SAFETY INFORMATION KICKBACK (See Figure 1-2) W A R N I N G Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant.
SAFETY INFORMATION where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge. (See Figure 3) PULL Fig. 3 PUSH UNDERSTANDING YOUR CHAIN SAW SAFETY DEVICES (See Figure 4) Fig.

OPERATING YOUR CHAIN SAW FELLING TREES HAZARDOUS CONDITIONS W A R N I N G Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible VHULRXV LQMXU\ ...
Page 21
OPERATING YOUR CHAIN SAW PROPER PROCEDURE FOR TREE FELLING (See Figure 12-15) Felling a tree — When bucking and felling operations are being performed by two or more persons, at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled.
Page 22
OPERATING YOUR CHAIN SAW NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (ap- proximately 2" (5 cm) or 1/10 the diameter of the tree). This is called “hinge” or “hingewood.” It controls the fall of the tree and prevents slipping or twisting or shoot back of the tree off the stump.
OPERATING YOUR CHAIN SAW (See Figure 16) REMOVING BUTTRESS ROOTS A buttress root is a large root extending from the trunk of the tree above the ground. Remove vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling procedure as stated in Proper Procedure For Tree Felling after you have removed the large buttress roots.
Page 24
OPERATING YOUR CHAIN SAW (See Figure 18) BUCKING WITH A WEDGE If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching. (See Figure 19) BUCKING LOGS UNDER STRESS When the log is supported on one end, cut 1/3 the diameter from the underside.

OPERATING YOUR CHAIN SAW When bucking on a slope always stand on the uphill side of the log. when cutting through to maintain complete control release the cutting pressure near the end of the cut without relaxing your grip on the chainsaw handle.
BATTERY CHARGER CHARGING PROCEDURE ( See Figure 11. NOTE: The battery is not shipped fully charged. It is recommended to fully charge before first use to ensure that maximum run time can be achieved. This lithium-ion battery will not develop a memory and may be charged at any time.
Page 28
BATTERY CHARGER W A R N I N G If the battery is inserted into the charger when warm or hot, the CHARGING LED indicator light on the charger may switch on and illuminate ORANGE. If this occurs allow the battery to cool outside of the charger for approximately 30 minutes.
MAINTENANCE W A R N I N G When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. W A R N I N G Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust.
Page 30
MAINTENANCE C A U T I O N Always wear gloves when handling the bar and chain; these components are sharp and may contain burrs. W A R N I N G Never touch or adjust the chain while the motor is running. The saw chain is very sharp; always wear protective gloves when performing maintenance to the chain to avoid possible serious lacerations.

MAINTENANCE CHAIN MAINTENANCE (See Figure 37) Use only a low-kickback chain on this saw. This fast-cutting chain provides kickback reduction when properly maintained. For smooth and fast cutting, maintain the chain properly. The chain requires sharpening when the wood chips are small and powdery, the chain must be forced through the wood during cutting, or the chain cuts to one side.
