QKICK-BACK MAY OCCUR WHEN THE NOSE OR TIP
OF THE GUIDE BAR touchesanobject or when the
wood closes in and pinches the saw chain in the cut.Tip
contact in some cases may cause a lightning-fast
reverse reaction kicking the guide bar up and back
toward the operator.Pinchingthesawchain along the
top of the guide bar may push the guide bar rapidly back
towards the operator.Either of these reactions may
cause you to lose control of the saw, which could result
in serious personal injury.DO NOT rely exclusively on
the safety devices built into the saw. As a chainsaw
user, you should take several steps to keep cutting jobs

instructions listed in the operator’s manual.
WARNING:
The warnings and instructions in this section of the
operator’s manual are for your safety and to prevent
seriouspersonalinjury.
UNDERSTANDING YOUR CHAINSAW
SAFETY DEVICES
SAFE-T-TIP® ANTI-KICK-BACK NOSE GUARD
The SAFE-T-TIP®prevents kick-back because it covers the
tip of the bar where rotational kick-back is generated.
Inexperiencedpersonsshould never attempt to cut when
the SAFE-T-TIP®has been removed from the bar tip.
Fig. 4
Users, such as professional loggers who need to draw the
tip through the cut, make boring cuts, or cut logs bigger
than the bar length, should reinstall the SAFE-T-TIP®as
soon as those cuts are complete.When cutting without the
SAFE-T-TIP®, the user must use proper techniques as
shown in the manual to avoid kick-back.
NOTE: Referto“Maintenance”later in this manual for
instructions on reinstalling the SAFE-T-TIP®nose guard.
LOW KICK-BACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can
minimise the force of a kick-back reaction by preventing
the cutters from digging in too deeply at the kick-back
zone. Only use replacement chain which is equivalent to
the original chain or has been certified as a low
kick-back chain.
As saw chains are sharpened, they lose some of the low
kick-back qualities and extra caution is required.
GUIDE BARS
Generally, guide bars with small radius tips have somewhat
lowerkick-backpotentials.
When making a replacement, be sure to order one of the
Homelite bars listed for your saw in this operator’s manual.
The proper size SAFE-T-TIP®nose guard comes installed
on the bar.Use only guide bars that have a provision for
mountingtheSAFE-T-TIP®.

CHAIN BRAKE
Chain brakes are designed to quickly stop the chain from
rotating.When thechainbrake lever/handguard is pushed
towards the bar, the chain should stop immediately.
A chain brake does not prevent kick-back.
The chain brake should be cleaned and tested daily. Refer
to“Operation” later inthismanual for additionalinformation.
RUN POSITION
BRAKE
POSITION
Fig. 5
WARNING:
KICK-BACK occurs 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. The
result is a lightning-fast, reverse reaction which kicks
the guide bar up and back towards the operator. If
the saw chain is pinched along the top of the guide
bar, the guide bar can be driven rapidly back toward
the operator. Either of these reactions may cause
loss of saw control which can result in serious injury.
Do not rely exclusively upon the safety devices built
into the saw. As a chainsaw user, you should take
several steps to keep your cutting jobs free from
accident or injury.
OPERATION
WARNING:
Even with daily cleaning of the mechanism, the
dependability of a chain brake to perform under field
conditions cannot be certified. Keep the SAFE-T-TIP
nose guard on the saw guide bar and use proper
cuttingtechniques.
ROTATIONAL
KICK-BACK
Fig. 7
KICK-BACK PRECAUTIONS
Rotational kick-back occurs when the moving chain con-
tacts an object at the Kick-back 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 may cause loss of control which can result in
serious injury.

BASIC OPERATING/CUTTING PROCEDURES
Practise cutting a few small logs using the following
technique, to get the “feel” of using your saw before you
begina major sawingoperation.
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.
