Preparing Your Alligator Lopper TM For Use
WARNING: Read and understand all instructions. 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
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

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.
