OPERATION
PREPARING FOR CUTTING
PROPER CLOTHING FOR SAFETY (Fig. 16)
■
Wear loose-fitting clothing ( A ). Always wear heavy,
long trousers ( B ), boots ( C ), and gloves ( D ). Do not
wear jewellery, shorts, sandals, or go barefoot. Do not
wear loose fitting clothing, which could be drawn into
the engine or catch the chain or undergrowth.
Wear overalls, jeans, or leggings made of cut-resistant
material or ones that contain cut-resistant inserts.
Secure hair so that it is above shoulder level.
■
Wear non-slip safety footwear and heavy-duty gloves
to improve your grip and to protect your hands.
■
Wear eye ( E ), hearing ( F ), and head ( G ) protection
when operating this equipment.
PROPER GRIP ON HANDLES (Fig. 17 & 18)
Refer to “Specific Safety Rules – Proper Clothing
For Safety” earlier in this manual 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 be wrapped under the
handlebar. This grip is least likely to be broken
(by a kick-back 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.
PUSH AND PULL (Fig. 19)
The reaction force is always opposite to the direction the
chain is moving. Thus, the operator must be ready
to control the PULL ( A ) when cutting on the bottom edge of
the bar and the PUSH (
B
) when cutting along the top edge.
NOTE: Your chainsaw has been fully factory tested.
It is normal to find some slight oil residue on the saw.
PROPER CUTTING STANCE (Fig. 20)
■
Balance your weight with both feet on solid ground.
■
Keep left arm with elbow locked in a “straight arm”
position ( B ) to withstand any kick-back force.
■
Keep your body to the left of the chain line (
A
).
■
Keep your thumb on underside of handlebar ( C ).
BASIC OPERATING/CUTTING PROCEDURES
Practise cutting a few small logs using the following
technique to get the “feel” of using your saw before you
begin a major sawing operation.
1. Take the proper stance in front of the wood with the
saw idling.
2. Accelerate the engine to full throttle just before
entering the cut by squeezing the throttle trigger.
3. Begin cutting with the saw against the log.
4. Keep the engine at full throttle the entire time you
are cutting.
5. 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.
6. 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 may result in
unnecessary wear to the chain, bar, and engine.
7. Do not put pressure on the saw at the end of the cut.
