• IMPORTANT SAFETY INSTRUCTIONS •
READ ALL INSTRUCTIONS BEFORE OPERATING
WARNING:
When using this unit, basic safety precautions should always be
followed to reduce the risk of property damage and personal injury, including the following:
CALIFORNIA PROPOSITION 65
WARNING:
Engine exhaust, some of its constituents and certain finished

BASIC SAFETY PRECAUTIONS
• DO NOT rely exclusively upon the safety devices built into the unit.
• DO NOT allow the unit to be used as a toy.
• Please read the entire operator's manual carefully before attempting to assemble, operate or
maintain the unit.
• Follow all safety instructions. Failure to do so can result in property damage or serious injury to
yourself and/or others.
• Be thoroughly familiar with the controls and the proper use of the unit. Know how to stop the unit
and disengage the controls quickly.
• Stay alert! Do not operate the unit when tired, ill or under the influence of alcohol, drugs or medication.
• Never allow children to operate the unit. Never allow adults to operate the unit without proper instruction.
• Make sure that all guards and safety attachments are properly installed before operating the unit.
• Keep these instructions. Refer to them often and use them to instruct other users. If loaning
someone this unit, also loan them these instructions.
• Keep bystanders, especially children and pets, at least 50 feet (15 m) away. If anyone enters the
work area, stop the unit!
• Keep the work area clean. Cluttered areas invite injuries. Do not start cutting until the work area is clear
and free from obstructions, there is secure footing and a planned retreat path from falling branches.
• Always wear appropriate eye and ear/hearing protection when operating this unit. Wear safety
goggles, or safety glasses with side shields, that are marked as meeting ANSI Z87.1-1989
standards. Failure to do so could result in serious eye injury caused by thrown or falling objects. If
the operation is dusty, wear a face mask or dust mask. Use a hard hat or other type of safety helmet.
• Dress appropriately, wear heavy, snug-fitting clothes (long pants and a long sleeve shirt), non-slip
protective gloves and steel-toed safety boots. Do not wear loose clothing, jewelry, short pants,
sandals or go barefoot. Secure hair above shoulder level to prevent entanglement in moving parts.
• Only use the unit in daylight or good artificial light.
• Only use the unit for its intended purpose: to cut wood. Only use the unit as described in this
manual. Only use the manufacturer's recommended attachments with this unit.
UNDERSTANDING KICKBACK
DANGER:
Kickback may occur when the nose or tip of the guide bar touches an
object, or when the wood closes in and pinches the saw chain in the cut. In some cases, tip
contact may cause a lightening-fast reverse action, kicking the guide bar rapidly back towards
the operator. Pinching the saw chain along the top of the guide bar may push the guide bar
rapidly back towards the operator. Either of these reactions may cause a loss of control over the
saw, which could result in serious injury to the user. Contact with foreign objects within the wood
can also induce a loss of chain saw control.
• Rotational Kickback can happen when the upper tip of
the guide bar contacts an object while the chain is
moving (Fig. 1 & 2). This can cause the chain to dig into
the object and momentarily stop moving. The guide bar
is then kicked up and back toward the operator in a
lightning-fast reverse reaction.
• Pinch Kickback can happen when the wood on either
side of a cut closes in and pinches the moving saw chain
along the top of the guide bar. This can cause the chain
to instantly stop. The chain force is then reversed,
causing the saw to move in the opposite direction,
sending the saw straight back toward the operator.
• Pull-In can happen when the moving chain on the bottom
of the guide bar hits a foreign object inside the wood. This
can cause the chain to suddenly stop. The saw is then
pulled forward and away from the operator, which could
potentially result in the loss of control of the saw.
KICKBACK SAFETY PRECAUTIONS
• DO NOT over reach.
• DO NOT cut above shoulder height.
• DO NOT make cuts with the tip of the guide bar (Fig. 1).
• DO NOT let the tip of the guide bar contact any object,
such as a log, branch, ground or other obstruction.
Remove or avoid any obstructions that might impact the
tip of the guide bar while cutting (Fig. 3).
• DO NOT cut more than one log or branch at a time.
• DO NOT twist the saw when removing the guide bar
from an undercut while bucking.
• DO NOT operate the unit with one hand! Serious injury to
the operator, helpers or bystanders may result from one-
handed operation. This unit is intended for two-handed
use. Always grip the unit firmly with both hands when the
engine is running. Keep the left hand on the front handle
and the right hand on the rear handle. Use a firm grip with
thumbs and fingers encircling the handles. A firm grip will
help maintain control of the unit and reduce kickback. Do
not let go! Stand slightly to the left of the unit to avoid
being in the direct line of the saw chain. Follow all the
Proper Grip on Handles instructions in the Operating Instructions section.
