•Watch out for branches immediately behind the branch being pruned. If the chain hits the rear branch, dam- age to the unit may occur.
•Be alert for springback. Watch out for branches that are bent or under
pressure. Avoid being struck by the
branch or the pruner when the ten- sion in the wood fibers is released.
•Keep a clear work area. Frequently clear branches out of the way to avoid tripping over them.
•Long branches should be removed
in several pieces.
PRUNING TECHNIQUE
When ready to cut, accelerate to full
throttle and apply a light cutting pres- sure. DO NOT use back and forth

_WARNING: Always stop unit and disconnect spark plug wire (or disconnect powerhead from power source) before performing mainte- nance.
CHECK FOR DAMAGED OR
WORN PARTS
Contact a Sears Service Center for replacement of damaged or worn parts.
• Oil tank - Discontinue use of pruner attachment if oil tank shows signs of damage or leaks.
CHECK FOR LOOSE
FASTENERS AND PARTS
•Bar clamp nut

1.Make the first cut 6 inches (15 cm) from the tree trunk on the bottom of the limb. Use top of guide bar
to make this cut. Cut 1/3 through the diameter of the limb.
NOTE: When making the second and third cuts, rest the foot of the pruner against the tree limb that is being cut to prevent whipping of the branch.
2.Next, move 2 - 4 inches (5 - 10 cm) farther out on the limb and make a second cut all the way through the limb.
3.Then, make a final cut leaving a 1 - 2 inch (2.5 - 5 cm) collar from the trunk of the tree to avoid dam- age to the tree.
INSPECT AND CLEAN UNIT AND
DECALS
•After each use, inspect complete unit for loose or damaged parts. Clean the unit and decals using a damp cloth with a mild detergent.
•Wipe off unit with a clean dry cloth.
CHECK CHAIN TENSION
,_ WARNING: Wear protective
gloves when handling chain. The chain is sharp and can cut you even when it is not moving. Make chain ad- justments with lower end supported. Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your pruner. Always check chain ten-
sion each time you use and refuel your unit.
