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. Inexperienced persons should never attempt to cut when the SAFE-T-TIP®has been removed from the bar tip.

SAFE-T-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: Refer to “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 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®.
