S After each use, inspect complete unit for loose or damaged parts. Clean the unit and labels using a damp cloth with a mild deter- gent.

SWipe 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 adjustments with lower end supported. Chain tension is very important. Chains stretch during use. This is especially true dur- ing the first few times you use your pruner. Al- ways check chain tension each time you use and refuel your unit.

1.Use the screwdriver end of the chain ad- justment tool (bar tool) to move chain around guide bar to ensure kinks do not exist. The chain should rotate freely.

4.Using bar tool, roll chain around guide bar to ensure all links are in bar groove.

5.Lift up tip of guide bar to check for sag. Release tip of guide bar, then turn adjust- ing screw 1/4 turn clockwise. Repeat until sag does not exist.

6.While lifting tip of guide bar, tighten bar clamp nut securely with the bar tool.

7.Use the screwdriver end of the bar tool to move chain around guide bar.

8.If chain does not rotate, it is too tight. Slightly loosen bar clamp nut and loosen chain by turning the adjusting screw 1/4 turn counterclockwise. Retighten bar clamp nut.

9.If chain is too loose, it will sag below the guide bar and needs to be tightened fol- lowing above procedure.

WARNING: DO NOT operate the pruner if the chain is loose. If the pruner is oper- ated with a loose chain, the chain could jump off the guide bar and result in serious injury.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING in the SERVICE AND ADJUSTMENTS section.

CLEAN AIR FILTER

A dirty air filter decreases engine perform- ance and increases fuel consumption and harmful emissions. Always clean after every 5 hours of operation.

1. Clean the cover and the area around it to keep dirt from falling into the carburetor chamber when the cover is removed.

2. Remove parts by pressing button to re- lease air filter cover.

NOTE: To avoid creating a fire hazard or producing harmful evaporative emissions, do not clean filter in gasoline or other flammable solvent.

3.Wash the filter in soap and water.

4.Allow filter to dry.

5.Add a few drops of oil to the filter; squeeze the filter to distribute oil.

6.Replace parts.

BAR MAINTENANCE

If your pruner cuts to one side, has to be forced through the cut, or been run with an im- proper amount of bar lubrication it may be necessary to service your bar. A worn bar will damage your chain and make cutting difficult. After each use, ensure ON/OFF switch is in the OFF position, then clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

SMove ON/OFF switch to the OFF position

and disconnect spark plug.

S Loosen and remove bar clamp nut and chain brake. Remove bar and chain from pruner.

S Clean the oil holes and bar groove after each 5 hours of operation.
