, the 
chain lubricant and fuel caps. Allow the engine to cool 
before storing.

PULL AND PUSH
See Figure 15.

The reaction force of the saw is always opposite to the 
direction the chain is moving. Thus, the operator must 
be ready to control the PULL when cutting on the bottom 
edge of the bar and the PUSH when cutting along the 
top edge.

Note: 

The chainsaw has been fully factory tested. It is 

normal to find some slight lubricant residue on the saw.

KICKBACK PRECAUTIONS
See Figures 17, 22.

Rotational kickback occurs when the moving chain 
contacts an object at the Kickback Danger Zone of the 
guide bar. The result is a lightning-fast reverse reaction, 
which kicks the guide bar up and back towards the 
operator. This reaction can cause loss of control, which 
can result in serious injury.

PREPARING FOR CUTTING 

PROPER GRIP ON HANDLES
See Figure 18.

See 

General Safety Rules 

for appropriate safety 

equipment.

„

  Wear non-slip gloves for maximum grip and 

protection.

„

  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.

„

  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 19

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 20.

„

  Balance your weight with both feet on solid ground.

„

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

position to withstand any kickback force.

„

  Keep your body to the left of the chain line.

„

  Keep your thumb on the underside of the handlebar.

WORK AREA PRECAUTIONS
See Figure 21.

„

 Cut 

only wood

 or materials made from wood.

„

  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.

„

  Keep helpers, bystanders, children, and animals, 

SAFE DISTANCE

 from the cutting area. During 

felling operations, the safe distance should be at least 
twice the height of the largest trees in the felling area. 
During bucking operations, keep a minimum distance 
of 5 metres between workers.

„

  Always cut with both feet on solid ground to prevent 

being pulled off balance.

„

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

difficult to control against kickback forces.

„

  Do not fell trees near electrical wires or buildings. 

Leave this operation for professionals.

„

  Cut only when visibility and light are adequate for you 

to see clearly.
