It may not meet the ANSI performance requirements when used with other saws. • Saw Chain - A loop of chain having cutting teeth, that cut the wood and that is driven by the motor and is supported by the guide bar. • Switch - A device that when operated will complete or interrupt an electrical power circuit to the motor of the chain saw. • Switch Linkage - The mechanism that transmits motion from a trigger to the switch. 7 8 A B C D 15 E F 479970-00 LP1000 9/14/05 1:00 PM Page 8 479970-00 LP1000 9/14/05 1:00 PM Page 9 GH Contents 1.

Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury WARNING: Sharp moving blade. To prevent accidental operation, ensure that the tool is disconnected from the power source before performing the following operations. Failure to do this could result in serious personal injury. CAUTION: Sharp moving blade. Always wear protective gloves when installing or removing the chain. The chain is sharp and can cut you when it is not running. Chain tension adjustment (fig. A) WARNING: Before chain or other adjustments, make sure that the tool is switched off and unplugged. If the chain can not be correctly tensioned, it may need to be replaced. Contact your nearest service center. The product comes ready assembled. However we recommend that you check the tension of the chain, and chain retention nuts before use and if required adjust. Checking and adjusting the chain tension (fig. A) To tension the chain slacken the two chain cover retention nuts (11) with the wrench (2) and the chain tensioning device will push the chain bar out, setting the correct tension. Retighten the two retention nuts (11) securely. Check that the correct tension has been set by lightly pulling on the chain. The tension is correct when the chain snaps back after being pulled 1/8” inch (3 mm) away from the guide bar. There should be no "sag" between the guide bar and chain on the underside. Note: Do not over tension the chain as this will lead to excessive wear and reduce the life of the bar and chain. It will also lead to reduced product performance. Note: With first use and when the chain is new, check tension frequently as a new chain stretches slightly. Replacing the chain and chain bar After prolonged use the chain and / or chain bar may need 10 replacing. Use Black & Decker replacement chain RC600 only. Low-Kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1 when tested on the representative sample of chain saws. Removing the saw chain & chain bar (figs. A & B) WARNING: Before chain or other adjustments, make sure that the tool is switched off and unplugged. WARNING: Laceration hazard. Always wear protective gloves when installing or removing the saw chain. The saw chain is sharp and can cut you when it is not running. WARNING: Burn hazard. The chain guide bar and chain may become hot during use. Allow to cool before adjustment or removal. - Place the tool on a firm surface. -...
