OPERATION

For your safety, study this entire manual before operating the saw. Pay particular attention to the precautions and 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 serious personal injury.

UNDERSTANDING YOUR CHAINSAW SAFETY DEVICES

SAFE-T-TIP® ANTI-KICK-BACK NOSE GUARD

See Figure 2.

The SAFE-T-TIP® (A) prevents kick-back because it covers the tip of the bar where rotational kick-back is generated. Inexperienced persons should never attempt to cut when the SAFE-T-TIP® has been removed from the bar tip.

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: Refer to “Maintenance” later in this manual for instructions on reinstalling the SAFE-T-TIP® nose guard.

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 that 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 lower kick-back potentials.

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 mounting the SAFE-T-TIP®.

CHAIN BRAKE

See Figure 3.

Chain brakes are designed to quickly stop the chain from rotating. When the chain brake lever/hand guard 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 in this manual for additional information.

LOW KICK-BACK SAW CHAIN

A low-kick-back saw chain is a chain which has met the kick- back performance requirements of ANSI B175.1-2000 (American National Standard for Power Tools - Petrol-Powered Chainsaws - Safety Requirements) when tested on the representative sample of chainsaws below 3.8 c.i.d. specified in ANSI B175.1-2000.

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 cutting techniques.
